Active audio SB110 Commercial Indoor Subwoofer

Introduction

The SB110 subwoofer is designed to extend the bass response of column loudspeakers Ray-On. It is passive, has no filter, and therefore requires filtering upstream of the amplifier
SB110 is very compact and can be positioned both horizontally and vertically for optimal visual integration.
The high-end 10-inch loudspeaker is loaded with an enclosure operating in interactive dual volume mode. It achieves a remarkably low cut-off in a small volume, while yielding sharp and dynamic sound.
The SB110 also exist in 70/100V version under the reference SB110T.
The SB110 subwoofer can be used for background and foreground music, audiovisual programs, small live, in :

• Meeting and conference rooms
• Amphitheaters
• Places of worship

Requirements and installation

We recommended that the SB110 be positioned far enough away from the audience, so that the sound coverage is uniform over the entire audience. The distance separating the SB110 from the closest listeners must be greater than the reverberation distance. Thus, practically speaking, the SB110 must be placed at least 3 meters from the closest audience members. The SB110 can be placed to the ceiling to if necessary.
In terms of maximum sound level, the SB110 is designed to be aligned Ray-On column loudspeakers. To maximize the power of the column loudspeakers, we recommend:

• As many SB110 as there are R210
• 1 SB110 for 2 R110

When several SB110 are used to deliver the same signal, theoretically 3dB efficiency and SPL may be gained by positioning them together (e.g. side by side or one on top of the other). The maximum sound level obtained with two adjacent SB110s will then be 6dB greater than that obtained with a single SB110. On the other hand, the sound coverage may be more uniform if they are distributed around the room.
The SB110T is equipped with a 100V line transformer with a power of 100W. Its maximum sound level is therefore lower than that of the SB110 (about 8dB less). The low cut-off of the transformer is 35Hz.
The SB110 can be placed horizontally on the floor, or vertically against a wall using the accessory SB110_KMV (figure 1).

Wiring

For SB110, use 2 x 1,5mm² cable when the distance between the amplifier and the SB110 is less than 50m: 2 x 2,5mm² for greater distances.
For SB110T, use a 2 x 0,75mm² cable (minimum).
The SB110 / SB110T connector can be used to connect several subwoofers in daisy chain configuration as shown in figure 2. This naturally presupposes that a suitable amplifier is used. Thus, for N subs connected to the amplifier a daisy chain configuration:

• In 100V mode: amplifier power ≥ N x 100W
• In low impedance mode: the amplifier must withstand a load impedance of 8/N Ohms and must deliver sufficient maximum power.

Recommended equalization

Table 1 gives the recommended equalization and crossover settings for the SB110 used with Ray-On column loudspeakers. The corresponding response curves are given in figure 3.

Excursion limitation

High-amplitude signals with very low frequencies cause large membrane excursion. Excessive excursion causes harmonic distortion, which degrades the sound quality and causes a risk of damage to the loudspeaker.
It is desirable to limit the amplitude of the deflections either by reducing the amplitude of the applied signal or by placing a high pass filter upstream of the amplifier, for example, a second order Butterworth at 80Hz.

Warranty

The SB110 has a 5-year warranty, in accordance with the General Conditions of Sale. Malfunction problems must be reported to the manufacturer prior to any return.

Troubleshooting

Decrease the bass level by decreasing the gain and/or adding a high-pass filter (see above “Equalization”)

Presence of unwanted vibrations| Objects are vibrating in the room due to the effect of low frequencies emitted by the SB110| Identify and secure the objects that are vibrating
