Today I received one of my 410 cabinets. The other won't arrive until Monday or Tuesday. My first impression was how tiny this cab is. I don't know how anyone can make one much smaller. I was pleasantly surprised to find plug in casters supplied also. I hooked up to a Kustom Groove 1200, tweaking the EQ as I went. I started out at low volumes, just in case a break in is required. I only worked up to medium volumes today. Very impressed with how "smooth" the horn is - integrating in the overall sound of the cab, unlike the 1st gen Avatars I had which always seemed a little separated from the mains. Lows were clean and solid, mids were dialed in without difficulty. In this short time spent with the cab, I think I'll be set for a long while, especially with 2 of them to go around. In just 3 hours of use, I swear the cab already sounds like it's going lower than when first plugged in. Maybe all in my head...Even after stacking, I think this rig will look more like an mini stack than a full one. Can't wait for #2. I need a big gig.
