[QUOTE="ciaonzo, post: 6443922, member: 607015"] Again, I'll have to kindly disagree with you on various points. The first being, the measurement for the OD on the slugs of a 3HP and a TC-9. They're the same, approximately 7.5" in diameter. I'll have some photos up a bit later to help others see what we're discussing. Second, I just checked PE and didn't come up with any listing for a REVO LMS. Only one at the moment is the 10" LMS which uses a TC-9. A REVO is a REVO because of the coil it uses in conjunction with a TC-9, same goes for the LMS. They have very different BL, sensitivity, power handling, suspension, etc... However, I have heard the same talk of an LMS REVO but I'm assuming it would just be the same thing as is currently offered; a TC-9 based LMS driver. Last, would be the idea that the need for the fourth slug in the 3HP is needed for a longer coil. The coil used in the TC-9 LMS and the LMS 4000 are identical in every way, all measurements. I have verified 3+" of excursion in the TC-9 version (1" slugs) without bottoming the coil. In fact, the extra slug is to help offset the low sensitivity and lower the Qes/Qts by raising B product.
