Description

The Adastra HD20V is a heavy duty round horn speaker built for voice alerts and public address across outdoor and indoor areas. It uses a spun aluminium flare with a weatherproof ABS rear cover and reflex cone, so it holds up well in demanding settings. A fibreglass compression driver sits behind the flare, giving clear speech output where it matters most.

Inside, the driver connects to a 100V line transformer via a 4-core cable, offering three power tappings so you can set the output to suit the space. The horn is rated IP66 for water and dust resistance and has been tested from -55°C right up to +70°C, which makes it a sensible choice for industrial installations and exposed sites. Nominal impedance is 8 Ohms with the transformer bypassed, and the frequency response runs from 400Hz to 5kHz, a range that suits announcements and paging rather than music.

A tilt-adjustable wall bracket comes as part of the package, so you can angle the horn towards the listening area during fitting. The finish is RAL7042 grey, which keeps it discreet against most walls and structures. If you need dependable, consistent performance in almost any environment, from car parks and loading bays to factory floors, the HD20V is a straightforward option to specify. Note that horn speakers are sometimes called horn loudspeakers, and the two terms mean the same thing here.

Frequently Asked

Is the HD20V suitable for outdoor use?

Yes. It carries an IP66 rating for water and dust resistance and has been tested from -55°C to +70°C, so it works well outdoors and in exposed industrial sites.

What power tappings are available?

The 100V transformer offers three different power tappings via the 4-core cable, letting you set the output level to match the area you are covering.

Can I use this on a low impedance amplifier?

It is designed for 100V line systems. With the transformer bypassed the nominal impedance is 8 Ohms, but for most installations you will run it on the 100V line.

Does it come with a mounting bracket?

Yes. A tilt-adjustable wall bracket is included, so you can angle the horn towards the listening area during installation.

Is it good for playing music?

The frequency response of 400Hz to 5kHz is aimed at speech, voice alerts and paging rather than music playback.
