GZRW 30 SPL in bandpass box

So, out with the "old" in with the new! ;)

Bought myself a GZRW 30 SPL, and got a freind of mine to build the box for me.
The box is tuned to 30-50hz, the curve is flat all the way!
4x10" port, soon to be replaced with a 6x20" port.

GZRW 30 SPL powered by DynaBel BF4501 1200w at 1ohm.

Songs:
Flux pavillion - Got to know
Gorilla zoe - juice box

Have you that consolidator for Ground zero ??

[badassdesigns]

@thomasek5 its a 1.5f capacitor wich i use for the mono amp. i'm going to change it out with a battery soon. why do you ask? :) a capacitor is not usefull anyways, and just something that i bought for the looks.

[mrsupervidrater]

ohhh damn thats smart putting the capacitor right there

[DjAndroctonus]

@S4mss 1ohm mate :)

[S4mss]

What ohm your playin? Pretty loud

[DjAndroctonus]

@ivansk1 the magnet is on the sealed part. but as said, these measures is not 100% correct from what i remember. may be a few liters uncorrect. what you could do is to find the specs on the sub, and find someone that make custom boxes and tell them you want 25-55hz tuning on bandpass. that should tell you the correct measures.

i run 1200wrms on this one with a 11x6 port, got an un-official reading on 138.2db on 38hz!

@DjAndroctonus thanks for answer. Is this netto volume (without sub - sub has volume cca 2l)? Where did u put a magnet, in a sealed part or ported part?

[DjAndroctonus]

@ivansk1 to be honest with you, i dont really remember anymore, but i think its 19 liters sealed, and 22 liters ported with a 11x6" (length x diameter) port.

[ivansk1]

Hi

What is box volume, what is the volume of sealed part and what of the ported part?
