The S15 speakers are the Signature version of the Performance P15.  The difference between these 2 versions are their tweeters, xovers, internal wiring cables and the binding post which gives the Signature more clarity and bigger sound stage. Please read the Performance P15 description for more information. 

The tonal balance for these 2 versions are similar as they come from the same designer.


Greg Borrowman, the editor of Australian Hi Fi magazine recently reviewed the P15 Signature Edition - he concluded "... are superb transducers. For their size there are few - if any - other loudspeakers that can even approach their level of performance, and if we're talking midrange and treble, there are few that come close irrespective of their size and price." read the full review here.


The Signature S15 features a striking timber cabinet. These beautifully engineered cabinets are a bass reflex front ported configuration featuring 18mm thick solid MDF timber walls.

Two stunning finishes are available, real timber (Bubinga) veneer or a piano graphite. The cabinets are extensively braced and dampened to prevent unwanted audio interactions and resonances.

The curved surfaces don’t just look stylish, they are also highly functional and help to increase rigidity and prevent undesirable internal standing waves. These attributes as well as the carefully designed proportions of the cabinet are one of the keys to the Signature S15’s incredible sound.


The Signature S15 uses the same ring radiator tweeter found in Whatmough’s flagship speaker, the Paragon. This ultra high end tweeter is incredibly fast and detailed while also sounding extremely smooth and open. The tweeter’s frequency range extends beyond 40kHz and helps create a speaker with massive bandwidth and a very flat response.

The bass driver features a 33mm, high temperature, voice coil and large double magnet system to match perfectly with the dynamic characteristics of the tweeter.

Crossover Network

These beautifully crafted speakers utilise premium quality polypropylene film capacitors housed in a non-magnetic case with pure copper soldered lead-out wires. The hand built crossover networks used in the Signature S15 are point-to- point hard wired and all components are meticulously positioned to minimise any interaction.

Cardas (USA) cabling is used as internal wiring throughout. Despite the difficulty involved in using these premium, individually insulted, cables within such an intricate application the resulting stunning sonic performance is worth while.

Binding Posts

Our entire range of Signature Series speakers, including the Signature S15, use solid copper Cardas (USA) binding posts. These long billet copper Cardas binding posts are silver plated and Rhodium coated to ensure the best connection and a lifetime of incredible performance.

These terminals are considered by many to be the world’s best. For best performance, Whatmough recommends the Signature S15 be connected in bi-wire or bi-amped configuration.
