Peavey 21 inch Passive Subwoofer

Peavey 21 inch Passive Subwoofer
Buy on Amazon

For a low asking price, peavey 21 inch passive subwoofer has managed to overwhelm their customers by packing as many features as they could. If you power the PV 118 with a good 300 w rms amplifier it would be an excellent companion to the two SP2 speakers, providing those speakers are powered by 300 w anplifiers. It is designed to drive another pv115 (non-powered) speaker, not a subwoofer. It has a dedicated sub power amp with crossover and will integrate nicely with your PV115D.

These subwoofers are passive, meaning they require an amplifier. The sound is very audiable and it makes you appreciate good music. This is also built well with solid corner protectors and grill. The size amp for these speakers is pretty much up to you and how much bass you want them to produce. It is perfect for a DJ looking for bottoms.

Why We Like This:
  • Very good live instrumental bass response, but not too "punchy" for recorded playback
  • Good looking sub, black carpet, nice sturdy metal grille, metal handles
  • Good brand reputation

Cerwin-Vega 21 inch Passive Subwoofer

Cerwin-Vega 21 inch Passive Subwoofer
Buy on Amazon

Compared with other subwoofer in this category, the cerwin-vega 21 inch passive subwoofer has a convenient design. The CVi-218S (Contra-Sub) is a portable, dual eighteen inch dedicated subwoofer system designed to extend and supplement the low frequency extension of CVi full range systems in live music and playback applications. It features two high power, cast frame eighteen inch transducers with 3" voice coils for extended use during high spl applications. It allows the two drivers to work together in the same acoustic space to reduce distortion components caused by driver mechanical non-linearity when the system is driven at high levels.

These are used for (bass) low end of a sound system. Steel handles and pole mount cup are also featured for use as a base for pole mounted full range systems. It is cleaner, smoother low frequency reinforcement at higher spl levels.

Why We Like This:
  • One of the new comers and featured product
  • New and hot release
