I ended up going with the second 15 STL array and its a killer tone. I did not need more volume but i did need a second speaker cause I couldnt get certain higher frequency stuff to cut through especially fx. The second 15 makes it sound so full and punchy! I also was able to turn down the overall volume a lot adding the second cab. So now I have the Magellan 800 with 2 15" STL ARRY cabs. I am still learning how to eq it all with my basses and pedals cause its so touchy but I love it. I cant wait to get back out there an play. I am sure no one in my area is really using Genzler stuff YET! so itll be amazing to see their faces once they hear what these cabs and amps can do!! anyone else running the 2 15"? any eq tips welcome! I seem to have my jazz bass tone locked. The spector has so much low end, its a little tougher to dial in. Its the 5 string Euro Lx darkglass preamp inside.
