LCS v.2 Series 300W DVC Subwoofer

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. The refreshed v.2 update was released in 2020 and added an all new, custom tooled frame, push terminals, a rubber mounting gasket, and upgraded tinsel leads.

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.

    Costomer service and quality

    Posted by Gabriel Alvarado on 11th Jul 2020

    First off I'd like to say the costomer service is excellent! Second the subwoofer at just 89 bucks sounds rediculous. My first sundown sub definitely not the last. Easily handles more than 300 watts and pounds. I love it. Thanks CAB and apex
