It's cool to see those Enthraals on the market... I remember watching a few of the vids Javad did on that design... they weren't all there when I watched them, but it was pretty cool.
There are a lot of interesting kits available for a wide range of prices. The best are ones where you get Gold quality from non-premium components. That said, I think there is also something to be said about well designed Speakers built around Premium Drivers: if the Designer is any good, the quality of the Speaker will be fully in the hands of the DIYer where a little competence can yield great results.
An interesting example is the Iluminoso kit from Rick Craig at Selah Audio... he was selling the Kit for $3K, all SB Acoustics Drivers (10 in total) including their Be Tweeter. His cost of selling it as a Speaker was up in the $7-8K range. By all accounts, it would be one of those Speakers that you could keep around for 10+ years, and the quality of the finish would make it a true work of art.
I was tempted to order this... alas, no more with Rick's passing.
Regardless, I expect I'll be building some BMRs in the future as I'd like to add one more to my stable, perhaps bring my rears down from above the closet. I have two unmatched BMRs, so I would buy a single kit and rebuild one of the others into a matching pair.
But for all this talk about Kits... I still want to build one of Troels Gravesen's designs!
