in process....
After projects and measurements with WG148R and WG300 it was time to come with custom made waveguides, offering better match and results with various tweeters.
I decided to focus and design the waveguide with the throat diameter allowing to mate various Scan Speak tweeters, as quite a lot of them could offer good response and are available in various designs and prices. It is possible to mount ring radiators or domes.
I decided to start with D3004/6600.
The first prototype was CNC machined with some error so WG profile is not exactly what it should be. Anyway, measured performance is very satisfactory, especially area below 6kHz.
LR4 crossover was modelled and created and there are listening tests in progress, showing it is very worthwhile working on this project further.
SS6600 + WG waterfall
This is really nice, there is nothing that would indicate any problem with SS6600 combined with WG.
MW19P waterfall
LR2 is not really feasible here, as was expected.
FR horizontal, 0-90deg, 1m
Polar map, horizontal
New WG to be measured soon......
After very good listening experiences and feedback from listeners, this projects got bass module with 28W/4878T01 woofer. The first measurements and crossover modelling look really good. This project still uses prototype cabinets with not optimal WG profile and new waveguides should improve 10kHz area. Anyway, except small MW19P resonance at 1200Hz, whole frequency response, off-axis responses smoothness and directivity control are what I would expect from good waveguide implementation.
The below situation is for listening distance 2m.
Normalized horizontal off-axis responses.
28W horizontal off-axis responses, measured from 1m GPM in room. Impulse window 9ms.
