I was clipping horribly, especially from 15Hz-20Hz, I need 2 more HO alts and 4 more batteries
on my last few burps, after bottoming out a few times, it sounded funny. assumed that a coil or 3 or 4 was bent.
the bottom 2 subs are coil-on-top plate... stuck all the way out. Other 2 subs are scratchy... bent formers, unraveling coils.
Had 2 stuck subs and 2 blown subs on the last few burps and "Put ON"!!!
I made a video of candy shop last nite with the top 2 subs, left one is blown but still going, bottom 2 are seazed: coil on top plate... so I disconnected them from the amps. Got all four blue lights, amps are OK.http://www.youtube.com/watch?v=QvOgWxxG87E
"put on" 148.2
LP set to 31.5Hz, HP set to 20Hz... only wanted the low note. clipping is terrible, not bad for needing 2 more HO alts and 4 more batteries!http://www.youtube.com/watch?v=zdbdZFjT9Uo
132.5 15Hz 136.7 17Hz 140.3 18Hz 142.5 19Hz 143.8 20Hz 144.9 21Hz 145.7 22Hz
Terrible clipping, not as bad from 23Hz on up, but 15Hz-22Hz was massive clipping. So now I need 2 more HO alts and 4 more batteries.
4 Fi IB3 18's, 50 cubic feet, 20" diameter port 18" long for a 23Hz tune (more like 55 cubic feet 20Hz tune, but I'll do impedance sweeps later to get exact)http://www.youtube.com/watch?v=Y4QjI1wjej4
147.7 23Hz hair trick unintentionalhttp://www.youtube.com/watch?v=nhVL0cqf79k
My resonant frequancy appeared to be 43Hz and 63Hz, according to the Tem Lab operator...but I think that was just harmonics he was going by. We never got to make a sweep, I wonder if I could get in the 50's up high where it gets real loud.
still in the box, pics taken from inside
