I have a 5.1 setup consisting of two front speakers, a center speaker, two surround speakers, a subwoofer, and an Amplifier. Here are the Model #s:Front: Polk RTI A7Center: CSI A4Surround: RTI4Sub: VDR-12I'm not exactly sure what the knob on the back of the subwoofer does, but it's halfway between Direct and 80 Hz. If I turn it more to the right then the Sub goes to 80 Hz.. If I turn it more to the right of that, it reaches 40 Hz. Any idea where that knob is supposed to be? The Auto On/Off switch is also set to Active.I also went into the Auto MCACC in my Pioneer VSX 9130TXH. It ran through the setup but it determined I didn't have a Subwoofer, despite that it's plugged in and connected properly. I did some investigating on Google and realized that it's not working because the Center and the Front Speakers have been set to Large. Are these models considered "Large"? I could get sound from my Subwoofer if I set them to "Small" but I sort of feel like I'd be losing sound quality doing that...Last question. I went into the Manual MCACC and there are a few options I'd like to ask if it would be better if they were turned on. One of them is called X-Curve which is currently set to off. Another in the THX Settings is called Loudness Plug. That's also set to "Off". The X. Over is also set to 80 Hz so I'm not sure if I need to do anything with that...Some help would be much appreciated.

Set all speakers to Small. This will activate the subwoofer better.


Set the knob on the sub to Direct. This lets the receiver do the bass management and crossover. 80 hz is fine.


X-Curve is an option. You can use it to reduce the hgh frequencies (treble)  little if your speakers sound too bright.


I don't know anything at Loudness Plus but again, it's an option. Use it if you like it. If not, leave it of..

"Everyday room": Panasonic 58" Plasma, Dish HD DVR, Pioneer Elite vsx-23, BDP-23 BR, dv58avi universal dvd player, Paradigm Studio 20 V1, CC-450, Dayton HSU-10 subwoofer.

"Movie/Music room": Toshiba 65" DLP, Dish HD receiver, Marantz 7005, CC-4003, BD-7006, Polk LSI25's-LSi7's-LSiC, 2 original Dayton 10" "Mighty-Mites" subwoofers. (subject to change without notice).
Also have  MB Quart Vera VS05 +.....too much to list. Help me.

Those "Small" speakers are quite big. The MCACC even set those speakers to "Large"... Even the center speaker. I'm not going to lose any sound quality by leaving them at "Small" am I..?

Large/small is nothing more than...Included in bass management = small.Excluded from bass management = large.Otherwise, follow Gene's guidance.
