Default Best cabinet for Audio Nirvana Super 8 Cast??

I have recently acquired a pair of Audio Nirvana Super 8 cast drivers, picked them up for a great price....

I have been looking at cabinet designs, and am coming up short still. Leaning towards horns, thought about Fidelio, cannot find anything that really is seducing me..

I have a full shop, build audio related stuff most every day, have built a few fairly complex horns, and not seen any that intimidate me too much. Sound is what counts... I do like bass, and understand that this is going to require some compromise in that department. I listen to a wide range of music, including some 'big' music. Just finished a pair of Jordan Transmission line cabs, and really like them for some types of music. Listening mainly through idler decks, Tube phono stage, tube pre, PX-25 main, or SS main. Been listening to Snell Type A IIs for years...

Any opinions on these drivers? Should I get rid of them and not waste my time with them?

What are the best horn designs you know of, and where can I find plans?

Cheers!

No one has done a horn for these yet that i know of, you'd be looking to get lucky installing it in a horn designed for something else.

The AN drivers are pretty good, IMHO, and since you have had plenty of experience with horns, why not give open baffle a try. You can knock it up in half a day. You will need some helper woofers though. Eminence alpha 15 is a good start.

are its parameters pretty well known from several measurements? seems to me existing horns may "work" if simulations don't indicate excessive peaking above cutoff and holes in the response. Bill Woods went through a process of 13 builds (not fully described) to come up with his K-slot back loaded horn. It like others may work if the parameters-predictions fit and if those hold up under dynamic conditions.

Planet10 - when do mix and match horn-driver combo go awry? - is it within predictions? do art & luck sometimes dominate beyond modeling? are there factors which can't be measured? where are the best places to measure blh frequency response?

I may try some open baffles, just to try, I have no experience with them at all. The idea is strange to me still. On that basis alone, I need to try. Still, I love the sound of horns so much, that is probably what I am looking for..

Default An8"

Hello,

i tested the standart 8",
the cast 8" would be also working,
the simulation are more or less identically.

look on my HP plan of
3 SAT horns down to 100 Hz,
and the new double horns
SAXOPHON and RDH20.

100 dB 1W 1m with 1 mm stroke,
bass down 34 Hz.

What about the Lowther Fidelio cabinet, I keep wondering about that one...

Also,, with the open Baffle, how are the 15" drivers integrated? some sort of crossover?

Are they also open baffle?
