Woot! B-stock EX arrived today. This thing looks perfect... not a fingerprint on it and only a very slight crack/chip on the back upper corner by the amp. Otherwise perfect....
I have an uphill battle in my 28x30x8 family room. So far it is doing better than I hoped. I have an older AVR so no room EQ of any kind. I would love to hear any pointers or opinions you guys may have to help things out.
SOOO... EX set to Max Output mode. Port plug removed. Crossover defeated.
Panasonic XR55 set to small, 80 and sub only (instead of mains+sub)
I used my older 10" sub to do the sub crawl... think it matters? Corner loaded was the best and the EX is there now. Nearfield behind the sofa was better but could not get past WAF. Oddly enough just left of my TV about a 1/3 way down the wall was 3rd best.
Dialed it in to 75dB on my rat shack analog using the XR's pink noise. Resulted in my XR 'Sub' channel being set at 10 (midrange, 0-20 scale) and the EX just a smidgen past 5. Like 5.2 or so. Any chance this is to much? So far I haven't detected anything 'bad' sound wise. Should I raise the sub channel to back the gain on the EX off?
After a few hours of music and movie clips I started running some sweeps and test tones (at around 65dB because 75 is dam loud) sparingly as to baby it. It looks like I've got some crossover tweaking to do or else I'm just seeing big room gains. 85-75Hz tones are right in line with pink noise from the XR, but at 90-120Hz I read about 5 to 10 dB more than pink noise. In theory the EX shouldn't be playing right? I mean not until it gets to 80... because both the EX and my mains are playing in the 120-80 range.
Also from 70Hz-50Hz I'm seeing gains again at about 5 to 10 dB higher than the pink noise. Also I still detect my mains playing a little bit. I know crossover isn't a wall per say but they seem to be pretty strong down till about 50 which might acount for the +5-10dB I'm seeing above and below cross??? Isn't there some issue with the analog rat shack meters on the lower end as well? Looks like I'm down 3dB at 30 and I'm hearing port noise. At 25 I think I'm just about out of meter but I can still hear/feel a bit of sound although it is almost drowned out by port noise.
I might have an option to put this a bit closer in a near field setup but it has to clear WAF. I plan to use the end table/plexi top to my advantage.
Overall I'm impressed. I've only had budget midbass units before. This is my 1st real sub and I'm shocked that I'm able to get this good of performance in my huge space. Can't wait to get a second....
