Double Bass EA Wizzy 110 Review

Dis here is the only direct comparison that I have spotted, at least in this forum.

That link is to my comparison, so I figured I would add some more impressions. To answer one question that has been asked, I wouldn't dump my wizzy 12 (not M-line, btw) for just the 10. I like having them both. On the other hand, if I could only have one, it would be the 10. This is largely based on the weight/size issue though. I actually think the 12 sounds a little better in many situations for me...but, since I got the 10 I don't think I have brought the 12 to a single gig. This is mainly because I am incredibly lazy and the 10 is lighter, smaller and fits in my car better.

One thing I have noticed is that the two cabs sound better with different pickups/mics. With the 12 I had been mixing a Full Circle with an AKG C411 contact mic with great results. For some reason this doesn't sound as good through the 10. However, I have recently been mixing a mic (Electro Voice RE15, just shoved under the tailpiece) with the Full Circle and this combo sounds better through the 10. I think the 12 sounds a little better if I'm using just the Full Circle.

So, to sum it up, I think the wizzy 10 and 12 are both keepers and are both great cabs, but if you are as lazy as I am, the 12 might start gathering dust pretty quickly.

OK so excuse my ignorance but why does the Wizzy 10 have 2 speakon jacks on the back? Does the second one act as a thru to another cab? Or can you hook 2 cables like on good hifi equipment?

It is so you can 'daisy-chain' one cab to another. You do not run two cables to the amp (bi-wiring, for you home audio buffs).

I'm a slab player,.....

Has anyone else noticed a tendancy toward low-note wolf tones and middle-range phase weirdness in these cabs? I'm curious if it was just my ears that day, a tic of the room I played in or the cabs themselves. The A octave either distorted or was almost inaudible with the 12, playing alone, which was kind of odd.

I also play slab primarily and how you describe what you heard with the EA's (on that day, in that room, with that setup) is what i used to hear from my UL-110 before I sold it. I used to describe the UL-110 as having "a hole in the sound". Debate has ensued ad nauseum about Neo vs. Ceramic magnets. I'm now carrying Bergantino & Bag End cabs for my gigs (slab & URB). I went full circle. Lightweight stuff back to heavier, trad. designs.
No more wolfs, holes etc..

well I dont know what to think of it but now that I use the EA cab it seems like the faze is reversed. that is with nothing else changed in the SC the wizzy sounds better with the notch then the HP. Dunno and I just use it that way...

2.667 ohms I believe

Indeed. Treating impedances as simple resistances,

RT​=(R1​R2​)/(R1​+R2​)

where RT​ is the total and R1​ and R2​ are the impedances to be combined.

So, if you combine two 8-ohm speakers, the combined impedance is 4 ohms. If you combine an 8-ohm and a 4-ohm, the combined impedance is 2.7 ohms. If you combine two 4-ohm speakers, the combined impedance is 2 ohms, etc.

If you say so. :)

That, I actually did know, but one thing has always bothered me about that is (in layman's terms) that it seems counterintuitive to pair an 8 ohm speaker with a 4 ohm speaker...seems like the 4 ohm would seem louder than the 8 ohm, but maybe that has more to do with other parameters. See picture above...

Okay, okay. I put the equation there so folks could have it and play with any two combined impedances in the future. Take two resistances, multiply 'em together and divide by their sum. That's your result. You might have really not liked if I posted the general equation that reduces to that simple little rule when you only are combining only two. Please don't shoot me, but here it is:

1/RT​=1/R1​+1/R2​+1/R3​+ ... 1/Rn​

Your intuition about combining a 4- and an 8-ohm cabinet is pretty good! When you place two loads in parallel, the voltage across them is the same but the current drawn, and thus the power, is not. You will have twice the power into the 4-ohm cabinet as into the 8-ohm cabinet. If both had the same rating in terms of sound-pressure level per watt, the 4-ohm cabinet's output would be 3-dB greater than that of the 8-ohm cabinet.

As far as cavemen go, it is likely that, compared to you, I would be judged one on DB! I think it has something to do with the fact that that's your day job and this stuff is mine. :)

I like to help to de-mystify this stuff in part so my bass brothers and sisters don't get ripped off by less-than-informed or less-than-truthful sales people.

Salesman: "Oh sure, Mr. Fitzgerald, this amp is well worth the extra dollars. After all, it's twice the power!"
Chris: "Big deal, that will get me a whopping 3 dB-- no thanks."

:cool:
