The 1st CIAudio Loudspeaker!
« on: 3 Jun 2020, 01:10 am »


Here is a glimpse of the prototype R3 standmount loudspeaker.



This is a 6.5” 2 way (with rear passive radiator).
We use an underhung woofer with an inch of linear stroke and extended response due to it’s low inductance.
The 19mm silk dome is stiffer and lighter than typical 1” domes and has smooth extended response to 27k.
A custom waveguide machined into the 18 layer baltic birch baffle yields ultra low distortion and exceptional off axis response.
The result is a small speaker with ultra wide frequency response, rich & textured midrange, superb 3D imaging, and lifelike dynamics.
With solid bass into the low 30’s, this speaker sounds big and full like a much larger floorstander.

I’ll post more as the development progresses.

Interesting.  Active version coming too?

Reminds me of the Buchardt S400.  Hopefully will be even better.

What made you think about designing/building speakers?  Are you working with anyone on the design?

He's very involved in building speakers for someone.

no plans for an active standmount at the moment. If I did, it would be a nearfield monitor for the pro audio industry.

I do have a reference floorstander design with Ncore bass amplifiers and adjustable F3.
These will be next.

I’ve built speakers for over 45 years and OEM for other companies. For example the current line of LSA was designed by Dan Wiggins and myself.

Many have heard my prototypes at various shows.

The Buchardt looks similar... in fact it appears to use the same passive radiator and tweeter dome.
Maybe they’ve been spying on me as i’ve used waveguide designs for years.

Although similar in appearance, R3 will have much more linear stroke and bass extension.

Below is a prototype from the Newport show in 2015

Very cool.  Can't wait for details about them.  Will you publish polar plots or send to ASR for measurements?

I’m sure we’ll publish measurements but conventional methods mean pretty much nothing.
Measuring at 1m on the tweeter axis tell you very little about it’s performance. I’m much more focused on off axis performance, which is what we actually listen to.

Our speakers will sell based on their realistic sound, not numbers and graphs.

Congratulations Dusty!

Speakers are looking good!  :D

Have you heard the Buchardt?
I would expect it sounds very good. They seem to understand the many things a proper waveguide can do.
This type of design can easily create a big 3D soundscape when done properly. Looks like all SB Acoustics drivers and good engineering at an affordable price.
I’d like to hear them!

I had them in my house next to my M2's.   :thumb:

What do you think about integrating subs with the R3s? I'm very eager to hear more about them, particularly if the imaging could be that nice...

The R3 has strong bass performance down to around 30hz, so subs are not needed unless you need higher volume levels in a larger room.
Subs could be used, but always introduce other issues as you also need to filter low frequencies from the R3 with an active or passive filter.

The R3 is still being refined, but I can tell you the imaging is as good as anything you’ve ever heard 😉
