1. Introduction

Thank You for purchasing Tannoy PowerDual™ iQ i8B.

The iQ 18B is a dedicated sub-woofer designed for high definition sound reinforcement at low frequencies. It comprises an 18” driver in a horn-loaded cabinet, giving increased efficiency and improved LF output.

For optimal performance, the iQ 18B has been designed to operate in conjunction with the iQ 10 mid/high horn-loaded cabinet, where the system is controlled by a dedicated loudspeaker management system TDX2.

The cabinet is constructed from high quality 18mm birch plywood, featuring handles for easier transportation, convenient M8 flying points and a pole-mount stand socket that serves as a base for locating the iQ 10 mid/high speakers in the air.

2. Unpacking

Every Tannoy iQ 18B is carefully tested and inspected before packing. After unpacking, please inspect your iQ 18B for any damage sustained during transit. In the unlikely event of any damage, would you please notify your dealer immediately and retain your shipping carton, as your dealer may ask the faulty unit to be returned for inspection.

3. Connectors/Cabling

The iQ 18B is fitted with two 4-pole Speakon™ connectors. Speakon™ has the following advantages over EP and XLR type connectors: All terminations are solderless, making life easier at the time of installation or when field servicing is required. Contacts will accept 6 sq. mm wire with an outside diameter of up to 15 mm and a current rating of 30 Amps.

The pins of the two Speakon™ sockets, marked input/output on the rear of the speaker, are paralleled within the enclosure.

Tannoy has adopted the following wiring standard for iQ 18B: -

Cable choice consists mainly of selecting the correct cross sectional area in relation to the cable length and the load impedance. A small cross sectional area would increase the cables series resistance, inducing power loss and response variations (damping factor).

Connectors should be wired with a minimum of 2.5 sq. mm (12 gauge) cable. This will be perfectly satisfactory under normal conditions. In the case of very long cable runs the wire size should exceed this, refer to the following table for guidance: -
