Great upgrade speakers!
I installed four of these in my wife's Mercury Mountaineer to replace the factory speakers The sound is much better than the factory set and actually sound as good or better than any other 6x8's I have ever heard. Bass response is pretty good and clean for rock and country music and the tweeter sounds great, nice and crisp as it should be. Overall I am very happy with the sound and performance. I would buy these again without a second thought in the future for factory replacements and even on a small amp. I have these running directly off of a Soundstream VR-650B head unit.

Great for the price
I recently installed four of these in my 94 mazda with an Alpine head unit and they sound as good if not better than speakers I've payed double for. The bass response is surprising for only running off my head unit and the highs are nice and crisp. The vocal frequency is where these speakers really stand out. I would by the N series from NVX again and again. simply a great speaker at an absurdly low price.

Great Backfill
I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

THESE SPEAKERS FLAT OUT ROCK !
My experience with Sonic Electronix has been excellent ! The NVX product line is a fantastic value and the performance rivals products 3 times the cost.
For 3.5in speakers these things are amazingly loud. Awesome mids and tweeters that will blow your mind. The front staging in my audio system is better than I ever could imagine due to the fantastic performance from these speakers. Top notch build quality and materials, for $30 they are a super value. I am buying another pair to run in my rear deck. I will say it again
