I installed them on my 22 Street glide and it blows the other known motorcycle brand away. From now on DS18 will be my go to brand.
Best speakers I’ve ever bought 🤙
I have tried several brands of speakers on my Harley , and these are HANDS DOWN the best sounding , clarity , bass all around amazing !! The customer service from DS18 is above and beyond as well !! I will never run anything else besides DS18
I have the 6.5 in the fairing and 6x9 in my bag lids. It was a fosgate kit. The 4 speakers from ds18 really make this thing come alive. All required some minor modifications to make fit. But a dremmel is all you will need. Amazing sound, build quality appears to be great. Try them and you will be a ds18 believer too.
Threw four of these in a 1969 stingray convertible corvette firing forward from the compartment behind the seats. I researched hundreds of speakers and brands and eventually landed on these. My initial thought is that they were a bit pricey amongst the competitors, but the speaker parameters, especially the decibel rating had me convinced i at least needed to give these a shot. I knew i needed something that was going to be significantly loud for a convertible muscle car and I am here to tell you these speakers blew me away and are the nicest sounding 6x9's I have ever heard. They are slightly underpowered as i have them on a JL 400, 4 channel amp but even still i could not be more happy. I also decided to run one DS18s 6.5" subs in a ported box and the balance of sound is everything I wanted for this car.
Pictured: the box has 3 separate compartments total, in the middle is 1.6-1.7ish cu ft. box ported to DS18s manual specs. on each side of it are two 6x9's per compartment. The fit was so incredibly tight i barely got the 6x9's to fit, they are actually mounted to some of the outer edges of the box instead of the baffle. Didn't have any carpeting so i just went with a basic spray paint.
I am pretty sure i am a sold out DS18 fan at this point, I will be recommending their products from now on and can't wait to start outfitting my other vehicles with DS18 gear.
