[QUOTE="THATpurpleKUSH, post: 7715081, member: 615398"] Well for starters the ED's come in d2 and d4 and the Infinitys only come in s4. The Infinity has slightly less motor force and xmax and a higher fs. I wonder about low end performance because all the other Infinity Ref subs have a low tune for the recommended box, but the 8 has an fb of 40hz. I wonder if thats to impress noobs or for warranty purposes or what. The ED's only have a 1 1/2in voice coil vs 2in on the Infinity HEre are tsps for the Infinity since the site isnt working: VOICE COIL DC RESISTANCE: REVC (OHMS) . . . . . . 3.30 VOICE COIL INDUCTANCE @ 1 KHZ: LEVC (MH) . . . . . . . 2.31 DRIVER RADIATING AREA: SD (IN2) . . . . . . . . 33.17 SD (M2) . . . . . . . 214.00 MOTOR FORCE FACTOR: BL . . . . . . . . 12.56 COMPLIANCE VOLUME: VAS (FT3) . . . . . . . . 0.54 VAS (LITERS) . . . . . 15.23 SUSPENSION COMPLIANCE: CMS (μM/N) . . . . 232.70 MOVING MASS, AIR LOAD: M MS(GRAMS). . . . 124.20 MOVING MASS, DIAPHRAGM: MMD (GRAMS) . . . 122.40 FREE-AIR RESONANCE: FS (HZ) . . . . . . . . 29.60 MECHANICAL Q: QMS . . . . . . . . . . . 6.10 ELECTRICAL Q: QES . . . . . . . . . . . 0.483 TOTAL Q: QTS . . . . . . . . . . . . 0.45 MAGNETIC-GAP HEIGHT: HAG (IN) . . . . . . . . .0.315 HAG (MM) . . . . . . . . 8.00 VOICE COIL HEIGHT: HVC (IN) .. . . . . . . . . 1.34 HVC (MM) . . . . . . . . . . . 34 MAXIMUM EXCURSION: XMAX (IN) . . . . . . . 0.513 XMAX (MM) . . . . . . 13.00 [/QUOTE]
