Help Please.

I want to build a ported box for 4 FI 15" BTL's

Currently I have a 9 Cuft box with 2 FI 15" BTL's. Each sub in it's own enclosure. FI suggests 3-5 Cuft per sub.

Can I make just one box for all 4 with one port?

Or do I make a box that seperates all 4 or two? I like the sound with 4.5 Cuft per sub.

I am also lost on the port area if I make one 18 Cuft box for all 4.

Really appreciate your suggestions here.

Thanks,

JR

I have dementia as well after reading your question.

All in one box is fine. Follow Fi's specs and you are golden.

Why??

Heck I have the second Iraggi alt hooked up and have power to spare..so why not? lol

I realized I didn't have all the info possible.

Check this out. These are within FI's specs as to the box volume.

These are my possible demensions. I figured 270 sq inches port area and 18-20 in long(deep)

Not sure if this is right.

Let me know what you think please.

specs box (18 Cuft) (34H x 45W x 20.3deep).

Any suggestion really welcome.

thanks,

JR

Thanks...done..

Not a problem, keep me posted on updates as well.

will do..

I need to video it the way it is now and post it.

I'm also going to see how many DB it produces.

Just heard from BKOLFO4 that my measurements are good to go.
