Overall 3.5 out of 5 stars (3.5 / 5)

These were my first component speaker set. I got them for around $90, and for that price they are great. The oversized 6.75″ woofers deliver decent low end performance, and the big silk dome tweeters deliver natural sounding highs with a relatively low crossover point. The crossover has a -3dB setting to quiet the tweeter some (and you need it).

If you are looking for a low cost set of decent components, definitely add these to your list.

Sound Quality 3.5 out of 5 stars (3.5 / 5)

I give the sound quality a 3.5/5 since the bass response wasn’t like I was expecting based on other reviews. I know they aren’t going to be like mini subs in the door, but they still lacked a little.

The tweeters are super bright. I like my sound pretty flat with a little bit of bass added and a gradual roll off on the high end. They had some pretty harsh peaks around 4-5k Hz but probably mostly due to my ~45° off-axis installation. The crossover has a switch to turn the tweeter down -3dB which helps, but you will still need some sort of EQ to keep your ears from bleeding.

Even with these “problems” the speakers don’t sound bad, especially for this price. With a good processor and EQ I’m sure you could dial them in pretty nicely.

Value 4.5 out of 5 stars (4.5 / 5)

Despite the subpar SQ, the value of this component set is great. The parts are very well designed and look nice. That combined with the ~$100 price means great value with these.

Features 4.5 out of 5 stars (4.5 / 5)

These speakers come with everything you need for installation: screws, spacers, 5×7/6×8 adapter plates, at least three tweeter mounting options, and a punch out on the box for tracing a cutout for custom installations. They also have the tweeter attenuation option on the crossover.

Design 4 out of 5 stars (4 / 5)

The woofer is beautiful with its bronzish colored woven fiber cone. It has a big magnet and sturdy basket. Very solid speaker.

The tweeters aren’t too bad looking, but I think they can be better. The tweeters have wave guides to control sound dispersion and widen the sound stage, but they are huge and because they are so big, you don’t have many mounting options which is why I had to mount mine so far off-axis.

The crossovers are nice looking. They are a bit on the big side, but I have definitely seen bigger. They do their job and look good doing it.
