Good price

I bought to replace my 1999 oldsmobile eighty eight stock component speakers. When I purchased I hadn't yet taken off the door panels to look at old speakers, I just used the speaker fit ode here on sonic electronix to find a pair that would fit my car. Well what I didn't realize is that the old tweeters had a very specific bracket which the nvx set did not include. This set of nvx seems to be more towards custom tweeter installs with options to mount flushed or exposed.Anyways, I was worried at first because Id spent long enough deciding what to buy and at this point justwanted to hear the dang things! I ended up using the thickest duct tape I've ever owned to hold me down, and once pressed up against the door they didn't make a rattle or move so it seems to have worked. The woofers on the other hand screwed right in. Overall I am happy with this buy and would recommend them

took a chance

I took a chance on these based on their reviews, i usually would buy a big brand but these seemed legit. I bought these and the nvx 6x9s. After hooking everything up it sounded pretty good but it was just my crappy head unit powering them, so when i bought an amp wow these things came to life. my whole truck is rocking now!

i have recently purchased and installed this kit so i figured a review would be worthy for this.
upon opening the package i couldn't help but be amazed about how much it weighed for just a 5 1/4 component kit. the magnet on the woofers have a lot of weight. the tweeters you can really see the quality in them its really hard to explain just buy a nvx tweeter and you'll see. the cross overs are clearly labeled and make for a really clean install. upon hearing them in action i was blown away the mids sound punchy as heck some times i feel like i have a set of decent ten inch woofers in my door and the tweeters are loud as heck thanks once again sonic and nvx i truly am not ashamed of this purchase.

Great Value and Sound

I put this set in my 83 F-150 with a older Sony 100.2 amp. Sound good, very clear and they make my door mirrors vibrate. I feel I got my money worth and then some. Highly Recommended!!!

Bright, but worthy - especially for the coin

My first impression of this kit is that the tweeters are way too loud and bright. However, using the -3dB attenuation on the crossover helps quite a lot. I discovered that using the swivel in the flush mount option to point the tweeters at the windscreen made a world of difference & did wonders for staging. If your only option is to aim these tweeters on-axis or close to on-axis, you'll want to choose another kit. However if you have the room/configuration to aim them forward, or significantly off-axis, they sound great.

The woofers sound quite good, but really need an amp to get them off their butts. Sound quality is realistic, midbass is present, but not overwhelming...well balanced.

Don't expect to use the included clip nuts as every one I tried snapped in half. I just re-used factory hardware where possible & some drywall screws in my homemade adapter

Other than that, the drivers & crossovers are well-designed and executed & should make most happy - again as long as you amp them & move the tweeters off-axis. Reflected seems best so far with the tweeters. On-axis is too harsh.

I'm still tuning and will be for some time to come, but for the coin, and particularly after re-aiming the tweeters, I'm quite happy with this set. Solid construction, poly cones & butyl surrounds should mean a long, happy life. Considering price (and the huge discounts currently available), these little numbers earn themselves 4 stars.

Great Sound!!!

Great Sound No Doubt! It was tricky to run wires back & forth thru the car to crossover but very worth it at the end! You won’t regret this buy made my Bose system sound pathetic.

Top notch

I had my Doubts about NVX but I can say this is some of the best car audio I have had it is in my opinion very close to JL audio.
