Hi. First post! I have a 4ohm Markbass 4x10. I want to be able to run my amp @ 2 ohms and increase the low end at high volumes. My dealer has a Traynor 4x12 and a Mesa 1x15. Both are on sale at great prices but there isn't an amp at the store right now that can drive a 2ohm load to test with. Any ideas which cab is likely to have lower extension? Thanks.
