Speakers for low power amps?

Any of the 8" Lowther models or 8" Fostex models will work in that enclosure.

You can also use smaller diameter drivers, by making a smaller hole for the driver.

I used Lowther EX3 drivers in mine.

Twl...Any thoughts about use of these FR drivers in an "open" design. Since LF is such a big problem, why not just use a separate LF driver in a box that would be smaller than the horn that the FR driver would demand. You could still run the FR driver without any X/O.

El, yes that has been done by people on occasion.

The big issue becomes integration of the drivers, because the Lowthers are so fast that most subs or LF drivers don't keep up, and sound sluggish. Sort of the same problem that occurs when trying to match panels or ribbons with many bass drivers. Hard to integrate.

But, it is one way to get deeper into the bass.

Good thinking.

I don't know if they're available south of the border, but FAB speakers, especially the 97db efficient Model 1, are a lead-pipe cinch for low-power tubes. I'm toying with the idea of getting a pair to replace my Coincident Total Victories - looking to get a close to a "SET-driven electrostatic" as possible.

I have a pair of C&C Abbys, but for all that they do well they lack too much in the dynamics, extension and neutrality departments for me to consider them a serious speaker.

Gliderguider, I went to the website and those Fab 1 speakers look pretty cool.

Good extension specs on the low end too.

The Abbeys are nice, but they're not like Lowthers. The Fostex drivers just don't have the speed and detail or efficiency like the neodymium or alnico Lowthers do. Don't "cross off" the single drivers yet, until you hear a set of well broken-in new-series Lowthers in a good pair of cabinets.
