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 T4.8 end on end to
create a taller line array the height of the line array must
correspond to the ear height range of the listeners in both
seated or standing positions.
The T4.8 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.
The T4.8 is shipped with a quick install U bracket.
The T4.8 line array full range column speaker is one
o three speakers in the T Series. This attractively designed, f

Technical Specifications
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
curve to test the speaker in the anechoic chamber, increasing the
signal to make the speaker work at its rated impedance and set the
power output at 1W, then test the sensitivity 1m away from the
speaker.
3. MAX.SPL
Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber , increase the
signal to make the speaker work at its maximum power output
level, then test the SPL1m away from the speaker.
4. Rated Power
Use Pink noise to the IEC#268-5 standard to test the speaker,
increase the signal for a continuous period of 100 hours, the
rated power is the power whenthe speaker will show no visible
or measurable damage.
