Scan Speak 25w/8565.01 10" bass driver

[wirewiggler]

I have 4 of these drivers for sale, low hours they are mounted in cabinets that are a design by Lynn Olsen, here is a link The Ariel and the ME2
Scroll up to good base.

I am asking $100 each + freight and 4% PayPal. I will throw in the cabinets but it will have to be local pickup.

We have traveled the same path. I have 4 already. That is an exceptional offer.

They are good drivers and cabinets, I could never get the tuning with my speakers to work out. A shame I have a interested buyer for the drivers without the cabinets. The cabinet construction was as Lynn recomended 3/4 Baltic burch , 4 braces Swiss cheesed, one side dampened. Quite a bit of time though I could have done better on the finish.

I have a pair that I am using in an identical application. I had the same issue getting them to integrate. They always ended up sounding boomy and a bit of that "one note" bass syndrome. I ended up moving them into sealed boxes last year. I know I lost a lot of bass extension, but the tuning became easy. With a bit of bass boost down around 25 hz, they do a great job.

Dave,
My problem exactly what did you end up with for a box ? May go that route as no buyers have panned out.

I don't know off hand. I could measure this weekend when I am home. I just used the factory specs and did a calculation for a sealed box. I uses a .707 Q and moved on. In fact I was able to cut down my ported boxes to about 1/2 the size for the sealed box. It only cost me my time and the price of glue.

I found that the heavy cone of that driver just didn't have the control I was looking for with the soft air spring of a vented enclosure. The tight spring of the sealed box made it very musical, though lacking the ultimate bass extension. What I found strange is that for years ProAc used that same driver in a very small vented sub. I'm not sure how they did it, but it was very nice. I borrowed one from my local shop for a while before buying the ScanSpeaks to build my own.

I can't believe nobody is snapping those up at that price. They just need the right box. I am now considering building them into a 3 way with a ribbon, 4" mid and 10" sealed sub. With a well designed crossover, it would be truly world class.
