Snell type EII/III

I have a couple of woofers for these speakers. Can anyone tell me how big is the effective box volume of these speakers, and the size (diameter/length) of the port?

Hey,
I have just put a peerless 830884 and the 1" HDS tweeter in these speakers and made my own xover at 2KHz. (-2db tweeter attenuation) I would like to find the box volume. Does anyone know it from a spec?? P.S. they sound great and I would highly recommend it if you have the 830884!

The more accurate I know the volume the more accurately I can correct the port length. As it is, if I assume a 1.4^3 box then the port would need to be 1.8" longer than the original. This is due to the 830884's Thiele Small parameters.

Thanks!

I have an EII in my posession and measured the cab. resonant freq. Fb ~ 32 hz (WT2 meas.). and port size = 5.125 long X 2.875 inch dia.

Using my helmholtz spreadsheet, I calculate a cab volume of about 2.3 cu. ft.
This speaker has a Seas H334 woofer.

Did you put a Seas woofer in there? The original one I pulled out was an old Vifa woofer. Thanks for the cabinet specs.

No, this is the original woofer. My customer is the original owner. It's my understanding Snell varied somewhat between Vifa and Seas 4 ohm woofers.
