1 10course 4 months ago I like my Alnico 4 x10 Super Reverb RI for TVJ & Gretsch Filtertrons, Supertrons, 58 RI PAFs. ----but not anything single coil..........Anyway, I designed and built a 2 x10 enclosure with a proper 2 ohm speaker load (ceramic customs from Warehouse Speakers), and used blonde tolex and wheat grill. It's half the size of a Super!---fits in small cars! Everyone I have shown loves it and says I should manufacture them as a side business. However, Gretsch players tend to like the Bassman over the Super......Can't really use Alnico for 10" spks @ 2 ohms---not that I'm aware of anyway. Total height is 18" or 18.5" as an option just in case 12" spkrs are desired. ----you can squeeze 2 x 12s in a 18.5" enclosure, but not an 18". So, it's an option. Is there a demand for 2 x 10 mini-Supers?
