I now officially have an up-and-running F115. This is the one started by Mike Arnopol, and finished with the help of greenboy and a local Good Samaritan. The old thread about this got a little ugly and locked down, so I'm almost expecting this one to have some issues, thus I'm keeping it out of the overall greenboy threads. I think all the "Mike is a good builder" points have been raised. I'm not here to say that all his cabs are represented by my experience, but instead to tell my story about my particular cab. YMMV (and I hope it does) As a recap on some of the points raised before, and a few not raised in the last thread. The repair/tweak list had the following items: - The big issue was a woofer replacement/re-cone from the factory. - clean the debris out of the tweeter. - vacuum up sawdust, woodchips and metal filings in the cab. - remove a forest of long 23-gauge wire nails that missed their target and were sticking into the interior, ready to impale the incautious. - add a baffle-to-rear-panel strut approximately per the plans. - remove semi-random bits of foam from the cab interior and line it with Ultratouch. also, remove a few bits of polyester fill from the midrange enclosure and line it with Ultratouch. - properly seat the T-nuts. - add spacers to the grille to prevent the cone from hitting it. I saw several interior photos of the cab in various states of repair, including the tweeter debris and original foam fill. The most obvious issue to a casual observer is that there is only one port divider, instead of the two which are the standard design. Each of those two dividers is to connect to internal bracing which is intended to run the internal border of the cab, like a girdle. No such connection existed, and the internal bracing was incompletely routed (I guess horseshoe/hand grenade close was good enough). To be fair, the bracing that runs by the mid chamber was incomplete, but it is almost compensated for by the fact that the mid chamber wall acts as a brace. Regardless, it was not to standard plans. Now, I don't know if that is placing too fine a point on the issue. I can't say it is 98.4% or 92.7% as good as if it would have been done to spec, and heck, it could even be better. My point is it was not to spec. It was pointed out to me that the cab had a bit of a natural ring/resonance which was probably more pronounced than a standard fEARful cab. Aside from that, the real issue is how it sounds. First and most importantly, the "phantom" buzz is gone. The tone is crystal clear. It is a touch less wooly/spongy when contrasted against my Mesa PH115 (my only other cab). It is also smoother and more even across the entire range. It is a tad polite when paired with my Mesa Buster 200 head. I can EQ and pedal in the grit I want/need. I also notice it to be a bit more aggressive/articulate when used with my Monique. Interesting that it tames one amp but enhances the other. I'm still just running things as living room volume, so I'm still curious about how it will perform when pushed. I'm sure the "lack" of lows might translate to boom-free. I'm impressed at how it handles my Nash PB63 through each amp. The high/mid gank isn't as pokey and the lows aren't as bloomy. I think this is where it shows the "what goes in is what comes out" character. I still need to pair up with my JB 63. I usually run the P for more rock and thumping 1/8ths, and the J for more melodic, articulate runs (a sledge vs a scalpel). However, the P is less sledg-y with EQ setting I was using with the PH115. I still need to toy with the switch and tweeter level. I will say that the form factor is a bit less than ideal for me. As I've posted before, I have a physical handicap which limits my strength and range of motion on my left side, from the neck down. The single handle on the "top" makes it a bit awkward for more than a few yards of carry, even though the weight is pretty reasonable. In a perfect world, I'm not sure if a 212 or 2X112 would be better for the schlep. Despite the limits of my left side, a two hand carry is possible, and holding it closer to my torso helps my stability. I have mixed feelings about this cab. It was such a pain in my life to get to this point, and it isn't a silver-bullet solution for my needs. Though, I've greatly enjoyed working with the greenboy community on this issue, and the "scar" is a bit of a war trophy. It is still new, and I'm on no schedule, so time will tell if it stays in my hands or if I pass it along. For now, I'm enjoying the satisfaction of having it "done" and I do like the sound I am getting. . . but I'm a GAS-y guy with limited space, and a bigger gear budget than I "need."
