[QUOTE="Electrodynamic, post: 3739379, member: 548723"] A measured 25/26mm Xmax 8" woofer would have a basket with similar mechanical clearances of the 8W7. You can get by with making the motor shorter with a linear BL optimized motor, but traditional methods would yield a motor with similar depth as the 8W7. The JL 8W7 is a fantastic driver (albeit, it's a $300 8" woofer) and it throws a TON for a little 8. The Treo doing 1.3x more linear travel (and even MORE mechanical travel) than the 8W7 with [B]much[/B] less clearance isn't going to happen. There are a few frames out there that will support +20mm of one-way linear travel for an 8" frame (keep in mind that mechanical travel is even more), but they all require custom tooled surrounds at the least (and some require custom spiders). Flat-out, with the 4-spoke Venezuela and a standard 2" voice coil, that driver will not do anywhere near 26mm one-way linear. [/QUOTE]
