Love the lows from this cabinet
This gives some great lows and you can feel and hear the bass. I needed something that would give lows without running through the main system for worship. We lack subs currently and we had some speaker problems that were distorting the system when I was running from my Ampeg DI box. Nice warm tone, can go muddy if you boost the lows too much though. This cabinet is not suited for styles of music that require a lot of mid range. For that the non-ported designed with the driver might be better suited. The porting on this amp helps the "feel" in the room where bass is concerned. I prefer a more old school deep bass, so this cabinet works well for me with the PF-500 head. Very lightweight, I am glad I purchased this amp and cabinet from Sweetwater. Along with the Fender American Standard Jazz bass and Ampeg SCR-DI box(all Sweetwater purchases with Kevin Spunde), the tones are great for me.
