Happy Customer

I have ordered a few things from DS18. I have their equipment in my motorcycle and I am enjoying it. I had an issue with one speaker that didn’t work but I was able to get online and get a replacement sent under warranty. Fast shipping.

Great for the money

Bought these, a bit skeptical with no personal experience and have nothing but good things to say. Would buy again!

Fit my 14 Harley Street Glide perfectly and sound excellent

Amazing speakers

I have a set of these speakers on my Harley and they sound great. Can hear music crystal clear at high speeds. Also water resistant so I don’t have to worry about them getting wet in the rain.

Awesome

Fast shipping, Great sounding speaker, very loud, and Easy installation.

Compact and powerful

It's compact and fits perfectly packed away in my inner fairing. Packs a nice punch. Running all DS18 speakers, sounds like a live band riding with me on my 2014 Street Glide. Works fine with my stock head unit.

ZR 4-Channel Class D Amplifier 4 x 400 Watts Rms @ 4-ohm

Best shallow mounting sub

Put these in my ram 1500 under the rear seats, I don’t have much space, these bump. Great travel/clean cut base/they look nice. Currently have them hooked up to a 800x1 kicker amp on a low setting for break in and am going to put in ds18’s 2500x1 amp, they can take a lot of abuse, personally I’d say best shallow mounting sub for the money, I’ve been thru a few! Hit like there a big magnet deep mounting sub!

I love these 4 inch tweeters

I love them they sound great along with the looks I have to say that I don't agree with the filters that they come with I feel that they do distort a little bit and so I gotten the 4.7uf 100v and that cleaned them up Alot on clarity the ones that come with these tweeters are 4.7 UF 250v if you change them to the ones I have you won't be disappointed these tweeters perform beautiful highs I have the paired with my pro x 6.5 witch I'm planning to get another pair of the mids in future !

Oh yeah.

There was a break-in time, maybe 15 minutes, but after that they have sounded great, a nice clear bottom to the sound.
