The kit, enabled Alpair drivers, shipping and taxes came to $750.00 USD. Shipping amounted to $75.00. The flatpacks are $290.00 and the drivers $290.00. I paid ten percent less for the drivers as I ordered them at the same time as the flatpacks.
I have never heard these speakers, but have purchased them after extensive research on the web, (Planet 10's site and diyAudio.com, builder reviews etc.). I listen to most types of music with the exception of country. From what I have read the Alpair driver will produce "substantially" more bass than the Fostex 126(en) driver, however at the cost of some efficiency. The Fostex driver has also been described as more "shouty??" than the Alpair driver. Further, the Alpairs don't seem to be as demanding as far as being corner loaded.
I claim no golden ear, but I will post my impressions of the speakers once I have allowed for a couple of hundred hours for break-in time.

If at first, the idea is not absurd, then there is no hope for it.
