Product Description

LO15 Highlights:

  • Designed specifically for Open Baffle/Dipole Use
  • Lambda Motor with Full Copper Faraday Sleeve (FCFS)
  • Extremely low and linear inductance
  • Wide bandwidth and extended midrange
  • High Xmax with clean suspension travel
  • Underhung motor for linear Bl
  • Ideal Qts for open baffle speakers

The LO15 was designed specifically for open baffle/dipole use. In open baffle applications, drivers are required to operate at much higher excursions than in typical boxed woofer applications to make up for the roll-off of the baffle. When a woofer is pushed to high excursions, Bl and Le linearity are very critical. To achieve this linearity, the LO woofers were designed with a large underhung motor and Full Copper Faraday Sleeve covering the entire pole. This combination provides the most possible linearity and lowest possible distortion during high excursion use. The high Q and low Fs allow the LO woofers to be very efficient at low frequencies and have a very flat response. While EQ is typially needed to correct for the baffle rolloff itself, no additional EQ is required to flatten the response of the driver.

The LO woofers are similar to the Dipole series but with more efficiency and better upper end extension. The trade-off is lower Xmax, so low end output under 35hz may be more limited. They are a great option for open baffle speakers when emphasis is put more on efficiency and midbass/midrange rather than low end extension.

As with all of our woofers, the LO15 has extremely low and linear inductance. Power requirements for the LO woofers are very low to push these drivers to high excursions. The low power requirements and non-reactive load make the LO woofers ideal for use with tube amplifiers. The LO woofers have some of the best midrange performance of any of our woofers, playing flat well over 2KHz.  Available in dual 8ohm or dual 16ohm coil options to allow  for a variety of wiring options.

Some independent measurements on the LO15 can be seen below confirming the very extended frequency response, low distortion, and linear inductance:
