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!

I'm running a Polk sub that accepts the outputs from both a receiver (mono out) and my main 'pile' (L&R) without any issues.

I don't run both at the same time, but haven't tried it either.  *L*  I could send two entirely different program sources to the Polk which could be amusing to listen to for awhile...

I'd think it'd rattle itself over to me and inquire if I'm pissed at it, or merely on drugs. ;)

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...;)

Mmm....mostly likely 'sum', and you'd get 'musical MixMaster'.  As long as it's not up to 10 on both or either....IMHO, I haven't tried such with mine.

I do listen to 'odd stuff', but I pass on the straight up involuntary or even intended.  Per the later, I'd opt for some sort of control if only for the amusement of it.  But 'delays' show up in even the most benign or unforeseen places, unexpected echos(os,os,os,os,s.s.s....)

Just go forth with a little trepidation and conservative levels, as see what the results are.  As long as the volume isn't maxed, should be kewl.  Worse is a visit by the feedback daemon and you jerk the plug ("Don't Do THAT!" *L*).

Standing by....;)
