No opinion on the new driver except that the 3 much smaller SOLs i heard were really good.

Yes i still do phase plugs for FE20x.

Hey Dave,

Would these work in the Dallas 2 horn? I'd love to put them into a pair of Vulcan enclosures but they'll be going into a fairly small room so unless they'd work in a room like that I'm looking at putting them in a single horn. It looks like they'd *just* fit.

I’d expect so.

I hope the quick selling of these limited editiond means more limited editiond to come :^)

Default Vulcan and the FE208-sol

I got the second to last pair. In case this would be useful to anyone, I asked Scott about using the FE208-SOL in the Vulcan enclosures. This was his helpful reply:

Hello Joshua,

As it happens you're the second person to ask this in a few days. Short
answer is yes, acoustically speaking they should go straight into
Vulcan, although I'd shift the rear panel of the low-pass chamber back
slightly to compensate for the volume taken up by the increased magnet
size. Optimally loaded output should be solid to 40Hz with an F10 around
30Hz. Frankly, that's about as far as I'd go with a chambered back-horn;
you can go lower with one but it comes at the price of increased size
and GD, and potentially reduced linearity.

In design terms there are no ports in either Vulcan or Kirishima
-strictly speaking they have horn termini. The former is a rather more
advanced design specifically designed for boundary loading to lower the
frequency to which it's impedance matched and create both a more
efficient and linear load -it has a better-defined upper corner
frequency (acoustic low pass filter) reducing GD in the lower midband.
As such they're meant to be placed in relatively close proximity to the
front wall (and if corners are available, that's theoretically the
ideal), although like all loudspeakers the optimum position for them
will need to be established the old-fashioned way, i.e. trying it out as
only the broader aspects can be roughly predicted in advance with
reasonable accuracy; room construction materials, furnishings, exact
position, rest of system's electrical behaviour and personal taste all
come into this.

Dave,

Do you have phase plugs that would work with the FE208-SOL?
