6.25 speakers

The 5.25 speakers are among the most popular ones after the 6.5, 6 x8, 6 x9, 5x 7.  The distinct difference is obviously in their sizes but the big question is why chose one over the  other?

For the purpose of clarification, we will try and explain  why you should go for one size over the other.

The size of the woofer is the most important component in a speaker. A  bigger woofer is better because it performs exceptionally well especially in low frequency reproduction situations. This does not mean that  smaller speakers don’t perform as good as the bigger ones. On the contrary, there are smaller speakers with as much sensitivity and great performance and sound quality.

We have reviewed some of the best  5.25 speakers . We will be telling you what they offer and why you should buy them.
