Default 32 Identical Fostex Drivers - Vaughn Cabernet II

Here's a a noteworthy design I came across yesterday (at RMAF in Denver), called the Vaughn Cabernet II. Apparently to boost the world economy, it conspicuously consumes a total of 32 Fostex drivers per stereo pair (and that's just for the midrange).

Each speaker has 8 forward-facing drivers, and 8 rear-facing drivers. The web site says 4" drivers but they didn't look like the FE103En to my weary eyes, so I assume they are in fact the 4.5 FE126En. These speakers were in the Wavelength Audio room (and was quite crowded).

The sound was really ear-pleasing. I wonder if they are going for any of the physics of a line array. If so, perhaps it is subtle as it just sounded like a nice, neutral, easy-going design sans flash (as opposed to, say, Don Keele's CBT array which is like getting lost in a freaky forest of sounds coming from everywhere and nowhere at once).

It's always nice to see and hear a flat-out overkill design like this.

I concur.

I disagree gents. Some slightly better closeups here: Speakers

Take a very close look at the frames on those drivers; specifically the corners. If that was the FE126En, those corners would clipped at 45 degrees. Since they're not, it's almost certain to be the FE103En.

And no, I'm not that sad. I just opened up the data sheets out of interest & noticed the detail difference in the frame & compared. OK, that's sad enough I grant you, but at least I didn't know it off-hand. Either way, should be easy enough to DIY.

If I read the "data sheet" correctly, those are passive radiators on the sides. I guess 16 FE103s per side in a bipole arrangement could dig that deep, but I'd be inclined to find other ways to spend $8000 (or a whole lot less) but then to equate low production "retail" to DIY budgets is a bit unfair.

Nice enough job on the enclosures, and considering they were demoed in the Wavelength room, no doubt the total system was very ear pleasing.

By Jove you are right... i was going on the relative proportion of the cone, but when you can see the frame, the proportions do look more like FE103En, I have both on my desk at the moment i'll snap a picture.

One thing those pics also show is that they are bamboo plywood, but it looks like they didn't bother to use the better stuff.

Aha, I stand corrected. Funny how big those drivers seem in the Vaughn.

I guess size is relative as I've been living with the FE83En's, which make everything else seem huge. (Picture is the FE103En's on the left, FE126E's on the right.)

And - they are beautiful.

The side firing woofers - passive?

Not woofers, passive radiators. They don't have a motor. Looks like the 12in Dayton Audio NS310 currently on clearance offer at PartsXpress: Dayton Audio NS310-PR 12" Cast Frame Passive Radiator 295-140

Going by the dimensions on the site, the alignment of 16 103s with two of these PBRs doesn't look so great to me, but YMMV. They're pretty boxes though.

Ah - ok, my bad.

Would this be a good solution for bass extension if properly aligned? Still bettered by a 12" horn, I guess. If the size factor wasn´t always there..

Yes & no. Passive radiators are most commonly used in situations when a vent would be very (perhaps impracticably) long for a given box size, although there are other uses of course. I can't say I've ever used them myself, although I've nothing against them. They have their advantages and disadvantages like everything else.
