[QUOTE="Papermaker85, post: 8508939, member: 572595"] A street beat woofer that sounds great at a good price. Unfortunately part of the design requires a large toplate to get the proper strength because of the coil windings/build. So it's not excatly cheap but really like this design Over the others I built.. The original design aspect was to get inductance as low as I could have a good amount of throw and the power handling to reach those levels of excursion. 100% of the coil in the gap it's about 25 millimeters x max.. at 70% it's around 34 millimeters x max but it's really designed to stay Within about 90% of the coil in the gap(ruffly 28-29mm) to keep the BL curve flat as possible. I chose not to use shorting rings because it's will substantially lower bl. I might end up doing a magnetic Id shorting ring but it actually sounds great as is.. In short to simple answer your question is it's built to be high Excursion, low distortion and high output driver. we missed the target moving Mass but I actually have plenty of BL for the mass and 1w/1m efficiency after broken and is about 88 DB which is actually pretty decent for such a high throw driver.
