How it is possible to get “MO” out of a Massive Audio CEA 2031 Certified “SUMMO” subwoofer? All you got a do is just Double Stack 250 Oz Strontium Magnets on a newly designed light weight ultra-strong cast aluminum basket. Use dual 4 Ohm Black 3” anodized VC formers with Kevlar Spunlace suspended into a custom Black Anodized 1 piece milled pole-plate. (This helps increase the concentration of the magnet field) Now just add oversized dual Poly Nomex Spiders. Bond them to Kevlar fiber reinforced Non-Pressed Paper Cones that have been stitched in “Red” onto the oversized surround. Throw in some 10 gage speaker cable that’s hard wired to the tinsel leads and just bolt everything together! That makes the SUMMO 104 "XL", 124 “XL” & the 154 “XL” Extra: “Large, Low and Loud”
