I have an Ampeg 410HLF, Nominal Impedance: 4 Ohms Program Handling: 1000 Watts RMS Handling: 500 Watts Sensitivity: 98 dB and I'm looking at the Ashdown Mag 600H head with a 575 watt RMS with a minimum impedance of 4 Ohms. So I've got 3 questions 1. Is the Mag 600h worth even considering? 2. Would I be safe running the two together? 3. Or should I run my 4 ohm eminence with it for a 2 ohm load? I tried searching a lot and I just got confused further!
Maplewood, eh? I'll bite... 1. I've heard the Ashdowns being labeled as non-versatile, but I haven't ever played them. Based on your username and myspace, I'd say run with something like a used GK or Ampeg. edit: Most Carvin amps sound freakin' sweet and go down to 2 ohms. Also relatively inexpensive compared to other brand names due to there being no middleman. 2. You would be safe, if by "running the two together" you mean the head and the cab. 3. Do not do this unless your amp can do down to 2 ohms. Remember: you can hook more than the minimum impedance, not less. edit again: This last bit is not right. Your amp will tell you what it can and can't do, so just stick with that. IE: if the amp says 300w @ 4 ohms or 200w @ 8 ohms, you probably shouldn't hook anything up higher than 8 or lower than 4. Confused yet?
I know you haven't checked out an Ashdown rig first hand but as far as Ashdown amps not being versatile, that is one of the biggest myths going in the amp world. Ashdown amps are very versatile and some times its not the amp thats not versatile but the bass that you may be playing through the amp. And yes I endorse Ashdown(over 10 years).
Actually traded my 18" carvin for a MAG115 and it really does kick plenty of butt, so I retract my earlier "non versatile" statement.
