Recently, we reviewed the Axiom M3 v2 bookshelf speakers and found them to be great speaker for the price point but bookshelf speakers are only capable of reproducing the higher areas of the sonic spectrum.
Bookshelf speaker based audio systems require a subwoofer to produce the lower frequency ranges that the bookshelf speakers cannot accurate reproduce. Axiom produces a subwoofer which is said to be an excellent match sonically for the M3 speakers.
