LineSource Monitor Triple

The LineSource Monitor is quite a powerful package to start with and when stacked 3 high, (or four - really the ceiling is the limit), takes control of a rooms acoustics as few other loudspeakers can.   It virtually eliminates ceiling and floor reflections while establishing a very broad and deep soundstage over a large listening area.  The listening area is both wide and tall allowing movement without a loss of musical enjoyment for a considerable number of people.  In a public assembly area, the Triple Stacked LSM offers excellent musical coverage and speech intelligibility in rooms to 2000 square feet and audiences up to 80 people.  Tremendous dynamic capability with the expected Ribbon transparency and detail.  A world class loudspeaker with a down home price. 

No Holds Barred LineSource Monitor Triple

A world class loudspeaker system suitable for any room with any electronics, the NHB LineSource will reveal the musical potential of the upstream electronics and the nuances of the music being played to the greatest extent possible.   The NHB version of the Stacked LSMs has all of the advantages of their smaller sibling but adds slightly larger cabinets plus the bass extension and increase transparency of the famous ScanSpeak Revelator 5" midbasses.  


Being LineSource Monitors, there is no limit to the configuration options from the point of view of height, full length Ribbons and finish.   Since the systems have very high impedances as well as efficiency, there is very little in the way of restriction in the choice of amplifiers from single ended tube amps to digital ICE amps to behemoth Class A amplifiers.


Given the low end extension and dynamic capability of the NHBs, if you decide a subwoofer is required, the choice is wide open as integration is simplified by the low crossover point.


Room correction?  Audiophiles know that the less work room correction systems have to do the lower the strain will be on the amplifiers and the computing resource of the correction system.   Transparency of the whole system can only be improved by the high level of reflection control of the No Holds Barred Line Sources.


Ultra audio performance at audiophile prices.  Simple systems built to a very high standard which work extraordinarily well.

LineSource Monitor 528

The 528 features dual Peerless heavy duty 5" midbass drivers and large 8" Ribbon driver, all in a compact package suitable for any point of a stereo hifi or home theater system.  All the capabilities of it's single midbass sibling the LSM 58 but with added bass reach and dynamics.

The LSM 528 can form the core of an impressive home theater or stereo audiophile system with modest amplifiers or receivers.   Call or email us for component advice.

Oval 45 Ribbon

The Oval 45 is designed for use in Coaxial Ribbon LineSource configurations.  It is a high efficiency, neodymium monopole Ribbon with wide dispersion, high impedance and excellent dynamics.


The Oval 45 features high impedance and high sensitivity so it will partner extremely well with a wide variety of amplifiers and electronics.  It's low crossover point of around 1kHz allows a seamless off axis response to be achieved when used with audiophile quality midbasses and woofers of 7" diameter or smaller. 


The result will be exception transparency and dynamic levels from a simple system well within the ability of any loudspeaker kit builder.

Custom Loudspeakers

Newform offers a range of loudspeakers which covers a very wide range of room sizes and applications. However, many audio enthusiasts have their own specific vision of what they would like to see in a loudspeaker and how a loudspeaker should fit into their room. So for very specific applications, technical visions and aesthetic requirements, Newform offers unique solutions. 

Midbass drivers, cabinet dimensions, finishes can be mixed and matched to your specific needs. In our 1" MDF midbass enclosures as well as in our curved wall cabinets. 


3" to 7" ScanSpeak, Accuton, Eton, Vifa, Seas, Peerless - basically any high end drivers. 


We can accommodate various wire types and sizes for internal wiring but it must be of a kind which will not stress the terminals of the drivers either during operation or shipping. 

The crossovers can be mounted internally or externally and almost any kind of binding post can be incorporated into the loudspeaker construction. 

Cabinets can be made using two different types of construction. The first is the conventional 6 sided cabinet optimized with v3 technology and the second is the curved side cabinets.


Height Width Depth 

- v3 technology 6 sided - 12" - 38" high,  8" - 16" wide,  8" - 20" deep

- Curved Side - 12" -  48" high (no limit on stacking), 8" - 16" wide,  10" - 22" deep



Cabinet cladding - oak, maple, cherry and a wide range of veneers and laminated


 Corian/Solid Surface Tops / Bases

Veneer Tops

Steel Tops/Bases




 If you specify your own choice of midbass driver or a mix of our current midbasses which will represent a mismatch of sensitivities between Ribbons and midbass, then you will have to include an electronic crossover and biamping in your plans. 

The good news - very high sensitivity and high impedance SE tube amp friendly designs are possible particularly with tall LineSource and our Neodymium Ribbons.

If you would like to proceed with a custom application, keep in mind that we will be starting with extremely high quality midbass drivers and our own superb Ribbon drivers. These will be incorporated in excellent midbass enclosures so the musical results will be there in the end. You’ll just have something that fits your life a little better than any other loudspeaker in the world.

R45 Ribbon Driver

R45 Ribbon Midrange Tweeter

The R45 is a classic design Ribbon used on our R645v3 model.  It has thousands of fans around the world.

 The R45 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 R45s classic status.

 Simply put, nothing gets out of the way of the music like an R45 system.  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 medium size public assembly sound systems.

 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.
