Let customers speak for us
from 3738 reviewsloud n clear

I have a high-end set of separates in the front of my vehicle, but the stock crossovers didn't work for my install. 150W per door. High-quality Class AB amp. 2 Ohm Woofer, 4 Ohm Tweeter. I bought another brand, but there was too much insertion loss and the clarity suffered.
I researched these units and found nothing but great reviews. The larger diameter inductor wire definitely was key to a lower ESR and I got all the power back that I was missing. 3dB more volume at a minimum and a higher quality sound.
The mids sound a lot more open and the mid-bass is more punchy. Crisp highs as well. There is more detail in the music. I might need to use the -3dB padded output for the Tweeter. Impressive performance all round.
Thanks for the great x-overs!

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.

It’s not just me, as I approach my home my neighbors are dancing in the street. The sound of music coming from my Jeep, crystal clear & carries beautifully.

The speakers we got were plenty loud, we had no problem hearing them over the sound of our side by side

Lots of power, super loud and crisp. Make sure you have an amp strong enough to push these. Amazing 10/10 have no complaints.

Sounds great . So worth it

Crazy loud
but WE LIKE IT LOUD

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!

Great amp

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 !

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

Had 1 speaker out of the 4 ordered come damaged. Emailed DS-18 and they sent me a free replacement, great customer service, fast responses. Will definitely be ordering more from them!

Sounds great loud and I like loud

Nice speakers
