Hi Guys
I am working on a box for 3-12" Volt 3143's and a ATC mid and SS 9700.I seem to not be in agreement with my designer on the box vent(front firing).
The box is 13w x 58h x 23.75d(inside dimensions).My designer says a vent of
4"h x 13w x 8d for a F3 of 34.9hz,Fb of 31hz.
The owner of the speakers was hoping for a little deeper F3,Fb.

Volt 3143

fs-34
Qa 5.7
Qe .37
Qt .35
Vas 76l
xmax 5.2mm

anyone have any experience with these?

A late response:Yes but not when using 3 in parallel that for me is a 'conundrum'= Why? is it necessary to present a 2 Ohm load for the amps.

I have these for my pals speakers
and 4-2500/10" midbass for my new project and 6/ 8" for center and surrounds.
I was thinking on using the 8"(MB,M,T,MB)but not sure they will withstand the sometimes odd lower fs punishment of 40-50hz.But if the 10's donnot image well,then I will try the 8

Yes inductor
I just started 3 projects
JBL Reference in a W,MB,M,T,MB,W with 2-2245 and 2-2118 and one ATC mid and SS 9700 crossed at 160,800,3800 at 12db/
The cabinet is 20w x 26d x 76h inside.He wants a Dunlavy style coffin and the 2245 will fit that bill .

The 3 Volt system(3VS) is under way now although no cabinet tuning is finalized,nor the JBL R.

The 3rd is my personal system and I will be doing some cutting soon.

Projects are on the go..
I have a question as to the 3rd volt positioning.The owner was wondering about placing the 3rd volt at the top of the cabinet in a WWMTW array?I was not sure of the outcome..
Inductor-The JBL are a nightmare to move around,hell the volt one is also.
RD-Bjorn has a link on one of my topics way back for the MB2
