Gig report: I did indeed play through the 410 HLF, didn't have time to load in and swap cabs, as predicted. It was ... okay, but kind of boomy and undefined, just as you guys predicted. Thanks lowend1 and DMN for the input!
It's funny. I'm wondering if there's something inherent to the geometry of 410 cabs that I just don't like. I have literally never played through one that made me want to buy it. I have played through cabs of just about every other configuration that I've liked for one reason or another ... fifteens, twelves, 2x10, 6x10, 8x10, even eighteens... and some odd ducks like the SWR Triad or the (once ridiculously hyped) Schroeder 1210. I don't know why it is... Even a pretty tight 4x10 like the Epifani sounds boomy to me, and they only get worse from there. I'd be very curious to try a sealed one like the HE for sure, it would be interesting to find an exception to the rule.
