1-inch military A spec titanium dome tweeter with butyl rubber surround in a cast-aluminum housing, specially made to dissipate heat for peak performance. Stamped in a 9-step progressive die, which gives the overall form a consistent shape. The phase lens is specifically designed for off-axis performance.


Lightweight mica-filled poly blend for strength, superior frequency reproduction, and durability. This means that midbass frequencies remain very musical without the distortions that can be caused by the cone flexing and with the curvilinear design the geometry is specifically engineered for the best midbass response and off-axis performance.


Natural butyl rubber surround for smooth and durable performance. Flexible piston action UV-protected rubber which will be impervious to temperature swings of very warm and cold.


1.5-inch high-temperature copper voice on Kapton former. The former is lighter and strong than aluminum – which allows the component to support slightly higher frequency extension and efficiency.


Woven fiber cotton-poly blend spider stabilizes the cone and voice coil in all musical situations.


Balanced Temperature Technology (BTT) is used throughout every component in this Q Speakers system. The cast aluminum radial sink speaker frame, crossover plate, and tweeter frame remove excess heat for predictable long-term performance.


Hardware for multiple tweeter mounting solutions is included.


A diecast aluminum basket is designed to be lightweight and extremely rigid. The low-profile form can be easily installed in most factory locations with little or no modification.


A solid neodymium magnet in a low-carbon steel containment cup is the strongest magnet that can be used and focuses all the energy around the voice coil.


A gold-plated, 4-way connection terminal is oppositely mounted for consistent curvilinear cone performance. Connection types include solder, screw-down, spade, or fork terminal.


Q Series audiophile in-ear studio monitors are included to bring the Q listening experience on the go. 3.5mm connection with adapters for both USB-C and Lightning connection.
