Bi Amping SVT 4 Pro

[bassdan9]

Hey all,

I'm trying to bi-amp my svt 4 pro into a 2x15 and 4x10.

I have all the connections correct but,
what should I set the crossover frequency knob to?
I want the 2x15 to take the low B load and the 4x10 for everything else.

Doesn't matter, they're both fullrange cabs. Just turn it to wherever sounds best.

+1 when using full range bass cabs, it's just a matter of finding the spot that works best for you. Now, if you were to use cabs specifically designed as sub-woofers and mid drivers, that's a whole 'nother thing.

Turn it to whatever sounds best. Maybe try the 200hz area as a start. Subwoofers at shows are typically crossed over around 150-200hz.

Is the SVT 410HE a high frequency driver cab or full range? The description on the Ampeg product page describes high frequency but it is not altogether clear to me.

I have a SVT18 which is a low freq driver cab. A local music shop has SVT4 and 410HE for a decent deal so I was considering this combination for bi amp rig.

The SVT18 is 4ohm, the 410HE is 8ohm. Is this an issue if running in bi amp mode on the SVT4?

Is there anything else to consider with this type of setup?

410he is full range but it has a high frequency tweeter along with four 10"s. Would not be an issue with the 4 Pro, and might work out quite well. Johnny April from Staind uses a version of that rig, although his has two 810's and two 218 cabs

Does SVT4 have 8 ohm taps?

Generally speaking you don't want to be carrying around large full range cabs to do only mids and highs.

 

[JimmyM]

SVT 4 Pro is a hybrid, so no taps at all.

It might work, but you would be carrying around a heavy 4X10 to do the work that a good single 8" mid driver is supposed to be doing.

So the SVT4Pro biamp set up could be:
SVT18 - low freq on amp A
SVT410HE - full range or high freq on amp B

Crossover control would only apply the low freq cab

I am assuming also, that since each cab would be run by a separate amp within the 4pro, there is no issue with the impedance mismatch?
Amp A has 625W rms @ 4ohm available for the 18
Amp B has 350W rms @ 8ohm available for the 410

Good point. This would not be a light set up for sure.

 

[JimmyM]

No impedance issues.

Hi. I stick to this topic. I've got svt4pro and use only 410hlf as a full range cabinet in mono bridge. How shoul I set crossover to get the best results ? (where is the "flat" in that case ?) thx

The idea of bi-amping is to setup two speakers - one to do the lower frequencies and the other to do the midrange and higher frequencies. There is no point in setting up a bi-amp setup on one cabinet as you will only be hearing the lows or mids/highs. Unless you have some unique plan in motion, you will need another speaker cabinet. Stick to full-range on one cabinet.

 

[Downunderwonder]

I would love for someone to stick a 18sound mid in a little sealed box and connect it to the highs and see what happens when you tweak the crossover. Cheap way to get fearful performance when you already have the biamping onboard.

I ran a 4-10 electro voice cab bridged mono on my ampeg pro 4 for years sounded great, 2 months ago added a T18 E.V. and bi-amped it T18 into Channel A , 4-10 into Channel B crossover set at 100hz. and discovered amazing tone and separation ,articulation this is what a Bass should sound like never going back to bridged mono again, and Yes my 2 month old Aguilar DB751 is for sale.
