Key Features

Double 10 inch Passive Radiator Enclosures 2400 Watts - In Phase PR210

A speaker enclosure using a passive radiator usually contains an 'active', or main driver, and a 'passive radiator' . The active driver is a regular driver, and the passive is typically the same or similar, but without a voice coil or magnet assembly. It is only a suspended cone, not attached to a voice coil or electrical circuit.

Passive radiators are used instead of a reflex port for much the same reasons - to tune the small volume and driver for better low frequency performance improved power handling and sound quality. They are also used to eliminate port turbulence and reduce motion compression caused by high velocity airflow in small ports. Passive radiators are tuned by mass variations, changing the way their compliance interacts with motion of the air in the box.

InPhase PR210 Features
  • Driver 2 x 10'
  • Impedance 4 Ohm
  • Sensitivity 91 dB
  • Peak Power 2400W
  • Frequency response 30-200Hz
  • Dimension (H x W x D): 452mm x 595mm x 290mm

Best Box i have ever heard!
JAY on 07/04/2017 5 star rating

brought this last week, OMG! i have had bassboxes all my life, but this has to smash them all to bits!totally Banging!

I recently purchased the inphase pr210 twin 10" subwoofer box from the Leicester branch. i am running this with a ipa1601 amplifier and my gosh its loud! the beauty behind this is its fairly compact for 2 subwoofers so give me more space in my boot than most other set ups, and it still performs outstandingly. Grate product with exceptional service!!

I fitted one of these to my 3er Compact to replace a Vibe CBR active double 12" box. Running it off an IPX1200 and IPC2.4N and it sounds fantastic-follows the bass in my rock/indie music much better than the vibes, drops just as well as the vibes and takes up less boot space. Girlfirend and I both love the tasteful styling:)
