Description: 2XL, the winning car subwoofer model in Lightning Lab's inventory of car subwoofers. A beefy 12-inch subwoofer that is capable of outputting a sheer 1000 watt RMS of music power! And be able to handle up to 2000w on its peak. The newer version 2XL's has the ribbed rubber surround which makes the subwoofer driver more durable and can withstand heavy bass bumping in the long run. If you have the same subwoofers, then watch and enjoy. In this episode, we will measure every electro-mechanical and physical data of the Lightning Lab 2XL 12 inch dual 2 Ohm car subwoofer. Thiele-small parameters or t/s p in short, data which professionals and amateurs needed designing in building DIY car audio subwoofer enclosures. So watch and take down notes or perhaps bookmark this video for your preference in your future builds using this mighty fine 2XL sub. TIMELINE: 00:00 - Unboxing 00:35 - How heavy is the sub on the weighing scale. 01:05 - Using Dayton Audio DATS v3 in measuring impedance (AC). Measuring each individual coil, in parallel and in series. Detecting also Vas and Mms. These parameters are significant in designing and building enclosures using software like Bass Box Pro, WinISD and Bassta! 02:45 - Measuring subwoofer physical dimensions. Displayed in Metric and Imperial systems. All these data are needed in calculating the subwoofer driver's displacement. Subwoofers are mostly wired in PARALLEL to get the most power out of them so here's the exported data from Data Audio Test System DATS in the parallel setting is what matters. D 260 [mm] Re 1.155 [Ohms] Fs 41.45 [Hz] Zm 16.21 [Ohms] BL 10.74 [N/A] Qms 7.736 Qes 0.5938 Qts 0.5515 Vas 25.66 [liters] L10k 0.5854 [mH] n0 0.2935 [%] dBSPL 86.78 [1W/1m] Ms 227.4 [grams] Cms 0.065 [mm/N] REVIEW: - Factory packaging is top notch. You literally have to open 3 boxes to get the subwoofer out. Box in a box, within a box and into another box per se. - Each voice coil parameters, inductance, impedance is just as equal to the other one. Very much identical to each other. Meaning: they perform the very same level of power and limit. - Reasonably priced compared against Category 7 1K XMAX subwoofer. A 5,000 peso difference is very much! I think that's all for this Thiele/small parameter measurement and short review. Please let me know what you think and you can ask questions by commenting down in the comment section. Watch out for the box video build using the paint and carpet combo style very soon. Thank you all and have a nice weekend.
