Well earlier today I finally got to try the PF115HE, the only PF product I haven't tried. Used a PF350 to power it. Now this is without the benefit of ABing it with my double baffle cabs, but I'll tell you...it's about as close to that sound as I ever heard out of another cab. Very well built and solid, gets even closer than the B100R, IMHO. Very similar low end response, and with the tweeter defeated, it sounds like it's crossed over at 4k, which is what you want in a B-15-style cab. And the tweeter is way better than I ever expected. It's a compression driver instead of one of those crap piezos, so it's way smoother and not at all brittle. It has a 3 way switch to make it full-on, -6db, or off. I'm not a tweeter fan but this one is pretty tolerable. The PF350 does 250w at 8 ohms, and I cranked it way past the point of offensiveness and the cab held together very well without breaking up. Don't know if I gave it full wattage but I sure tried for at least a few seconds. I liked the PF210 very well, but the PF115 really nails it as far as I'm concerned. It might not be a dead nuts match, but it's got the B-15 sound.
So now I've finally got to try everything out in the PF line. Honestly, I've tried to find something not to like about this stuff just so you guys didn't think I was an unrepentant Ampeg butt-kisser, but there's nothing not to like that I've found. Even the limiter button on the PF350 and Micro VR (they have the same preamps), though I wouldn't use it, is pretty decent and fairly unobtrusive. And though I prefer the 115 to the 210, it's not by much...both of them have a very B-15'y sound, and I could see people preferring the 210's slightly tighter lows. I'm really impressed by how close they nailed the sound of a B-15 with this stuff. What's really amazing is how it's all made completely different from the old stuff, but somehow it all sounds like the real deal.
