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!
#Xm26 tube electronic crossover network kit series
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. For example, a 2-way XM44 can easily be set with 6 dB/oct on the high pass and 18 dB/oct on the low pass by choosing appropriate frequency modules.I had tried electronic crossover before just for subwoofer with satellite small main speaker. Note that the slopes on the low, mid and high channels can be different, so asymmetrical slopes are possible. When choosing slopes of 24 dB/octave and 48 dB/octave the high-pass and low-pass outputs of the crossover are always in phase with each other (Linkwitz-Riley alignment). Normal slope is 24 dB/oct, 4th order, constant voltage, but modules for first, 2nd, 3th, 4th, 5th, 6th, 7th and 8th order slopes are also available. Each frequency module has the capacitors and resistors that set the crossover frequency and slope for that channel. The crossover frequency of XM44 Electronic Crossover Network can easily be set by replacing frequency modules. The XM44 Electronic Crossover Network is a very flexible crossover design that provides individual outputs for 2, 3 or 4 frequency bands on the 2- 3- and 4-way models respectively. Options: Balanced outputs/inputs, baffle step compensation, notch/boost filters, delay sections and bass boost filter (Linkwitz transform). No transients during turn-on or turn-off. Heavy duty gold plated RCA connectors for input and output. Any slope available (6,12,18,24,30,36,42 or 48 dB/oct) Asymmetric or symmetric slopes (different slopes can be mixed) Crossover frequency 20Hz - 20 KHz. Steep 24 dB/octave 4-th order slope (Linkwitz-Riley) standard. XM44 Electronic Crossover Network Available 2-way, 3-way or 4-way.
