About: Sundown Audio LCS-12 v.2 12" 300W RMS Car Subwoofer - Dual 4 Ohm
Since their introduction in 2017 the Sundown LCS series woofers have been known for their impressive bass response and high levels of dependability. Typical entry level woofers are highly limited in terms of linear excursion, mechanical ruggedness, and thermal performance – these are all aspects that we have taken to the next level in the Sundown LCS series.
A double stacked magnet structure and an extremely long voice coil allow us to achieve a class-leading linear x-max of 14mm one-way in addition to high mechanical clearances (over 2” peak-to-peak). The large coil combined with gap venting, chamfered pole-piece design, and optimized pole vent give the LCS Series impressive thermal performance. Mechanical stability and durability are addressed via the strong paper cone, rugged foam surround, and a high quality spider with fully tied-on tinsel leads. All major areas of woofer durability have been addressed to the maximum level possible in this category.
Bottom-line; if you are looking for a great subwoofer option and you have a tight budget the Sundown LCS Series woofers are for you. These woofers have absolutely no frills – simply raw performance for the dollar. When it comes to the perfect combination of power, deep bass, and affordability, look no further than the Sundown LCS subs. As the creators of the loudest subs on Earth, Sundown knows bass best! The Sundown LCS woofers are known for their impressive bass response and high dependability. Typical entry-level woofers are limited in terms of excursion, mechanical ruggedness, and thermal performance. The v.2 update added an all-new, custom-tooled frame, push terminals, a rubber mounting gasket, and upgraded tinsel leads.
