The LDW + Model 1 DSP was the result of five years of continuous development to provide the best fit, electrically, acoustically and ergonomically for your smaller planar or open baffle dipole speakers.  It is the fastest, best performing woofer you have ever heard because it has a supercardioid polar response and NO cabinet energy storage. 

In 2025 we improved the Model 1 LDW into the LDW+ by strengthening the cabinet and replacing our DSP Amp with the SPEAKERPOWER     SP1-300 HT 300W ICEPower Class D amp with an Integral pre-programmed DSP
