Agreed. I have a Rythmik SE12 for my LFE subwoofer. I'm just trying to figure out if the woofer on the AL-III is supposed to be out of phase with the ribbon (and if so, why), or if that's a spec sheet typo?

So I just had my AL-III crossovers rebuilt (Nelion), and I noticed the woofer output was wired out of phase. I asked Greg about this, and he said this is correct and sent me an image of the manual spec (page 10). Sure enough, it shows the woofer out of phase. (This would also explain why my original Audessey setup thought one of my speakers was out of phase and I couldn't at the time understand why.) But it also shows the ribbon input's positive on the top, and the woofer input's positive on the bottom, making me wonder if this could have been a typo? If not, why would the woofer be wired out of phase, and should I keep it wired this way?

Where would I source the caps and pots to rebuild the crossovers?

Where do I start to understand my options on crossover upgrades?

Hi All, My Carver journey started in the early 80s when a friend picked up a C-1 and one of the original Cube amps. I was blown away. I still run vintage Carver around my place and shop, a few M1-01s, a C-1, and a TFM45 in the shop. I'm here now because I have a home theater (Denon x3800h) powering a Sunfire 300x2 I bought new and recently had rebuilt by Greg Nelion, running a pair of AL-III I also bought new 30+ years ago. After all this time the one woofer has started farting on LFEs - probably due to the improved low frequency of the new x3800. So I'm hoping people here can help steer me to how I can best restore my AL-IIIs. New woofers, or just a foam surround replacement? Crossover upgrades while I'm in there? I have a full shop, and so a fair amount of electronics work there, so DYI shouldn't be an issue. Dan
