So it is hard to tell, but it seems my setup doesn't have as much bass/low end as it used to. I thought I would start here for troubleshooting.
I built/setup this system back in 2006 I think.
57" Mitz DLP TV
Paradigm Cinema 110 CT 5.1
Media PC with a MSI 4550 video card
I now have a different TV, Samsung 65" LED but doubt that makes a difference in sound
So mainly I'm concerned with playing movies from my media PC. I have it connected to my 2700 via HDMI cable to the DVD port. Then 2700 HDMI out to TV. My room is open concept, slightly vaulted ceilings and about 14'x25'. I know someone might say I need a bigger speaker system and that might be true, but I swear when I first set everything up, playing movies like Transformers etc shook the room a lot more.
On my 2700, I have it set to Straight and PCM. The display shows MPCM on a DTS movie for example.
LCR and surround speakers all sound good and seem to work well.
I have tested using THX youtube video and other sound tests from youtube. Unless I turned it way way up, my sub just doesn't seem to hit as hard. On my 2700 I also turned bass all the way to +6 under tone control. On the sub I have messed with its settings and even turning it as low as it will go. I have never played audio really really loud so it shouldn't be blown or damaged from that. Plus I still get some base, just as stated not as much as I recall.
Any idea? I guess other thing that might have changed are video card driver updates but I'm guessing it is just passing audio through the HDMI and my 2700 is handling all that.
My little 5.1 yamaha system on my main computer shakes my office more playing the same movie.
