The above posters are correct. You can also access the Oppo menu's to adjust the display height of subtitles. It's set at -5 by default (not sure why). Set it to zero and you should be fine.
I'd also add that if you have the center speaker sitting actually on the concrete floor, I'd look into putting it on a stand to get it away from that immediate hard surface which is probably affecting your dialogue the most.
Well, another poster pointed you in the right direction with the Epik Conquest. The bad news is they don't make the Conquest anymore. It's a shame cause it's a terrific sub, if a bit on the large side.
Epik still makes some other great subs, but not with the extension the Conquest had...
Wow.....
John, I feel your pain here, it's like pulling teeth..... Maybe he needs more people asking the same question over and over.
To OP:
How much total budget do you have for EVERYTHING. Not just a receiver (which frankly, based on the equipment you have, won't really be much of a help or...
Of the three brands you have listed, I'd rank them for subs: Epik SVS Klipsch However, I think you'll find the Epik and SVS are on a whole 'nother level compared the the Klipsch. Check out Elemental Designs as well, for good performing, reasonably priced, high output...
There have been some good suggestions here. For the OP, I'd say it comes down to a number of factors, those being: 1- Your Budget 2- Use (Movies/Music/Both - how much?) 3- Your priorities (output, range, tone, extension, depth, tightness) 4- Your space (size matters) 5- Aesthetics...
One option that is also under $400.00 and is automatic setup is the VLSI Anti-Mode 8033B. Available for direct shipping from Finland. It is truly "plug and play," with setup taking approximately 5 to 7 minutes. Made a significant difference in my room. There is a fairly significant thread about...
Check out ATS Acoustics. I got all of mine from there, very fast shipping, no problems, and very reasonably priced. They have a ton of different colors as well. IIRC, it was about $38 bucks for a 2' x 4' x 2" panel.
To the OP, RobertJ appears to be steering you in the right direction. I myself just purchased a new sub and was debating between eD and Epik, and ended up going with an Epik Conquest. There was about a five week wait, but the wait was worth it. I can vouch for the build quality of the Epik...
I'll also suggest an Integra DTC 9.8. One of the highest rated products on the market for what it does. I have one myself, and have no intentions of upgrading, as there really isn't much improvement.
