Maximising Bass with a BK Subwoofer

If rumbling bass sends you to audio heaven, the BK Electronics range is wide enough to suit your existing technology. You’ll find compact options that fit your cabinet easily, yet still provide the subtlety you need in a small room. You’ll also find BK subwoofer products powerful enough for outdoor usage. BK Double Gem review sites list offerings that make the most of limited floor space without skimping on the power you need in an open plan home.

When should you choose a powered or passive BK subwoofer?

If you’re adding to an existing sound system, a passive subwoofer will draw power from your external BK Electronics amplifier. Low-frequency output requires extra power. While you can connect your sub to your receiver, it won’t necessarily have enough power for bass effects.

  • If you’re providing audio in a small room, you can often connect a passive subwoofer to your receiver without draining your amplifier.
  • The BK Electronics P12-300SB is a powered, passive model that can produce booming sound through an amplifier. This works well for large spaces.
  • If you need an active subwoofer, the BK Electronics XXLS400 will reduce signal path crossover without the need for a separate amplifier.
  • An actively powered sub tends to have better dynamic range, clarity, and bass extension.
What role do ports, enclosures, and passive radiators play?

Subs such as the BK Gemini MK2 have sealed enclosures. Those with an extra port and unsealed box improve bass response, while those with a passive radiator improve efficiency via an extra speaker. The BK P12-300SB subwoofer, for example, has a sealed box that produces a dynamic, deep sound.

  • Passive radiators reinforce bass output without requiring a massive amplifier.
  • Downward firing passive radiators send bass towards the floor, while front firing offerings target ear level.
  • Ported subwoofers often produce loose, deep bass.
  • Ported options add to tuning flexibility.
Which specifications produce distortion?

Any BK subwoofer review will communicate a different collection of audio preferences. Some prefer the BK subwoofer XLS200 for its versatility and compact size, while others prefer the analogue-like audio of the XXLS400DF. Ultimately, subs are subject to individual taste, but distortion must always be avoided.

  • Frequency responses under 20Hz might produce clarity, but deep tones require more power if they’re to avoid distortion.
  • Never choose a sub that you intend to play to its maximum capacity. This will create distortion.
  • Wattage of 1,200 or more offers improved bass tone resolutions.
  • Connecting multiple subwoofers in series can reduce clarity.
  • If you prefer deep tones, look for downward-firing subs with increased bass extension.
