Bass modules are now complete.
Textured black Duratex finish on the outside. Bitumen rubber on the inside. 60L sealed box.
These are available now as a flat pack and they are designed to go into a corner on a 45 degree angle.
They are heavy! The MDF in each box would weigh about 20 kg, but the completed boxes once heavily damped weigh in at 43 kg! That makes a very inert box, when knocking on them they have a very solid sound, well damped. Add in 12 kg for the driver and you have 55kg!
