Product Description

TD15S Highlights:

The TD Series woofers are low distortion, high Xmax, wide bandwidth, bass drivers designed for sealed or vented enclosure applications.   They work well in a variety of applications including subwoofers, bass/midbass drivers in 2way or 3way systems, and automotive SQ subwoofer applications.  The Lambda Motor means they have very low/linear inductance with response extending cleanly to over 1000hz.  The high Xmax allows them to play the lowest notes with accuracy and authority.  TD woofers have been used in high end recording monitors, home theater subwoofers, and extremely high end hi-fi systems retailing for upwards of $100,000. When you want the most accurate woofer for sealed box applications, look no further than the TD Series.

“So why do you have several versions?  What do the different letters, M, S, X, and H mean?”

  • The TD Series woofers come in 4 different varieties allowing for a variety of uses.
  • The TDM woofers are designed specifically for midbass/midrange use.  They have higher efficiency and extremely clean upper end extension, playing cleanly to over 2KHz on axis.  The Xmax is lower, 6mm, which is a trade off necessary to achieve the high efficiency.
  • The TD S, X, and H are all similar and can be used in bass/midbass applications.  The core parts (cone, surround, spider, motor, and frame) are the same among all models.  The only difference between the models is the wire used to wind the voice coils.  All extend cleanly to over 1KHz.
  • The TDS use a 2 layer round wire copper coil for  higher Qts. They are typically the option chosen for sealed box applications and larger vented box applications.  They are often used in larger floor standing speakers.
  • The TDX uses a 4 layer flat wire aluminum coil.  The BL is slightly higher and mass is slightly lower. They are typically used in vented enclosures where more efficiency is desired.
  • The TDH uses a 4 layer flat wire copper coil. They have the highest BL and also highest mass. This allows them to work in smaller vented enclosures and have better low end extension.  They make the best pure subwoofer drivers in the series.
