{
"feature": "1\" Military A-Specification titanium dome tweeter with butyl rubber surround in cast aluminum housing\nMade to dissipate heat for peak performance. Stamped in a nine-step progressive die for a consistent shape. The phase lens is specifically designed for off-axis performance."
},
{
"feature": "Lightweight mica-filled polypropylene cones\nMica-filled poly blend ensures strength, outstanding frequency reproduction, and durability. This means that mid-bass frequencies remain very musical without the distortions that can be caused by the cone flexing."
},
{
"feature": "Curvilinear design\nThe geometry is specifically engineered to optimize mid-bass response and off-axis performance."
},
{
"feature": "Natural butyl rubber surround\nEnables smooth and durable performance. Flexible piston action UV-protected rubber remains impervious to extreme temperature swings, from very warm to very cold."
},
{
"feature": "1.5\" high-temperature copper voice on Kapton former\nThe former is lighter and stronger than aluminum, which allows the component to support slightly higher frequency extension and efficiency."
},
{
"feature": "Woven fiber cotton poly blend spider\nStabilizes the cone and voice coil in all musical situations."
},
{
"feature": "Balanced Temperature Technology (BTT) cooling system\nThe system uses Balanced Temperature Technology throughout every component. The cast aluminum radial sink speaker frame, crossover plate, and tweeter frame remove excess heat for predictable long-term performance."
},
{
"feature": "External audiophile Q Control crossover network\nGuides the frequencies from the amplifier to each driver (speaker). This system is designed with tight-tolerance components with low-loss polypropylene film caps and air-wound coils for remarkable sound quality."
},
{
"feature": "High-tolerance (1%) metal film resistors\nReduce phase shift for better staging and imaging."
},
{
"feature": "Tweeter hardware\nHardware for multiple tweeter mounting solutions is included."
},
{
"feature": "Die-cast aluminum basket\nDesigned to be lightweight and extremely rigid. The low-profile form can be easily installed in most factory locations with little or no modification."
},
{
"feature": "Solid neodymium magnet in low-carbon steel containment cup\nStrong magnet focuses all the energy around the voice coil."
},
{
"feature": "Gold-plated four-way connection terminal\nFor consistent curvilinear cone performance. Connection types include solder, screw-down, spade, or fork terminal."
},
{
"feature": "Hardware\nFlush-mount ring bracket and holes accommodate OEM and custom installations for the midrange. Available mounting options for the tweeter are flush, flushed angle, and surface mounting. Four holes in the base of the crossover allow for mounting on any flat surface."
},
{
"feature": "Q Series audiophile in-ear studio monitors are included to bring the Q listening experience on the go\nOffer 3.5mm connectors with adapters for both USB Type-C and Lightning devices."
