Overall 4.5 out of 5 stars (4.5 / 5)

In my opinion, this is one of the best sounding set of speakers out there for this price. Great low end bass notes for a speaker this size and a natural sounding tweeter that isn’t too bright (although I still prefer the -3 dB setting). They are also not that deep so aren’t hard to fit most factory speaker locations. The crossovers are bi-ampable, too for even more control of your setup.

If you are looking for high quality and high power sound for less than $300, these are for you.

In fact, these speakers are so good, I have them in my personal vehicle.

Sound Quality 4.5 out of 5 stars (4.5 / 5)

First thing you notice with these is the bass response. For such a normal looking 6.5″ speaker, these put out a lot of low end, not earth shattering or even comparable to a subwoofer obviously, but for a speaker in this price range, it’s pretty impressive. 

The tweeter is nice and natural sounding and not too bright or overly harsh. It’s also pretty small compared to some component sets or even the older model of these speakers.

Overall, these speakers sound great even without any EQ or external processing. Everything sounds nice and clear without any crazy peaks in the frequency response.

Value 5 out of 5 stars (5 / 5)

I would say the sound you get out of these speakers is comparable to many $300+ sets. The value is great and they even have bi-ampable crossovers.

Features 5 out of 5 stars (5 / 5)

These speakers come with everything you need for installation: screws, grills, a few different tweeter mounting options. They also have the tweeter attenuation option on the bi-ampable crossover.

Bi-amping a crossover is awesome if you have an extra pair of channels on your amp and especially if you have time alignment. This allows you to run the passive crossovers and time align the tweeter separately from the woofer. Or if you don’t have time alignment, you can use this feature to adjust the woofer gain separately from the tweeter for even more midbass. This alone adds a ton of value and features to this set.

Design 4 out of 5 stars (4 / 5)

The woofer is pretty basic looking with a decent size magnet. Don’t let this fool you though.

The tweeters are also pretty basic looking, but once again don’t let this put you off.

Sticking with the theme of basic, the crossovers also don’t look like anything special. Just a decent sized black rectangle with woofer/tweeter inputs and outputs.
