Long time reader; just created a name and this is my first post.
First off - just want to thank all the fellow musicians for sharing their info and knowledge. I've learned a lot by reading the threads here. My hat goes off to you.
I'm in the process of buying a new bass amp. I've been borrowing one for a while now and my band just got some good news and a new member. It's time to upgrade. I've done research before posting this so I have a solid understanding. The question attends to amp/cab compatibility and headroom. So here's my deal:
I have 2 cabinets that were pretty much given to me and they are each awesome. But I never hooked both up together. I primarily use a Hartke 4.5 XL (400 watts at 8 ohms). The other is a Hartke 210 TP (150 watts at 8 ohms).
The amp head I'm looking to get is the Ampeg PF-500. It's specs are max 500 watts at 4 ohms and max 350 watts at 8 ohms. I want to have some versatility with my rig set up (if possible) so I can use just one or both.
So here's my question.
If I use just the 4.5 at 400 watts at 8 ohms, the amp will run at 8 ohms max 350 watts. That's 50 watts of headroom.
If I use both cabinets I'll get 550 watts at 4 ohms, and the amp will run at 4 ohms at max 500 watts. That's also 50 watts of headroom.
Is the amp I'm getting a good fit for my cab(s)?
Is 50 watts of headroom enough? (I know headroom is the difference and I know going to low can sometimes damage the cabs by not getting enough juice; and going too high can blow'em - so there has to be a sweet spot, no?)
Also, the difference in the headroom between both setup options are 50 watts. But does the difference in max wattage (350 vs 500) make one option better at the 50 watt headroom?
I feel I may be over thinking this but better to be safe than sorry. If I'm buying a new amp, I at least want to check with people first. Thanks again for your help everyone. Rock on
