Here are the drivers for a new 3-way, the Dettaglio. SB Acoustics Satori 9.5" woofer. Accuton C168 midrange, and Bliesma T25B beryllium tweeter.

Interesting and exciting combination. Floorstanders or large standmounts?

wow nice design. driver selection and the two cabinets per speaker seems pretty uncompromising and for serious business audiophiles

Oh! I didn’t make the connection to these cabinets. I’ll wager these are going to sound wonderful.

Hi Rick,

I believe I saw in a different post that the bass bin utilizes two passive radiators. Would you mind sharing your thoughts with your approach?
Did you consider using two WO24-8?

Before starting on the design the owner had specified an overall height. I looked at different woofer / tuning combinations that would have reasonable cabinet sizes and good bass extension. Only one woofer would be used due to the cabinet volume and the passive radiators allowed a lower tuning. A port of the required length would have too much noise.

Thank you so much for the detailed reply. It is much appreciated!

In the spirit of that aesthetic, cutting the MT-section baffle's front veneer from the same piece of veneer as the W-section for an exact match might be worth a bit of extra scrap/waste?

These were switched. I'll post the matching veneer set later.

Rick, if you don't mind, I'd love to hear more about the covering shown. Laminate, synth veneer? I'm a sucker for unusual finishes.

It's Walnut Burl veneer - the real thing.

I notice a lot more passive radiators in your designs.. customer request or are more good ones available so you're taking advantage?

I like the look. Sort of reminds me of the old Sequerra Metronome 7s docked on top of the woofer. I owned the 7s many moons ago but never got around to get the woofer or the super tweeter.

It's really just a matter of what's needed for the design. Passive radiators are helpful when the box is smaller and needs a lower tuning. In these instances a port isn't practical due to the length required.
