So, should I expect reconed Wharfedale Super 12s to "pack some juice" compared to modern ceramic pro-audio speakers?

Maybe... are they the alnico or ceramic Super12s? The alnico may need to be recharged to get the most out of them (actually likely)

I tend to buy more ceramic vintage drivers them alnico because they have a better chance of performing the way they should. I like neo because there the powerful. And when it comes to tubes that matters. If alnico's have a more stable impedance that matters to me too because I mostly build SE so I would like to see evidence of that. I personally am still trying to find a local speaker guy that can remagnetize. If I could I would buy more old alnico. But I just have been disappointed to many times. Ticonal lasts better I think. A speaker with 92db I am not interested in. It has to be better then 94 to catch my interest preferable 98+ the environment demands it! More efficient speakers smaller amps.

They're alnico. Who out there recharges magnets, and how much does it usually cost?

I to have been bitten by the Audio Nirvana bug. I have built 3 pairs of 2.8 Ambience cabinets. I sold 1 pair to my brother-in-law, I listen to one pair, and my wife is asking me to sell the third pair. I really love them and think the Audio Nirvana brand is a great value.

If anyone is interested, I'm selling a pair of 2.8 Ambience speakers made of 3/4 birch. The front firing drivers are Super 10" and the top firing drivers are regular 8". The speakers have the 6" port that I'm using a port tube with to fine tune the bass. The bass is very dependent on speaker placement. The port tube helps with this. Corner placement is the best.

I'm asking $430 for the pair.

I'm located in Richmond, Va.

Sorry if I sound ignorant, but I don't understand this statement. Do you mean that the cast frame drivers are better in mids and treble? My application will include woofer augmentation at about 150-200 Hz so extended bass is not important, but mids and treble quality is. My only decision now is stamped or cast for a super 8.

cast hands down. I have both and even though they sound alike, the cast frame beats the stamped when wanting ultimate rigidity.

Okay. Just trying to understand the differences. If they sound the same, what else is there? In other words, what does extra rigidity buy you in a speaker?

The AN drivers do have massive magnets. The biggest I have ever seen on any driver. So, getting cast-frame should provide some benefit. Still, any improvement must be miniscule compared to say, properly bracing a cabinet.

Lovely speaker. I like the dark red-ish finish. I might have to do something similar to please the missus
