Hi, Johnny,
Thanks, ace. Got mixed up for a moment there. I knew your cabinets were 12's, but confused them with the 410 "V" cabs that were on eBay.
I have the accessory horns, although each one has only two input jacks on the rear, not three as the literature states. Am I missing something? The cabinets are as well made as any Sunn gear, and the horns are metal and not the plastic used in the 1505 cabinets I have.
I'm familiar with the Sunn radial horns, too. My first Sunn PA was the original Coliseum with the 215 bottoms and JBL Reflectors. My later Coliseum had a 16-channel Sunn board, four Sunn 15 bins and two Sunn large radial horns. Several Col and Con slaves drove everything, and the monitors were a combination four of those V-style laydowns -- maybe two 12's in one type and a 12 and small horn in the other. Too long ago to remember.
I'd love to find a pair of those 412SR columns at a reasonable fix-em-up price. They'd be very nice, I'm sure.
Thanks again and warmest regards,
