Axiom Home Page Forums General Discussion Advice from Axiom Owners Bi amplification

Hey Adrian. According to a long thread on the A500 either on avsforum or audioholics there can be quality issues with the A500.

Tks, I'll check it out.

I still find it odd that this technology has been around at affordable prices for a long time in the mobile audio side, but remains rather esoteric in the home environment. My Alpine head unit in my SUV has active 3-way parametric crossovers in the digital domain. It is great to be able to change the crossover point from 80 at -12db to 63 at -18 if that works better in your setup, or as you replace speakers. I confess, i leave the passive crossover network in place on my expensive separates just make sure i don't screw it up by accident.

Surprised this simple bit of code/chipset has not been dropped into a decent Denon AVR for real use of the 19 amps they are dropping into their AVRs these days.

And the speaker companies would love it - just think how many DIY'ers would blow the tweeter across the room seeing if it could handle a 1000 hz signal! It would open a whole new market for replacement parts.

Charles, just a point re amplifier terminology relevant to your "19 amps" comment. A receiver has just one amplifier with multiple output channels. So, despite the terminology in some manuals, a receiver can't "bi-amp", even if some of its 7 or 9 channels(the 19 channels will be in next year's "upgrade") aren't being used otherwise.

No, I fully realize that. I just mean that its a tricky addition to allow people to do custom cross over setups as discussed above. Agreed, it gives no extra power, etc. But you could build a custom speaker and not mess with a complex passive crossover if they had the digital crossover network I'm referring to routed via ch 1&2 - high, ch 3&4 mid, ch 5&6 mid-bass, ch 7&8 bass, etc. And if done in for pre-amp outs, you could set up a true bi-tri-curious configuration.
