These are the best in the market definitely will buy again from ds18
The tweets I put in brings it all together. Affordable with quality sound.
Just installed in my ultra classic and couldn't be happier. Great sound and very loud. Will definitely be buying another set for the lowers.
A1+all hands up
These are the best tweeters I’ve come across in a very long time.
Fits well!!! Looks good!!! Priced well!!! Performs as expected. The only thing I would change applies to all the DS18 products that have RGB Chasing LEDs in them. Change the wire coloring from Red (12V+) Black (12v-) White (Data) to either Red Black Green , Red Black Yellow, or Red White Green. Having the data wire in white can make it confusing when adding to an LED setup. It would be more inline with the normal practices.
Overall great sound quality and improved my sounds tremendously from a voice perspective it elevated it to a differnt level will definitely recommend to others!
Love the way it works and easy to install
Delivery was fast, and showed up on time. Very powerful amp, and so far the best amp I have ever had. Make sure you have the proper electrical system to power this monster. Haven't had any problems with it so far. Definitely will be buying 2 of the hool-x15.1 dhe
high excursion subwoofer to try them out as well
I replaced a skar 100.4 with this one and my speakers came alive, love this amp and also very small
These speakers are beautifully made and sound awesome! Very loud and clear and the LED lighting is the perfect touch.
Popped right into my factory speaker slot! Great quality gives you that organized clean look your heart desires 🤣
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.
Very simple to install and everything is self explanatory
