Arnopol 8 Cabinet - A Winner!

[Badong]

Any Markbass lovers out there tried this cab with one of those heads?

[Roger Mouton]

Just HAD to get on this thread! Sorry. Apparently I wasn't subscribed the first time I saw it. I had inquired about a 2X8, looked at a thread long ago and then overlooked it. Well, I just spoke with Mike Arnopol and after that, went looking.....................

WOW! Forgot about the Crazy 8. I'm reminded of Will Smith in the movie "Men in Black" when he was admiring the tiny weapons. "Man, I gotta get me one these"!!

Thanks to Mike for the innovation.

How does the F112 compare with the Crazy 88, both tonally and in terms of volume?

I was thinking of ordering two 88s as I play URB with a pretty loud big band but my amp has a minimum impedance of 4 ohms.

[Mike Arnopol]

The F112 goes louder than one 88 but not as loud as two 88's.
Tonally I think that the 88 is more nuetral and more hifi although the f112 is less aggressive in the mids than previous Greenboy cabs.

What I can do with the 88's---I can rig them with a switch that changes it from 4 to 16 ohms. That way if you're playing one by itself---4 ohms. But when you combine the two at 16 ohms you get 8 ohms. An amp that delivers at least 300 watts into 8 would be fine.

What I love doing with 2 88's is have one horizontal on the ground and the other on top in the vertical position. Great floor coupling with the horizontal one and the vertical one puts the top 8 at about 30"---the dispersion on the 8's is so good that you can REALLY hear yourself.

I prefer the 88's for upright and if you use a fdeck HPF they work great for electric, too.

This is a definite possibility!

Looking forward to getting my 8 (from Mike). Should be soon by now I'm guessing. :-)

I've searched this forum to see if anyone is using the crazy88 as an extension speaker for an AI ten2. I would like more forward-firing action for some of the louder gigs. Does anyone use this combination or can anyone comment? Thanks.

Yes I use a markbass 800 tube with a crazy 88 cabinet- sounds great. Looking to get another 88 in a month.

good luck.

I have a Crazy8 and a Crazy 88, and wouldn't mind having two Crazy88s. They're great cabs! The only thing I don't like about 'em is that so few bass heads can drive a pair; I'd like to try some of the new heads, like the Tecamp Puma and Aguilar TH500, but most of them can't accommodate a 2-Ohm load.

Mike, years ago there was a thread which stated it was impossible to make cabinets go from 8 to 4 ohms. The cabinet was accugroove. You probably remember on the threads here. They had a switch on there earlier models, many said it can't be done so they took it out. This was a serious problem that stayed with them. Can you please comment. When you said "What I can do with the 88's---I can rig them with a switch that changes it from 4 to 16 ohms." It brought memories, that made me truly sympathize and at times empathize with these guys which I am sure had a major cause on there problems. Overall, I think they made a very good cabinets with the Jr, the tri 12l and there tri15l. I don't want to make a big deal of it. Just how can it be done?

Completely different situation. 4 to 16 is only going from parallel to series wiring of the woofers.

I'm sure Mike will answer this better than me, but this is a very different thing. Making a cab switch from 4 to 16 is easy...but 4 to 8? Not sure how that would be possible. Two 8 ohm drivers can be either 4 or 16ohms...the one thing two 8ohm drivers cannot be is 8 ohms

[DoubleMIDI]

4 to 8 Ohms with two 8 Ohms speakers works only by switching one speaker off completely (or separate one to a second input for a different power amp).
But I'm sure this is not what the users expect from such a switch.

Out of curiosity, what's the change in SPL going from 4 drivers wired in parallel (2-Ohms), to 4 drivers wired in series (8-Ohms)?

Not sure, but in the case of two C88's, youd be at only 8 ohms with a series wiring, as i understand.

Thanks! Corrected.


From another source: the difference in sensitivity should be 6dB.

[fdeck]

The magic setup for an impedance switch would be six drivers, of 6 Ohms each. Wired one way it would be 6x3/2 = 9 Ohms -- close enough to 8 for all practical purposes. The other way, 6x2/3 = 4 Ohms.

Still hoping to hear from anyone who's used crazy88 as an extension cab for a Acoustic Image ten2. Any takers?

Maybe there should be a Crazy6x8 in the works.
