maybe a bit off topic, but do the AI products use the B&C or Eminence drivers? If I wanted a Summa, I assume the ESP15 would be the best alternative, perhaps the same? And if it has the Eminence drivers, would changing them out to B&C drivers require any crossover changes? Thanks

The Ai ESP15 is all B&C. The ESP12 uses an Eminence 12 and B&C Compression Driver.

For all practical purposes the ESP15 and the Summa are identical. You could get them from either Ai in Thailand or me. I don't know which would have the lower shipping costs.

Earl, what is the Eminence model used in the ESP12? Would it be the same one available in your Abbey kit or are you changing that to the B&C 12TBX100?

I havn't decided on the woofer for the Abbey yet, but I am leaning towards the B&C. We were originally having trouble with the 12TBX100 and tried the Eminence, it seemed better. But when we got our first shipment it had the same problem as the 12TBX100. The B&C is the higher performance of the two, but a little more expensive.

Just curious if anyone has tried out these speakers with a low powered SET amp and how it worked out for you. My luck so far with my SET amp has been with little or no crossovers but these look like they may be a step up from the parker audio speakers I am using with my amp.

Just curious. Did you have crossovers designed for your amp?

the parkers have only a cap on the tweeter. Other speakers I tried did not have crossovers specifically designed for my amp. FYI the amp I have is a decware zen select.

Six hours! I use to drive, alone, from Detroit to New Orleans, straight through, 18 hours. Coffee anyone?:bigeyes:

Worst I have ever done is a strait shot from Tacoma, Wa to Santa Clara, Ca ~14 hours after being up all day, then worked outside all day after arriving with no break.
