Reclaimed PA system? These took me all of Sunday afternoon.
A prototype for possibly branching out into sound reinforcement systems.
Made from a surprisingly clean pallet (or pallet edging boards – I’m not entirely sure what they were) and some scrap plywood from some solid old fitted shelves that had been sitting in the garage for years.
Using maths I calculated the optimum port and internal volumes for maximum efficiency and came up with this pair of speakers using Fane and Eminence PA drivers.
UPDATE: Since the photos were taken I added proper speakon connectors and a little more bracing to take the rated wattage, as well as replacing the wood screws with through bolts to make things a bit more secure, I ran them with a 500w PA amp to see how they handled power, they hit painful levels before even stressing the amplifier . . . really want to make a matching sub eventually . . . . They still needs some grills however.

In this case R.A.F. does not stand for the Royal Air Force. . .
