Designed by Troels Gravesen in Denmark.
http://www.troelsgravesen.dk/DTQWT-12.htm95dB, 8 ohms, full range, passive crossover, horn loaded 3 way
Drivers:
Audax 1.2" silk dome tweeter with wave guide
Custom uncoated paper midrange designed by Gravesen, made by SEAS with foam surround
Eminence Deltalite 2512 woofers (2 per speaker, on rear baffle)
The bass drivers will fit in my previous E-Lips OB baffle as will the upper drivers, using an active crossover.
I bought the kit from Jantzen about 2 months ago, with the crossover parts, tweeter and midrange drivers. I procrastinated on buying the woofers, but after Axpona I got psyched up to get started. The Eminence drivers I had sitting in my partsexpress cart were gone. A huge 85% price increase when I tried to put them back in. Neodymium magnets and copper coils are skyrocketing. Same price hike at USspeakers.com. Google shopping found plenty of them still marked at the old price.
I might buy 4 of the 10" and 2 of the 15" while I still can, for future iterations of this design.
Now I need to pick up the plywood and draw a cutting plan.
I'm really looking forward to hearing these. There is a smaller version with 10" bass drivers which a couple dozen people have built and commented favorably on the sound. Only one other guy in Italy has built these big ones. But what can I say, I like big bass and I cannot lie.
Not sure about how to finish them. Veneer would be nice, but I don't think I want to sink another $500 into it. These boxes are huge 1' x 2' x 5'. So I will probably use contact paper or paint. Dunno yet.
I bought my Manley 300Bs 2 years ago destined for these Troels speakers. Finally getting around to it. Can I do it in one month?
