Wall loudspeakers: features, model overview, wall mounting

It only seems that wall loudspeakers Is something outdated and suitable only for the filming of a historical film. In fact, this is a completely modern and practical solution that has its own important features. But besides an overview of the models and their practical characteristics, it is equally important to know the answer to another question - what kind of fastener is better to take on the wall and how to use it.

It is quite predictable that a wall-mounted loudspeaker is used mainly in enclosed spaces. It is usually used where ceiling systems cannot be installed for some reason. Most often, loudspeakers of the diffuser electrodynamic type are mounted on the wall. This core element is surrounded by a specially designed housing that protects the delicate electronics while enhancing its appearance. If the designers have worked hard on the design, it will look attractive in any room. The main stream of acoustic waves will be directed parallel to the floor. Wall mounted units are great for:

• educational institution;

• shopping center;

• industrial facility;

• warehouse;

• office complex.

Model has attractive characteristics IWS-03A. It is a modern and convenient 3W loudspeaker with an internal attenuator. The connection to the lines for 70 or 100 V is structurally implemented. The power control is well thought out. The connection to the line is made through the mediating terminal box using the screw method.

Main technical parameters of IWS-03AI / IWS-03AB:

• total acoustic power 3 or 2 W, respectively;

• sensitivity not lower than 89 dB;

• maximum sensitivity level 94 dB;

• body made of plastic and fabric;

• coloring, respectively, in ivory or black;

• net weight 1.2 kg;

• dimensions 0.18x0.31x0.11 m.

Another model with an attenuator with a total power of 3 W is SWS-03A from the manufacturer Inter-M. Connection to 70 or 100 V transmission lines is possible. The technical properties are as follows:

• electrical resistance 3300 Ohm;

• sensitivity level from 89 to 94 dB;

• working off frequencies from 150 to 12000 Hz;

• ivory coloring;

• execution of the body made of fabric and plastic;

• net weight 1.24 kg;

• linear dimensions 0.183x0.268x0.116 m.

When this power is not enough, it is worth paying attention to PASystem EVA-20. The sound intensity of this speaker can even reach 20W, which is great for large spaces. The sound pressure is up to 103 dB. It is possible to connect only to broadcasting channels with a voltage of 100 V.

The compact device can also be considered a good alternative. Apart Kubo3T-BL. The 3-inch wide-range speaker does its best. The connection to both 70 or 100 V lines and low-impedance broadcasting channels is structurally implemented. The outer casing is made of mechanically resistant ABS plastic. The included bracket in the form of a Latin letter U allows you to adjust the sound angle from 0 to 140 degrees for wall and ceiling mounting.

Other important parameters are:

• speaker with steel protective grill;

• frequency reproduction from 94 to 20,000 Hz;

• sound pressure limit 101 dB;

• bass reflex housing;

• thoughtful design;

• use of removable panels.

An excellent example of a 10W loudspeaker is the model "Verb-H2-10"... This is a new generation of products from the well-established manufacturer Trombone. The official description emphasizes the optimal suitability of the device for broadcasting radio broadcasts, announcements and warning messages in critical situations. The deviations of the real frequency response from those laid down by the designers do not exceed 3 dB. Operation in the fire detector mode is allowed.

Basic properties:

• reduced power modes (3 and 5 W);

• weight 1.21 kg;

• dimensions 0.26x0.185x0.12 m;

• level of electrical protection IP40;

• sound pressure level up to 105 dB;

• plastic case.

This question is no less important than the selection of a suitable model. Installation is usually done at a height of 2-3 m above floor level (if only there is such a possibility). At the same time, installation is allowed not only on the walls, but also on the supporting columns of the building... Most often, the bracket included in the delivery set is first mounted, and only then it comes to the device itself. The brackets can be made with your own hands, but then you will have to use a welding machine, and perhaps also drill the speaker.

The corners for work are selected according to the size of the speaker system... Chipboard sheets are chosen in the same way. The corners sometimes have to be adjusted to exact dimensions and sanded. After marking the necessary holes on the wall and in metal parts, they drill the channels. Having screwed the corners, they mount the loudspeaker itself. Whether to install a shelf under it - you need to decide on your own.

It is not recommended to use other types of fasteners due to their low reliability. It is advisable to hang the speakers upside down with a slight tilt. Then the sound will be directed exactly in the right direction, and not somewhere to the ceiling. The heaviest loudspeakers are mounted on square or rectangular welded steel tube frames. Sanding and thorough painting will help to improve the appearance.
