I haven't used a 4th in 20 years, I just used a low tuned ported or higher tuned to meet SPl goals. @THATpurpleKUSH got me started lookin' at 4ths and playin around. The Sa-15 I was gonna use modeled up nicely with an insane amount of gain where I wanted it. For a single 15 daily use it seems like it turned out even better than I wanted it to... IDK... The Synergy EFA3K powering the thing is at 2 ohm nominal and it's only got a group 75 lead-acid up front at this point but... IDK... windshield is bouncin' nicely up top and I haven't even left the driveway... only about 4 min listening time so far but the peakyness is evident but it still goes fairly low, I gotta get a feel for her before I open her up with those low notes... anyways I'm relocated and it's a quiet neighborhood and I really don't want to cause the neighbors to call the cops.
It's not done yet... amp is just layin' there at this point... but I HAD to hear it. Sub got here this AM after I had to return the 1st one (wrong impedance) and I just got a new one this time instead of tryin' to save a buck on an open box item... duh!
Gotta get me a secondary AGM now and finish her up... but this thing pounds!
Thanks Kush
