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.

I normally dont like to be long winded on reviews...but this subwoofer deserves the details. I had never heard of DS18 before looking on amazon. But let me tell you that this sub and the manufacturer has blown me away! I have designed and built audio systems for years , both professionally and for pleasure. So sound quality is very important to me. Being very skeptical about purchasing a subwoofer from a company i had never heard of took alot from me especially being on a tight budget. But i did it and let me tell everyone......i feel like i cheated the manufacturer. This is the cleanest, and loudest entry level subwoofer i have ever heard. Especially in this price range. I paired this single 4ohm sub with the pioneer GM D8701 monoblock amplifier. It is a match made in heaven. Now people....please understand....this is not a competition sub. This sub will not flex your doors. It will not vibrate your mirrors. But it will reproduce bass tones very crisply, deeply, and loudly. I needed a good sub for my single cab Chevy 1500 that wouldnt overpower my aftermarket radio. So i decided on a console design to get the most out of the subwoofer. Before i designed and built my box , i contacted DS18 in miami florida and was immediately connected to a technician named Aaron. He provided me with information not included with the delivered sub to maximize the efficiency of my box design. This turned out to be a huge help. And the customer service there was top notch. After speaking with Aaron i designed my box with a port tune at 38 hz. So far this sub isnt even broken in and i am stunned at the tonal quality and deep rich low bass tones. This subwoofer is very well made and has surpassed any expectation i have of it. This product also has an excellent staff to help answer any question you may have. I was treated with the utmost respect while on the phone with them and after hearing both the sub and their customer service....i am now a hands down fan of their product. As long as you read the specs,use the proper enclosure and pair the right amplifier with this subwoofer....you will not be dissapointed. ... show more

    • These subs aren't quite what's pictured.
Style: 10 inch
The first on; e they sent was damaged in shipping. I suppose it could be fixed, but they were quick to send out a replacement, so big props to them for that. What they DON'T tell you is the fact that the dust cap doesn't really look like how they do in the pics. The "DS18" logo Is embossed but not colored in. It's just the color of the center cap. I'll post pics later. I really liked the red and white logo. I'm really disappointed that the only part with colored in is the little "select" word. I'll let you know how it sounds once installed I guess. 🤷🏼♂️ ... show more

    • Far exceeded my expectations
Style: 12 inch
For around $100 these things are amazing. Did a system for a good friend with 2 12” in a prefab sealed box and I was blown away at how clean the bass is but at how low they can go. Don’t get me wrong it’s nothing like a ported box tuned to 30hz low, but for a sealed box they got lower than similar priced kickers, fosgates, JBL, and other big brand subs I have installed in the same prefab sealed box. These are not cheap knock off no name brand subs, they are far superior to the name brand guys, you can tell just by looking at the surround alone these are better and they back it up with real performance. For $100 sub, they are at the top of the list from my experience. ... show more
