## Description

ORA4 140W Powered Reference Speakers with Bluetooth 5.0 and USB-C Input | 4” Woofers with Deep Bass Extension | Bi-Amplified | 80 Hz Automatic Crossover | Reference Quality Sound | Pair | Black

## Features

- STUDIO SOUND – If your speakers aren’t neutral, you’re not hearing what the artist intended. Delivering 140 W of DSP-tuned, bi-amplified Class-D power, ORA4 produces studio-grade sound with deep, authoritative bass from its 4” woofers. Accurate enough to work as a studio monitor and refined enough for HiFi use.
- JACK OF ALL TRADES – Not quite a bookshelf speaker, studio monitor, or computer speaker. ORA4 feels equally at home in virtually any scenario and is perfectly sized for any stand mount or desktop setup. Great sound in a compact package for gamers, creators, musicians, and audiophiles.
- MODERN CONNECTIONS – To cover your digital and analog needs, ORA4 offers three inputs - USB-C for flawless sound from your PC or Mac, Bluetooth 5.0 for pairing with your phone or smart home device, and RCA for your analog gear. An endless amount of audio sources work with ORA4 from the past, present, or future.
- TIGHT SUB INTEGRATION – You don’t have to sacrifice fidelity for low-end grunt. When a subwoofer is connected, a crossover network activates automatically, allowing ORA4 to concentrate on vocals and high frequencies. By offloading bass, ORA4 can play louder with less distortion improving overall sound quality.
- PIXEL PERFECT – Placing a magnet beside your tube TV is a sure-fire way distort picture quality and lower its HP. ORA4’s woofers are magnetically shielded allowing you to place them beside your CRT or PVM without any worries. The RCA input gives you a direct connection to hear your favourite retro soundtracks in all their glory.
- MOUNTABLE – Two 1/4”-20 threaded inserts located at the rear, and bottom, of each speaker let you secure ORA4 to any compatible speaker mount or bracket. Whether you want to free up space by mounting them on a wall, or simply find the perfect spot in your room, you have the flexibility to place them wherever works best.
- THE KANTO ECOSYSTEM – Getting your speakers lined up with your ears and minimizing surface reflections is crucial for extracting the most from your speakers. Unlock the full potential of ORA4 by pairing it with a Kanto speaker stand like the legendary angled S4, cantilevered SE4, raised SP9 and SH6HD, or floor-standing SP26PL or SP32PL.
