critique my rig

[chriscalas]

Hey guys I'd like some input on my rig I need to know if I'm in danger of blowing any speakers, or going to mess something up with difference in ohm ratings. I got a ampeg svt7 pro running an ampeg 4x8 and an ampeg 4x10hlf, with a tech21 sansamp. The 4x8 is 8ohms and the 4x10 is 4 ohms, so i know that equals 2.67ohms and I don't want to wreck the head. I play in drop B and I push the bass and treble, cutting the mids. let me know if i'm going to wreck something. Thanks guys!

The only way you'll "Wreck" something is if that head won't take a 2 ohm load. If it won't, I see repair bills in your future... If it will, then you're in good shape. Of course, back might suffer from all that schlepping...

[thesilence]

I checked on ampeg's site and it does not mention that it can handle a 2 OHM load therefore yes you are in danger of wrecking your wonderful svt

[chriscalas]

that makes sense, i appreciate the input

If you want a bit of a deeper sound buy a 1x15". That'll get your low-B sounding sweet.

I can't imagine why the svt7 and a 4 ohm 4x10 wouldn't be enough for most any gig.

is this going to be another 1X15 vs 4X10 thread?

Yeah if your playing that low B alot you'll want a 15" most 10's do not have the low frequency response you'll need to get a nice sounding B

Ooh, this is going to be fun xd. Now we're going to get the talk about phasing issue's and low-end and punch not being dependent on speaker size.

Either of you jokers want to come up with a 1x15 that will actually go lower, louder than the SVT410HLF he already has?

i dunno. all i know is im making popcorn incase

[AwkwardLoudness]

Even if the amp could run stable at 2Ω, there would still be an issue with power distribution...the 4Ω 4x10 cab receives 2/3 of the power, 8Ω 4x8 received the other 1/3. So, 8 of the 12 speakers only receive 1/3 of the power. It makes more sense to use one or the other.

my understanding was that he was getting another cab to add on



edit: reread the original post; what I would do is drop the 4x8

I don't think you would want to mix those cabs anyway. The 4 ohm cab would get twice the power, which probably isn't what you want.

I would either use the 4x10 by itself, or get another 8 ohm cab to go with the 4x8.

[JonathanD]

You title suggests your rig lacks confidence from its' owner.

[chriscalas]

very interesting, my contingent was to either A get another cab for the 4x8 to make a total of 4ohm load with either a 15 or a 8ohm 4x10, or B which I haven't seen addressed I could send a parallel line from my sansamp to my acoustic 100 and that to the 4x8 ampeg, because I'm wicked broke and happen to have that head. I haven't played around with a 1x15 but I have heard about the complaints that it gets a bit farty sounding. yet again thanks guys.

[RickenBoogie]

Lose the 4x8, and use what you have left. It should do well. If not, lose the 410hlf, and look into a larger 4 ohm cab. And yeah, the comments on using a 15 for more low end is rubbish- doesn't work that way. The 410hlf is one of the deepest cabs made. If it were me, I'd opt for a pair of 8 ohm 2x12's.

[rodl2005]

Either lose the 410HLF & get another 8 ohm cab that'll 'match' ok with the 4x8" BUT AFAIK the SVT410HLF IS a VERY low tuned cab & Will handle the lowest notes U can throw at it.
As it's already a 4 ohm cab it will be letting yr amp run at full power & Should be enough for damn near ANY gig.
U definately DON'T need a 1x15" to go under that cab to handle lows. It'll handle 'em easy.

I like 12" & 15" speakers myself, so -eg. IF I were you, I'd get rid of both cabs, & but either 2 8 ohm 2x12"s or 2 8ohm 1x15"s... but that's MY opinion.

Simplest way- sell the 4x8" (unless U want that for smaller gigs- less of a 'lug' ) & keep the SVT410HLF for everything.

The classic pairing with the Ampeg head would be an Ampeg 8x10. that would have all the volume requirements you could possibly need, would sound great, not fry your head, and be easier to schlepp around than your current rig. As someone who has fried a beloved head on a gig and seen the magic white smoke, you don't want to fry your head! Sell the other cabs and get an 8x10, or if you want to be adventerous, the Aguilar gs4x12 is AWESOME! best cab out there if I could only afford it.
