Classic 25 Last Edition

Pure sound

Continuously improving what is already good is one of Audio Physic’s key secrets to success. This is once again evident in the new CLASSIC 25 Last Edition, which incorporates numerous solutions, materials, and technologies from our Reference line. The result is an exceptionally mature loudspeaker for its price class—one that already comes remarkably close to the acoustic performance of our larger models.

The MDF cabinet of the CLASSIC 25 Last Edition is elaborately engineered and extremely rigid thanks to numerous internal braces. In the Walnut wood version, natural real-wood surfaces meet elegant black glass on the slim front baffle, creating a look of understated sophistication.

As with its predecessor, the CLASSIC 20, the CLASSIC 25 Last Edition uses the familiar sandwich cabinet design known from models such as the Avanti or Midex for its high-gloss glass surfaces: the inner MDF корпус is clad on the outside with panels of back-painted glass. A special bonding method using 2 mm thick acrylic strips ensures a permanently elastic connection between the two materials. With their completely different resonance characteristics, they are no longer able to develop any cabinet coloration of their own.

The defined spacing also creates a double-glazing effect: sound radiated backwards into the enclosure can hardly escape to the outside. This allows the tweeter and midrange drivers to work without interference. You don’t hear a loudspeaker — you hear pure music!

Another advantage of the glass panels is their elegant and extremely durable high-gloss finish. Even after years of use and care, it still looks as pristine as on day one, without losing any of its shine or its exceptional sense of depth. A surface quality this impressive and long-lasting simply cannot be achieved with conventional lacquer finishes.

Special attention was paid to the bass range, as this is where the highest loads occur. The newly developed, highly powerful woofer — a 21.5 cm long-throw driver — is not mounted visibly on the front or side as with many speakers, but works hidden inside the cabinet. The sound is emitted through two precisely tuned openings.

This special design offers several advantages: on the one hand, the CLASSIC 25 Last Edition reaches impressively deep while remaining precise and clearly defined at all times. On the other hand, it is far less sensitive to placement in the room than conventional designs. Even when positioned close to a wall, it impresses with fine detail and transparency across the entire frequency spectrum.

The remaining driver complement of the CLASSIC 25 Last Edition is also state of the art: it features Hyper Holographic tweeter and midrange units (HHCT III and HHCM SL). Their special dual-basket design ensures that the moving components of the drivers — such as the diaphragm and voice coil — are not directly coupled to the baffle, but instead mechanically decoupled.

This engineering effort is considerable, but it pays off: the result is a sound signature defined by exceptional precision, outstanding detail retrieval, and a highly neutral tuning.

All in all, compared with its already excellent predecessor, the CLASSIC 25 Last Edition represents a significant step forward both in construction and in sound. It even comes surprisingly close to the structurally similar AVANTI from the Reference line. In its own price class, the CLASSIC 25 Last Edition therefore has nothing to fear from comparison!

Sandwich Cabinet Construction

Our unique Sandwich Cabinets are an innovative way to stop the speaker cabinet from developing an acoustical life of its own. It is especially effective with our stylish glass-finished speakers as the relatively high weight of the glass panels helps dampening the cabinet even better.

HHCT III – Hyper Holographic Cone Tweeter

Many AUDIO PHYSIC Core Technologies have been combined to build the HHCT-III tweeter. Together, they serve a single purpose: To guarantee an authentic rendition of the music, unaffected by any unwanted vibrations.

HHCM SL

The HHCM SL works without a spider, which means that kinetic energy is transferred in an unimagined way. This creates an outstanding and natural music reproduction that you can’t believe until you hear it.

HHCM SL – Revolutionary performance in the midrange

Dual Basket Design

AUDIO PHYSIC’S unique DUAL BASKET DESIGN is a true break-through innovation and the most important part of the HHCM-III technology. Instead of the tradition single basket, our HHCM-III features two separate baskets to prevent and subdue unwanted vibrations already at the source.

CCAC – Ceramic Coated Aluminium Cone

By coating a conical aluminium diaphragm with a special ceramic material, AUDIO PHYSIC creates a diaphragm that is at the same time very light as well as extremely rigid. When used together with ACTIVE CONE DAMPING technology the cone diaphragm is virtually immune against any partial oscillations that would otherwise impair the sound.

Invisible Subwoofer

Some of our speakers feature an internal woofer inside the cabinet provides the same deep bass and punch as an additional subwoofer without anyone ever having to see it.

3-Way Design

The 3-way speaker features three different drivers that share reproduction of the entire frequency range. One or more woofers, a midrange driver and a tweeter. Usually the crossover frequency between low and mid frequencies is set between 150Hz and 300Hz, and between 2,000Hz and 3,000Hz for the transition from the midrange to the tweeter.

Ceramic Foam Bracing

Ceramic Foam is a high-tech material used for internal bracing in many of our speakers. It is much stiffer than MDF although it consists of 85% air. This means, the room taken up by the internal bracing is also part of the effective volume of air the drivers need to work. By using Ceramic Foam, we can build loudspeakers that match and out-perform much bulkier speakers.

VCF – Vibration Control Feet optional

The best feet for our – and other – speakers. VCF provide a substantial improvement of sound performance by reducing transfer of unwanted vibrations while at the same time protecting delicate surfaces. Also available as VCF Component for Hi-Fi separates and as VCF Cable Supports.
