The “bullet" phase plug is made from pure aluminum acting as a radiator cooling system for the voice coil and machined to perfection for even sound dissipation. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound.
Also featuring a cloth M-roll surround helping resonance to be kept under control making for an easy transition to a super tweeter.
The suspension design of this mid range features the single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.
You can expect outstanding sound stage quality and realistic sound reproduction for a great value.
Built for compact spaces and able to handle 400 watts of continuous power. Its slim design makes this the perfect car audio door speaker, allowing it to be utilized in endless ways.
Loud and clear vocals all within 2.68″ of mounting depth without sacrifice quality and performance.
