Hi everyone. I recently spent about $6,000 for the installation of components in a Home Theater I'm completing in my home. The room is 21' by 13' and I have a 105" wall-mounted screen and a Mitsubishi HC6800 projector. So this is not high-end. But I'm concerned that the guy who did the installation may have installed really lousy speakers for the 5.1 surround sound. The speakers he used were Pioneer S-IW631-LR for the two in the front wall (on either side of the screen) and Pioneer S-IC621D for the three in the ceiling. I'm not looking for professional sound, but these don't sound very good and what I see on line indicates that they are pretty low-end.
Are these (relatively speaking) lousy speakers, and would I notice a significant difference if I upgraded, spending a total of say $1,500 to $2,000? The bass is coming from a JAMO SUB300 and sounds pretty good.
Thanks in advance for any help!
