Hi everyone,
I've published a new loudspeaker design called "Revelation Two - M4 WG".
It uses the ScanSpeak Revelator 15W/4531-G00 mid-woofer and the Classic D2905/9500 tweeter paired with the Visaton WG148R waveguide.
It turned out to be a really nice combination. It has a LR2 cross-over topology and the cross-over point is 2.2kHz
For further details see: Revelation Two - M4 WG

This is great. Any thoughts on using a cheaper tweeter from seas, from the following link this looks very promising

Hi,
Not in this design, but the SEAS H1189 also works very well with this waveguide. Perhaps I will in the future do a SEAS design with this concept as well.

There is no measured electrical or acoustical difference between the two cross-overs, but some claim that a symmetrical cross-over sounds better because of the presumed easier load for the amplifier.
Yes I've tried it, but I stand neutral in this topic and I say it's amplifier dependent if you notice any difference.
I gave it as an option because I thought it could be a nice touch for anyone to test and experiment with. This cross-over was suitable because it wasn't so complex and didn't require too much additional cross-over components.
Here is a commercial loudspeaker company using Symmetrically Balanced Cross-overs. Gauder Akustik

Hi,
I'm not sure I fully understand your question?
Since, I used a flat baffle enclosure from Dayton Audio for the Revelation Two - M4 WG you need to tilt the enclosure backwards by ~2 degrees in order to get a perfect phase integration between the drivers.
You can also turn it upside down and have the mid-woofer at listening height or even better make a custom built enclosure with a 2 degree sloping baffle.

Hi Göran,
I think I'm just convincing myself not to build these he he.
I have heard the SS woofer in many different designs but only on a flat baffle and I guess high order and/or assymetrical crossovers.
They have had some great mids and incredible deep bass for a given volume, but none of them have been as coherent as I would like them to be. Low order crossovers with time aligned drivers are pretty addictive if you are lucky enough to hear it in a well implemented system.
I might just set off for your new design!

As I said in my other post, this particular driver has a unique split personality. It's a bit lush and warm on the mid and lower mid but as it moves to higher frequency it's a bit elevated so it may sound warm below and bright up top, so as you said, it may appear to have integration issue. I have worked with this driver before, so what I do is instead of trying to integrate the design, I learn to integrate my hearing and enjoy its midrange.
