I thought I would announce my latest non-vaporware project. My friend thought the baffles look like tombstones, hence the name. This is a dipole midrange design with a monopole woofer section to load close to the floor to come closer to power matching the radiation patterns of a dipole to monopole transition. I chose this layout because it sounded great when I heard a similar design at RMAF last year, and because I simply want to try it. No need for fancy EQ, and there's no need to let me know the limitations of not using dipole bass. I fully understand that.
The woofer is the Seas W26.
The midranges are the Seas W15CYs.
The tweeter is the hybrid H1212 waveguide loaded DXT tweeter I tested awhile back.
I took the 2 best profiles from above and merged them, so I can easily compare the differences. Below you can see the stock 27tbfc-g tweeter and the DXT dome unit on a 27tbfc-g motor. I labeled each set of harmonic distortion for the DXT dome unit on a 27tbfc-g motor as "DXT". The DXT hybrid outperforms the stock 27tbfc-g tweeter in all non-linear distortion tests except D2. With the benefits of a waveguide it will be even better.
This speaker is intended to be my reference design. I don't think the drivers get much better in terms of overall quality, etc.
Here's what I was able to put together this weekend. They will be finished in a beautiful Curly Cherry veneer.
