110 SERIES SUBWOOFERS AND INPUT MODULES  
This manual is intended for the owner, operator or installer of Tannoy 110 Series Subwoofers. It is a guide for installing,  
setting up and operating the 110 Series in accordance with established codes and practices available at the time of publication.  
It does not and can not detail all possible mounting or wire configurations. The end user is advised to retain the advice and  
services of a qualified contractor who is familiar with local codes and trained in the installation of Tannoy professional audio  
systems.  
The 110 family of subwoofers has been engineered to deliver low frequency extension and impact from a concealed ceiling  
mounted position.  
The 110 series subwoofers feature a 10” long excursion driver capable of low end response down to 31 Hz and power  
handling in excess of 100 Watts. Its design is fully complementary to any Tannoy full range wall or ceiling mount loudspeaker.  
Two different subwoofer cabinet designs and five different input “modules” offer a wide range of combinations that can meet  
almost any installation challenge, and fit into any indoor environment.  
Today’s sound reinforcement systems - whether in commercial or institutional environments - must handle program material  
that demands high impact, high fidelity audio reproduction. At the same time, they must be nearly invisible. The Tannoy 110  
Series of subwoofers meet all of these criteria without compromise.  
CABINET OPTIONS  
110TB (TILE BRIDGE) CABINET  
Simple yet sophisticated, the 110TB is the first product of its kind: a true ceiling mounted  
subwoofer. Engineered to deliver low frequency extension (-3dB @ 31 Hz) and impact  
from a concealed ceiling mounted position, the 110TB integrates almost invisibly into  
any indoor environment by using a standard air handling vent cover as a speaker grille.  
The easy to install 110TB drops seamlessly into a 2’ x 2’ ceiling tile without any special  
construction requirements. Each corner of the cabinet is fitted with a seismic tether  
point. This system can also be flown in free space via 3/8” threaded rod, chain or aircraft  
cable. Fire rating is NFPA class A. Whether your application calls for low level warmth  
or high SPL slam, the 110TB provides the required punch.  
110SR (SHEET ROCK) CABINET  
The second in the Tannoy family of true ceiling mounted subwoofers, the 110SR is  
engineered to deliver low frequency extension (-3dB @ 31 Hz) and impact from a  
concealed position. It is specifically designed for flush mount in sheet rock ceilings,  
walls, overhangs or any position offering adequate clearance and suitable structural  
support. The 110SR features seismic tether points, and safe and secure installation  
with a sturdy pre-installation ring. The pre-installation ring is available separately for  
new construction where the sheet rock installers are in ahead of the contractor. A unique  
benefit of the 110SR is that it remains serviceable, and fully removable, from the ground  
after installation by simply removing the low profile grille. Fire rating is NFPA class A.

INPUT MODULE OPTIONS  
PASSIVE (STANDARD)  
The basic connection panel supplied with any of the 110 Series Subwoofers is a 6 Ohm speaker level input via barrier strip.  
It is highly recommended that the audio signal be lo pass filtered via an outboard active crossover. This input module is ideal  
for systems requiring several subs that share a common outboard crossover and amplifier.  
PASSIVE 110 INPUT MODULE  
MADE IN CANADA  
LO PASS FILTER  
Speaker level inputs and outputs via barrier strip are passively filtered 100 Hz 12dB/octave LO pass for the subwoofer,  
making this the ideal system for value and simplicity. The total impedance load of the satellite speaker(s) and subwoofer  
should not be less than the minimum specified for your amplifier. Long wire runs to and from this module need to be an  
appropriate gauge of speaker grade wire to retain proper damping and signal transfer characteristics.  
LO-PASS  
100Hz  
PASSIVE 110 INPUT MODULE

PASSIVE 70 VOLT (Passive 70 Volt available for either option of passive units)  
A 70 Volt distribution amplifier is capable of supplying power to a number of remote speakers without concern of long cable  
runs or varied impedance loads (limited to the amplifier power and line load). The passive 70 Volt module takes advantage  
of this type of installation with a 150 Watt interface transformer, definitely placing this 70 Volt unit above the “wimpy” crowd.

ACTIVE (ACTIVE SUBWOOFER WITH 2-CHANNEL FEED-THROUGH)  
A dedicated power amplifier that really brings your 110 Series Subwoofer to life. Balanced line level inputs with switchable,  
balanced 80 Hz high-pass feed through’s provide appropriate signals to your satellite speaker’s amplifier. An auto stand-  
by feature automatically switches power on and off in response to an audio signal. A full complement of signal conditioning  
controls rounds out this very versatile controller (See Active Module Controls for complete information). The Active input  
module is UL and CSA listed.

ACTIVE INPUT MODULE CONTROLS  
1) INPUT - Two channel (stereo) balanced line level input. Connect via XLR male plugs from your signal source.Use high quality 2  
conductor shielded audio cable ( Belden 8451) for runs of up to 200’. The XLR pinout is: pin 1 (shield), pin 2 (signal high), pin 3 (signal  
low).  
2) HIGH PASS OUTPUT - Two channel line balanced output (male XLR) filtered of frequencies below 80 Hz (12 dB/octave). Connects  
to your amplifier for driving full range satellites speakers. Use high quality 2-conductor shielded audio cable ( Belden 8451). The XLR  
pin-out is pin 1 (shield), pin 2 (signal high), pin 3 (signal low).  
3) POWER MODE - Select AUTO-ON for automatic power-up in the presence of an audio signal. In this mode, the unit will revert to stand-  
by after an audio silence of 15 minutes. Switch to OFF to remove power from the unit. Power OFF will also disable the signal to the HIGH  
PASS OUTPUT.  
4) PHASE - Subwoofer phase may be switched to 0 or 180 degrees to match the phase of your full range drivers. The switch is in the  
correct position when the system exhibits an increase in LF output when switched at a sustained level. NOTE: be sure all full range  
loudspeakers are wired in common phase during installation.  
5) LF BOOST - Adjusts up to 4 dB boost at frequencies below 60 Hz for a more dramatic low end performance.  
6) EARTH LIFT - Switches the internal ground connection from chassis to “floating” to help eliminate any possible ground-loops that may  
cause hum or buzzing in the subwoofer or other pieces of gear.  
7) X-OVER Mode - The LO PASS position is used in most installations. ALL PASS presents a full range signal to the subwoofer. The ALL  
PASS mode allows the user to defeat the built-in LO PASS circuit, which may be useful in certain situations where an external crossover  
or processor is used.  
8) X-OVER FREQ - Used to adjust the LO PASS frequency of the subwoofer. This control only adjusts the signal going to the subwoofer  
as the HIGH PASS crossover frequency is fixed at 80 Hz. (Satellite speakers with limited low end response may require a higher crossover  
frequency for the subwoofer). This control is best adjusted by ear using a high quality signal.  
9) SUB LEVEL - Used to adjust the gain of the subwoofer amplifier without affecting the HIGH PASS output.  
OPTIONAL J-BOX - If you prefer to hard wire your installation directly into conduit via a J-Box,  
please specify with your order.

MECHANICAL INSTALLATION 110TB  
NEW / EXISTING CONSTRUCTION INSTALLATION PROCEDURES:  
Before you begin:  
Please read and understand all of these instructions thoroughly before beginning any work.  
Note that construction work for the installation of all Tannoy products must be done to local building codes by qualified,  
licensed installers. A local building inspector should approve any overhead installations. Tannoy assumes no liability for  
cause and effect of improper installation work.  
Your package includes:  
The 110TB ceiling subwoofer is complete with rubber isolation grid around the grille perimeter to drop neatly into a properly  
secured 2’ x 2’ ceiling grid without vibration or resonance.  
Additional considerations:  
Survey your site and choose installation locations. At this point, you may choose to suspend the subwoofer in free space  
or in a 2’ space x 2’ space dropped ceiling grid installation.  
Parts / tools required: (Installation dependant)  
• Hanger Bolts (Fig. 1.) These can be purchased for installation into wood or metal, for example, with a Hilti™ power fastening  
system.  
• Coupling nuts and backing nuts (Figs. 2 & 3).  
• Threaded rod (Fig. 4).  
• Turnbuckles (Fig. 5.).  
• Wire rope, wire rope nuts, thimbles, chain, quick links (Figs. 5 & 6).  
• Wire grid tiles (Fig. 8).  
Note: For 2’ space x 2’ space tile bridge drop in, you will require wire grid support tiles on each of the four corners of the  
grid immediately beside the subwoofer. This is usually accomplished by means of the same wire support tie used to support  
the grid and for lighting fixtures etc...  
IT IS IMPORTANT TO ALWAYS TETHER THE SUBWOOFER SECURELY TO THE BUILDINGS PERMANENT STRUCTURE  
USING CHAIN (Fig. 9) OR WIRE ROPE. THIS IS THE SEISMIC TETHER POINT.  
The list above is a suggested selection of parts only; what you require will depend on your suspension method and physical  
location.  
The 110TB is supplied with four 3/8” closed eyebolts already attached. When suspending in free space, it is recommended  
that you use the same size hangers, nuts, rods and fittings; alternatively, if you are using wire rope, 1/8” rope and fittings  
are the smallest you should consider.

MECHANICAL INSTALLATION 110TB  
2’ x 2’ Tile grid installation procedures:  
1)  
2)  
The 110TB was designed for quick and simple installation directly into a 2’ x 2’ T-bar ceiling grid (Figs. 9 & 10).  
Remove several tiles around the installation location to gain easier access for placing the subwoofer in the ceiling  
grid.  
3)  
Be certain that there is sufficient hanger wire suspending the grid where you intend to install the subwoofer. If not,  
it may be necessary to add additional grid hanger wires around the perimeter of the location, as required. We  
recommend a minimum of four per sub location, located on the main grid support bar within four inches of each of  
the four corners of the subwoofer.  
4)  
Using wire rope or chain, select opposing corners on the subwoofer to connect safety lines, or seismic tethers (Fig.  
8 & 9) securely to the structure. These lines should be taut enough to support the majority of the weight of the 110TB,  
yet leave enough load against the ceiling grid to prevent the grid from buzzing. Be sure all tether points are securely  
fastened to the subwoofer and anchored securely to the substructure of the building.  
Free space installation procedures:  
1)  
2)  
3)  
For an installation in free space, select a location that will allow suspension from directly above the subwoofer. Begin  
by measuring a 19.5” square, and at each corner install a fastener (Fig. 11 & 12) such as the recommended hanger  
bolt to support each corner of the subwoofer.  
Thread a coupling nut all the way over a hanger bolt and with a 9/16” socket set, start threading the hanger bolt  
into the support structure. Secure a hanger to a substructure at all four corners. This may be accomplished several  
ways depending on your particular installation.  
Back off the coupling nut completely (Fig. 11) and thread on a backing nut with which to lock threads to the coupler.  
Hold the coupler up to the hanger bold to estimate the half way point of the coupler and set the backing nut to that  
height before re-installing the coupler and tightening it in place with a socket and an open end wrench. Thread a  
backing nut onto the threaded rod (or an eyebolt) far enough so the rod can be threaded into the coupler until it  
stops, having reached the hanger bolt inside. Now tighten up the backing nut on the rod to secure it from turning,  
until it looks like (Fig. 4). Remember that the rod could otherwise be an eyebolt, if you are using the wire rope  
suspension method, or a Hilti™ type fastener. Be sure to follow local building codes.  
4)  
Always install and utilize all four points and it should look like (Fig. 13). In this photo, the turnbuckles have been  
added to the ends of the rods. The closed eyebolt on the turnbuckle has been removed and replaced with the  
threaded rod. Note that the turnbuckle is stamped with an “L” to identify the load or live end. Observe the correct  
assembly procedure from rod to eye-hook.  
5)  
6)  
Now it is a fairly simple procedure to place the subwoofer onto the awaiting hooks. Two people, on separate ladders  
can now hoist the sub into place. When installed, it can easily be leveled by turning the turnbuckles (Fig. 14).  
If no suitable point exists directly above the desired location, you can use wire rope or chain to make connections  
that are not perpendicular to the suspension point(s). Under no circumstances should the angles exceed +/- 15  
degrees from vertical. Make certain that you follow closely the instructions and regulations for the use of wire rope  
for overhead suspension. Serious injury could result if guidelines and safety margins are not closely obeyed.  
7)  
8)  
In this photo (Fig. 15) we have removed the threaded rod and installed eyebolts with backing nuts into the couplers,  
as described earlier. Detail of the connection with wire rope is shown in (Fig. 8), which is identical top and bottom.  
Take measurements to approximate the lengths of rope you will need. It might be convenient to make some or  
perhaps all of your wire ropes on the ground and use a quick link (Fig. 7) on each end to connect between both  
the suspension point and at the subwoofer. Again, it is important to follow local code and regulations for use of wire  
rope in overhead suspension. Check with your supplier for additional instructions on its use.  
Once two installers have raised the subwoofer to the ropes and the sub is safely suspended, it can be leveled by  
adjusting the rope lengths. Check for even tension on all ropes, and note that it is much easier to let some wire  
slip out of the tighter ropes, rather than trying to pull up and tighten the loose ropes. Once the subwoofer is level,  
installation is complete.
