Axiom Home Page Forums General Discussion Technical Questions Integrated + Sub

on your Cambridge Audio 640a ( i assume you have de v2.0 )
has no LFE output, so, your sub will be driven via the PRE-OUT.

simply ajust the output gain of the sub the volume of your amplifier & the sub volume will follow.

I assume that you are an audiophile & a small part of your listerning time are for movies.
I don't know about the performance of the M3's but i think that your choice for EP125 is little bit too small for movies applications. EP175 could be better & EP350 great !!! if you can afford them. Because on movie application you need more DEEP & PUNCH.

I own a Cambridge Audio 640r wich is mostly the Home theater receicer of your 640a. Actually i'm at 2.0 & for me adding a sub will be only for movies applications, so I'm looking for EP350 or EP500 (if a can afford the).

I think that you choice of an EP125 will be nice for music listerning but some deepness & punch will be missing on movies.

Dr House's advice for calibation are right

Good luck Phillippe !!!
