Got the box together, put the driver in to see how it sounds. Disappointing! Loud as hell, but very bass-heavy to the point of woolly.
But that’s ok, as there is still work to do (aside from making it pretty)
1. The port was bought, and is a cm or two short. I will extend it with something suitable.
2. I will also stick wadding to the inside (I’m sure I can hear a difference).
3. I think some additional bracing would help, too. There’s just about space to put one on the baffle between the driver and port at a 45 degree angle.
4. I also have a bit of tecsound deadening material left over from the studio to stick to the back panel.
I didn’t fancy a normal backplate (why make life easy for myself?) so I recessed the Speakon. Quite like it. The top-mounted handle is a bit big, or the feet I bought for the amp are a bit short. Will have to purchase bigger feet.
