Great news looks Alnico, its beyond me why it use cheap large area steel frame, less heat dissipation not to mention resonances. No additional info on its site.
-
When they get it coming.....they will do. They are not the quickest in getting things done. One thing for sure, it will be accessible vs all these ripoff people who charge $$$ just for Alnico label.
-
That is nice. There is many Alnico FR currently than a few years ago,
WB could have go further ahead and do field coil that is rare even today.

This is a pair of field coil Burro’s somewhere in the wild.
-
Fantastique, do you can post or PM me more info?
-
I believe they were a one off by Dave Slagle of Intact Audio.
I have no guess where they are today.

Classic Audio Loudspeakers (www.classicaudioloudspeakers.com) is one such company, and they do offer a single driver system (click on 'Contemporary line' on their website and scroll down to 'T-7). Sensitivity is not especially high for a single-driver system at 90dB, but it is a single-driver, field-coil system.
Field coils were popular back when commercially produced permanent magnets were extremely expensive and copper was not. They were thus a cost saving measure, not for 'improved sound', but there is this mythos about them in some parts.

Nice, I unknow WB made to order drivers :thumb:
-
The Classic audio T-7 is a new offering I think. I haven't seen it before at any rate. I'll try to give them a listen at the show this weekend.

Yay. They need to update their main website with this sort of info instead of FB.

Iam guessing they dont want inform tech specs in its site.
Not a smart name choice also.
-
Specifications will be posted once the initial run of drivers is finished.
-
Great cant wait to see the freq chart.
I mean say the model name ''omega'' already used by Louis at Omega speakers, maybe he could continue with the ecologic theme name, its very friendly.
-
Response chart will look similar to the original Betsy I’m guessing. The new speaker is mostly the same driver but with an alnico magnet.

This not good, a Alnico magnet require other project diferent from Ferrite, the way to design the mobile parts of a Ferrite and Alnico speakers are very different not mentioning the critical VC, according the old school from 1940/50.

I'm not one to respond to lots of forum posts on my drivers, but I'll make an exception:
Of course we didn't reuse the voicecoil from the ferrite magnet. We also used a different spider!
We took what we loved most about the Betsy, and voiced the alnico version appropriately.

Looks nice;

Call me impetuous, but I just ordered a pair of Wild Burro Alnico drivers to try out. The introductory price and ease of setup made for too much temptation. :D

Congratulations Michael, Alnico always worth to try and at this price it was an investment.

Sonic comparison notes of these vs other drivers you had. These cabs you have are OB in the back right?
-
These cabinets have thin walls and an open back. The original Betsy's are great in these cabinets, the alnico need some more break in, but sound very promising.
-
Spent most of the last two days listening and these are sounding very nice. I’ll need to drop the original Betsy’s back in for a comparison next weekend.
Mresseguie, have you had a chance to listen yet?
-
I'm afraid not. I don't have baffles yet, and I'm about to "disappear" into another Asian adventure.
I jumped at the opportunity to buy a pair so that I can set them up soon after I return.
-
Any updates on the Drivers?
-
My Caintuck Betsy baffles shipped today and are slated to arrive Friday afternoon. Once they arrive, I'll attach my WB Alnico drivers; plug them into my home office system, and give them a little juice. I'll give them an initial listen on Saturday, but I will burn them in for a hundred or more hours before any serious impressions. :popcorn:
I'm really looking forward to this.

Very interested in your impressions. Another speaker I would love to hear are the Cube full rangers that 6moons rave about.

Curious, how much for a pair of the AlNiCo Betsys? I knew Randy from years ago with Decware amps (before Betsy). Also knew Darryl Hawthorne and still chat with his original crossover mentor. So have heard several versions of the Hawthornes.
Glanced at the Cube review (can't stand all the excess verbiage in 6moons reviews) - yuck! Expensive, look amateurish (whizzer cones are unevenly shaped), and 3 whizzer cones! (I consider whizzers to be mechanical crossovers.)
BTW I have a nice pair of extended range driver speakers just sitting around: Bob Brines FTA-2000 (he's retired now and changed names of the speakers a couple of times): Fostex F200A AlNiCo 8" drivers (no stinking whizzers), rated 30-20,000 Hz (not a misprint), 8 ohms, 89 dB/w/m, with EnABL applied by Bud Purvine (inventor) himself, $575 each when last available; cabinets are floor standing transmission lines.

Rethm speakers uses whizzers. Even Rollo Audio here on ac sells them. These are very nice sounding speakers. Whizzers are not crossovers. Where do you get your info?

There is a company that is considering on making an active Cube speaker. We will wait and see.

Hi, Jeff.
I'm waiting for my Betsy baffles to arrive (delayed by severe weather). My drivers are the Wild Burro Alnicos. I bought them back in November just days before I disappeared into Asia. Once the baffles clear the bad weather, I'll finally get a taste for how these speakers sound. I think I got the 8" WB for .....gotta check...Yup...$330/pr. I could not pass up this opportunity.
In mere days, I will know how they sound.

Joke? Any single driver speaker is 'active' by default.

As before, where do you get your info?
-
By definition: one channel of amplification connected directly to one driver.
-
Maybe this company will put a amp board fixed direct in the speaker enclosure back to huge vibrations and resonances.
-
A DAC is going to be added also. Room correction could possibly be added. Less parts and cables will give even better SQ. Maybe this could be common someday. It could also have the Alexa app added.
Meridian does this as for a DAC, but they have to do it at each driver. That makes the expense much higher.

Severe weather tried really hard to keep me from experiencing my newest (and first ever pair of OB) speakers, but UPS came through this afternoon to deliver my Caintuck Betsy baffles.
Randy's (Caintuck's) packaging is fantastic. I may borrow part of his method the next time I ship gear. :thumb:
It took me all of 40 minutes to put everything together. I was impatient, so I did not solder the copper wires to the clips. [Shock! Horror!] I crimped the clips onto the copper wire instead.
Because my Apollos are in my living room, and because these speakers need a solid 100 hours to burn in, I placed them in my family room. Way back when I first 'discovered' AC's existence, my audio system was in our family room because it was the only place my wife would allow it. [She finally caved last year and told me to put the main system in the living room. :banana piano:] Our family room was dreamed up in an audiophile's worst nightmare. It's nearly square with a cathedral ceiling facing the wrong way; a wide open space leading into the breakfast nook/kitchen, and an open area above to the second floor hallway. This gaping opening sucks all bass out into a parallel universe. All the furniture in this room is very reflective. To be very candid: It sucks.
Yet here I have placed my new OB WB Alnico speakers....and.....I'm powering them with my inexpensive Nuprime IDA-8 amplifier. My source is my old iPad2. There's a 3.5mm earbud connector plugged into the iPad. The other end is terminated with red and black RCA connectors which are plugged into the back of the amp. The speaker cables are 12g Blue Jeans cables.
The two speakers are 6 feet from the front wall and five feet apart (center to center). I can easily adjust their positions if people recommend it. They sit on a rug which sits on the floating wood floor.
And....it sounds......wonderful.
And that's all I'm going to say for the nonce. [What an odd word.]

Decware also sells the Betsy baffles. You might check out Decware's plans for the DNA Horns. The plans are 20 bucks and it takes less than $400 in parts to make them. That could be your next speakers. :thumb:

Dying to know what you think of them now that you've put a little time on them. Hope to hear back soon.

Steven,
Hello and thanks for the nudge.
In short - I like them. They're my first OB speakers, so I have can't say they're superior or inferior to brand X or Y OB speakers, but I do like them. I have tried them in two systems in two rooms and discovered that synergy (and room perhaps) changes how they sound. That is not a surprise, I guess. Anyway, I already mentioned above the first system using my Nuprime IDA-8 and iPad. The second system is my reference system with Don Sachs amp and pre, SW1X DAC, Ciunas USB to SPDiF converter and iMac streaming Tidal. I expected the WB speakers to sound amazing in this system, but they sounded flat and thin.
They're back in the first system in the acoustic nightmare family room, but now my source is an Oppo BDP-103 connected by an inexpensive optical cable. They sound even better now - so much so that I pulled my boxed up CDs out of storage and I am experimenting with different genre of music. Not too surprisingly, I think, acoustic instruments, female vocals, male vocals, and less complex(?) music sound better than symphonic, rock, and hip hop music.
I'm glad I bought these and the Betsy baffles from Randy at Caintuck Audio. They have a very different flavor to my Meniscus Audio Adelphos monitors and my Apollos.
Will these replace my Apollos? Heck, no. Will they remain with me? Heck, yeah! Will my wife have a fit when she sees them sitting in the middle of the family room? Absolutely! :roll: Fortunately, they are very easy to move.
AC member Gregfisk is coming down for a visit next week. I'll invite aldcoll, and I'll see if I can get a few others to come for a G2G. Then, others can add their comments to this thread if they wish. Greg is bringing two amps (a modded Hafler and an Apollonia (sp?) 1200as2 amp, I believe) and his Lampi Atlantic DAC, so we can get more flavors to try.
If I think of more to add, I will, but this is pretty close for now.

I’ve been living with these drivers in my Reso cabs for a bit now and I’m really enjoying them.
A mod I recommend is removing the dust cap and using a phase plug. It opens up the top end nicely.
(https://www.audiocircle.com/image.php?id=194182)
-
Remove the dust cap will allow dust start came in the VC and gap, getting the use of grids critical.

The plug covers roughly the same area, so I don't see a problem. I have several drivers that have had this done for over 15 years and they show no signs of an issues either. I guess I'm willing to gamble a bit to get a better sounding driver.

Plugs cover just the pole piece, dust/wet will came in between the pp and cone/VC.
