so those 2 little bookshelf speakers will fill my room? That don't make sense to me, but I'm newbie in this area. I thought that system was meant for a bedroom. So if I order this system, and if I buy an additional sub should it match the one that comes with it.
Thanks again
Chris
I was under the impression you were looking for a 5.1 system, no? The system I mentioned would give you 4 'little bookshelvelf' speakers, a matching center, and a sub, plus extra cash to use on a second sub. I'm not sure if you could get the same sub that comes in the system a la carte, but you probably can. You'll have to check with the respective retailer for that. You may also be able to get just the mains and center, and get a different sub (or subs) from another manufacturer for improved performance.
But, yes, such a system would probably be just great in your living room. By adding a second sub, you'll have far fewer problems with room modes and such, and greater overall bass output. This would add realism and impact that running just one sub (from within this price range) could not do.
what does high passed mean?
'High passed' is referring to the frequencies allowed to pass through an active crossover/bass management which is integral to your AV receiver. High pass simply means that lower frequencies are filtered out of the signal before your amp sends the signal to the speakers. This has a number of benefits: it spares amplifier power which otherwise would go to reproduce very power-demanding low freq signals, and it prevents your bookshelves from being asked to reproduce frequencies for which they were not designed to. The sub would be 'low passed' to pick up where the mains leave off. By relieving the load of producing low frequencies from your main amp, you will yield more available power to those frequencies which it does produce. Result: better dynamics, increased overall output, and potentially less risk to your main speakers.
If you were to use the system I mentioned, you would want to set your AV receiver's bass management accordingly, i.e. set your mains to 'small' or choose ~80Hz as the high pass cutoff.
