Please, tell me all the thing you now about this speaker. I've got now a ampeg cab with a 15" speaker and a ampeg cab svt-s10he. I want to change the 210he with the 410 he, but everyone in this forum, tell that this is a bed cab...I want to use a 410hlf, that have more extended frequency range, but is 4ohm, and I can use this cabinet all alone, and not with my 8ohm 15" cab. So, I think a 6x10"hlf speaker can substitute a 1x 15" + 4x 10"he cab. is better: ampeg svt-610hlf ampeg svt-410hlf ampeg svt-15he + svt410he I like deep bass, but i like to have a lot of punch in the sound. the heads I like to use is the svt4 pro and the svt2 pro. Tell me all the suggest and thing you think about those alternatives of cabinets combinations.
