Two SVT 3 into one speaker Cab?

Fendersaurus · #1 06-11-2010, 10:26 PM

I've been looking at increasing my power for my rig, but with my recent purchase of a new Rickenbacker 4003 I was wondering whether I should buy a power amp to add to my SVT 3 or buy another SVT 3 so I can run it in stereo. That's more the easy part but I would like to know if anyone knows about what it would be like to put two SVT 3's into one cabinet (I currently own an ampeg 810HPC). Thanks

Plug 2 amps into the same cab and you'll be in the market for some new amps in about 30 seconds.

Get a 4-Pro.

4 pro only has one input and one preamp channel, defeating the purpose of what he's doing.

and actually, i believe the 810hpc has either a single 4 ohm or two 8 ohm inputs, correct? if so, then connect each amp to an 8 ohm input and you're in business. if not, don't try it as you will blow up your rig real good.

Thanks. In the manual "The Speakon® and 1/4” jacks are wired in parallel, allowing easy daisy chaining from one speaker to another. Each of the jacks may be used as an input or a through connection."
If the cab cant split to 8 ohms could you use something like a "y" cable for i.e. from out the back of each amp the two cable merge into one and into the cab?

absolutely not!

i think radial makes something where you can use two amps into one cab, but i'm pretty sure you can't use both at the same time. you could rewire the cab to where half the speakers go to one 1/4" jack and the other half to the other, that's about it.

Well thanks your help is much appreciated

For most cabs, this is a terrible idea that will wreck at least one amp in short order.

There are a few cabs that have the option of running two different heads, but they're fairly rare. IIRC there are a couple 8x10's that can be played as two 4x10's.

Unless your cab specifically says you can do this in the manual, do not try it.

Even if you managed to do this, the volume gains in doing so would be so little, you'd likely not notice.

Well, connecting two 3pros to 810 8ohms inputs won't be much louder than one 3pro at 4ohms input. So if you just want to increase power... well, you have to increase the power

But I might be wrong and these adittional ~100W might be just what you need.

But at first I'd try to set more gain on 3pro. I just can't imagine that this setup too quiet. I'm in a 7 piece rock band, I have 3pro with 810E and I'm pretty convinced that this rig would easily rock on the Wembleys or Madison Square Gardens scene.

NO!

The OP said he wanted to increase the power of his rig. The 4-Pro will do this.

If it's more volume you want, it's more speakers you need.

Well, the second SVT-3PRO on another 8x10 doubles the power AND amount of speakers ... pricey but loud

he also wanted to run his rickenbacker in stereo, which the 4 pro won't do.

Wait....... You want to use the stereo output of your Ric through a single cab?

Fendersaurus · #17 06-12-2010, 08:47 PM

Ok. Obviously I'm going to look at other options. I there a chance you can bridge the two amps

will33 · #18 06-12-2010, 09:28 PM

If you want to use stereo outputs from the bass, you need to have 2 rigs...or...at least a rack type rig with a stereo/PA type power amp to put one in each side. That's assuming you have a preamp with two in's and out's, or 2 preamps or a mixer.

No. but the question is.... why would you? Even if you could run a pair of SVT 3's through a single cab - all you're doing is busting your cojones to end up with a mono signal. Doesn't seem to make any sense.

Why not EQ/distort/effect the signals and bridge them before the power amp? ... or even before the preamp? IMO the Ricosound is only really useful if you're going to run them through 2 completely different rigs. eg: run the bridge through a tubescreamer and Fender Princeton.
