I've been looking into different one 12" cabinets. Aguilar has one that is tweeter-less and one with a tweeter. What is better for double bass, tweeter or no tweeter?
I was using a GS112 (w/tweeter) for double bass for a while. While I thought the Aguilar tweeter sounds terrible with double bass, it came in useful once in a while. 80% of the time I kept it turned off but there were times where I needed that extra "zing" to cut through so I would turn it up about 1/4 of the way.
Its really all depends on what pickup you are using also. But, in my opinion, its better to have it and be able to turn it off rather than not have it all.
Just an FYI, if you are looking to Aguilar 1x12s.. They are great cabs BUT I could never get the sound I wanted out of it for upright. Electric was a different story. They always had a great sound for electric. But, the mid scoop that GS112's are known for didnt work out well for upright. They could be quite boomy and twangy but lack mid definition. Also, on the tweeter issue, I always found that the sub and the tweeter SOUND like to separate speakers. With my Epi UL-110s, the sub and tweeter sound like one speaker. Much smoother transition between the two.
