I am not and expert in wood construction, all the building we do around here is brick and mortar, but, If you get the Horn wall close to the roof you could fill that space up with that spray expanding foam. The side of the Mid bass horn will be sti...

I was there and heard it a while and then came back the next day to see if what I heard was true... it was.I talked with Allen Sides who was there showing his speakers and having a good time. It is a 3 way speaker, It has a 1" JBL compression driver...

I think hearing loss has to do a little bit with excessive HF in todays loudspeakers, with age this is the freq. that is mainly lost, so boosting it a little bit helps that... Most commercial systems exagerate HF mainly to make you think they have...

This is very interesting, I was thinking of such an option given the existence of a basement, (I do not have that luxury, but I have a concrete slab).
The idea that the driver is actually closer to the...

This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensi...
