Sensitivity
Bookshelf Speakers
Nominal Impedance of the 4 Ohms means that the JBL Summit Ama is a difficult to drive speaker from nominal Impedance perspective, make sure that you choose an amplifier than can provide 4 Ohms for this speaker.
Many AVRs (audio/video receiver) in the market may have difficulty when the speakers dip below the 4 Ohms levels (this may cause clipping or even physical damage), so we recommend to not pair the JBL Summit Ama with an AVR but use an Integrated Amplifier instead.

Input Type
Summit Ama has Binding post type connectors and lets bi-amping/bi-wiring. Bi-wiring can enhance the overall transparency of your loudspeakers by using separate speaker wires for the low and high-frequency drivers from a single amplifier. Bi-amping, on the other hand, involves using separate amplifiers for the high and low-frequency drivers, potentially resulting in a greater dynamic range and reduced distortion.
