Product Description

The T4.4 line array full range column speaker is one

o three speakers in the T Series. This attractively designed, f

120 W RMS , in no vat ive s pea ke r d eli vers hig h spe ech
intelligibility and natural sounding music in a wide range
of applications through its 4" full range drivers. A ver tical

line array of 4 drivers provides control over a hori zontal

and vertical pattern of 180 x 30 and reproduces the critical

vocal range 90Hz-1 6kHz without requi ring a proc essor.

A dif fu se r plate (patent p en di ng ) is fitted t o the centre

d river s t o a ss ist wi th t he vertical pa tte rn c on tro l.

The T4.4 sp eaker can either be used in singles, mul tiples

or stacked using the optional accessories in many indoor

applications such as Houses of Worship, Shopping Malls,
Transport Terminals, Theme Parks, Meeting Rooms, Schools,
Small Auditoriums. When stacking the T4.4 end on end to
create a taller line a rray the height of the line array must

correspond to the ear height range of the listeners in both
seated or standing positions.

The T4.4 is manufactured from 15 mm plywood meeting a

tensile strength of 3500N and is finished in either black or
white using a very durable textured paint. The metal speaker

grill is powder coated and passes all rust resistance tests.

o o

Adding the optional line transformer accessory makes the
T4.4 line array speaker very versatile in 70/100v systems.
To enhance the already great performance of the T4.4 you

can use the EQ filters provided.

Applications

churches/temples

multifunction halls

Speaker Testing Method

1. Frequency Response

Use Pink noise to test the speaker in the anechoic chamber, adjust the
level to make the speaker work at its rated impedance and set the output
power at 1W, then test the frequency response 1m away from the

speaker.

2. Sensitivity

Use full range Pink noise which has been modified using an EQ
cur ve to test the speaker in the anechoic chamber, increasing the
signal to make the speaker work at its rated impedance and set the

power outp ut at 1W, t hen test the sensiti vity 1m away from the

speaker.

3. MAX.SPL

Use full range Pink noise which has been modified using a n EQ
curve to test the speaker in the anechoic chamber , increase the
si gna l to mak e the sp eaker work at it s maxim um power output
level, then test the SPL1m away from t he speaker.

4. Rated Power

Us e Pi nk noise to the IEC# 26 8- 5 st andard to test the speaker,

i ncrease the signal for a continuous peri od of 1 00 hours, the

rated power is the power whe n th e spe aker will show no v isib le

or measurable damage.
