Been reading the past few days and just can't decide. I need a bass cab, problem is I haven't used a huge one in a while. ( 4-5 years). My last huge cab was a Mesa PH1000. I would prefer to go with all 10s this time. ( Even though the idea of a 2x15 or 4x15 would be sweet...even have kicked around a 4x12 but the prices are expensive given my budget) I wish I could just go test them side by side, but I can't. I will be running a Carvin B800 but might be bypassing it with a VT Bass preamp. On paper, I like the idea of the 610HLF. Smaller, more lows, etc. However, the reviews are not that favorable here. Perhaps you geezers are just stuck on your sealed 810 sound I kid I like the low end of 15s, so I wonder if the 610 would be nice for me. However, people say the 810 has more punch and cuts in the mix better. I like that the 810 doesn't have a tweeter. I will be playing BEAD and need the cab to handle the B of course. ( worried that the HLF might get farty) I can get a 610 for $399 or an 810e for $449. I have primarily used Mesa cabs in the past but I have nothing against Ampeg, and the price is just too good. I have a budget around 500 bucks and for the money think it would be hard to pass up either one of these.
