Gorilla is an analog,
mid-field monitor designed for
critical mixing and mastering applications.

Acoustic Suspension is our Ethos. 

Acoustic suspension (sealed) is a type of loudspeaker enclosure in which drivers are mounted in a cabinet with no ports or vents. While vented (ported) systems help with the bass frequency output, the trade-off is that they introduce phase delay and inaccuracy. Carefully designed Telegrapher sealed systems can deliver cleaner and tighter bass than any ported system in the market. And yes, although, ported systems can deliver higher volume in a smaller enclosure, acoustic suspension systems are most suitable for critical listening environments where monitoring levels are moderately low by the nature of the job.

Or to put it in simpler terms: We may not be the loudest but our precision and clarity is second to none.

  • Frequency range: 20 Hz - 20 kHz
  • f3: 49.8 Hz / f6: 41 Hz 
  • Linearity +/- 1.5 db between 50.2 Hz - 19.2 kHz

Analog Crossover

This is the heart of Gorilla which is an active, analog crossover based on Linkwitz–Riley* filters. 

* A Linkwitz–Riley (L-R) filter is an infinite impulse response filter named after its inventors Siegfried Linkwitz and Russ Riley. This filter type was originally described in Active Crossover Networks for Noncoincident Drivers in the Journal of the Audio Engineering Society.

Protection Circuits

If a critical electrical failure or high frequency signal (like microphone feedback) is detected, the amplifiers are shut down immediately and the red protection led on the front will be enabled.

In addition, if the internal temperature passes the threshold of safety, the amplifiers will be switched off until they cool down. 

Gorilla will also warn you in the case of clipping of audio signals. During normal operation you should see the white led on. As you turn the volume up you might observe occasional clipping indicated the red led flashing. If the clipping becomes continuous, the amplifiers will be shut down to protect your gear and your hearing.

Each driver has its own amplifier. So, in a pair of Gorillas there are 6 independent amplifiers.


We have been meticulously searching for and testing the best woods to build Telegrapher loudspeaker enclosures in the way it facilitates clarity and tone. Every enclosure we create is crafted by artisans using FCS (Forest Stewardship Council) accredited birch trees sourced from the forests of the eastern Black Sea Region. The Black Sea Region runs along Turkey’s Black Sea coast, bordering Georgia to the northeast which is a natural habitat of birch trees. Our selection and acceptance procedures of the logs are aligned with industrial manufacturing principles to ensure quality and longevity. Our goal is to make timeless loudspeakers that will serve you and your future generations for countless years. 

As a main principle we will never outsource our enclosure manufacturing.

You can use GORILLA as your main monitors, as well as mid-field monitors in a larger setup with bigger main monitors.

Safety Precautions

We recommend maximum 87 dBC (average) at your listening spot while working with Gorillas. On higher listening levels, you can reach maximum cone excursion quickly and damage your low frequency drivers. 

Note: Smartphone applications are generally measuring dBA, which may give you a very different result than dBC. 

Here is our detailed suggestion for mastering: Mezzo piano around 75-78 dBC, Mezzo forte around 79-80 dBC, Forte around 82-83 dBC and Double forte around 85 dBC. (Detailed suggestion is from dear Bob Katz, taken from a conversation.)
