Powerful lowering in little space One of the advantages of the 6.5" subwoofers is the sound quality, even in ported boxes it offers you a much more precise, controlled lowering and with notes that in a larger diameter subwoofer are lost, you don't need to be an audio engineer to notice the difference.
