Has anybody build Horn or Band-pass enclosure for B&C 12" speakers? I'm interested in 12NW100 project, This speaker has very good parameters, but in B-R box it's not very effective, only 96dBSPL
If anybody has built it-please send some info.
Thanx
Adam

I think I tried some simulations at some point and found it would work in the Punisher horn.  Worth investigating.

allright, but is there any 12"version? I want it to be 12"because of mobility, and limited transport options.

I'm was reading some posts on this forum, and i found that TH-mini is suitable for this speaker, is that right? I have some doubt about TDA's plans, because it's told that for 12" i should make identically cab like for 15", only width has to be 38cm, but i suppose also hole for speaker should be smaller,than what with other diameters?

Yes, the hole for the speaker would have to be cut for a 12" driver if you're using a 12" driver. Otherwise it will fall through the hole.

LOL

I know, i know. Did i foud it properly that it was made in 15mm board? I'm wondering how much it cost, and how difficult to find somebody to cut it for me. I saw somewhere that 12" version weights onlu about 30kG, which is very, very good result, is that true?
