Simply amazing! Entry level?

The following review is for NSP65KIT, which is a part of the bundle you are viewing.

I can not believe these are considered entry level speakers. I am picky and these sound really great for their price point. The mid-bass is spot on, and blended really well with my 10" subwoofer. When it comes to tweeters, they’re super smooth and very clear, not harsh or ear piercing at all. If you are looking for an incredible sounding set of components without the big price tag look no further.

Don't go without it

The following review is for SDBSK2, which is a part of the bundle you are viewing.

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

Solid speakers for the money

The following review is for NSP65KIT, which is a part of the bundle you are viewing.

Got these for my old Prius to have some better speakers than stock. Running them on an old Alpine MRP-F300. They perform pretty well thus far. Handle power good and can pack a decent punch. I think once they're broken in they will sound even better. The tweeters leave some to be desired. At certain frequencies they don't sound the best, but these are budget speakers so I cant complain. These aren't audiophile quality but they will make an old system sound better than stock for sure.

NVX SDBSK2 Premium Stealth Black

The following review is for SDBSK2, which is a part of the bundle you are viewing.

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.
