Compact transmission line design using a single 6 inch neo driver. It has a forward vent which caters for the lower reflex response and also the termination for the higher quarter wave resonance so that the cone is controlled over a wide frequency range.
This bass guitar speaker is surprisingly loud and deep sounding, especially with a 150 watt amplifier built in (CTL 6+) will hang with a typical drummer at practices no problem and very suitable for Jazz and pop bassists even at smaller gigs or open mics. The speaker is a passive design but we have incorporated an option of sliding in a TC Electronics BAM200 amplifier (or similar nano sized amplifier) in the rear to make the system active for a small increase in depth and weight. The design is capable of controlling speaker movements down to a low B on a 5 string although it is currently optimised for 4 string basses.
Very easy to build using half a sheet of 9mm plywood which offers stiffness and low weight. The folded interior is not difficult to construct and offers additional bracing to all the sides. We finished ours in a red Tolex material and plastic corner pieces and hexagonal metal grille for toughness but the custom finish is your choice!
