Default First Watt F1 with Audio Nirvana Super 12?

Hi folks,

I'm wondering if anyone has used a First Watt F1 design with the Super 12 driver from Audio Nirvana? The reviews of the F1 with full range speakers are fantastic, but I haven't seen anything on how well it might work with a driver larger than 8". Probably b/c there are no other 10 and 12 inch fullrange drivers (if Common Sense Audio's webpage is correct).

It seems to me that they'd be a great match, but I worry I'm missing some of the implications of moving to a larger driver...

Thanks,

Roscoe

I have a pair of super 12's due in tomorrow, and some stuff will
start appearing on them after a while.

I don't know how the F1 will drive them, but from experience, if you
are willing to work to develop a network in parallel to make the
interface, you can get pretty good results.

If you haven't read the pieces on Full Range Speakers + Current
Source Amplifiers and Crossovers for Current Source Amplifiers
( www.firstwatt.com ) you should take a look.

Lacking other information, you can consider "regular" sorts of
amplifiers, like an F3.

I have the 8's running with the ZV9. It sounds great.

Mr. Pass,
Would you be so kind as to let us know what you think about your Audio Nirvana speakers when you get the chance? I know you just got them in so it may be a while. I have not seen very many posts about AN on DIY and yet I have been in a quagmire about whether to buy the AN super 8, 10, or 12 versus a pair of Fostex. Your opinion obviously is very valued around here and the next amp I build will be the F5 ( I have been following since about 5th post -Thanks for a simple design. I think I can handle this one ). I am reading your paper on high efficiency speakers and current source amps right now.
Hope you or others will share your/their NA experience and maybe even have a preference versus Fostex.
For me, I have only experience with the 4.5" FE127 with a K-502 tube and a Harmon Kardon 135. I really like it but the bass is lacking and the recording quality is shown with no shame by these speakers. So just when I think the speakers are not very good at all, I pop in some Tracy Chapman or Bruce Hornsby and they sound wonderful.
Anywho, sure would love to know what you and others think of the AN line.
Thanks so much
Uriah

I am preparing a series of pieces on open baffle design with full-range
drivers, and I have 6 different Audio Nirvana drivers which will be
part of that.

Mr. Pass,
Will this be posted on FirstWatt? Approximately when should I look for it?
Thanks so much,
Uriah

Default My AN 12s just arrived as well...

Just got my AN Super 12s too. Sadly it'll be a while before I can get them in something and hooked up.

I'd been thinking of building the box that Common Sense Audio recommends for these drivers, but am curious about the decision to try these drivers in an open baffle design...
