Let customers speak for us
from 3889 reviewsI have been looking for a 2 ohm speaker for my set up foud this one and l love it sounds really good and takes a ton of power

These evl 12s are where it’s at..build the box to specs like it says..hardest hitting subs I’ve bought to date

sound great look good even though you can’t see them in my truck

Fit & finish is very good bought them for my saddle bags on my 2000 road king installed your amp also combined with these speakers Wow very happy with the sound & performance $ well spent if I choose to add any more speakers I will definitely go with Ds18 in the future TY

Alot of sound for something small love it

Best loudspeakers🔥

I previously purchased a JBL rally bar 36 inch and was highly disappointed so I reached out to Anthony at DS 18 directly. He hooked me up with a set of 8 inch tower speakers 500 W he gave me a matching amp that I needed and a head unit, their customer service, especially Anthony walked me through the whole process of tuning my amp And system. It was so loud that we had to un bridge and just hook it up to 2 Channels Way more than I ever expected to get.the JBL rally bar. I couldn’t even hear the music over the motor running in the background very pleased with the product couldn’t be happier

Wanted to add more power to my mids. Great bit and works great

You will not believe how these tweeters sound .... Dont let the price fool you

nice quality material work well and great purchase

I got 2 6.5 up front and 2 6x9 in my lids in the rear of my 24 road glide police edition. The sound great! The sound quality is top notch. I wanna run some 8 inch subs in my bags to give me more bass. Ds18 hook me up so I can do a sound video on YouTube with my guy baggers and burban. Lol

Good Quality affordable Price
