Wel, I finally got my SB audigy 2ZS notebook card calibrated, checked levels, and made some preliminary measurements. These are attached along with a crude drawing of the room setup.
My setup is as follows. I have a lexicon MC1 MC1 processor feeding the sub output with an unbalanced cable and a RShack RCA to 1/4" plug adaptor to a BFD 1124 with Y-connectors splitting the sub out put signal to each of my 3 subs. Two of them ( one in each front corner of my 15'W x 35' long x 8' high room) are Rythnik audio 12" 350 watt servo kits in 2 cuft boxes. The third sub is a TC sounds 18" LMS 5400 with 2 Passive 18" radiators in a box slightly under 7 cuft. The VC's on the LMS5400 are wired inn series to a bridged QSC 4050HD power amp. I turned off the amps to all the mains to take my first 2s. measurement. The next one was done with the LMS 5400 only, which is sitting in the front left corner.

I have soom questions. What is the best sequence in whic to run REW? One sub at a time? All three together? The two Rythmiks at one time? Should I stack them together? Wher best to set the level controls and phase adjust ment on the LMS5400, since there are really not contols on the sub or amp, should i use the BFD filter. I cant currently use the lexicons output separately since it only has one sub output. I could use an ART cleanbox; I have one and also the caps recommended in the cleanbox mod article , but have not yet done the mod. Also, I don't have any high pass filter built into the system for the LMS5400, can I somehow use the BFD for this? What about using the Rhythmiks for midbass and the LMS5400 for the really low end, even though it seems to have really good extension. Thanks in advance for any advice with this.
