TD15M

TD15M Highlights:

• Lambda Motor with Full Copper Faraday Sleeve (FCFS) (Apollo Option available)
• Extremely low and linear inductance
• Ultra wide bandwidth for detailed midbass and midrange
• Designed for live sound, high efficiency theater, and critical monitoring
• Ideal UPGRADE for many vintage drivers (2226H, 416, 421, 5158G, etc)

The TD Series have set a new standard for performance and durability. They are designed for high efficiency applications where accuracy and low distortion are the top priority.   They are an ideal solution for critical monitoring applications and high efficiency theater.  Due to the high power handling, the TD woofers are also at home providing sound reinforcement for live sound applications.   The Lambda Motor means they have very low/linear inductance and the incredible accuracy the TD woofers are known for.  They are rated for 500W continuous input power.  Power compression is also incredibly low due to the combination of shorting rings and the phase plug.  The Apollo Upgrade is available which further lowers distortion and increases the heat transfer away from the voice coil.

The TD15M is a high efficiency, low distortion, wide bandwidth driver of which there is no comparison. The TD15M extends cleanly to over 2Khz for use in 2way systems.    Ideal for upgrade for replacing many vintage drivers.
