Brand: Acoustic Research

The Acoustic Research AR-11 is a floor-standing loudspeaker that was originally introduced in the late 1970s. It is a part of the AR-1 series, which was known for its sleek design and high-fidelity sound. Some notable features of the AR-11 include:1. Two-way system: The AR-11 uses a two-way system, meaning it only has two drivers - a woofer and a tweeter. The woofer handles bass and midrange frequencies, while the tweeter handles high frequencies. This design keeps thelorium of the speaker simple and minimizes phase shift issues.2. Crossover network: The AR-11 features a first-order acoustic crossover network, which is designed to blend the sounds of the woofer and tweeter seamlessly. It works by filtering each driver's frequency range, preventing the two frequencies from clashing and creating a symmetrical soundstage.3. Acoustic suspension design: The AR-11 uses an acoustic suspension, or sealed-box design. This design increases the efficiency of low frequencies by minimizing the sound loss from the speaker's rear port.4. Rugged cabinet: The cabinet of the AR-11 is made of thick MDF (medium-density fiberboard). This material serves to provide solid acoustics and eliminate unwanted resonances caused by vibrations.5. Grill design: The AR-11 grill is composed of high-impact acrylic material, which is durable and lightweight. It has perforated metal behind it, which reduces reflections and prevents echoing sounds.The Acoustic Research AR-11 remains a highly sought-after vintage loudspeaker today, renowned for its crisp sound and sculpted design. It has been used in high-end audio systems, and can still be found in great condition on the second-hand market.
