hey guys,
just about to upgrade my rig, at the moment, I'm playing a MIA fender jazz deluxe through a Markbass 12"combo hooked up with a markbass15 RJ. great sound, but need a bit more top end. there is a Ampeg SVT410HE going cheap, what do you think with that paired up with a little mark800 and the 15"???
or should i spend over budget and get a MB4x10 cab to match??
Cheers for the feedback.
1) Don't mix sealed cabs with ported cabs.
2) Don't mix ported cabs if different design for the cabs relates in considerable deviation of group delay at the low f-band. THIS is independent of driver size and can (theoretically) happen just with identical drivers loaded into different cabs. The chance to run into issues is slightly with even plausibility to cabs, and therefore independent of driver size.
If you read TB discussions carefully enough you will easily recognize that (as it just can be read on several current discussions) that TB ers dont bother about different cabs with matching driver size. At least they speak no warnings like so often addressed to the "can of worms" 410+115. That's a pure contradiction in itself (it's a paradox IMHO).
3) Don't mix cabs where HT response or cone response of drivers like 6" competes with response of (the other cab) woofers.
That's an "issue" that comes along mostly with different cabs loaded with same driver size. Woofer response is often somewhat different at the treble band thus crossover network for the HT is (often) different. In this case HT response may compete with woofer response of the other cab. Adding a 115 cab then this issue is less relevant because 115 cabs have different dispersion, mostly less response at the top end, and are mostly postioned at the bottom with the HT turned to off.
If I read correctly between the lines then currently a TB member asks for options how to solve those referenced "issues" with his "nearly matching" cabs.
4) don't put a 115 on top with HT turned on instead of the 115 cab at the bottom with HT turned off.
Self explaining if you read carefully 3)
Reading TB discussion carefully enough it is often suggested to put the 115 on top instead at the bottom.
IME that's plenty of good bet to run into sound issues.
In this case, that means if the cabs are wrong stacked and the wrong HT then turned on, no wonder this combination THEN receives so many sad reviews.
Sometimes folks try to do things that absolutely make no sense like put a 115 at top and 10's at the bottom.
I myself never had issues with the mixing of different driver size but, I never did such stupid things that make no sense and therefore would run me into trouble (terrible sound).
