Description

DS18 SLC8s Subwoofer SeriesThe Select Series Subwoofer come in 8", 10", 12" in a black steel basket. DS18 understands the demands of its entry level customers car audiophiles and fisically responsible deal-finders. The subwoofers' successfuly relies in their ability to deliver better quality and RMS power than all other entry level offerings of their competition.Break Your Subwoofer InA new subwoofer must go through a short but important process of 'break-in' before it is run under harsh conditions. The 'break-in' process will ensure the subwoofer is able to perform as it has been designed to. Over- driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance.Surround FoamUnlike rubber, foam is an alternative for the surround in speakers and subwoofers. Foam is in general more flexible than rubber, giving the woofer a slightly higher efficiency. This also translates to better excursion.

    • The price is right for a powerful speaker

These speakers have a lot of power and you can’t beat the price for a quality speaker

Okay, I installed it this morning. Breaking it in slowly. I installed it in a ported enclosure. Definitely rattled the windows and mirrors but not as much sound as I would like. So I covered the port up. Definitely improved the sound quality. I listen to classic rock. It Does take more power than my previous speaker. I bought one of those $20 Boss speakers. And it would bottom out even at a medium volume. This does not seem to do that. Speaker Grill does not fit because of the giant foam roll. Definitely sticks out a lot more then previous speaker.! I think it was worth $46 +. If anything changes I'll update but I think we're good to go. I can recommend it for just your average stereo. Oh, I'm using MTX Road Thunder 202 amp bridged. Which is 200 Max Amps and 100 RMS. And the gain is at about 40%. Update after a week. Quite impressed with the sound! I've had to turn the gain down on the amplifier because it got louder as it got broken in and loosened up. Resealed this subwoofer box. That also helped a lot. Totally recommend it. Great for an average to above-average sound system.! Update 2 weeks so far. The sound is amazing. I have it in small sealed box. I really can't get over how good it sounds. If i really turn up the bass it will rattle my truck apart i think. ... show more

    • Worth the money.
Style: 8 inch
Not a bad little sub for the price. I have it in a sealed enclosure but honestly think this would work great with a ported.

    • Works perfect!
Style: 8 inch
This sub was perfect for what i wanted it for & sounded amazing after I finally got done. I had a old 2011 sony stereo & the connector pins broke off inside the head unit. So i bought some terminals & plugs, then did a bit of soldering & cutting, wired up the the new sub with the old speaker box.... & boom everything worked perfect. Sounded great & got much bass than the factory sub that came with the system. The material its made with is looks top notch. But the only downside which is no big deal to me at all is the weight of the whole sub. Its a bit heavier than what i thought but hey im not complaining, eveything turned out great! ... show more

    • Great budget Subs
Style: 8 inch
Bought these as a gift for my son, we installed in a sealed "trunk" style box. (.51 cubic feet per) We have them running through a Pioneer 900w 2 channel amp @4ohms and they sound great. (Great response, crisp) These were a great alternative to the DS18 Elite 8" subs I have. Entry level price point and requires WAY less amp to run them. They really fill in the bottom end, respond to lower frequencies than you would expect. ... show more
