TW013WA01   13 mm neodymium textile tweeter, 4 ohm

 

 

 

 

TW013WA01 is a very compact high performance tweeter that is ideal either as a super tweeter in high-end Hi Fi speakers or as tweeter in very small compact 2-way systems.

Innovation
Despite being designed for ultimate high frequency performance no compromise has been accepted at the lower frequencies either. The TW013WA01 incorporates an external ring neodymium magnet, which allows effective venting through the center pole to a rear volume. It means that the TW013WA01  offers a very low resonance frequency for its size - even lower than many larger tweeters.

Note 1

Measured in infinite baffle.

Note 2

Tested in free air (no cabinet, no baffle).

Note 3

Measured using a semi-constant current source, nominal level 2 mA.

Note 4

Measured at 25 deg. C

Note 5

It is generally a rough simplification to assume that loudspeaker transducer voice coils exhibit the characteristics of an inductor. Instead it is a far more accurate approach to use the more advanced model often referred to as the “Wright empirical model”, also used in LEAP-4 as the TSL model (www.linearx.com), involving parameters Krm, Erm, Kxm, and Exm. This more accurate transducer model is described in a technical paper (PDF) here.

Note 6

Measured before burn in. The unit is not burned in before shipping.
