Know before you buy
The 16-ohm impedance is specifically chosen to provide an ideal load for tube amplifiers. It allows these amplifiers to operate more efficiently and with less distortion, resulting in a cleaner, more stable sound.
Yes, their high sensitivity of 101dB makes them an excellent match for low-powered tube amps. You will get plenty of volume and dynamic punch even with amplifiers that produce only a few watts of power.
By minimizing the crossover, the signal path remains cleaner and more direct. This design choice significantly improves midrange clarity and preserves the natural, coherent sound of the 10.3-inch full-range driver.
The QuietCoat coating is applied to the MDF cabinet to reduce internal resonance and vibrations. This ensures that the cabinet remains inert, preventing unwanted coloration and allowing the drivers to produce a tighter, more accurate sound.
The 10.3-inch full-range driver is designed to handle a wide frequency range with impressive dynamic punch, so most listeners find a subwoofer unnecessary. However, if you prefer extreme sub-bass extension for home theater, you may choose to add one.
The Soul Superfly has a 12-inch square footprint and stands 38 inches tall, making them relatively compact for floorstanding speakers. They are designed to be freestanding, so you should allow a little room away from the walls to optimize their soundstage.
