Ok quickly here is my current setup:
HTPC for all audio and video, Creative X-Fi 6 channel out
(creative control panel crossover set to 80Hz, +15dB is NOT checked for subwoofer, all speakers set to small, Arcsoft TMT used for blu-ray and DVD playback to decode audio to 6 channel out)
Integra DTR-5.3 receiver 80Wpc 20Hz-20kHz
Paradigm Studio 60 v2 fronts
Paradigm CC-370 center
JBL Control 5 for surrounds
Outlaw Audio LFM-1 Plus
Room is about 14'x14' with 10' ceilings, house is old built in late 1800s lol, floor is carpeted with padding.
Fro the most par the sub has performed marvelously! I am incredibly happy with it except for one damned nagging problem. The main reaosn I bought the sub in the first place... low frequency extension. I never had a sub that did below 35Hz I wanted strong 20Hz with some extension down. One paticular benchmark I use is the movie Pulse at the 1:12:40 mark with the server room as it has a very strong 16-18Hz "pulse" (see this thread for more details
Now typically I have my receiver at about 66 on the volume setting...sometimes I go up a bit more to 76 if more people are there and I am going for that WOW factor (small room so not much needed right now for higher SPL). The problem is with nearly every movie / song I can have the level knob on the outlaw at about 10-11 o'clock (not even half way) and go up to 76 on receiver with no problems...no noticeable distortion, no cabinet noise etc. But on some movies @76 on receiver volume level I have to back the sub level knob back down to about the 8'oclock position and for 66 on the receiver volume level maybe 9'oclock postion.. otherwise I get horrible port chuffing with especially low, low frequency effects for example that part in the movie Pulse mentioned earlier.
The chuffing is worse if I run in max extension mode with one port plugged, it is lessened with max output mode and both ports opened (which is how I have been running it lately) but it is still there (the volume settings mentioned above were for max output mode, if I run max extension I have to turn the sub down even more!)
I Actually went and purchased a nice receiver (AVR-2808CI) so I could then go HDMI direct, then use Audyssey to do a better job configuring things (not to mention get better control and a bit more dynamic power) but after finding a great deal on that receiver, FedEx completely destroyed the unit in shipping so now waiting on a refund and processing and all that before I look for another one. Depressing too because it was $270 shipped and had all lthe remotes, 12 gauge wires for every speaker, monster banana plugs, the mic, manuals..*sigh*
But anyway I was hoping some others might chime in hereand lend some advice. Am I just running this thing too hot? I am tryign to locate a SPL meter now to make sure when I do test tones I am indeed getting the same levels out of each of the speakers. I seen a SPL metere app for the iPad/ iPhone (Ihave both iPad 2 and iPhone 4) and have heard mixed reviews on it.
Last night I watched the new Star trek on Blu-ray again with my new setup @ 66 with sub level set to 10-11o'clock and it was GREAT! But as I said every once in a while I run in to that one low Hz track that I hear the chuffing bad and I am scared to ruin the sub! But having it low like needed for those low Hz tracks takes away from everything else.
So what do you have your LFM-1 Plus set to?
If I can tomorrow night I'll take some pics of the setup I am running for now and post them here.
