TTC Loudspeaker Test Chamber
TTC Loudspeaker Test ChambersPrism Sound and Hill Acoustics are proud to introduce a new line of compact Tetrahedral Test Chambers (TTCs) for consistently stable, convenient and affordable loudspeaker measurements to the new international standard IEC60268-21.
No Anechoic Chamber required for Free Field resultsUsing a TTC it is not necessary to work in an anechoic chamber and furthermore the TTC allows measurements below the lower limit of most practical anechoic chambers. The TTC brings precise and repeatable free-field loudspeaker measurement over the full audible frequency range within reach of every audio development engineer.
Repeatable Measurements to IEC60268-21 sec 13.1(d)The Tetrahedral Test Chamber ensures a precisely defined, stable and modally minimised environment, completely free from the set-up variations that clouded results from former less precise measurement setups.
Precise free-field responseThe Tetrahedral Test Chamber's low frequency response is calibrated and a frequency response correction curve is supplied with each chamber which can then be appled to results measured by the internal microphone.
High frequency internal reflections are sufficiently absorbed by internal dampling materials so that the measured HF response can be combined with the compensated LF response to provide an equivalent, accurate free field response.
The most compact and economical solution for free field measurementTetrahedral test chambers provide free field response with best repeatability over the widest bandwidth while also offering a compact and economical solution.
TTCs are available in the following sizes:
|Model (Also base side length in mm)||Suitable for speaker sizes|
|170||up to 30mm|
|350||up to 100mm|
|750||up to 200mm|
|900||up to 300mm|
|1500||up to 460mm|
