I've been doing a lot of research on this. I do a lot of local gigs and get to them on the bus. I had a Markbass CMD 121P which was great but the speaker really let it down IMO. If you A/B it with the internal speaker and then an external, the difference is astounding !
I had an EBS HD350 and two Neo cabs which rarely left my home so I decided to sell this rig and get something lightweight with a great sound.
I settled on the Markbass F500 head. I'm still trying cabs but so far I've tried EBS, Schroeder 15+L, Markbass ' yuk ' & Epifani UL112.
The Epifani blew everything away by miles. Super tight low end, clear mids and classy highs. All frequencies are clear and level and it only weighs 30Lbs ! Alex from the Gallery also highly recommends the Markbass/Epifani setup.
I haven't tried the Compact yet and The Berg's are a little to expensive for me at the moment although I hear great things about them.
So basically, check out the Epifani cabs would be my recommendation.
