Rockville HT120 360w Aluminum Horn Titanium Tweeter with 2" Voice Coil, Top of the line Rockville high frequency driver pre installed in an aluminum horn, Titanium diaphragm tweeter, Bolt-on style system, Type: Compression driver.
RMS Power: 120W, MAX Power: 360W, Sensitivity: 105dB @ 1w / 1m, 34 oz Magnet, 2” High Temperature Die Cast Kapton Voice Coil.
Ferro Fluid Enhanced Voice Coil Cooling, Impedance: 8 Ohms, Frequency Response: 800Hz - 20kHz, We recommend using a crossover that cuts frequencies below 1500 to 3000Hz at -12dB per octave, Our metal horns are heavier and a denser material which ensures they will not generate resonances and unwanted vibrations that can alter the response of the speaker. Also our metal horns will never break even if you go over bumps while driving.
Horn Dimensions: 6.2” x 6.2” x 5.1” (158 x 158 x 130 mm), Throat Diameter: 2", Overall Depth: 7.6” (193 mm), Cutout Diameter: 5.79”, Mounting Depth: 7.36”, Extremely loud and clear highs with an amazing frequency response that can even play some mids, Shallow Mounting Depth.

1Ω or 2Ω ohm selectable impedance RMS: 1500 watts Peak: 3000 watts.

THE SPRING THAT SINGS | Simply use the included stainless steel beater to achieve an array of metallic effects including a finger cymbal ding, a dark metallic coil hit, and a long scrape of the coil. Playing only takes one hand, so it's easy to mute or stretch the coil for even more sound manipulation..
PROUDLY MADE IN THE USA | The TREcoil is made from a 1/4" rod of solid Aluminum/Titanium alloy that is hand-bent and tested by ear in our workshop just north of Nashville, TN..
FORGED FOR SUPERIOR STRENGTH AND SOUND QUALITY | Each coil undergoes high temperature heat treating to harden the metal and to add depth to its sound. The mantle secures the coil in place with a super durable polyurethane coated braided steel cord to keep your triangles hanging year after year..
A SAFE AND CONVENIENT MOUNT | The coil is removable and interchangable with other hanging instruments, making this an invaluable addition to your percussion section. The included stainless steel beater slides easily into a hole drilled in the top of the mantle for storage between uses..
DIMENSIONS | The TREcoil is 5" in diameter and 19" inches in length and comes with one Light Triangle Beater (TREbtr-LTE) that is 8 1/4 x 3/8 x 1/4 inches in dimension..
