Ok, so I have a Schroeder cab, 1000watts at 4 ohms, and I haven't been able to find a head to push it appropriately. It's got 2x10s and a 1x12" so im looking for something that will "push that THANG". I've used an ampeg SVT7PRO at 1000watts at 4 ohms, but only to find out that in order to get the full 1000watts you need to have 2 cabs at a total of 4 ohm load so it was really pushing it from one side at 600watts at 8 ohms . I have used an Aguilar tone hammer 500 the 500 watter at 4 ohms, I loved the eq sound of it but it was super weak at 250 at 8 ohms per side, in order to get the full 500watts I needed 2 speakers. I have also used a Crown XLS1500, and it actually blew my 12" inside the 2x10/1x12 3speaker cab into oblivion, because I had it bridged. Now after I have repaired it, I am now using the XLS1500 in stereo only in one channel at 500watts @ 4 ohms and it actually works way better. Because I'm getting the full 500 actual watts into the speaker at 4 ohms. It doesn't sound as weak as the other alternatives but it would be great to find that perfect amp/head to round out the bottom. Is there anything out there that is able to dish out, maybe not the complete capacity of the cab 1000watts at 4 ohms, but at least pretty dam close?? My fear is that if I under power the cab there will also be resistance causing the head/amp to fry.
