LF21N451 HORN

Hellou everybody,...

Iam wanna build couple of bass horn, and i saw a specification of new RFC driver LF 21N451, this piece of sound is yust "must have"... but i didnt found any good looking box design, so,... i started this topic.

Look on this baby: http://www.rcf.it/web/rcf/products/precision-transducers/neodymium-low-frequency-transducers/lf21n451 - http://www.rcf.it/web/rcf/products/precision-transducers/neodymium-low-frequency-transducers/lf21n451

BL over 33 (so punch like chuck norris roundhouse kick)
SPL 98
Qts 0,25
RCF LF21N451

Because i dont want any bassreflex or scooper box, i decide to build a 21' horn! Best will be some kind of box like 1850... but for 21' speaker.

Unfortunately
, there's no plans on net for something like 21 horn. So, i start this post and i waiting for somebody, who can upgarde 1850 horn on 2150 horn, or help me desing other 21 horn.

Thanx for replies,...
