The Pro10 system is the ideal combination of power and precision. It performs (and disappears) beautifully in a 200sqft room to give all the detail of the musical event with the proprietary Q-balance sound, and it can power a room of 500 sqft with the same ease and precision - to give you that full bodied feel of a live event. Audiophile Stereo or Home theatre? No limitations either way.

The Pro10 system consists of a separate satellite and powered subwoofer, both designed individually from the ground up, bringing out the best of the individual design philosophies. The combination is superbly effective too, sounding harmonious together as a whole system. With efficiency in the 94dB range and a total power of 400 W (RMS) on tap, this system is designed to deliver.

- Q-balance Technology for no listening fatigue.

- Constant vertical directivity driver configuration.

- Complex, multi-element satellite crossover.

- 24 dB/Oct bass filter in satellite.

- Active Subwoofer with Zero 3RD Harmonic Distortion.  

- Isobaric Chamber Subwoofer with dual 10” woofers.

At Lithos, we believe that the crossover is the heart of the speaker system and in the Pro10, this philosophy is extended further than in the Lithos Noa1 speaker system. To start with, the crossover is a huge 22-element engine, based around our proprietary Q-balance technology of eliminating ear fatigue. Complex response-shaping and detailed elimination of problems in the frequency response characterize this crossover system.

The mid and high sections are designed on two separate boards, preventing any chance of mutual induction, coupling or interference.

A bass filter that works as a fourth order (24dB/Oct) high pass ensures that the mids and lower mids are free of having to deliver bass, thus allowing greater power handling and cleaner sound due to reduced Doppler distortion and intermodulation distortion.

The mid-high crossover simulates a third order (18dB/Oct) Butterworth alignment - preventing excessive output from the 3 drivers and minimising lobing errors. This means a smooth, flat crossover transition with the minimal phase response problems that are typical in MTM configurations.

Diffraction rise in the midrange is also effectively smoothed out, to keep the midrange rise in check and ensure neutral mids through the effective frequency range.

This frequency rise is typical in most designs, causing excessive mid-band output. The superb, laid-back yet detailed Lithos sound is all too evident in this complex design.

The mellow, flat midrange sound is extended to the tweeter and the tweeter elements allow for 0 phase impedance all the way up to 20000Hz.

Resistors with no inductance all the way upto 40KHz and parallel capacitors in the tweeter stage, make the highs sound smooth, extended and in absolute harmony with the mids.

The use of air cores for all series inductive elements maximizes the current carrying capacity through the coils and limits saturation and harsh sounds by preventing the onset of early compression and distortion.

The complete crossover is potted with epoxy resin, to prevent mutual interference effects and to prevent the effects of air vibration from ‘hollowing up’ the sound.

We are confident that when you evaluate the subwoofer that comes along with the Pro10 satellite speaker, you will find it to be the most unique product of it’s kind - anywhere in the world. No powered / active subwoofer we know of can boast of such thoughtful and dedicated design.

The performance of this product is set to go beyond your expectations...and beats anything in it’s price range -and way more. There is so much to say, do look at the individual Terra150 catalogue for the complete technical details.

The subwoofer is built around 2 x 10” woofers, arranged internally inside a 16” cube cabinet which simulates a constant pressure, push-pull, bandpass design.

To simplify, there are 2 x 10” woofers, mounted inside a 16” cabinet, facing each other, suspended and separated by a 1” thick baffle. This system, along with the separate power module, is unique anywhere in the world.

This constant pressure bandpass system allows for halving the cabinet size without any loss in efficiency - unlike conventional constant pressure systems.

With this unique push-pull bandpass arrangement, 3RD Harmonic Distortion - a major component of ear fatigue, is completely eliminated.

This cabinet design internally compresses and de-activates excessive cone movements - because the woofers work into a fixed mass of air, thus audible distortions due to overdriving are virtually eliminated. Furthermore, this system, unlike conventional reflex systems, protects the woofers from subsonic/infrasonic frequency distortion - typically afflicting subwoofers when reproducing home theatre bass. In any case, overdriving the 2 x 10” woofers to start with - is a task in itself.

The Terra150 is again unique, in that it is a true stereo subwoofer - once again a first in powered subwoofer design. In stereo mode, the electronics of the power module does not have to sum 2 channels of bass into mono. This process of summing has it’s own inherent distortions and ambiguities. The Terra150 provides cleaner sound and better control for stereo and music.

The power module is a high current, stereo amplifier made with demanding specifications and delivers outstanding bass transients and dynamics. The amplifier comes with a balanced input/output connector per channel and can be bridged to double it’s power into a single channel. It has excellent specifications with over 100W RMS/Ch @ 4Ohm with both channels driven, >200:1 damping factor, > 20 V RMS Voltage gain, with a slew rate of 30V/µs and a THD of < 0.02% ! It comes as a separate sleek add - and is mounted as part of your equipment rack. This prevents excessive vibration - caused by the constant air pressure - from causing modulation distortion in the power module. Just think, would you like to keep your amplifier directly on top of your speakers? Imagine what would that would do the internal parts of the amplifier in the long run.

Now think of all those active subwoofers that have the power module inside the subwoofer cabinet!

Rigid bracing, high quality MDF material and a monocoque construction ensure a quality, resonance-free sound from the satellites.

A narrow profile is maintained to avoid diffraction effects, giving an overall boxless sound.

The satellites can be mounted on stands for the complete audiophile look and feel, but a variety of wall mounting options allows you to get this fantastic Lithos sound in any conceivable configuration.

Both satellite and subwoofer cabinets are designed using high tech CAD systems and are manufactured on world-class wood working lines.

The subwoofer cabinet is made from 3/4” thick MDF with a 1” thick baffle. This complex cube construction with the 1” baffle acts as a rigid shell, preventing vibration and cabinet energy storage effects - reducing unwanted resonances to a minimum. Port and cabinet design is optimized for deep, tight bass even at the lowest volume levels. The weight of the complete subwoofer cabinet is 20Kgs - 29Kgs with the power module!

The subwoofer drivers - 2 x 10” - work around a melamine coated paper material providing the musicality associated with paper as a cone material as well as ensuring adequate stiffness for break-up free excursion due to the melamine coating. A large voice coil and a ventilated pole piece ensure high power handling by dissipating excess heat quickly.

The mids use the same material as the woofers and are 5.25”. Large magnet structures maintain low Q values for a mellow yet tight and detailed sound. At 5.25”, the mids are able to dig into the 100Hz range with ease and provide superb integration with the bass of the dual 10” woofers.

The tweeter is a 1” dome, again with an oversized magnet. A low resonance point increases power handling and minimizes crossover distortion. Ferrofluid cooling along with the fabric material of the dome ensures a seamless transition between the mids and the highs.
