EI Diablo



The El Diablo has been constantly improved over the years with updated drivers, better crossover components, new cabinet construction etc. The latest version in 2021 is a complete redesign of previous versions. The cabinet, drivers and cross-over are significantly improved, and the speaker is now even more highly competitive among top High-End speakers worldwide. The Diablo is a real statement speaker in every listening room, regarding esthetics and foremost sublime musical performance.

Design and development process has had main priority to create the most balanced and natural reproduction at all listening levels. It plays the subtle orchestral strings in the same authentic way as it reproduces a full symphony orchestra or a hard rock band. The heavy and extremely well damped cabinet is equipped with a ported double bass configuration. The special designed drivers in El Diablo are uncompromisingly reproducing all music from the highest tones to the lowest frequencies with uncompressed dynamic. The rigorous Peak cabinet construction yet again demonstrates its importance for realistic music reproduction.

The midrange is the most important driver rendering realistic and natural sound and the El Diablo midrange is especially developed to fulfill one of Peaks primary virtues, making the speaker disappear when listening to music. Through countless hours of listening, tweaking, and improving the 2021 midrange and separate cross-over, it now performs idealistically well together with the bass drivers and the tweeter, enhancing our goal to open the sound picture to the next level. The Peak engineers have spent months with measurements and listening sessions to achieve a linear frequency response, optimizing the phase and transient response and level the impedance to perfection. The linear impedance is another true virtue of all Peak speakers. Linearity in the impedance cause an easy load for the amplifier and will have a positive effect in sound quality as the amplifier can show it´s true and effortless potential. Peak has always put a lot of attention to this matter and constantly seek to endeavor for the perfect flat impedance curve.

The El Diablo signifies 25 years of experience in speaker development of the highest quality. Our vision has always been: No compromises and cost not object to warrant this to our customers:

Experience Reality


The Drive Units

Our handmade drive units are the ”beating hearts” of each Peak speaker built. Clearly, we use only the most sophisticated driver technology as regards to magnet technology, basket, voice coil or cone and dome materiel etc. As it is important with unique drivers to various purposes it´s essential that configuration of the driver accentuates the demands for the specific purpose. At Peak speakers we focus intensively on each part and component keeping the vision for the completed product and the overall performance in mind.

The Tweeters

All Peak speaker systems are designed with a 26 mm silk soft dome tweeter as this principle grants the best transient response and the most natural sound. These tweeters are handmade in Denmark with highest accuracy available due to cutting edge technology and highly skilled craftsmen. ​

  • A roll surround and textile dome diaphragm provide a flat frequency response to above 30KHz with outstanding off-axis dispersion.
  • The unique magnet system consists of 6 neodymium magnets in a precise configuration that is far superior to the performance of traditional motors.
  • A unique rear chamber eliminates unwanted reflections and resonances.
  • The tweeters are matched within the smallest tolerances.

Midrange and the bass drivers

All Midrange and bass drivers in PEAK speakers are tailor made to fit the driver configuration required for each specific model. The drivers are extremely fast and move without any dynamic compression due to the mechanical construction and rear ventilation. These drive units are all hand build in Denmark.

Unique technologies:

  • One-piece sandwich molded cone that has no breakups and the ultimate balance in rigidity and damping.
  • Flow optimized diecast basket with internal magnet system minimalizing basket reflections.
  • Kapton voice coil with aluminum wire and hexacoil winding technology resulting in capability of high-power handling and minimum weight.


The Peak Cabinets

The cabinets for all Peak speakers are produced in house in our own artisan’s workshop. This supreme craftmanship is the DNA of Peak speakers originating from the outstanding Danish furniture tradition.

There are two main criteria for our cabinets:
The first is a construction that eliminates all resonances. In contrast to a musical instrument, where the resonance of the corpus defines the beautiful sound, a speaker cabinet must not have a sound itself. Resonances in speaker cabinets will affect the music reproduction. We put a lot of effort into eliminating resonances to least possible level where the music will not be affected.

Our cabinets are created from numerous layers of HDF affixed with special damping glue to a solid wall thickness above 30mm. Inside the cabinets we use several accurately calculated bracings making the cabinets extremely rigid. Furthermore, all cabinets are covered with a 14mm hard wood and acrylic finish. The extreme weight of Peak Speakers emphasizes these excessive measures.

The next step to a perfect cabinet is the rigorous finish and final esthetics. We use real hard wood in particular American Walnut as the finishing coat to our cabinets. Here it becomes obvious how thoroughly our artisans perform their skill! The Peak owner can see, feel and even smell this superior quality. The acrylic bar on the side of the speaker completes the timeless and elegant design.

All together a fully completed Peak cabinet is the perfect environment for our high-performance drive units. They are able to perform with no limitation in dynamics and musical balance presenting you to experience reality.


The Crossover

The crossover being a vital part of a speaker it may be difficult for the end user to understand what it does, and consists of, as it cannot be seen due to the internal location within the speaker. What is the exact purpose and why are Peak´s crossovers in a superior category of their own?

The crossover separates music signal into specific frequencies for each driver, adjusts the level of the drivers together and balancing the frequency response. All Peak speakers have an integrated equalization of the impedance making the impedance curve exceptionally flat. This causes a significant advantage for the amplifier as it easily can perform as intended not troubling with unwanted heavy loads.

Peak speakers are equipped with extreme high-quality components: capacitors, coils, and resistors. Most of these parts are handmade. Each driver section has it´s designated crossover meaning that Peak speakers contain of as many crossovers as they do drivers. To avoid microphonic effects the separate parts are mounted using a special damping glue together with the finished crossover being totally separated from the driver cabinet! This crossover philosophy means that no acoustic energy can influence or obstruct the intentions of the crossover. The selection of all crossover components and further development is done through countless listening session by our engineers in close cooperation with dedicated audiophiles. The sensitivity of human hearing is outstanding and as our ears can tell differences that can´t be measured it vital to the Peak team only to complete our extreme speakers with these extraordinary “tools” we all are equipped with.
