I have changed my mind, it IS a book shelf!

 

[gurley123]

I bet it sounds awesome.

Nirvana,

I have the same driver (supravox 215 sig bicone) on an OB. Have you compared the sound of the bib with using it on an OB? Thanks.

i only compare 215 rtf 64 sound on OB (WOW) I want to put my
signature bicone in "caisson RJ "

 

[nirvana]

caisson RJ

OB is great for mid and high freq.
I dont want to miss bass . In BIB, the bass is very good and i
think the caisson RJ will produce good bass too.

i will try soon. picture of caisson RJ (mantra sound )

Jon Giard, are you happy with your'e supravox sign 215 ?

please , send pictures ! Claude

 

[Jon Giard]

Claude,

Thanks for your replies. I like the sound very much. I have them mounted a 12x48in front panel with two hinged wing panels, one 10x48, and the other one 8x48. When I figure out how to post some pictures, I will do it. I'm embarrassed to say the wing panels are only fastened with duct tape. I just have not gotten around to a more permanent arrangement. Looks like your driver is mounted on a removable panel. Do you use this bib for other drivers? Thanks.

Jon

For interest's sake, 1/2 space plot showing the relative differences in LF performance between the drivers assuming the BIB cabinet dimensions refered to above. The 12in AN needs a much larger Vp to 'breath' (as in about 84ft^3)so I imagine that its LF & midband sounded somewhat choked & lacking in transient attack. To a lesser extent, I'd expect something similar from the Supravox, as that high Q also wants a very big pipe (about 45.5ft^3). YMMV of course & there are other factors to consider too. Personally, I'm a big fan of Supravox drivers, even though they generally need very large cabinets.

Scottmoose, please give me dimms for "perfect cabinet" for my
supravox 215 signature bicone.

thank you very much for the graph.spec. What do you think about
supravox TQWT design and the caisson RJ from SUPR. too ?

Scottmoose, please give me dimms for "perfect cabinet" for my supravox 215 signature bicone.

You could do it yourself easily enough via the various spreadsheet dimension calculators here: http://www.zillaspeak.com/bib-howtobuild.asp

As I mentioned, you'd need a very large cabinet of ~45.5Ft^3 (each), making for a box of 67.25in x 28.75in x 40.625in (internal HxWxD). Relatively weak motor + highish Vas = large Vp.

What do you think about supravox TQWT design and the caisson RJ from SUPR. too?

I prefer not to, in the former case. Nothing like enough volume. The latter is a trad. sort of cabinet, but not of a type I personally like all that much.

 

[nirvana]

proposed cabinet

this cabinet is monstrous..... 1285 litre ! More than 5 time bigger my cabinet .
can you show me the results on graph for this cabinet ? Claude

supravox

Scottmoose , please give me the " Z driver" for youre cabinet.
problem with zillaspeak site.

 

[Scottmoose]

It has to be large, with that relatively weak motor & highish Vas. Note that the cabinet for the AN S12 would have to be nearly twice as large again.
