When looking at earthquakes site I came accross this (15" model):
http://www.earthquakesound.com/supernova15.htm#chart
I was just wondering why it is so expensive ($3400)? It seems to be a 15" driver and a 15" SLAPS radiator powered by a 600 watt digi amp. Am i missing something huge here? The box is 21ish*17ish*17ish. People are selling it on ebay for $1600. That is the MKV-P. Does Earthquake have ridiculous MSRP's?
From prices I have seen on ebay and online retailers raw parts go as low as $200 for the 15" magma and mid $100's for the SLAPS Driver. So even on the high end say 300 and 175 you could make this subwoofer for:
sub and SLAPS: 475
plate amp: 350
materials: 50
at a high end price of 875.
on the low and probably more realistic side:
same order:
200+150=350
+300
+50
total $700.
So the main question is... Am I correct? Would $700 to make a supernova 15" be a good move (not that I want to) or for $700 could you make a sub that would kill this earthquake setup? Also, is it the same Magma driver used in car audio?
Thanks!

I for shoure, would used my money on this instead: http://www.svsound.com/products-sub-box-ultra2.cfm
I'd say 2 of the dayton 12" reference series woofers with a 1k watt plate amp would do nicely...
Your neighbors would probobly try and murder you tho

so you think these 12's (svs and Dayton) would get louder than 2 15's? really?
here is the T/S of the Magma 15"
1500 Watts Max
FS=26Hz
Qms = 3.5313
Qes = 0.4603
Qts = 0.4072
VAS = 7.5Ft3
Xmax = 22
peak to peak= 3"
85dB 1W/1M
Revc = 6.78
Levc = 6.3mH @ (1 kHz)

Sorry dude, i thought you were only using 1 15 incher...
In that case go for the 15s but i personally seem to think the daytons would have really low distortion and sound really good...esp 2 of em...
To beat the Magna I would use two Acoustic Elegance AV15s.

yeah, those do look good, and are a great price! I dont want to build it, just start a good discussion and see how those subs compete with other DIY projects.
