Field Coil Alpair 12?

[_henry_]

i wonder if anyone notices this

AFFIRM AUDIO - Elation Loudspeaker

i had privilege to listen their early light gold alpair 10 prototype last year.

but this is BIG NEWS!!!

as i notice FIELD COIL being choose for the ultimate options from FEASTREX, VOXATIV & LOWTHER now.

I wonder what would be the effect on ALPAIR 12?

cheers

I'm 55 and when I was a young guy in elementary school, I think I read that electromagnet-field speakers sounded great because a field coil can produce a more powerful magnetic field than a permanent magnet. Now days we have the ability to produce plenty of low ripple, regulated DC to run a field coil, so such speakers should be able to produce great results. The option of adjustable magnetic field strength in a speaker sounds pretty interesting to a tweak like me!

the initial production run (10 pairs) of the Alpair 12 will be in 2011.
Field coil manufacture and final assembly is for Affirm Audio by Dave Slagle and Jeffrey Jackson

Price is expected to be c $2500 per pair.
Though FCs are never chaep . .

The Affirm/Impact field coil is based on the Alpair12, not the 10.

Availability is awaiting ironing out of production logistics i understand.

Not too bad, Lowther FC will be $6000.
I've heard the lowther proto FC's, and the 80,000$ Feastrix 9FC.

Supravox is c $3000

The use of field coils has always perplexed me. If the expected price is reasonably accurate that is approximately an 800% increase in price over the standard alpair 12. I'm just a skeptic I guess.....but for the small or negligible increase in performance the increased cost will likely not be worthwhile for all but the most wealthy DIYers.

A question i asked too... but in the form of how would an Alpair12FC compare to an Alpair 12eN.

A field coil will not solve the problems that an EnABL process will solve.

I did provide a field coil to Romy, to experiment with on his horn loaded drivers. The diff between 1.1 and 1.4 tesla, as measured in the gap, made a large difference in tonal and transient character. Romy was never satisfied with any position in between, nor the extremes. His comments were that the alnico magnets, with a proper charge, still provided what he found interesting in sonics.

Jon Ver Halen is eagerly awaiting a pair of field coils to attach his beloved EnABL'd Lowther PM6A 16 ohm silver voice coils on to. Hopefully with an adjustable field strength.

I would personally expect improvements in fine detail and added color contrasts in both inner note gradient and transient decay. Both of these would be characteristics that an EnABL'd radiating surface would aid in expressing into the room.

The Affirm/Impact field coil is based on the Alpair12, not the 10.

i was actually referring to the alpair 10 they used on their maxxhorn/affirm before.

mark mentioned to me that it was design to be more "revealing" or tendency for the high freq region. i guess to compensate their design which put emphasis on the bottom end.

I have not heard any field coil drivers, but the trend now seems that is the " ULTIMATE " driver.

probably for its versatility to suit the listener taste? (by adjusting the voltage and current?)
