Get a good 15 inch driver for this nice cabinet. JBL D130 or K130. Original D130 with paper surround are impossible to get, but with cloth surround should be quite easy. If using this outdoors go for a D130F, F for Fender. The D130F was first used in Fender Showman. The F is water resistant.
K130 is almost like D130. D130 has a paper bobin, K has kapton. They both have alnico magnet and will be lighter than the E130.
A D130 in good shape should be able to produce 5 kHz. It will beam badly though. This is not a problem if you play into a microphone.
Save your idea of a 2-way system until you can get a beaten up 4x12 cabinet, or something like the SRX i rebuilt. With that kind of cabinet you can get proper bass as well as have place for a 10 inch driver. Proper bass needs big cabinets.
