[QUOTE="Trancer, post: 7652063, member: 544448"] Its from their new baking process. They also switched up the coil material for lower distortion, as mentioned above. There are many factors that come in to play on why on a few TC lines have black coils. Kyle over at TC Sounds answered a question that was the exact same one as yours, in the TCSounds message board, but I cant find the question and answer Here is what is new with the LMS-R. Couple of these new features are why the coils appear to be black. Lower distortion stainless steel formers on all drivers* REVO gets replaced with the LMS-R that uses a new 6-layer LMS coil.* New shorting rings for TC9, 4HP and 3HP motors (LMS-R, 5400 and Axis) New detachable feature for all drivers (expect epic) New detach feature is much more accurate than older methods. Drivers with the detach feature get shipped in two boxes to ensure trouble/damage free shipping [URL="http://www.tcsounds.com/forums/index.php?/topic/2-new-tc-product-information/"]http://www.tcsounds.com/forums/index.php?/topic/2-new-tc-product-information/[/URL] LMS-R 12 Qts 0.43 Total Q Qes 0.46 Electrical Q Qms 6.7 Mechanical Q Fs 28 Hertz, Free Air Resonance Res 3.96 Ohms, DC resistance Ls 4.7 H, series inductance Lp 7.7 H, lossy series inductance Rp 5.1 Ohms, loss across Lp Dia 250m meters, effective Vas 39 liters, air volume equivalent mms 280 grams, effective mass cms 115 um/N, compliance bl 20.5 T*m, motor strength SplSens 84.5dB SPL max @1W absorbed Geometric Stroke 24.1 Millimeters, (voice coil - gap) / 2 70% BL 29.4 Millimeters, BL is 0.7 original value (one way) Xmech 39.4 Mechanical displacement limit (one way) Long Term Power 1000 Watts Program Power 4000 Watts, short term peak power limit [/QUOTE]
