    • Summertime Block Party
Style: 3.5-Inches
Unfortunately I had to return because they did not fit my Polaris Slingshot, but i an a true fan of DS18; sound quality is second to none. The power is top notch and built great! You will get what you pay for,whether a noise ticket or a great concert. The look is sleek and the price is ranged for quality. Cons: seller are good to work with as 3rd party but if you need support be prepared to sing, dance and pay with dealing with ds18 warranties and customer service &support. 1yr for 3rd party and 2yrs directly from ds18. Not trying to take from anyone's pocket but buy direct if you can or buy here for faster delivery. ... show more

These speakers slap when it comes to the sound. Quality is great. Only downside was the mounting holes in my dash are slightly bigger. Made it work with an adapter. Very clear and hit every note.

    • Replaced my dash speaker in 2019 accord Hybrid touring with 10 speaker system
Style: 3.5-Inches
Replaced my dash speaker in 2019 accord Hybrid touring 10 speaker system. The original was so bad I couldn't recognize who was singing, Siri would speak through that speaker. I replaced it with an infinity true 4ohm speaker, not knowing it was a 3.3 to 3.5 ohm speaker. It triggered a fault and so I could never hear Siri. The original was 4.4 ohms DC measured. This is the closest match I could find at 4.2 ohms. The original lacks a twitter and is full range so this was a good match. After 1 week so far so good, I hear Siri again. ... show more

    • Fit perfectly into a 2018 Mustang GT w/9 speaker system
Style: 3.5-Inches
It is as if they are made for the stock 3.5" speaker brackets. You will need to drill the 4 holes for the screws since the mounting points are not the same as the stock stuff, but there is enough material in the stock brackets that you can just drill small holes and the speaker will screw in without a hassle. I was even able to reuse the wires that came off of the stock speaker plug so i didn't need to cut any wires on the harness side. You will have to cut off the speaker wires from the speaker, but if you ever wanted to return it to stock you can just buy the stock speakers with the brackets used from somewhere out there, I'm sure. Just make sure you run some felt or foam tape around the edges and over the screws, so they don't vibrate against the door panel. Now sound quality wise, these are far, far better than the stock stuff. They output really nice subtle treble and have far better midrange sound than the stock speakers the stock speakers totally blow out the upper midrange, but these tone it down to perfection. I prefer these over the infinity reference speakers I had before mainly because the treble isn't super blown out because these don't have a tweeter on them, so the highs are quieter, which is fine since there is a tweeter nearby in the a-pillar to make up for that. Really happy with these and if you're also looking for an upgrade over stock that isn't going to snap your wallet in half, get these things. Oh, and I'm running these from the stock amp/head unit. ... show more
