5.1 Surround Sound using towers

822 Views 7 Replies 3 Participants Last post by  Secret Squirrel

Theoretically would it be possible to use speakers in a 5.1 setup for the FL, FR, SR, SR, and SL?  Anyone have any thoughts or attempted doing this?  I'm curious if it works.

Sure, it can work. You just need to be able to get the speakers at the proper height with the listening posting. The tweeters need to be at the right height on their own or angled up or down for the most direct path to the LP. My theater has mostly large towers. Don't be fooled by trying to make them dig to deep though. I use an 80hz crossover. It gives the best dynamic sound and blend with four big subwoofers.
Well…I have two Klipsch F30s for fronts and thought about two more for the rears. I have a Klipsch center and Paradigm sub. But you are saying I could get two more f30s and it would sound good? Should I also be biamping these towers?
Do not bi amp the towers. It will do nothing to add to their sound or provide them with more watts. Adding two more towers should sound fine. Do you need them? Probably not. Surround speakers are usually fine being a smaller speaker then the mains. If you have the room for towers all around in your room it can be a great system as long as you set your crossovers correctly. Many people fall into the trap of trying to play their tower surrounds to low just because the speaker is big. I have huge mains, a large MTM center channel, three way towers with 10" drivers for surrounds and large 6" two way book shelf speakers for rear surrounds. All matching speakers from the same line. They're all crossed over to 4 subs at 80hz because it gives the best bass response. The 80hz crossover is a fast 4th order crossover. My system sounds very dynamic and tight because every speaker is doing its job correctly. My side surrounds can play much lower but I won't lower the crossover because the sound isn't as good.

Sorry about the late response, I thought it posted on my iPhone, but timed out :(  Anyways, are you saying biamping is pointless?  Are there any real benefits to doing it then?  I don't understand the point in having two posts on towers if people say not to biamp them.  Also are you saying I should set my crossover at 80hz?  I didn't mention the receiver I have but it is a VSX-823-K...but I am thinking about upgrading that even though its only 4 weeks old.

Yes. This is called passive biamping and is useless. Active biamping is not and has many benefits. Plenty of threads on it here.

Some people believe that bi wiring and passive biamping makes a difference, so speaker manufacturers add the extra posts not to lose sales to those customers. AVR manufacturers do it because it is a no cost option to add a 'feature' that appears to value add and lets customers think they are not wasting the channels that would be unused in say a 7.1 set up and the AVR has 11 channels of amplification.

And WRT the initial question in this thread, in an ideal system, all channels would have identical speakers.
So active biamping, multiple receivers, is the only "true" way to biamp, correct? If I'm only going with a 5.1 setup and have the f30 towers, what is the best way to maximize the power to the speakers? Right now my receiver is pushing 80 watts to each tower that can handle 150W RMS and 600W Peak!
Klipsch speakers are efficient. The best way to get the most power to your speakers is to properly place a good subwoofer in the room and utelize bass management. Doing this will take a load off of your AVR utelizing your mains and other speakers to produce the upper and mid frequencies. Leaving the low power sucking frequencies left for the subwoofer.
