Dual-Use Subwoofer?

Not quite sure where to put this question - hope it’s in the right place.

My HT and audio systems are separate because my ’good’ stuff is reasonably good, my ’ordinary’ stuff is pretty ordinary, and I don’t want to ’taint’ the good stuff with ordinary stuff.

HT ’boxed’ system:
HK AVR254
Infinity surrounds & sub (sub fed by LFE from the AVR)

Audio:
Krell KRC-3
Bryston 4B-ST
Martin Logan reQuest
Polk PSW650 (signal fed by the preamp)

Because I live in a space-constrained home and want to give the ML’s the ’breathing room’ they really need, I’m wondering if it might be possible to ’consolidate’ by using only one Sub. The Polk unit is the more musical, definitely more than adequate for HT, has both LFE and Left/Right analog inputs, therefore would be the obvious choice.

Do you guys think it would be possible - or at worst, risky - to use the LFE input from the AVR and use the L/R analog inputs from my preamp for the higher-end stuff? I just don’t know my ass from a hole in the ground about electronics and don’t want to risk burning anything out in either the sub, the receiver or the preamp.

Thanks in advance!

You might want to consider using a miniDSP solution. If I understand correctly, you want 1 sub hooked up to 2 sources?

MiniDSP will let you do this AND will let you do EQ and crossovers separately for each source.

Best,

I think a mini-dsp is more complicated than this requires.

My plan is to set the tonality of the SW to the audio system, and use the AVR to conform to that adjustment since the outupt on the receiver is variable.

My worry was simply with the possibility of signal from the Krell damaging the receiver, or vice-versa.

We're good to go.  Thanks!

Erik's right, if you've the desire for that level of control.

In my case, the mains have 'all the bells 'n whistles' (stand alone digital eq & xover) and the rcvr can either act like one or just act like a 'dumb box' amp, accepting a signal from elsewhere....

With the above And the digital eq in the 'puter, I can have exquisite control or gross deviancy...*L*  I tend towards the former....mostly...;)

My AVR has settings in the DSP for crossover and volume output for the sub and main speakers. Once I have the sub dialed into the audio system, I can tweak the receiver. I think no extra equipment will be necessary.

Let us know what happens.  We're all ears....well, eyes, anyway. ;)
