No problem, we're just now sending out review samples of the RM30 SDE with the DCX2496 digital crossover/parametric EQ included at $3495pr.
As others have discovered, controlling dispersion is very important to achieving good sound in a small environment such as most audiophile's homes. You can't change directivity by crossover alone, and the lobing and cancellation typical of multiway systems in and around the crossover region account for many of the differences we hear between speakers that otherwise measure flat on axis.
I have heard the SP Tech and EP speakers only at shows and liked both, if for different reasons. Right now our digital crossovers mimic our analog filters, i.e. first order slopes and staggered poles. I plan to include dial-up filters suited to user tastes and listening rooms--indeed, we will probably offer to make each speaker pair custom for every user, with his listening room compensated for as much as possible in the processor. This should finally realize the great potential of DSP: highly effective and musical digital correction of loudspeakers, a goal I have striven towards these past 15 years.
I also think the optimum transient response of a sealed design, and not having to deal with the dipole effect which makes open baffle bass so problematic in terms of extension, power handling and distortion levels, will result in a system both highly pleasing sonically and downright easy on the eyes.
