“The cabinetry is top notch on these speakers. The woofers and horn blend seamlessly with the smooth walnut veneer. At close to 62 lbs, I could move them around myself, but the HDI-3600 is clearly well built. Internal bracing makes for a solid feel, and most importantly, neutral sound performance. On the back are the two rear-firing ports and dual terminals for optional bi-wiring/amping. Magnetic grill covers attach to the front and extend the full height of the speaker. However, I prefer the look of these speakers without the grills on. Three 6.5” drivers and a 1” compression driver make up the HDI-3600. The 6.5” drivers are cast frame, Advanced Aluminum Matrix cone woofers with 1.5-inch voice coils. The 2 ½ way design means that all three 6.5” drivers get low-end spectrum duties with one also taking on the mid-range as well.”

“Every bit of the shape is deliberately designed in order to provide a seamless transition from the low and mid-range drivers to the high frequency compression driver and uniform dispersion for smooth in-room response. Frequency response is designed to be neutral on-axis and off-axis, helping to keep the same tonality in different seating positions, but also from in-room reflections.”
