The B&C 18SW115 18 ″ Professional Subwoofer is a premium high-end loudspeaker suitable for bassists who crave the highest quality sound and build and are more than happy to pay for it. The specs are something else, but that’s to be expected for the price of admission.

It features an oversized 4.5-inch split copper voice coil in a fiberglass former, which is much larger and technically more advanced than any other subwoofer in this review. And on top of that, it features a vented voice coil space that reduces power compression. As well as an aluminum demodulation ring on a pole piece to minimize distortion.

The B&C 18SW115-4 is a top-notch subwoofer that rivals other 18-inch subwoofers with similar functionality. Two unique things I noticed about this subwoofer are that it has a large 4.5-inch voice coil and an aluminum demodulation ring that helps it eliminate distortion. Its ventilated air space along with its neodymium magnet assembly help this subwoofer to significantly reduce power compression. Price was the only downside to this subwoofer. But overall, it has an attractive design, and in terms of performance, this subwoofer won’t let you down.

  • Rockville PBG18 18" 2000 Watt Passive Pro Subwoofer w/ MDF Cabinet and Pole Mount.

  • 2,000 Watts Peak Power. 4" KSV voice coil. 100 oz. woofer magnet. Vented Enclosure for Improved Bass Response.

Rockville also produces excellent audio equipment for use at home and at events. The Rockville PBG18 18-inch Pro Subwoofer is a fully enclosed cabinet subwoofer that offers incredible power at an unbelievable price.

The Rockville PBG18 18-inch Pro is suited for both home speaker systems and live gig setups, which is one of its main selling factors. The ergonomic handles make it easy to transport this sub from gig to gig, and the strong pole mount and rubber feet keep it secure no matter how much power is applied. These qualities are ideal for budding or struggling musicians who will appreciate the versatility of a subwoofer that can be utilized for practice sessions, home listening, and live performances.

When it comes to budget cabinet subwoofers, this subwoofer is our top option since it integrates all of the design elements we expect from high-end models at a quarter of the price. Because the PBG18 is so sensitive, you can get a lot of bass even if you don’t have a high-quality amplifier.

The frequency response of the PBG18 is the only drawback. Because the subwoofer only goes down to 35Hz, you’ll lose out on a lot of the deepest, lowest bass notes found in Hip Hop, Rap, and R&B songs. In addition, midrange notes have a tendency to sound muffled. Fortunately, this is readily remedied with the use of a powerful mixer, which can help to clarify and alter the sound to meet all of your favorite musical genres.
