“Rockville is proud to introduce the all new PBG18 18” professional subwoofer. This latest addition to our bass gig series is our most powerful and best quality passive subwoofer to date. We tested these against subwoofers from leading brands in the industry such as Peavey, Yamaha, and others and these held their own! Please do not compare this to any off brand name subs. This subwoofer is commercial grade. The advantages of purchasing Rockville, Yamaha, Peavey, or other high end brands are longevity, power, sound quality, and sensitivity. We did so much testing. There is a huge difference between the quality and components of this versus off brand names.

The off brand enclosures are built with a material called particle board. We spend more money manufacturing these with MDF, which will hold up for a much longer time than particle board. Better quality wood also equals better sound! The pro audio subwoofer in the cabinet has a very large 4″ KSV voice coil and a 100 oz. high quality magnet. The off brand names models will usually have a magnet half the size and a voice coil half the size as well.
The advantage is that our unit can handle more power and will last longer. These subs can take a real beating! Another thing we wanted to focus on is the sensitivity. When we were doing all our testing we noticed with the same amplifier, one subwoofer we were testing against went louder than the rest. The reason was because it had a better sensitivity rating. This means that it was more sensitive to amplifier power.
Another major factor that effects the sound is frequency response. Our model sounded more musical than some of the famous brands we tested it against. One sub we tested would make our ceiling rattle a lot just because it had a very deep tone. The problem was it was not musical. Our model hits those same deep tones when it is supposed to, but also has the ability to hit some mid-low tones that this other sub was not hitting.
