Have you heard about these?

Tymphany Linear Array Transducer (LAT)

Driver Highlights: The power of two 12” subwoofers in a sleek tube-shaped transducer only 7” wide.

Note: The nominal impedance of Tymphany LAT is calculated with both coils driven in parallel.

Somebody made something similar to this back in the 70's...Heil?Infinity?

[Ron E]

IMO, about all it has is curiosity factor - you can have something few other people do. If you are the kind of person who gets off on that, it is for you. I doubt that those little 6" woofers have an Xmax of 15mm or so, so it is not going to compete with 12" woofers with that sort of Xmax.

BTW, yes Heil made something like this in the 70's. I think the idea then was to simulate the wave launch off of the AMT speakers, which have since been shown to be rather colored.... Might be interesting to see what someone could do with NdFeB magnets in a new Heil-style diaphragm.

I have difficulty believing what they say it can do.
But could be interesting to see if they work...at all.
( cost is 255 $us each)
The driver are in fact 3.5" and you have 10 of them.
( scanspeak. peerless vifa are part of the same company)
Here what they say:

( there's also the white paper if someone wish to read it):

At approx. 80db/w I sure hope they are planning on some hefty voice coils.....they would need to be able to handle like 1000W to make it to 110db

Now that is an interesting idea. Read the white paper if you haven't.

It does look interesting. 6 cavities in one set, 7 in the other. As the group of 6 is pushing air, the group of 7 is sucking. The difference of 1 is the effective difference. Or am I missing something? The way I see it it is equivalent to a 10" driver with almost no baffle.

2nd look at it - it does appear to have a lot of mounting holes, it could go on a baffle, creating a dipole. Cant help but wonder about cavity effect and air noise. A lot of dead mass to be moved with the interconnecting rods.

yeah the mms on that thing will be HUGE! and to compensate the VC will need to be huge...which raises Le, which makes your midbass sound like poopoo...

but wait dont smaller drivers have "faster" bass?!(toungue in cheek)

no offence but to me this seems like an interesting, but not very practical concept. but maybe im wrong, im not a loudspeaker pro here

The specification on the website reads "effective frequency range 50-300" . Not much sub in that "sub-woofer".

[Geoff H]

It doesn't matter if you talk US$, Can$, or our little ozzie$, 255 of them goes a long way in a 15" or 12" in a sonotube, and that'll do a lot better, with a reasonable footprint.
