Speaker Box and Add. Speaker Suggestions

[middleman]

I built a sealed box using this speaker

Kustom
Model: SRO15
Cast Aluminum Frame
3" Edge Wound Copper Voice Coil
8 Ohm 80 Oz. Magnet
200 W. Continuous

I have two questions:

1.) Anyone have any info on the interior volume that the box should be for this speaker. I can give you the depth of the speaker if you need it. I have already checked in the WinISD Beta program and could not find this speaker in the list?

2.) I'm running a Shuttle 6.0 so i figured that I would add another box to it and run it at 4 ohms. Any suggestions for which type of speaker to use, I think I want to add a 12. I'm not looking to sink a ton of money but I would like to check out my options. I have also checked out Bill Fitzmaurice's page and those cabinets are quite wild looking.

This is more like a prototype but it is functional, close enough for jazz. The interior dimensions are 22.5 (l to r) x 20.5 (top to bot.) x 14.25 (f to r)

Any help would be great!

but youve already built the cabinet............

Yes, I realize this but I built it before I knew about box tuning and all the techinical stuff. So now I am wondering how close this is to being at its peak performance. If it is way off I can always pull the speaker and build another box for it. I built the box for fun as a summer project.

Depending on the vintage it may be an EV SRO, thought that same title was applied to first generation EVMs as well. In either case I wouldn't invest in a cabinet for it, as there are many twelves available now that will seriously outperform it in a smaller cabinet size at half the net weight.
