PRESONUS DEFIES GRAVITY

27 January 2014

Following last year’s release of the Eris and Sceptre ranges of studio monitors, it’s no surprise to see Presonus releasing a matching subwoofer. The Temblor T10 subwoofer features a 10-inch glass-composite woofer driven by 250 watts of Class AB power, a front-firing bass-reflex acoustic port, optimised resonance-suppressing internal bracing, plus internal damping and a heat sink. The end result of all this is a frequency response from 20 Hz to 130 Hz. Inputs include left and right, balanced XLR, 6.5mm TRS and unbalanced RCA main connectors. Outputs are the same except there’s no RCA, but you do get an extra subwoofer output for connecting a second T10. Input gain and lowpass filter are continuously variable, but the highpass filter to the main monitors is a switch at 80Hz. A clever idea – the T10 has a momentary footswitch (included) that bypasses the subwoofer, highpass filter, and Sub Out. This allows the audio source signal to pass directly through the Temblor T10 to the full-range studio monitors with the obvious benefit of letting you compare your mix with and without subharmonic frequencies. The T10 weighs in at nearly 18kg so you might want to think carefully about placement, although the subwoofer features “gravity-calibrated” rubber feet for stable placement. Presonus makes no effort to explain this further at www.presonus.com or perhaps the lads at Baton Rouge are just having a laugh? All the other tech specs are there.
