What Are Acoustat Speakers?
Acoustat entered the audio scene in the late 1970s, offering full-range electrostatic loudspeakers that made a splash. Their designs, featuring large electrostatic panels, did away with the need for traditional dynamic drivers. This resulted in a clean, detailed sound that was quite innovative for its time. Unlike conventional speakers that use cones to push air and create sound waves, Acoustat speakers use a thin, electrically charged diaphragm suspended between two stationary electrodes. This diaphragm vibrates in response to audio signals, producing sound. Learn more about Acoustat and vintage speaker restoration.
The Electrostatic Advantage
The magic of electrostatics lies in their speed and precision. The lightweight diaphragm responds instantly to changes in the audio signal, resulting in exceptionally clear and detailed sound reproduction. This creates a lifelike presentation, especially with instruments and vocals. Many find that electrostatics excel at reproducing subtle nuances and textures often lost with traditional cone speakers.
Defining Acoustat’s Unique Features
Acoustat speakers are known for their transparent and detailed sound, but they also come with specific requirements. They often demand powerful amplifiers and careful room placement to perform at their best. While the original panels themselves are generally durable, the power supplies and interfaces can require attention due to aging components. One review of the Acoustat 1+1s details this and other considerations. Thankfully, professional refurbishment services are available to keep these classic speakers singing. Compared to another popular electrostatic brand, Quad ESL, Acoustats are often described as having stronger bass and a wider dynamic range, though some argue that Quads offer a slightly purer midrange.
Popular Acoustat Speaker Models and Their Specs
Acoustat produced a range of electrostatic speakers over the years. Here are a few well-known models:
Acoustat 1+1
The Acoustat 1+1s are often described as the “Goldilocks” speakers of the Acoustat lineup. Finding a sweet spot between some of the larger and smaller models (like the 2 and 2+2), the 1+1s offer a balance that many listeners appreciate. Tone Publications notes their unique sound and vintage appeal. They have a sensitivity rating of approximately 83 dB, and if you’re searching for a used pair, prices typically fall between $600 and $800.
Acoustat 2+2
The Acoustat 2+2 speakers are known for their listenability. Stereophile points out their balanced sound, noting they are not overly bass-heavy. This makes them well-suited for a variety of rooms, especially smaller spaces. They’re a versatile choice for those who want electrostatic sound without overwhelming their listening environment.
Acoustat Spectra 33
The Acoustat Spectra 33s are full-range, push-pull electrostatic speakers. A discussion on Stereonet mentions their key specifications: a frequency response of 30Hz–20kHz ±3dB, 4 ohms impedance, 88dB sensitivity, and a power requirement of 100W.

Acoustat speakers excel at retrieving subtle details in the music, allowing you to hear nuances you might miss with other speakers. Think of it like upgrading to a higher-resolution image—suddenly, you see details you never knew were there. One listener described their experience with the Acoustat Model 2s as having “astonishing clarity, detail, and depth” across various genres like jazz, classical, and rock. You can find more user experiences on the Audiogon discussion forum. This attention to detail makes them a popular choice for serious music lovers.
Soundstage and Imaging
Imagine being at a live concert. You can pinpoint the location of each instrument on stage, and the music surrounds you. That’s the kind of experience Acoustat speakers aim to recreate with their soundstage and imaging. They create a remarkably wide and immersive soundstage, making it feel like the music is unfolding live in your room. Stereophile’s review of the Acoustat 2+2s highlights their “listenability,” thanks to this expansive presentation. The precise imaging allows you to pinpoint the location of instruments and vocals within the music, adding to the realism.
Bass Response
Bass response is an area where Acoustat speakers can vary. Some models, like the Model Fours, are known for producing substantial bass, which can be too much in smaller rooms. Think of it like adding too much salt to a recipe—it overpowers everything else. The 2+2s, however, offer a more controlled bass response generally well-suited to a wider range of room sizes. Again, Stereophile’s review of the 2+2s discusses this difference in bass performance between models. Proper room placement is crucial for getting the best bass from any Acoustat model.
Reviews and Opinions
Want to hear what other listeners think? User reviews consistently praise Acoustat speakers. For example, the Acoustat 1+1 floor-standing speakers have earned a stellar 4.8 out of 5-star rating. You can find these reviews on Audio Review. This positive reception speaks to the enduring appeal and quality of these unique speakers.
Acoustat vs. Other Speaker Brands
Acoustat speakers hold a special place in the audio landscape. Their electrostatic technology distinguishes them from conventional speakers, creating a unique sound. But how do they compare to other brands, both electrostatic and traditional? Let’s take a look.
Electrostatic Competitors
In the electrostatic realm, Acoustat’s primary rivals include brands like Quad and MartinLogan. Each brand approaches electrostatic technology differently, leading to distinct variations in sound. A Tone Publications review points out that Acoustat speakers, especially the 1+1 model, offer a different listening experience compared to these competitors. While some may prefer the midrange of Quad ESLs, Acoustat often delivers stronger bass and a wider dynamic range. This makes them an attractive option for those wanting a richer, more impactful sound. The same publication also mentions that Acoustat speakers may initially sound underwhelming, needing a “burn-in” period to fully develop their sonic character.
Traditional Speaker Alternatives
Beyond electrostatic rivals, Acoustat speakers also compete with traditional cone-based speakers. These conventional speakers often perform well where electrostatics sometimes struggle, such as high-volume output and deep bass. However, Acoustat’s electrostatic design gives them an advantage in clarity, detail, and spaciousness.
