8ohm ?

The accurate answer is "it depends".

My hunch is that the 410 is reasonably rated at 300 watts (likely the "RMS" value) and you should be fine, though if you driving the amp hard enough that you are clipping the output significantly the question becomes harder to answer... maybe.

Thanks, Agedhorse! Yeah, I'm thinking that what I may just want to do is to ditch my 300w Hartke 410TP cab for something like an Ashdown Rootmaster. It weighs around half of what the 410TP weighs, but is rated 600 watts RMS, they say.

@Haunted House ,a couple things...
Our gear isn't a lightbulb. There are not full seconds, let alone minutes or hours where our cabs see the maximum output the amp is rated, with few exceptions.

Also, a bass guitar signal that many players would want will cause physical damage well below the electrical or thermal limit described in a cab's specs for the vast majority of them.

As well keep in mind that depending on many factors, the position of the volume knobs is not an indicator of how much power we are actually sending to our cabs. Many amps have given us their all by the time we get to 1 or 2 o'clock. Generally speaking every knob, switch or button in the signal chain is a volume knob of some sort. SO, if one were to use contour or shape circuits, some fairly high levels of eq boost, a hot pickup, etc, your amp may be hitting the cab with some pretty major power spikes on low - note attack.

Yes, I think that your PF500 would be a safe match for your cab, and/or your proposed one. When used sensibly, most cabs are safe to use with most amps. Personally (IME, IMO, YMMV, MY $0.02) I like a 2:1 or higher ratio of RMS cab rating to amp output. I cant always have that, (for example, my Genz Benz Shuttle rig is closer to 1:1) but when I shop separates I like to do it that way.

Good info, thanks! I appreciate the reply. I probably will go ahead with the PF-500, I think.
