Skar Audio NDX33-ST | 3.3" High Compression Neodymium Super Tweeters - Pair.

These tweeters are amazing and crispy clear. Before getting the ndx33-st I was looking 4 something that I can crank the volume up a little more and so after doing my research between different name brands I saw that these tweeters had more sensitivity than the rest of the other name brands so I tried it out and I just loved it. Definitely get these tweeters you will never be disappointed. I currently have just one pair of the ndx33-st and three 6.5in. Midrange on a chuchero in the back seat of my sienna and they are super super loud. If I keep on cranking it too high I think my eardrums are going to pop. I love it.

I love the sound quality for the price but...

I really think it’s dumb to try and get a straight answer from your employees and or members of the Skar family. It’s sad that the only way I can express this belief is through a rating on one of your products. Thanks.

Great quality really improved my system

Running these skar tweeters
Alpine head unit
Jl audio c2650
Jl audio c2 690
Alpine type r 12d4
Alpine 800 watt mono
Jl audio digital amp 125x4 channel

These tweeters have been a great addition to my system and I chose these tweeters over alpine or jl audio for there pricing the material used and after I heard them wow the sound it’s clear and really brings in sounds I wasn’t hearing before very musical definitely did a x10 to my system quality

Skar ndx33-st

These things crank. I’ve been installing systems for 16 years and just heard about skar last year and after running two 18” evls I fell in love. These tweeters are super clear and loud! They also offer recones on the site which I haven’t needed but definitely a bonus. I can’t wait to hook up my dnr 15 now and hear that thing. If your questioning buying them.... don’t. They are excellently built backed behind excellent customer service. They are a must have!!!!
