EARTHQUAKE EWS800+EWS530C In-Wall Speakers 1Pair of Earthquake EWS800 In-Wall 8" speakers and 1 Earthquake EWS530C In-Wall center speaker . Brand new in the box. Open only one speaker for photo.

At A$500, this is a solid-to-good buy for the pair if it’s complete and in clean working order; new pricing puts the EWS800 around A$420 per pair and the EWS530C around A$300 each, so used value on these custom-install Earthquake pieces typically lands meaningfully below retail rather than above it. That makes A$500 look fair if you’re getting both models together, especially if the seller includes grilles, back boxes or mounting hardware, since those are the bits you don’t want to chase later.
What makes them worthwhile is the usual Earthquake pitch: high-output in-wall performance with an LCR-friendly design, so they can do real home-theater duty rather than just background sound. The upside is strongest if the speakers are from one tidy install and show little UV wear, because in-wall gear tends to age more by hard use and rough mounting than by cosmetic handling; if the cutout edges, terminals, or grilles are damaged, use that to negotiate.

Octave Audio traces its roots to 1968, when Karl Heinz Hofmann established a transformer winding factory in Karlsbad, Germany. His son, Andreas Hofmann, joined in 1975, developing early semiconductor and tube amplifiers. In 2000, Andreas took the helm, rebranding it as Octave Audio to channel his decades-long passion for tube-based electronics into high-end hi-fi components.
The brand specializes in meticulously hand-built tube amplifiers, including preamplifiers, power amps, and integrated models like the V 16 Single-Ended and Jubilee series. Octave emphasizes premium features such as external power supplies, balanced connectivity, adjustable gain, and modular upgrades for phono stages and power conditioning. Their in-house transformer expertise ensures low-noise performance across full-range designs, from 8-watt single-ended units to 30-watt powerhouses.
Positioned firmly in the high-end market, Octave commands respect among audiophiles for its German craftsmanship, sonic purity, and innovative tube technology. Hand-assembled with top-tier components at their Karlsbad headquarters, these amplifiers deliver uncompromising musicality, appealing to discerning buyers seeking perfection over mass production.
