4 Hartke HX112s and LH1000?

bassgrant · #1 02-07-2011, 08:20 AM

So how about four Hartke HX112s (stacked) running at 4 ohms each, powered by an LH1000 in parallel mode so that each cab gets 272.5 watts.
Anyone else think this would be awesome?
Anyone have the ability to test the theory?

That's a 1 ohm load, so the amp would last maybe one rehearsal before it died. Not sure that it would sound an geeat either

No because the lh1000 has two power cores with each one capable of handling 2ohms. So each pair of 4ohm cabs would give a total impedance of 2ohms. So the load would be fine

I think Cut is right. You should use all the cabs in 8ohm mode.
Every side supports 4 ohms

I don't understand. The unit is quoted at 2x 545watts @ 2ohms or 1x 1100watts @ 4ohms so two lots of 2ohms would be ok right?

according to Hartke specs, the LH1000 in dual parallel mode will do 2x 2ohm loads which would support qty 4 4ohm cabs total.......2x 4ohm cabs per side
so, according to this, your goal is supported by the LH1000......

is this tonally the best option.......your ears will have to answer that........

bridging supports 1 load (not necessarily 1 cab).....minimum 4 ohm load one time...so for your goal, be sure not in bridge mode

Sorry my bad

You are right bassgrant.....

Agreed. I'm only talking hypothetically here because i love my 410/115 hydrive rig with the lh1000 but having such a high level of modularity in a vertical line array seems very appealing. I guess dispersion would be vastly improved and the sound would be at a really nice height. But thats my opinions. Anyone who's tried out a 112 or two got any ideas?

The 'agreed' was to whitbass by the way. I wasn't being gloaty to you gillento. Thanks for trying to help anyway

2x12" (4 ohms) with a 500 watts amp is my typical gig setup (either the LH-500 or the Markbass SA450).

I've never run into loudness/volume problems with this setup (apart from a giant outdoor stage, but monitoring was perfect)

Right now I am using the db212 and 112 but I am thinking about getting myself a Hydrive HX112 duo as well

@bassgrant: no worries, I don't feel being gloated

No experience with this particular rig, nor with using (4) 1x12 cabs, BG. But I've often considered this could be a very flexible and powerful type of rig to own. I'm surprised that more players don't gravitate toward using a 1x12 tall stack such as this.

My suggestion is to go for it. Frankly I think you might like it a lot more than your 4x10 + 1x15 rig. Main consideration would be to physically stabilize it with a lightweight aluminum or fiberglass frame of some sort - to minimize the possibility of it tipping over - especially when using it on a sloping floor, since the rig with head on top is likely to have a high center of gravity...

Very true. Maybe having the head on a stand to the side would be a good idea? That would make the twelve stack loads more stable (i would have thought...). Thanks for the views mm

I can attest to HALF of your proposed idea, and the set-up RIPS!!

Using (2) HX112 cabs with my LH500. So in theory, with both cabs at 8ohms, I am only sending 250 watts to each HX112.

It is ridiculous to me how articulate you can tune this setup.
You can also go full on growl if you want.

Currently I am running the top cab with the tweeter in the 6db roll-off setting and the bottom cab with the tweeter defeated. I did this to "copy" my Aguilar DB112/DB112NT set-up.

Larry has hit a home run once again in my opinion.
I will be honest, I am definitely thinking about an LH1000 and (2) more HX112's for our summer run of outdoor gigs!!

Hey, 45cmckay105,
Not to derail this thread, but I was wondering about the differences in sound between the HX112s and the Aguilar db112s.

I am thinking about getting a couple of HX112 myself and I am regularly using the db212 and 112 with the LH-500 and other amps.

What is the difference?
