LSI-15's and a new guy
Hello all,
I have a pair of LSI-15's and a LSIC on the way and I am in the process of figuring out what amp and receiver or preamp to buy. I am certainly not capable of buying a several thousand dollar amp and the corresponding preamp. I've read as many post as I could to try and get the lay of the land. In my quest to find an affordable solution to my problem this is where I am at. I was looking for a reasonably priced receiver and I think I will go with a Harman Kardon AVR-235. Use the pre-amp out connections through possibly a ATI AT1505 or a Sherbourn 5/5100A. I've read good thing about both but my big thing is value for the power to drive the LSI's at a level that they like. It brings me to a question for the experts on here. If you are pushing 200w of power or more to the LSI-15's do you still need to bi amp them. This setup will be a music and home theater setup. I don't have the rears on the way yet but will probably chose the LSI-7s. This will be a 5.1 setup because I have no place to put center left and right surround speakers. What about the LSIC. With 200w going to it and not nearly the load that the 15's put on the system. Do you think it will be fine without bi-amping it? What about driving the LSI-7's with the H/K 235 outputs? With such a small amount of sound coming from the rears I would think that this would be acceptable. Sorry about all the questions. I'm just trying to not make any big costly mistakes along the way of my first decent surround sound setup. The ex took my other equipment and I decided that I would put together a kick **** system for a change. Well at least kick **** to me. Let me know what you think and flame away if desired. I can take it. I don't have a problem admitting my lack of knowledge, but at least I'm smart enough to know who has the knowledge. Thanks, in advance.

I don't see any need to ever biamp the LSi line unless you were thinking of using a tube amp up top. 150-200 wpc of high current solid state amps are plenty to get them singing.HT Optoma HD25 LV on 80" DIY Screen, Anthem MRX 300 Receiver, Pioneer Elite BDP 51FD Polk CS350LS, Polk SDA1C, Polk FX300, Polk RT55, Dual EBS Adire Shiva 320watt tuned to 17hz, ICs-DIY Twisted Prs, Speaker-Raymond Cable

Thanks for the reply. That would allow me to use the 5 channels of the amp to power each individual speaker which is what I would like to do but I wanted to make sure the 15's are getting enough. I want two channel audio to rock from the 15's.

The toughest obstacle I've encountered with the 15s are that a placement for great 2 channel sound doesn't really work with my HT projection screen setup. They like to be out from the walls farther than my rig allows and with more toe-in than other speakers.
This is an issue with my room, but I'm not the only Polkie to experience this. The side-firing woofers like to breath too, and in some locations this can be bothersome.HT Optoma HD25 LV on 80" DIY Screen, Anthem MRX 300 Receiver, Pioneer Elite BDP 51FD Polk CS350LS, Polk SDA1C, Polk FX300, Polk RT55, Dual EBS Adire Shiva 320watt tuned to 17hz, ICs-DIY Twisted Prs, Speaker-Raymond Cable

This is good advise.Dan
My personal quest is to save to world of bad audio, one thread at a time.
