    Default Dumb idea...or not ? Poor man's Bi-amp idea

    Ok, just brought home a nice pair of RTiA7's on the weekend, however...an incredibly stupid idea has entered my head, head this one out...

    I have a lower end Yamaha AVR receiver collecting dust, thinking about putting it in my bedroom system displacing the HK 3375...now here's where the stupid idea really starts...bi-amping the RTiA7s !

    Idea... purchase a pair of RCA Y adapters, 2M plugs-1F jack, remove the Pre Out-Amp In pins from the HK 3490 and placing these Y's in place keeping the pre and amp connected then using that receiver to power the lower woofers of the towers, then run an RCA cable to the Amp In of the 3375 to power the midrange and tweeter of the towers. Lower half would be getting 120 watts a side and the upper portions would be getting 75 watts per side, grand total of 195 watts a side, bi-amped with emphasis on the lower end of the sound...am I nuts or ?

    I did check the posts on the back of the towers, upper connectors are the 6.5 inch and tweet, the lower connectors power up the dual 7 inch woofers.

    Like I said, poor mans bi-amp...worth it ?

    Like I said in your other thread, find someone to hold your hand locally. I see you having the potential of getting sucked in to this hobby, but you want to do it the right way. Don't take it as a insult as I went down that path myself - I speak from experience. Sitting in a fellow audiophiles room and talking about the pros and cons is of his system is invaluable and much more powerful than a forum, especially in the early stages of the hobby.

    Ps - don't do it.

    He already has it biwired to a single receiver and refuses to hook it up normally even though he says he knows it's not beneficial. He's going to do this anyway. No offense meant.

    A big fat no.....and if you read up on any threads around here you'll know why. But in the end, it's your gear, your coin, your ears, do with it as you will.

    Enjoy what you have for now - as is. Don't crank it too loud with the receiver. Then save up an buy a used amp if you have preouts to improve SQ.

    Love them, they have been playing on low low volume since Sunday night albeit with the bass knob twisted full tilt, again, LOW VOLUME ! Just to loosen them up and break them in, turned the bass down to flat when I got home from work and turned up the volume to a moderate level, the low end has gotten a touch richer, the mid and high has smoothed out a bit too. Still gonna let em go 24/7 at low with the bass turned up for break in purposes.

    I'm not the one interested in seeing what it's like. A real audio enthusiast always does their own wiring work. I already did 250ft of wiring in my theater, no more ....at least for another week or so. Upstairs theater will have to do the same soon.

    Nah, the ones who know say it's a bad idea so I'm not going to do it. Besides it's three+ hours of work to pull off, not worth it.
