The El Diablo is a flagship floorstanding loudspeaker from Peak Consult, a Danish manufacturer, built as a three-way, dual-ported design representing 25 years of speaker development experience distilled into the brand's most successful model to date. Since 2007 the El Diablo has been constantly refined with updated drivers, improved crossover components and revised cabinet construction, with the latest version representing a complete redesign significantly improving on earlier iterations.
Key specs that matter
Rated response is 20Hz to 45kHz at -3dB. Sensitivity is a claimed 94dB, though independent measurement found a somewhat lower but still usefully above-average figure closer to 90dB. Nominal impedance is specified at 7 ohms, though measurement showed the actual impedance behaves more like 4-5 ohms across much of the audio band, remaining free of the resonance-indicating wrinkles that would suggest cabinet problems. Crossover frequencies are 200Hz and 4800Hz. The three-way design uses a 1-inch non-ferrofluid-cooled soft-dome tweeter made by fellow Danish company Scan-Speak, using a neodymium motor with a nonresonant aluminium backwave chamber, alongside a 5-inch plastic-cone midrange and two 9-inch plastic-cone woofers with large magnets, both custom-built to Peak Consult's specifications by AudioTechnology, co-founded by Ejvind Skaaning, who also founded Vifa/Scan-Speak and Dynaudio. At 44.5 x 11.8 x 21.5 inches and 188 lbs (85.5kg) per speaker, the hand-built enclosure glues together varying thicknesses of high-density fibreboard with specially placed resonance suppressors, encased in a 1-inch skin of solid, hand-selected Italian walnut - no two interior walls run parallel, specifically to avoid standing waves. Internal wiring uses Stereovox cable, terminating in two pairs of WBT Platinum Signature bi-wire binding posts.
Sound and use context
Expect a tactile, deeply layered presentation with excellent front-to-back depth - the front of the soundstage develops well ahead of the speaker itself, playing subtle orchestral strings with the same authenticity as a full symphony orchestra or hard rock band.
Pairing
The designer specifically describes this speaker as easy to drive despite its considerable scale, thanks to a gentle, low-current-drawing phase angle across the claimed response, though buyers should confirm actual impedance behaviour with a dealer given the difference between specified and measured figures.
Alternatives
Peak Consult's Sinfonia sits below this flagship as a more accessible three-way alternative, and the compact Sonora brings the brand's core qualities into a smaller stand-mount format, worth comparing directly with a dealer given the considerable investment the El Diablo represents.
