Hi
I would like to know if there is someone with expereience in this field.
I currently have a pair of "working prototype" speakers. They are made from 12 mm plate, wich is rather thin. After assembling the cabinet I cast ~30mm concrete on each side. So the finished cabinet is a rather solid construction.
They are 90 cm tall and 25*20 cm floorstanding loudspeakers, so they are actualy not that big. They are 2-way with vifa d27tg tweeter and a vifa M18wh woofer (6.5").
The cabinet is dead at even loud spl. All who have listened and seen the speakers think they are great (they are veneered with teak). But then i tell them about the concrete they say I'm eccentric, at least.
Never the less I'm thinking of improving the design with the experience made on the 1'st pair. I would also like to hear from anyone with any experience in this sort of teknique before i start.
