Thanks for posting the pictures Rick.  They look very nice.  What are the two woods and what finish did you use?  Is there an acoustic reason for the tapered cabinet?

Tineo veneer with Wenge trim and a clear finish. In theory there are some acoustical advantages for the interior reflections of the cabinet as well as reduced edge diffraction for the exterior.

I know this was asked before, but now that they are complete, any initial impressions on how this design compares with the SSR?

Also, were this to be converted to a WWMTM, any speculation on differences between this and the RC5?

I'll have the Garnet and Galena at the RMAF which will be a good comparison since the upper section of the Galena is very similar in design to the SSR. A WWMTM version of the Garnet is in the works but without hearing it I would hesitate to speculate on a comparison with the RC5.

Hello Rick. Did you get the email I sent you last night? I would really like to get the ball rolling on those speakers we talked about.

Yes - I emailed back to you earlier this evening. Let me know if you don't receive it.
Nope. I haven't received it yet. I checked my settings and my spam filter seems to be off. If you could send it again, hopefully it will go through this time.

The Scan-Speak 8" is an exceptional driver. We just completed a project using it for Paul Kittinger in a MLTL design (Paul assisted with the Salk Song Tower TL cabinet engineering) and Paul is raving about the results  :thumb:

 Yep I listened to them. I had my 4 year old with me so I can't give a detailed report, but I will say I really liked them. They have a very clean sound and for a stand mounted speaker I thought they sounded like a larger speaker.  :drool:

I'd love to hear more about this design. When you're ready to reveal more information, I'm all ears.

Paul is a perfectionist and his cabinets reflect that. I also did the design for the Seas MTM pictured below the Cantilena and it received good feedback as well.

Hello Rick, I have a couple of questions about this design. You wrote earlier that the SSR would have more bass than this design yet the specs on your web site would appear to indicate minimal difference. Could you elaborate ?
The vertical response graph on your website seems to indicate this design could be used on stands that put the upper woofer at ear height rather than having taller stands to put the tweeter at ear height. Is this a reasonable conclusion ?
This design looks a bit like it is really to be used with extra  woofers?  Could you comment on the pros and cons of this design relative to the SSR ( other than cost ) as a stand alone speaker ?
Thanks Mike Anderson

Yes, it turned out that the bass extension between the two was not as different as I had anticipated. The Accuton driver has a pretty low Fs for that size of a woofer; in fact, lower than many 6.5"-7" woofers.

Even though the coverage is very smooth on the upper midbass axis I still reccommend keeping the tweeter at ear level for the best soundstage. Extra woofers are certainly possible if you want to increase the bass extension, additional dynamics, and the other advantages of a 3-way. 

The presentation is different between the SSR and Garnet due to the MT versus MTM format. MTM's tend to be more focused with less reverberant sound from floor and ceiling reflections. The Accuton drivers are also very revealing so the Garnet is less forgiving of bad source material. The load is 4 ohms for the Garnet versus 7 ohms for the SSR with the Garnet's sensitivity being 88db versus 84db for the SSR.
