These new top of the line Reference Series Subs can stack to become line arrays and individually can dig as low as 15Hz at powers up to 1000watts.  

The REL No.31 and No.32 Reference Series Subs are serious about their looks and performance with an equally serious budget.

This new reference range are both based on a sealed box design with long throw front-firing drivers made from carbon fiber cones with inverted center caps. The No. 31 features a 12″ driver and a 900watt class D power amplifier, while the No. 32 features a 15″ driver and a 1000 watt class D power amplifier. Both of these drivers boasting a 4″ stroke.

The class D amplification is supported with level control, dual parametric filters, variable crossover control from 20 to 90 Hz and a switchable phase control, 0 or 180 degrees. 

Both models rear panel connectivity includes; high-level Neutrik speakOn, low-level stereo RCA, and XLR, LFE RCA, and Line XLR inputs together with high-level Neutrik speakOn, LFE XLR, and line XLR outputs.

Remote control of both models is provided for with a small circular palm sized remote that provides in-seat access to; crossover frequency, parametric EQ, hi/low-level control and phase.

These reference subs are physically substantial. The No.31 weighs in at 114.5 lbs and measures 435x638x724mm (WxHxD), while the No.32 tips the scales at 187 lbs measuring 540x743x816mm (WxHxD). Size does matter, with the No.31 going down to 17Hz (-6dB) and the No.32 hitting 15Hz (-6dB). The No.31 is finished in high gloss black while the No.32 comes in piano black lacquer. 

Have a large room or do you just want to go above and beyond those THX levels? Then stack up to five of these beauties for some real shake, rattle and role using the REL Couplers. These milled solid aluminum feet bolt to a sub and together with sets of rails enable the creation of a sturdy bass line array.
