Orchestra 8-612/C8/32 RP

Der ETON Orchestra 8-612 ist ein 8"-Langhub-Tieftöner für audiophile DIY-Lautsprecher-Projekte, bei denen echter Tiefgang, ein warmes Klangbild und eine berechenbare Gehäuseauslegung im Vordergrund stehen. Mit einer Resonanzfrequenz von 26 Hz (TSP) und einem Qts von 0,30 gehört der Orchestra 8-612 zu den tiefst abgestimmten 8"-Treibern im DIY-HiFi-Segment – und ist damit primär für Bassreflex-Konstruktionen ausgelegt, in denen er sein volles Tiefgangpotenzial entfaltet. Das Äquivalentvolumen von 100 dm³ spiegelt die hohe Membranachgiebigkeit wider und erfordert entsprechend großzügige Gehäusevolumina für eine optimale Abstimmung.

Die verrippte Papier-Membran (RP) kombiniert ein warmes, organisches Klangbild mit konstruktiver Steifigkeit: Die Rippenstruktur kontrolliert Partialschwingungen und stabilisiert das Ausschwingverhalten – ein bewährtes Prinzip im audiophilen Lautsprecherbau. Die 32-mm-Kupfer-Schwingspule auf Kapton-Träger sorgt für einen kraftvollen Antrieb (BL = 9,3 Tm) und einen mechanischen Xmax von ±14,2 mm – außergewöhnlich hoher Linearhub für einen 8"-Treiber, der auch bei hohen Pegeln und tiefen Frequenzen verzerrungsarm und kontrolliert bleibt. Made in Germany, aus der ETON-Manufaktur.

Linear tonal response thanks to paper RP diaphragm – usable from 25 Hz to 1.5 kHz

The frequency response of the Orchestra 8-612 shows the behavior of an 8" woofer designed for maximum low-end extension and a warm, organic sound signature: a smooth, controlled amplitude response from approx. 25 Hz to 1.5 kHz – with 90 dB efficiency and a stable level structure across the entire transmission range. The ribbed paper cone (RP) controls partial oscillations in the upper transmission range and stabilizes the decay behavior – the result is a smooth frequency response without the typical peaks that many 8" drivers with stiffer cone materials exhibit in the upper bass range.

Particularly relevant for DIY developers: The usable transmission range up to approx. 1.5 kHz allows coupling to midrange or tweeter drivers with crossover frequencies from 1.2–1.5 kHz – in 2-way systems directly to a tweeter, in 3-way systems to a dedicated midrange driver. The Qts of 0.30 and the resonance frequency of 26 Hz make the Orchestra 8-612 a pure bass-reflex driver: The lower cutoff frequency in a bass-reflex enclosure can reach below 30 Hz with optimal tuning – true low-end extension without a subwoofer.

The smooth frequency response without dips or peaks in the transmission range demonstrates the quality of the paper RP cone and the drive system. An 8" woofer that sounds the way it measures – warm, controlled, with genuine low-end extension. Made in Germany, from the ETON manufactory.

Qts 0.30 / fs 26 Hz – designed for bass reflex with real low-end extension

The impedance curve of the Orchestra 8-612 shows the behavior of a precisely tuned 8" woofer with an exceptionally low resonance frequency: The impedance peak is at approx. 26 Hz (TSP) – one of the lowest resonance frequencies in the 8" DIY segment.

The high impedance peak confirms the extremely low mechanical losses (Qms = 6.67) and the high compliance of the suspension (Cms = 1.48 mm/N). The Qts value of 0.30 clearly positions the driver for bass-reflex designs: In a sealed enclosure, the low Qts would severely limit the low-frequency extension – in a bass-reflex enclosure, the driver unfolds its full potential with genuine low-end response down to below 30 Hz.

Above resonance, the driver behaves electrically stable: The impedance rises moderately toward high frequencies due to the voice coil inductance (Le = 0.99 mH) – an expected value for an 8" woofer with a 32-mm copper voice coil on a Kapton former, which does not complicate crossover design. The 8-ohm design allows for trouble-free operation with common hi-fi amplifiers. The equivalent volume of 100 dm³ must be taken into account when designing the enclosure: It requires generous bass-reflex volumes for optimal tuning.

The cleanly defined impedance peak without secondary resonances confirms the mechanical precision of the overhung motor system and the quality of the suspension. An 8" woofer that behaves in enclosure calculations exactly as it does in simulation – reproducible, reliable, Made in Germany.
