Man, this thing is a little larger than I had anticipated, but it's already settling in well at the front of my 1750 cubic ft lounge (at least that's what I'm trying to convince my wife!).
I've just run MCCAC (Pioneer LX-85) and it set the cross over to 150Hz... so I ignored that and put it to 80, and the rest of my speakers to SMALL (Castle Trent II bookshelf fronts (70Hz-22Khz), a Wharfedale Pacific EVO II centre, and no-name Aiwa's which came with my wife's all-in-one stereo a decade ago for surrounds).
So far, sounds very nice in music - no chance to run a movie yet until the kids are in bed - but some good tweaking to do, methinks. Before I break out REW and a microphone this weekend, a couple of quick questions:
1) MCCAC set the sub to -11.0db... is this OK, or should I lower the sub's volume (it's currently set to -10db)?
2) I'm currently using a single cable from my AVR, into a y-cable splitter, so that both of the SB13's line inputs are plugged. Worthwhile or not?
Looking forward to listening to this beast a lot more!
Provided the Pioneer AVR sub channel level is not bottomed out, the current settings of -10 SVS gain and -11 Pioneer sub channel level is fine.
A Y-splitter doubles the input voltage and increases the subwoofer playback level by 6 dB (via internal voltage summer circuit), as compared to a single RCA input. When MCACC is run, the Pio will compensate for this of course. So there is no real performance benefit to running a Y splitter - it doesn't add subwoofer power or max output.
The only real benefit to a Y splitter is that it will wake-up the subwoofer from standby more easily, thus helping to avoid on/standby cycling at low playback levels when listening to source material with extended periods of little/no bass content. With that said, the auto-on sensitivity is quite good in the Sledge STA-1000D, so on/standby cycling is generally not a problem/issue with owners, even at low playback levels using a single RCA input.
