I have an 2008 MarkBass Jeff Berlin 151 combo with a B&C 15in speaker. I like to add another speaker cab, but don't want heavy cause I am 66years old with a hip issue. So have you heard anyone adding just a 110 bass cab to a 15in combo. My Jeff Berlin will put out 500 watts with another cabinet. I though about adding a 250 t0 300 watt 110 ported cab. Know tweeter my combo has know tweeter either. I use to use a SWR 750 head and 210s and a 15 cab. since hip thing I have gone to less weight. Anyway I though this the best place to ask. I even though about using my little Amps BA 110 Put a better speaker 300 watts and fix it so I can unplug the speaker from the Amp and using it for a cab, then when I get done Pug the Amp back up. That way I can use it as a cab then back to a little combo,
