I play double bass, using a ten2 combo but I'm not so happy with the sound of the ten2 cab. It is fine for lower volume jazz gigs but when I have to turn up for some of the more kicking R&B tunes it is a bit lost. I'm thinking about building a closed 2x10 cab with these same drivers. I've used modelling software with the specs from Eminence and although the ten2 is a closed cab of about 22-25 litres the software is recommending a cab of about 80 litres. I will still be using the ten2 combo's amp. My question: BassBox pro has a setting for high output which reduces the size dramatically. How much will this sacrifice a good bass sound? Has anyone tried doing anything similar and does anyone have any recommendations? Attached are the specs from Eminence for the ten2 drivers.
