The XM9 crosses over the frequencies to their respective amplifiers without distortion or coloration, no noise or phase shifts are added and the results are superb. In all respects this configuration has performed flawlessly, once set it can be forgotten! By choosing a frequency of 90Hz or less the bass information is non-directional and the receivers amplifiers are not taxed by having to reproduce the bass. Left/right pair, all others to small and redirected the LFE to the mains.

With the music and Pro Logic sources the signal dispersion happens without any other set-up steps, with Dolby Digital I set the speaker size to large for the main With the XM9 in the receivers pre-out/main-in loop I can effectivly send the bass information to the amp/subs leaving the high pass information to the mains. What I wanted was a way to handle the bass for music sources as well as Dolby Digital and Dolby Pro Logic without having to throw sitches and set levels each time I changed sources. I felt that the Crown colored the sound with the introduced phase shift and a ground loop hum, not to mention the Crown does not have a 'soft turn on' delayed on/off power sequence which can cause theĪlways annoying and sometimes damaging speaker THUD! While not going into step-by-step detail, you can get a good feel of what is involved if trying to build this unit from kit form.įor over a year now I have been using the XM9 to handle the bass management chores in my Home Theater/Sound Room, it replaced a Crown VFX-2 (variable frequency 18dB/oct high/low pass xover). I have posted my experience while building this kit on my website. The quality of this unit is first rate, from the heavy steel chassis to the circuit boards. The XM9 does this, and does it extremely well!

After building a pair of BESL Series 2.4 MTM monitors and BESL Single CSX-10 sub modules, I needed a component to handle the crossover duties in my bi-amped system. As mentioned in the other reviews for this product, anyone that knows which end of a soldering to hold can build this kit and save themselves some dollars. I purchased the Marchand XM-9KK, which is the kit form of the crossover. cabinets based on Altec 620 cabinet, but with shelf braces and 1.5 inch thick panels (baltic birch and MDF) all around. I've written to Marchand Electronics to see if they think the crossover needs servicing.Īltec 604-8K speakers in custom 8.5 cu. It's just mid-fi boring sound now.Īnd, to make matters worse, the crossover produces so much speaker hiss that you can plainly hear it 6-8 feet away It's so bad it interferes with quiet acoustic passages. Transients are blurred, the sense of liveliness and "presence" is gone. Overall, compared the the stock passive crossovers I was using, this configuration sounds muffled, as if someone just hung several layers of cloth over the speaker cones. Finally, I got the extra power amp and interconnects and the XM-9 crossover and was ready to try. Pro audio friends have told me for years that if I try active biamping, I'll never go back to passive crossovers. So far I am thoroughly disappointed in this crossover. I'm guessing this XM-9 is a pre 1995 model because of the extremely thin power cord (thinner than the cord on my clock radio), but I could be totally wrong. The results is much more than I expected! Every kinds of music become more transparent, more speed, more detail, more power, and more linear across a very large range of sound pressure!Ĭonclusions: If you could diy, try it! It is 100% bargain while it is 100% high quality of sound! If you could not diy, buy it assembed if you need a electronic crossover!

The sound level adjustment between three frequency bands were assisted with frequency generator and AC meter, then final level adjustment with HiFish AC controller and HiFish test CD. Connetion cable are Mogami #2791 and pure OCC 1mm. The power supply are mono-mono with local well-design +- 15V power supply () (not 78). I think everyone will believe this electronic crossover had been well design by Marchand after reading of the manual! The op IC are sixteen OPA2134 and the resistors are PH 1% or 0.1%. After carefully reading of the well-written assembly manual, collection of the quailty parts and suitable case started with 100% confidence. Hence, this XM9 electronic crossover journey began!įor experimental purpose, I just bought four XM9 PCB from Marchand Electronics Inc.

This time I'm curious whether a 3-way electronic crossover + tri-amp combination could beat a very good passive crossover (quaility parts and fine tuning) plus a very good power amp. However, last experience did not amaze me at all. I had tried electronic crossover before just for subwoofer with satellite small main speaker.
