What do you think of these light weight cabs?

Weight is a non-issue as far as tone and output are concerned, a well engineered/constructed cab doesn't have to be heavy. Size, however, does place restrictions on how low and how loud you can go. If a lightweight cab is light because it's small then low end output may suffer. As for driver size that in and of itself has little to no bearing on how low or loud a cab may go.

 

avatar hands down, i used to have one and i loved it, only sold it to upgrade to an 810 for more volume in a metal band.

 

First, what is the wattage of your head? If your head is 200w and the cabs total 500 to 1000w then you will not be happy with the sound of any regardless of the make. I use Avatars, never had a problem with them. (2) 2x10, 8ohms @500w each with an Ampeg SVT6 pro (1100) watt head. You need to closly match both. Also check the rating of whatever cabinet your looking at for the lowest Hz it will handle. In Avatars case the speakers will handle down to 36Hz for a good low B. The Ashdowns and GK's are also very good cabs.

 

Have the SB112 -

Would love to add a 2nd for larger venues

It is a great cab.

I haven't owned any of the others though,.....

 

You might consider Dr Bass LLC as well. He has some rather compact stuff that works well. He has what he is calling the RXTreme series going real cheap for the tone quality of what is inside. I would echo Avatar as a viable choice too.

Some cabs just need adequate power to shine. Often you trade away efficiency for something compact. Seeing lightweight amps in the 2KW range makes me think one could get away with that trade these days.

 

The Avatar is the best cab in your list.

 

Have you seen the ABM's in person. They are beautiful, but not lightweight actually I think they are heavy for a 210. But then again I just odered 2 of them.

 

I've never been impressed with single 12" cabinets, but continue my love affair with 2x10 cabinets.
