Having been asked to do loads of slightly different drawings of a double 12" + Comp I have decided to do a standardised version for public consumption (assuming anybody wants to eat). Although the 12" is from my prefered brand a quick troll thru the specs of other drivers has shown that there are suitable drivers from most of the big players, especially B&C and Faital. Even changed the port position to suit the non-believers :) The 1" is a BMS 4547 on a Faital LTH102 waveguide crossed at 1.4K (as my own boxes) Before anyone asks there will not be a version with a 1.4", 1.5" etc. although there is a version for the 4592/4590 :) We all know that a 1" will not possibly keep up or go low enough to meet the 12's so I look forward to increased replacement diaphragm sales. The drawing is only available as a stp. file and I assume the box builders on the Forum, especially TMAL would love to do you a flat-pack etc. Tony  ------------- www.forteaudio.eu - BMS - db-Mark Processors - Lexon (SAE) |

Very kind of you Tony, I'm sure there will be a few of these built! Which BMS 12" is it designed around? What's the tuning frequency? |
