The reason I chose to compare the SW8000 and the LMS4000 is the coil, it's exactly the same between the two. The same can't be said for the LM10D2. Coil and soft parts are the same on the 10" SW8000 and the 10" LMS4000, only difference is the motor. Gaps and top plates are the same between the two motors, the SW is a TC9 and the LMS is a 3LM. Q is much higher on the SW8000.If magnets had the same charge, Q shifts should be minimal, and I'd like to point out that the LMT from the RL-s line has a tc9 top-plate and a qts over 1.00 lol. My Old school TC3LM 4K's have the exact same Q as my tc9 lms drivers

The LM10D2 uses a TC9 but it has more coil density as the Mms will show when compared the the LMS4000. Compliance on the LM10D2 shows this as well, it's stiffer to counteract the added mass. It's also got a higher BL product, again more coil. Can't really compare the two in that regard. Different beasts. More like the new offerings than it is the LMS4000.
