Larry,
I'm pretty creative but the flooring is concrete so that's out. At least the cost of the retro would be huge in comparison. I don't think he wants a sub that bad. But I'll keep it in mind for the 2nd floor and up.
Even then wouldn't there be a problem with cracking sheetrock over a period of time? Or even just the bass bleeding below. What experiences have you had?
Jose,
I'll take a look at the niles.
How do you wire that? LFE out of the receiver into an input with a y adapter into L/R inputs on the 2 channel amp?
Thanks,
CMack
