Although some would argue that the 610HLF is the legendary small ERRF 8x10 s'arrter so why so close to the ultimate goal! This is not the same concept. In addition to 6x10 inches, there is also a tweeter that can attnuer if necessary and also three ventilation holes that I think are going to look for low frequencies.
RMQ important: it fits in the trunk of a break which is not the case forcment 8x10

SOUNDS

So is the one rvlation! I use it with an ampeg SVT3Pro (it looks like they are made for each other). Power and projection out of the ordinary, the sound is prcis and dynamic. I use a Fender Precision and a Rickenbacker 4001 and I must say that the tweeter becomes important here.
I plug my fender baritone also in and it's perfect

OVERALL OPINION

I use it for 6 months (studio, live) that happiness! Y ame way to carry alone, but must not do is every day. I tried it compared to the 8x10 and the diffrence is impressive. I'm not saying that the 8x10 sounds worse. I would say the 8x10 sounds softer, rounder and the 6x10 is more dynamic
