TSB-212

The TSB-212 is a general purpose band-pass subwoofer designed to add low frequency reinforcement to Turbosound loudspeakers from the IMPACT, TCS, TXD, and TQ ranges.

It utilises two very high excursion 12” low frequency drivers connected in parallel to give a combined impedance of 4 ohms. These drivers are housed in a 15mm (5/8”) birch plywood enclosure with stacking feet, multiple M10 internal rigging points and a perforated steel grille. Input and link connections are provided via a pair of Speakon NL4 connector located on a recessed panel at the rear of the cabinet.

Amplifier considerations

Turbosound speaker enclosures should be driven by high quality power amplifiers designed for true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and well designed cooling systems for reliability. Turbosound power amplifiers such as the T-45 and T- 25 are recommended for this purpose.

The program power listed in the loudspeaker’s technical specification is the best guide to the size of amplifier required for general purpose applications. The amplifier should therefore be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at the loudspeaker’s stated nominal impedance. This approach allows sufficient headroom to generate good dynamic range.

In general, the more powerful the amplifier, the better it will sound, provided that it is not driven into sustained clipping. It should be understood that overdriving an insufficiently powered amplifier is more likely to cause loudspeaker damage – the total energy in a heavily clipped signal is far higher than in an unclipped signal – than operating a more powerful amplifier within its ratings.

RECOMMENDED AMPLIFIER POWER RATINGS:

The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, per

channel) should be equal to the program power handling of the

loudspeaker at its nominal impedance.

The TSB-212 is rated at 800 watts r.m.s., 1600 watts program and the impedance is 4 ohms. It should be used with an amplifier capable of delivering long term power of 1600 watts at 4 ohms.

Crossovers

The TSB-212 should be used with a professional quality external electronic crossover providing a 24dB/octave low-pass filter at 125Hz and a 24dB/octave high-pass Butterworth filter at 30Hz, and limiting functions. Turbosound LMS series loudspeaker management systems are recommended for this purpose.
