Transducer Lab

At Transducer Lab, the goal is to produce drivers that accurately transform the original signal to an acoustical signal with minimal alteration.

Quality is a factor as well. The drivers are carefully assembled and tested in lab conditions.

Transducer Lab tweeters are matched to better than +/- 0.75db. Each tweeter is thoroughly tested and evaluated to meet our standard specifications.

The ceramic domes on the models N26C, N27B4 are sintered from Al2o3 and B4C material. You will notice the purity of the dome by its finish. The domes operate in pure piston motion to well above the audible range.

The N28BE is a high purity Beryllium dome tweeter with advanced design and premium parts to match. Response to above 55khz with a natural airy sound.

These premium fidelity drivers that are designed and assembled in the USA.

To our building proposals with Transducer Lab drivers.

Mit Glasfaser - statt Alu-Schwingspulenträger entstehen keine Wirbelstromverluste. Daraus resultiert ein etwas besserer Wirkungsgrad. Außerdem versteift der Glasfaserträger die Keramikmembran besser, so dass deren Materialresonanz höher liegt.

The cabinet volume calculations are executed considering an external resistance of 0.3 Ohm. We are using, if no other data is known or available, the information supplied by the manufacturer.

Please note: the frequency response doesn't say much about the cut-off frequency inside the cabinet! Therefore, we mostly give you 2 examples with dimensioning considerations and an indication, how low the loudspeaker will reproduce.
