  • 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.

Love these speaker
I gotta say for the price I was a little skeptical but after installing them and running them fit a few weeks now they are truly underrated. I’m running a 2800w kicker amp mono block. Speaks are hooked up Parallel. For 2 10s in my crew can Silverado it is insane amount of deep bass. Great speakers for the price. Also there is now way they are rated at 300w. I’ve thrown 2800w at it all no with no problems. I had to add an extra battery because of the bass and power draw even with 0 gage wire. ... show more

Make sure you have the air volume.
I know sundown was high quality but it was better than I thought. The power is rated conservatively and gets plenty loud. Not to mention the look of it as well the fact that is durable as can be.

One of the best brands of speakers
They are sundown's... what more could you ask for. We found them half off and couldn't say no. Sound quality is great... No distortion.. Great bass range.

Sound good on a budget.
Paired to a Phoenix Gold RX2 1000. I listen to metal so I don’t need more than heavy punch, and something g that can keep up with blast beat kick drum. Does the job well.
