So, for several years now, my Eden Metro has been sitting around. I bought it new as a '98 model which means it puts out 200 @ 8ohms, 400 @ 4ohms, and 600 @ 2ohms. The issue was that I started to do a lot more doubling between a 4-string Spector and a 5-string NS Design CR-5M upright. Both instruments sound amazing and I hardly every use much EQ if any on the amp (only for room correction). Where the issue came in is with the upright and the thump. For a while, I combated this with a variable high pass filter, but I haven't had much luck finding one that doesn't color the plucking and playing with a bow. Regardless, I stopped using the combo years back because it couldn't keep up with the outside gigs as the headliner in Va. Beach (outdoor amphitheaters). So, I've been playing/toying with, much like many of us, trying to come up with various modular setups for various venues. In this research, I came across the Faital speakers and the light went off. Some questions: What if I replaced my 10" speakers in my Metro with 4ohm Faital versions wired in series for 2ohms? If I didn't run a crossover for the 10s, but did run to the stock crossover for the stock horn in series, what would happen to the horn? Am I off base thinking that it would be just fine? Any issue still using the attenuator? How do some of the Faital speakers compare to the original Eden's (I always thought the Edens were a little harsh due to a spike I'm guessing around 1.2k, not to mention they can't handle much excursion or X-Max)? Is the Metro cabinet (essentially a 210XLT) with ports at the top and bottom, acceptable for the volume (space) required for the Faital speakers? Which Faital 10" speakers would someone suggest? Any help is greatly appreciated. Thanks.
