NVX NSP4 - Open Box, Great

Great value and awsome sound.

After purchasing a DSP for my stereo project, I decided to add a center channel. These speakers were the perfect size to fit in the center 4 x 10 factory speaker hole. I didn't need the bass response of a 4 x 10 (along with having an extra 4 x 10 speaker that I would not use), so I mounted 2 of the NVX NSP4's in an adapter plate that used the existing mounting holes for the 4 x 10 speaker. I was able to use a heat gun to remove the tweeter covers so they would not interfere with the factory grill cover. These are a perfect fit for that center opening and provide excellent sound quality for the center stage. Instruments and vocals sound clear and not bright, thanks to the soft dome tweeter.

NVX 4 inch door speakers

I’m absolutely in love with these speakers, they will make you go deaf with the right setup I’m running 4 of these speakers on a 4 channel 400watt Rockford Fasgate amp and a entry level c10 sub on another amp with all my speakers wired to my amp using oxygen free copper wiring and these speakers are so crisp, the only issue I had was buying open box and one of the speakers I could tell had been pushed way to hard before the break in period was over and it blew the second day but that’s the risks of taking the open box discount on these speakers, overall 8/10 because of that mishap.

Great speakers for the price

The speakers are very good quality right out of the box. I installed these to replace some old aftermarket speakers. These sounded way better right away. They have a great balance sound. They have perfect highs and good lows for the speaker size. Can't expect much lows from a 4" speaker. These do put out more low than expected.
