Hey guys, I've got an online buddy who needs to sell some woofers. He's a well known fellow in the audio world but doesn't have the time right now to advertise or sell this due to a move, so I'm doing the advertising for him. It's an 18" TC Sounds unit that he had custom built. 35mm xmax, 20Hz Fo, ~90L Vas, Qt .28, .5" gap and 3.5" long 4" diameter Ti former with flat wound Ti VC. Coil is a custom quad-tapped 8 layer Precision Econowind unit. High inductance - will need EQ. 90lbs so shipping will be a lot. I think he gave me these specs from memory, but they should be close. 9.5L Vd. Let's just call this "The Beast MK-II". Also has a smaller 15" prototype unit, TC-3HP 15" with 3.5" long coil. don't know specs, 50lbs. 5.5L Vd. Dual PR's available for each. Like I said, I am just advertising this for him - once I find an interested buyer, all dealings (payment/shipping/etc) will be done through him. So no one come looking to me for money if anything falls through He's a good guy, and you'll recognize his name once I send the buyer payment info. I can't really post prices on this since it's custom prototype stuff, so let's just say $700 for the 18 and 350 for the 15 ****OR BEST OFFER****. Thanks for reading!
