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 over-sized 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”
