im just wondering if i shud rush build it,just for spl comp,or not...

its on Feb 8th,i can buy the woofer off the guy im borrowing off if i want it afterwards too! i jsut need to find 250watts!

you can estimate
105db eff
20db amp
13db car gain
=138db.....

my car booms at 50-55hz by about 7db relative to 80hz,so i thought id load the cone there and burp it around that freq as to save the woofer from moving too far and BL compression? also im unsure of exact xmax so this helps too.

Im estimating im ~8db down from expected and hoped performance with current 8" with 25watt rms Pe and 3.5mm xmax!

Cheers!

Cheers!

The driver handles 10x more power, hmm? That should put it at about 5-7dB louder.
Maybe more,as the 9$ woofer was ultimate cheap no brand..
Also this horn models slightly higher efficiency...

I'll bet you've already done the Hornresp simulation
its allready CADed up! the moment i saw those DDs, i thoht id give them a try! Wgeiger apparently used some 18"s ,or was going to..of theirs. High BL high mass beasties, like big lab12s
