Caution: very unattractive asthetics but wonderful sounding
Well running REW in my van certainly did a lot for me. I recognized visually what i was hearing, something was wrong with the subs: BLOWN AMP therefore a sub acting as something like a PR with a bit of power to it, making my port a 20" leak in the box. I saw that at my crossover points I had huge dips, phase issues. I also saw that despite having 2000 RMS available up front, 8 very good drivers in sealed enclosures, and a mooin crossover system... my front stage was weak. Matched up with what my ears were telling me.
I sent the amp in for repair and it should be back any day now. I wanted to test my front stage and get it where I want it, that way when i get the subs, I run 2 sweeps...regular and subs 180 degrees, pick the better of the two and be done...well, run sweeps with EQ too.
The front stage situation, I hate mids. In my case the 710Hz-14kHz my FR125S's cover. If I could quadrouple my subs, Extremis, tweets, and power on them all...and leave the FR125S's as are... I'd be a happy camper. My tweets, I had a new build house issue. I started off with 2 2005 Vifas on a KX200.2 thinking the KX amps were 4ohm stable, not 2 ohm. I was getting half the power, and with my wanting tons of 14kHz and up and no 14kHz down, I was getting clipping and break up: bad. I ordered a 2nd pair of Vifas, but since 05' they changed significantly. My 200.2 was running parallel 2ohms now.that helped... but the new tweets were MUCH louder and sounded quiet different. I worked with Madisound extensively after I blew both new tweets. I upgraded to the SX500.2, used it's 36dB/oct slope in conjunction with the PXA-H701's 30dB slope... now I am golden. But after blowing the first 2 I was scared.
Well I stepped up to the plate and turned the FR125Ss back up and the tweets back up, reversed phase on the Extremis, now I am golden!
First some pics of the new mustard! I havent spray painted them yellow yet, but here's the re-rejob:
redid the mic rig:
Set the PC up a little more friendly:
Initial sweep after working volume up slowly for safety
2nd sweep windows up to compare.

PHASE play!
