Uncompromising Performance, Our Best Value!


"These speakers’ levels of design, capability, and refinement far exceed what could previously be expected from this price range. Those considering buying far more expensive speakers would be well advised not to ignore the Ascends simply because of their low prices; you could be passing up one of the great speaker bargains of all time."
-Jeff Van Dyne, HomeTheaterSound

Equally adept at both music and movies, our 340 SE mains were designed for use from small to even extremely large rooms where high volume capabilities, extreme dynamics and room-filling dispersion are necessary requirements.

CMT-340SE DESCRIPTION

 

The natural progression of our renowned CBM-170SE, the 340SE mains will astonish you with their startling lifelike dynamics, exceptionally wide and deep soundstage and refined yet detailed presentation of music.

Being the big brother to our 170s, these speakers are capable of extreme volume levels and exceptional midbass punch.  They perform equally well for both music and movies, in small rooms or very large rooms. With their high sensitivity and stable impedance load, they will pair well with any amp or receiver, from low power to high power amplification.

We consider these speakers to offer the best bang for buck performance on the market today!

CMT-340SE FEATURES

 

  • Hand assembled, tested, and packaged in the USA!
  • Front baffle features radiused edges which reduce negative diffraction effects.
  • Wide dispersion 27mm soft-dome chambered tweeter for smooth and accurate on- and off-axis room response. Custom manufactured for us by SEAS of Norway.
  • Real woofer phase plug linearizes and widens dispersion, improves voice coil cooling (extending woofer life) and improves airflow thereby increasing efficiency and power handling.
  • Flush mounted drivers and grille mounts minimize diffraction and reduce high-frequency baffle reflections.
  • Dual proprietary 6.5" polygel woofers (composite fibers stabilized with an acrylic polymer-gel) provides exceptional stiffness yet is extremely lightweight and well damped, providing tight bass, accurate mids, extremely low stored energy and accurate transient reproduction.
  • Internally flared rear port tube enhances bass response and lowers distortion.
  • 5 way gold plated brass binding posts ensure low resistance and a secure connection to a wide variety of speaker cable connectors.
  • Advanced bi-wireable crossover with gold plated jumpers air-core inductors and metallized polypropylene capacitors in the direct signal path.

CMT-340SE MEASUREMENTS

 

*All of the measurements you see below are unsmoothed and use a 5dB/division scale where appropriate. It is common for loudspeaker manufacturers to publish measurements that have been smoothed to 1/3 octave (meaning 3 graph points per each octave) and use a 10dB/division scale. This has a tendency to make the graphs look smoother than they are.

We have chosen to be different.

CMT-340SE SUMMARY

 

An incredibly transparent and open sounding front soundstage capable of filling the most demanding rooms with clean and accurate 2 channel music or home theater.

Combine with our CMT-340SE center for a truly seamless front soundstage.

The natural progression of our renowned CBM-170SE, the 340SE mains will astonish you with their startling lifelike dynamics, exceptionally wide and deep soundstage and refined yet detailed presentation of music.

Common full range tower speakers have an appealing look but sacrifice midrange and high frequency performance in order to deliver deep bass. In a quality home theater system, subwoofers are required and reproduce low frequency information far superior to 99% of all tower speakers. With a full range tower speaker, why pay for bass twice and sacrifice the critical midrange and high frequency performance? Our 340SE mains are the ideal home theater solution, a new class of loudspeaker! We like to call it our 'mini-tower'.

With an advanced tweeter, dual 6.5" polygel woofers, high efficiency and remarkable performance, we feel we have once again set the standard for affordable and uncompromising accuracy, the best bang for buck performance on the market today!
