R30 Ribbon Driver

30" Ribbon Midrange Tweeter

The R30 is a classic design Ribbon used on our R630v3 model.  It has hundreds of fans around the world.

 The R30 is designed as a top mount Ribbon for use above the cabinet housing the midbasses.  Good efficiency, wide dispersion and superb soundstaging are the basis for the R30s classic status.

 Simply put, nothing gets out of the way of the music like an R Series Ribbons.  Excellent dynamics and the ability to achieve a very high level of transparency at high or low levels make the R45 suitable for a broad range of applications from low powered stereo systems to home theater to small public assembly sound systems.  The R30 has a very high and even impedance.  Any amplifier will safely drive it.

 For speaker kit builders, a simple 6dB (single capacitor) crossover and good quality midbasses are pretty much the only ingredients necessary to assure superbly musical results.  Aim for a crossover of around 1kHz and when placing the speakers, try and give them as much air as possible.  Very high end audio in a stereo or home theater system can be achieved with very modest effort and investment.

Audiophile Crossovers

AUDIOPHILE CROSSOVERS

Active crossovers means the system has to have an amplifier for each  driver.

Many people have been amazed and delighted with the Behringer DCX2496. Its capabilities are truly incredible and the flexibility and ease of configuration (once you get on top of the steep learning curve) have been a joy to many audiophiles and more than a few speaker designers. With pricing under $300 its price/capability ratio is off the scale. Somewhat spotty QC and problematic distribution policies have been the flies in the ointment. However, quality may be improving over the past few years and the price hasn't budged.  Note that several companies upgrade the Behringers for improved sound quality.

There are other similar products.  Here is a summary of the crossovers we know of. Most are from the pro world and require XLR connectors but Marchand is a well-known audiophile supplier.

Basics of High End Audio

Or - How to get great sound while avoiding the technology blackhole.

The world of high end audio is a very murky place for many interested in music and high performance home entertainment systems. Unlike video where a shopper can clearly see differences in performance between different sets, high end audio forces a person to evaluate performance in a much more complicated way. Volume levels, source components, amplifiers, cables - you name it - there are a huge number of variables. How do you know what you are really listening to? Not only that, competing technologies and formats and equipment priced at astonishing levels make you wonder if a reasonable choice is possible at all. 

When you buy a TV, what you see in the store is just about what you will get in your home once the set or projector is properly calibrated. With audio, all of the components are different and your room is certainly not the demo room. 

Very experienced audiophiles can pick their way through these issues. But how does the inexperienced audio shopper with visions of the enjoying real music or life-like movies in the home make the right series of choices? How can Newform Research help in delivering a dynamite system for less than stupid money? And without tearing the house apart? 

Newform makes a unique line of new technology loudspeakers which will produce superb sound quality in most average rooms. The investment in electronics to drive our loudspeakers can be quite small and still achieve excellent results. Having said that, the better the source components are, the better the sound will be. There is a price ceiling however beyond which there is probably no acoustic benefit. Above $10,000 in electronics, "prestige" and flim flam are the items being purchased. Newform Research Ribbon loudspeakers will not restrict the performance of your system. See our "You Can't Go Wrong" page for ideas on systems and various levels of packages. 

Are Ribbon loudspeakers a valid and current design approach? Over the past 30 years the most experienced audiophiles and music lovers have coveted Ribbon and electrostatic loudspeakers as the first choice for their dream systems. Real world considerations may force compromising on conventional dome/box loudspeakers but once knowledgeable audiophiles have heard a good planar loudspeaker, they have been dissatisfied with anything else. 

Transparency, detail and you-are-there soundstaging are the principal qualities that have separated planars from conventional speakers. The clean sheet Ribbon technology from Newform delivers the best sound qualities of the finest planars in room friendly systems that can be driven by very modest electronics. Our wide dispersion columnar radiation pattern is more likely to deliver superb sound in more normal rooms, for more people, than large dipoles (sound comes out the front and rear), horn loudspeakers or dome tweeter systems. Our Ribbons have excellent room coverage but minimize fatiguing reflections from the floor and ceiling so the soundstage stays three dimensional and clearly focused. 

Many higher end loudspeaker manufacturers are moving to small Ribbon tweeters. These are certainly an advance over their past designs but with their short heights, high crossovers points and baffle mounting, they fail to utilize a great deal of the potential realized in Newforms large, free standing Ribbon systems. 

Our new Coaxial Ribbon LineSource designs come in at higher price levels than we have occupied before but they offer significant improvements in both fidelity and practicality over most loudspeakers, regardless of price- conventional or planar - in most listening rooms. They are just as electronics friendly as our other speakers and thus, for $15,000 total system cost, it is possible to atain ultra system performance. 

WHAT DOES IT TAKE TO GET INTO HIGH END AUDIO

Your room must accommodate high quality loudspeakers and a reasonably favourable setup involving both the loudspeaker placement and the listening position. This typically means a room 10' x 14' or better. For dedicated rooms, you can start out slightly smaller. 

You have to have a system budget of $2500 plus. A lot of money to the uninitiated but a laughably small amount for the jaded audiophile. However, a pair of R630s or LineSource Monitors, with a $200 DVD player and a modest receiver (say Panasonic XR57 for $400) will deliver very, very decent sound in a reasonable room. Such has been the progress in the electronics world in recent years. 

You have to have a kernel of real commitment. No matter how much you spend, or how perfect your room is, you will have to plan a little bit and do some experimentation before any system can start operating near its potential. We will work with you on the planning and be there to offer suggestions on optimizing your system.

You don't have to bleed for fine music in the home. Some quiet reflection plus several minutes on the phone with our designer can quickly lead to the development of a simple and successful strategy. 

Once you realize what is substance and what is smoke, achieving great sound on a reasonable budget is very easy. Tearing yourself away from the music then becomes the difficult part. 

Subwoofer Setup

Seamless subwoofer integration requires the sub to be placed in the location which minimizes room modes and also produces the fewest cancellations with the main speakers. 

As always, get the physical issues optimized and the electronics will have a lot less processing to do. 

Listed below are some of the high end subwoofers which almost guarantee excellent bottom end performance. 

Older design subs take a little more work. Many include lossy passive crossovers which roll off the main speakers but rob a good deal of transparency. Use these with extreme reluctance! 

Many receivers have bass management which forces a high 80Hz crossover. You should aim for as low a crossover point as your main speakers can safely handle. 

In the end, any of these systems will produce superb results with Newform Ribbon loudspeakers, especially the new LineSource models as crossovers can be very low and in many cases, the main speakers can be run full bandwidth. 

Different room correction and integration systems from different subwoofer manufacturers may produce different results depending on room size and the problems the systems are called upon to fix. This has to do with how the systems handle long time delays in larger or open rooms. However, in “good” rooms, it is unlikely that the results will be anything less than excellent with any of the systems listed below. 

Velodyne is a famous subwoofer maker for good reason. We have used their subs at a number of shows and now they come with very sophisticated integration and self-equalization systems. Their approach is unlikely to be significantly improved upon in a decent room.

Paradigm is a speaker manufacturer with an excellent name for great subwoofers at great prices. Their Anthem division produces quite sophisticated processors and amplifiers and their expertise has been applied to their subwoofers. 

www.paradigm.com/en/paradigm/subwoofers-paradigmperfectbasskit(pbk1)-series-1-5-30.paradigm 

Our perennial favourite product for biggest bang for the buck, the Behringer DCX2496 is a sound reinforcement digital crossover with an incredible array of capabilities. If your subwoofer does not have room correction or a sophisticated crossover built in, then the DCX2496 will offer the next best thing. It is an extremely sophisticated crossover with some basic room correction capability via parametric EQ. It has a steep learning curve but being able to modify settings in the most minute detail on the run is a huge plus. Nothing comes close for the money. 

www.behringer.com/EN/Products/DCX2496.aspx 

Maybe the most elegant solution of all, the Tact gear has digital crossovers built into their digital amplifiers. As well, probably the worlds most sophisticated room correction is built into their preamp processors. They don’t come cheap but by audiophile standards, the price for this capability is very reasonable when you boil it all out. 

www.tactlab.com/AutomaticRC/automaticRC.html 

A sophisticated digital crossover with room correction system, the DEQX hails from Australia is very well regarded. It does as much as the Behringer in the crossover department and adds full room correction. It is also reputed to sound a bit better than the Behringer due to its higher grade DACs. It is also over 5 times the price.  

www.deqx.com  

Major mass consumer electronics brands are now offering room correction and more sophisticated bass management in their receivers. In the past, these have been less than ideally implemented but keep an open mind because these companies have plenty of resources and they are now in the realm of digital where everything gets better and cheaper at the same time. Mostly.

Speech Intelligibility

Many people notice their hearing declining as they grow older. 

Hearing loss does come with age but that is no reason to abandon music. Reduced speech intelligibility can be disconcerting but musical appreciation does not suffer with age. In fact, music can add a great deal to the enjoyment of life. 

High resolution audio is a weapon against middle age hearing loss just as a good workout is a good defence against heart disease. 

The cleaner music is, the less stressful and more satisfying it will be to listen to.   Like moving from a crowded, noisy room to a quiet environment, a well setup high end audio system will delivery a relaxed, intelligible, and highly musical experience. 

Ways to improve intelligibility include elimination of noise sources and reduction of strong and discordant reflections. Strong slap echo becomes more disconcerting as age increases so take extra care to reduce, damp or break up bare walls or glass surfaces. 

LineSources (line arrays) and Ribbons dramatically reduce the ceiling and floor slap echo to which conventional dome tweeter based systems are prone. 

Listening fatigue and intelligibility are inversely proportional.   In a public forum poor intelligibility results in loss of focus of the audience and a much less effective presentation.   In a home environment, lack of clarity results in progressively less time spent enjoying music and movies.

Our hearing changes over the course of our lives and so does our sensitivity to certain types of noise and response anomalies. We can’t fix, but we can re-adjust effectively.

Loudspeaker Reviews

Unless backed up by methodical and appropriate measurements, loudspeaker reviews can be very unreliable.

Acoustic measurements which reliably represent human perception of loudspeaker performance have yet to be developed. The basics are clearly in place though. Smooth frequency response both on and off axis, low driver distortion, low speaker cabinet colouration are all well established prerequisites for excellent performance. 

The variables from there however are many. Clearly some speakers perform better in some rooms than in others and some are designed for specific placements. 

Dispersion patterns and driver placements on the baffle have a dramatic effect on measured response at different microphone positions and distances. Reviewers who insist on a standard measuring position or distance that the speaker is not recommended for, can seriously mis-represent a loudspeakers performance. 

Distortion is something we have always assumed was a critical indicator of sound fidelity. However, once it drops down to a certain level, it ceases to be a reliable indicator. Note the Panasonic digital amp receivers which Newform has so often endorsed. The distortion on the original XR45 model was 0.9% at its rated output of 100w/ channel. On this basis alone, the receiver would be laughed out of any room populated by audiophiles. However, upon hearing the receivers, many experienced audiophiles dumped their much more expensive, better measuring and well reviewed amplifiers for these cheap little lightweight receivers. 

Ditto tube amplifiers which also add, in many cases, alarming departures from flat frequency response. But many rational people still love them! 

Everyone hears differently and everyone listens for different things. Be very careful when a reviewer waxes poetic about a loudspeaker (or other audio component) whose measured response looks highly flawed. 

Ditto for reviews conducted in poor listening rooms. Rooms that are highly unrepresentative of the average room have to be viewed as Distorting the review. If the reviewer doesn’t describe his room, and you are seriously considering the speakers based on his opinion, by all means email him and ask about his listening conditions. 

Loudspeaker reviewing, whether in print or on the web, is a highly variable process so get as much background as possible on the reviews of loudspeakers which really interest you.

Loudspeaker Merit

SPEAKERS OF MERIT

There are over 3000 different hifi stereo and home theater loudspeakers on the audio market at any one time in North America and Europe. 

Of those 3000, only a very small proportion hold any interest for audiophiles. Once the models designed to hit a low price point are taken out along with units whose aesthetics were more of a consideration than their acoustic design are eliminated, the list gets a great deal shorter.

Drop the cheapies and the throw-together from available parts and you have maybe a few hundred speakers which are well designed and well executed.

Of those few hundred, only a few score are exceptional. Loudspeaker designs have been improving steadily and there are quite a few excellent implementations of classic designs and a handful of novel designs which actually work well. 

However, some speaker designers and more likely their marketing departments keep on dredging up well known failed concepts which should have been left behind decades ago. Anything which produces a specific effect or adds character should simply be left in the archives. Loudspeakers whose cabinets resonate like a violin or other instrument should never see the light of day. Ditto speaker diaphragms with cones of some “natural” material which reproduces certain instruments with sympathetic resonances. 

Driver alignments on the baffle which create all kinds of interference and comb filtering and a host of other well known speaker design sins keep on being repeated. But not by the designers responsible for the speakers below. There may be better lineups of speaker designs out there but these are the ones we can vouch for in no particular order.

VANDERSTEEN

Vandersteen has dealt with minimization of baffle bounce, diffraction and phase alignment for many years. Add quality components, very solid cabinets and well honed design and you have loudspeakers which stand up well in any company over the long term.

WILSON

Wilson has occupied the upper end of the loudspeaker market for many years. Obviously their design philosophy is far removed from Newform’s but we can’t ignore their dedication to quality. Their pricing may be over the top but they aren’t all hat. Quality of components, construction and finish plus installation service justifies their stratospheric cost. Also, we have to applaud David Wilson’s down to earth endorsement of affordable but superb electronics. Unique openness for a high ender.
