Box Modification SPL Gains

[mazzasec]

****! I wonder how much I could gain changing out my 16g speaker wire for my subs lol

jake...i cant tell from any pics but do you have a divider in between the subs? and also do you plan on trying different angles besides 45s? and different size angles as well? also have you taped up the subs and counter sunk them? mall possible gains. all of them have gained me in the past

[hunterw]

also taping up the sides of the 45s may help. and different size pvc. i saw a gain from 1.5 to 2in pvc. i think adding the pvc to my box got me almost a full db. and its not even screwed down.

[audioarsonal]

Sorry to see the PVC on the outside didn't gain.Maybe trying larger pieces that have a bigger circumferance won't cause such a lip.Or like was said before cut them in half then cut some off that and so on to lessen the amount of roll.

Going to need a recone anytime soon?

Nah - my subs are in great shape

The coils I'm using actually have me at 0.45 DCR so my 3000s have more power in them with different coils with a lower DCR.

I have a brace with a hole in it between the subs - I was going to try covering the hole later to see what happens.

I will be making the 45s into arcs to test vs. 45s like so :



Taping subs vs. gaskets has always given me exactly the same score unless I am blowing the gaskets out from under the subs - which I am not in this box as the holes are very tight. If I don't use either tape or a gasket I have always seen a loss.

Have not tried counter-sinking them yet.

I may try it again later with different sizes and rolls.

hmmm like a divider like this? or shallower?

[hunterw]

or are you saying you have like a window frame type brace in there?

[RyanM923]

Jacob, are you running 8 gauge to your subs?

Yes he is

Kinda like that - it has a circle hole in it with rounded over edges

I can cover the hole and the divider would be alot like yours.

[sundownz]

Yep, DJ is correct - I am use 8 awg to the subs and then 8 awg to the amps (four conductors total by dB Drag Rules).

[RyanM923]

Yes he is

After getting a .2db gain going from 12 gauge to 8 gauge, I only use 8 now to my subs, and a 12 gauge hookup to the other VC if I'm using a DVC sub. I've never tried running 8 gauge to each VC...
