Enough Power?

I have a similar question involving the SVT 3 Pro -

I've been looking at the half stack deal that you can find at a lot of the online corporate stores, which is the SVT 3Pro with the SVT-410HLF. The HLF is rated at 4 Ohms, and I was trying to figure out if I could hook up the 8 Ohm SVT-15E to it, but a few websites I've visited about ohmage calculations tells me I would get a total of 2.667 Ohms set against the 3Pro. All this stuff about ohmage/resistance is frustrating to me and I'm not sure how much power each amp would get or if you can even combine those two different ohm amps to the same power amp like the 3Pro without frying something important.

Any thoughts on this?

It puts out 450 watts at 4 ohms, so you would need 2x8 ohm cabs to get the full 450, or a single 4 ohm.

To the OP: I was about to order that stack too, only with the HLF cab, but then a few people talked me out of it, and I'm glad they did. I'm all set to order a Markbass Little Mark II with an Avatar 2x10 cab. It's way smaller, cheaper, and even more powerful than the Ampeg stack. I'd definitely look there before you bite the bullet on the Ampeg.
 
Well, buying this stuff will be sort of the "long term" investment, ie starting out with the 3Pro/410HLF for inside stuff, and adding the 15E if (God willing) my band survives the winter into doing outside stuff into the summertime. I'm still trying to trick myself into thinking that I'll be playing bass in bands for the rest of my life :rollno:

Really, I just wanted to get an understanding of all this stuff. I have this Ashdown combo amp that is really nice, but I've recently played through some Ampeg and I like it better, so I may be trading in the Ashdown for Ampeg, in which case I'm definitely getting separate heads/cabs, and the 3Pro/410HLF half-stack deal seems pretty sweet, but I want to know if I can reasonably expect to safely hook up the 15E extension if I ever wanted to. I realize how pitiful I must sound right now, but admittedly I'm on a budget and relatively new to the world of bass amplification.
 
You can't hook up a 15E and a 410HLF to a 3 Pro. It has a 4 ohm minimum, and those two give you a 2.67 ohm impedance. Plus the power will be distributed unevenly and it's doubtful your 15E would be able to compete. Get an HE. The HLF's a nice cab, but I like the HE better because it's tighter and not so gigandus on the low end.
 
I'm just using this to play in my garage band, my current amp(fender 210 100w) cant cut through, my guitarist likes it loud, a little too loud at times... but I'm thinking of this as a long term investment as well. Ampeg is all there really is around where I live, not seen a Markbass dealer yet. Ampeg dealer is only 30 minutes away from where I live.:smug:
 
All plug and play heads consist of a preamp and an (integrated) poweramp; so:

An ampeg 3pro consists of a (tube) preamp and a 450 watt poweramp ...

If you already have a rackable premap like the Sansamp RBi, you just can buy a power amp (last stage amplification, that what delivers the power a.k.a. the high watt numbers :p) and put it behind your preamp. The texture of your sound is mostly defined by your preamp (apart from what bass and kind of strings you use ... and effects of course), the poweramp makes it go louder.

It has the advantage that you can upgrade/change your setting/sound with ease.

If your budget is tight, getting a poweramp and a cab is a very good suggestion :D

Ya, that's a good point. You could probably get twice the power for the price of a 3 Pro.
