Hey guys, the Model XL is getting closer. We should receive the revised front panels from the machine shop this week. We are trying to have them brushed and anodized as well so we can get some better product photos going. Possibly laser etched as well, time permitting. Then we can test and tune with the new stiffer panel. We didn't realize that six 140mm woofers could make so much sound pressure! Combined, they do have the cone area of two 10 inch woofers, but with 6 channels of amplification on them. I can tell you it did over 120dB on the audiocontrol sa3052 and the bass sounds very tight and quick, not sloppy and muddy. Thank you for being patient while we perfect this beast.
