Nice spoeakers :^)
I like the guitars on the wall. Something i would like to do. So far i only have Doug's Gibson off the Doug & the Slugs album (he even played it on stage)

I've always appreciated Scotts naming conventions - but this one is really unusual! Why 'The Bennite Solution'?
Does anyone have measurements of completed Woden designs? I'm interested in building one but I am worried about the harshness in the vocal region of many full range speakers.
The design of the box mostly affects the LF. Harshness will follow the driver and be fairly independent of the box.

That's generally not where this issues lie with MA drivers. Do you have an example of a driver that is harsh on the vocal region?

I have the moth audio 8" driver and Lii Audio Fast 8". I've heard people complain about the same problems with Cube audio magus 8". Do MA driver's not suffer due to the lack of whizzer?
No. The whizzer isn't for the vocal region, it's for extending the treble region.
The 8" drivers you mentioned probably have a typical rising response, starting at 1-2 kHz, and peaking around 10k.

Here is some measurements of the MA Alpair 10P-A from rutcho:

Should I be worried about beaming? Looks to me like a tweeter is going to be necessary to tame the top end. The woden design silbury looks cool, but a lot of work with little guarantee that it will sound better than a multi-way design.

I have been away for a while and just found this thread. Still working thru it but wanted to express my appreciation. Many thanks to everyone contributing, especially Scott for his wonderful cabinet designs.
Good tp see you back at diyAudio.
Hope all is well?

If you look up the frequency response of various high end multi-way loudspeakers, you will see that they are not that flat either. Set then up in your listening room and the frequency response changes again. The graph from rutcho is not of a finished speaker design, it is raw driver response. The ultimate question is what the final balance is like and if you like that sound. I have a living room that has too many reflections for many loudspeakers, the beaming of large (8"+) fullrange drivers has been a benefit to me. In my home office, with a much better damped acoustic, it wouldn't work for me.
@Scottmoose, a quick question about the Cirrus enclosure. I am experimenting with some composite decking sheets I have left over from a construction project. The pieces are 5.5" (139.7mm) in width.
I can cut them for a thickness range of 18mm - 25.4mm. They are at least the equivalent weight of MDF, maybe even heavier.
Can 139.7mm be substituted for the 154mm width of the enclosure ?.
Regards,
MM

Heavier is not a desired property but sometimes brings extra stiffness which is. MDF is the lowest grade material you can use and is not recommended.
It won’t greatly affect the LF driver, but the low end response/roll-off of the HF nitwill change and the 15 mm (10%) could require an XO change. @Scottmoose

Thanks for the responses. I have some buyout 3" dayton drivers and 3/4" tweeters that I was going to model a small desk top speaker system with. So just as an experiment, I will pull out the DATs and try some measurements with these drivers and the composite decking enclosures. Will use J.Bagby Quarks and Mattp 60 minute dsa's for a guide.
