Tannoy SUB-12-I Brochure

Definition Install DS12i sub

Product Description

The Definition Install DS12i sub has been designed to underpin a Definition install theatre

or media room system with truly remarkable low frequency performance. Massively

constructed around 300mm (12.00”) professional drive unit, this subwoofer will produce the

ultimate soundtrack experience, with spectacular and thunderous bass, yet still be agile

enough to maintain finer musical detail with precision and speed.

This 38 litre direct radiating design is robustly constructed MDF enclosure, using 15mm

(0.62”) for the panels and 36mm (1.41”) for the front baffle. Extensive internal bracing

minimises panel resonance ensuring a tight and responsive bass performance. Capable of

achieving 38Hz and with a sensitivity of 94dB (1W = 2.83V for 8 Ohms), the DS12i sub will

deliver an SPL of 126dB peak. Recommended amplifier power is 400 – 800W @ 8 Ohms.

Finished in rugged textured black paint, the enclosure is fitted with two binding posts, eight

M10 inserts and four rubber feet.

The DS12i sub is compact enough to bring class leading performance to a wide range of

installation applications; from media rooms to home theatre and boardrooms through to

high end marine interiors.
