I'm going to build another 210 cab and to finance my project I need to clear out some stuff. I have two used Eminence Basslite C2515 neos for sale. They are in excellent shape. If you're thinking of building a small, lightweight 115 or 215 cab, these are great for that mid hump, "cut through the mix" tone. I've had them in 115 cabs that weighed only 28 lbs. each and they packed a punch. Great speakers, but I'm going all 210 now. I'll sell both together for $150 plus shipping.
