  • This has excellent strong tight clean bass as far as hard hitting punch goes, but as far a low end subbing,it needs more power, it can create the sound very well but can't force it out strong enough for my tast.klips 600 watt can shake the walls ,floors and be heard two houses away, but it lack tight punchy bass like high pitch bass.JustWantTheBest
