Lautsprecher
Graham Audio ist ein britisches Familienunternehmen mit Sitz in Newton Abbot, einer kleinen Marktstadt in Devon, Südwestengland. Wir sind begeistert von hochwertigem Audio und glauben, dass die klassischen BBC-Lautsprecherdesigns ein Maß an Neutralität, Transparenz und Realismus bieten, das heute anderswo schwer zu finden ist. Mit modernen Komponenten und Produktionstechniken konnten wir die Leistung maximieren und gleichzeitig den ursprünglichen Designs treu bleiben.
Wir mögen klein sein, aber wir sind stolz darauf, mit einigen der besten Talente der Branche zusammenzuarbeiten, darunter Derek Hughes und Volt Loudspeakers. Unsere Lautsprechersysteme sind auf der ganzen Welt von sorgfältig ausgewählten Verkaufsstellen erhältlich, die über vollständige Demonstrationseinrichtungen verfügen, und unterstützen Sie bei der Auswahl und Einrichtung.
Alle Lautsprecher werden vor Ort von Hand zusammengebaut. Eine Person ist für jeden Schritt der Produktion verantwortlich, einschließlich des Testens und Vorsprechens. Eine zweite Person überprüft das fertige Produkt, wiederholt die Tests seherlich und speichert die Ergebnisse für die zukünftige Referenz. Als Teil des Testverfahrens werden alle abgeschlossenen Lautsprecher mit unseren Master-Referenzproben verglichen, um die vollständige Konsistenz zu gewährleisten.
Das Unternehmen wurde von Paul Graham gegründet, der mehr als 20 Jahre in allen Bereichen des professionellen Audio, einschließlich der Aufnahme- und Rundfunkindustrie, sowie in Live-Sound und Performance gearbeitet hat. Von all den verschiedenen Ansätzen hat Paul immer den "BBC-Sound" sowohl für professionelle als auch für persönliche Anwendungen bevorzugt, befürchtete aber, dass viele der klassischen Designs für immer verloren gehen würden, da eins nach dem anderen die überlebenden Beispiele nach vielen Jahrzehnten des Betriebs allmählich scheiterten. Ein paar zufällige Treffen und einige lange Gespräche später wurde beschlossen, dass der einzige Weg, dieses Vermächtnis zu bewahren, darin bestand, die Zustimmung der BBC einzuholen, um sie selbst aufzubauen.
Ophidian wurde 2011 mit dem Ziel gegründet, hochwertige britische Lautsprecher zu produzieren, die ihre physischen Dimensionen übertreffen.
Alle Ophidian-Lautsprecher verfügen über die einzigartige AEROFLEX-Basstopologie, die eine saubere und genaue Basswiedergabe sowohl von kleinen als auch von großen Lautsprechersystemen gewährleistet.
Jeder Ophidian-Lautsprecher wird in Großbritannien nach anspruchsvollen Qualitätsstandards handgefertigt.
Hunderte von Stunden Design-, Prototyping-, Mess- und Hörtests wurden in die Erstellung jedes Ophidian-Lautsprechers investiert. Ich hoffe, Sie genießen das Endergebnis!

The BBC LS6
Following the success of the Graham Audio LS3/5 and LS5/9, we were curious to discover what could be done with a cabinet that was sized somewhere between the two.
The result is the Chartwell LS6, designed by Derek Hughes. A custom built 6 inch long-throw bass drive unit mated to a compact 17 litre cabinet gives bass extension and power handling that is comparable to the LS5/9. The bespoke 19mm dome tweeter extends to beyond 20kHz. The overall response retains the smoothness of both the LS3/5 and LS5/9.

The BBC LS6F
Building on the success of our popular LS6 monitor, the LS6/f is a floor-standing loudspeaker system that combines a modern aesthetic with the open, uncoloured sound you'd expect from a Graham Audio system.
The integrated plinth provides a flow-optimised path for the airflow from the port, reducing distortion at high outputs.
The LS6/f uses the same custom drive units as the stand-mount LS6 and has an optimised crossover network using premium quality components to integrate the acoustic output from both drive units and equalise the overall response for optimum performance in free space. A switch on the front panel adds 1 or 2dB to the tweeter level, which might be advantageous in certain acoustic environments.

The BBC LS5/9
The LS5/9 is a high quality studio monitor that was designed by BBC Research and Development and featured a brand new 8 inch bass/midrange drive unit that was developed entirely in-house and constructed using the best materials available at the time.
Designed for use by the BBC in smaller studios and control rooms, the LS5/9 is a close sonic match for the larger LS5/8. Equally at home in a domestic setting, the open and expansive mid-range reveals previously unheard details from even the most familiar recordings.

The LS5/9f
A development of the famous BBC LS5/9, the LS5/9f is the perfect choice for those who prefer floor standing loudspeakers over the traditional stand-mount form factor.
However, the changes aren't simply cosmetic. Yes, this model uses the same handmade bass/midrange driver from Volt along with the 34mm Audax tweeter as the regular LS5/9, both selected to the same tight tolerances. But the larger cabinet allows for increased bass extension and greater dynamic range.

The LS8/1
The LS8/1 is Graham Audio's take on the classic 8 inch bass driver in a 2 cubic foot box format, as used by many designers over the years, including our own Derek Hughes (and his father Spencer, who of course designed the BBC LS3/6).
Some earlier models suffered from reliability problems because of limited power handling. Some had a bass response that didn't work optimally in domestic listening environments. But many were able to give hi-fi enthusiasts their first taste of studio monitor neutrality, especially through the midrange, thanks to the "thinwall" cabinet construction and the innovative - for the time - use of plastics for the mid-bass driver diaphragm.

The BBC LS5/8
The LS5/8 is the BBC's flagship design, and was developed because of the need for higher sound pressure levels and greater transparency and consistency than the ageing LS5/5 offered. This was the first BBC loudspeaker to use a polypropylene diaphragm which, being lighter than Bextrene, offered greater efficiency and lower colouration. A carefully researched cone profile enables the unit to work successfully well into the midrange.
After many months of intensive development, the Graham Audio LS5/8 refines the concept further. Designed in conjunction with Derek Hughes and Volt Loudspeakers and manufactured under license in the UK, it features a unique 12 inch bass/mid unit that is married to the same 34mm Audax tweeter that is used in the LS5/9.
As with all our BBC monitors, the cabinet is a finely tuned structure that uses high quality birch plywood and hardwood batons. The 12mm panels are mass-loaded to move resonances away from the midrange region and Rockwool is used in preference to cheap foam for air damping.
The design retains the same midrange clarity and balance of the LS5/9, but offers an extended bass response and greater authority at high level in larger rooms. The continuity of sound quality between the two designs means that engineers can move between the two different loudspeakers with complete confidence during the recording and mastering process.

The LS5/5
The LS5/5 is a large three way monitor designed in 1967.
A 12 inch drive unit handles the low frequencies up to 400Hz. At this point, an 8 inch midrange takes over before handing over to the 1 inch soft dome tweeter at 3.5kHz. Overall, the frequency response is flat to within ±2dB from 40Hz to 20kHz.
Straight away you'll notice that the bass and midrange drivers are mounted behind slots on the front panel. This feature is highly unusual today, but it works to control the off-axis response of the drive units which results in a smoother response through the crossover regions in typical listening environments. Not surprisingly, we get a lot of questions about this, so we have written an in-depth article explaining how the slots work.
Naturally, this is a BBC-style "thinwall" cabinet, where the relatively thin panels are mass-loaded to ensure that resonances are moved away from the critical mid-range region. Rockwool provides air damping. Hand-matched veneers are applied and finished to a very high standard. The grille is carefully designed to minimise diffraction effects and is held in place by concealed rare-earth magnets.

The LS5/1
The LS5/1 preceeded the classic LS5/1, and used commercially available drive units from Plessey and GEC. Two tweeters were required to achieve the required power handling. In the case of the LS5/1 - but not the OB version (the LS3/1, which was smaller, used a sealed enclosure and placed the tweeters in front of the woofer) - the upper tweeter rolls away at higher frequencies to avoid the acoustic lobing effects associated with two sources producing the same output when the spacing between them is comparable to the wavelength.
The woofer is 15 inches, which is almost unheard of today in the domestic market. Using modern materials and techniques, our unit has greatly improved power handling and bandwidth over the Plessey original.
Of course, with such a large woofer, "beaming" is a serious problem at the upper ranges of its operation. The BBC's answer to that was to use slot loading, as many have already seen in our LS5/5. This approach really helps to improve the off-axis response, making it possible to use larger drive units in typical domestic listening rooms. Much more information about how this works can be found in this in-depth article.
The floor-standing cabinet uses the traditional BBC approach of (relatively!) thin panels that are mass loaded to move the resonances down away from the critical midrange region. High quality hand-selected veneers are applied, and the grille is held in place with concealed magnets so can be readily removed if desired.

The LS5/5F
The LS5/5F is a development of the LS5/5.
Using the same drive units and crossover points, the larger cabinet results in even more bass extension - reaching well below the -2dB point of 35Hz in practice.
We have also taken the opportunity to add the tweeter level control to the front panel. This allows the tweeter level to be increased or decreased by 1 decibel, and while the effect is relatively subtle with most programme material, it has proven to be a really popular facility that allows the listener to fine-tune the speaker to their listening environment.
In common with the stand-mount LS5/5, this model uses slot-loading to improve the power response of the unit, which greatly improves the behaviour in typical listening rooms. Much more about how this works can be found in this in-depth article.
We continue to use the BBC-style "thinwall" cabinet construction, which uses relatively thin panels that are mass-loaded to move resonances away from the critical mid-range region. Rockwool provides air damping. As with most of our loudspeakers, hand-matched veneers are used and the grille held in place by concealed rare-earth magnets.

The VOTU - Voice of the Universe
Building on the research and development that delivered the bespoke SYSTEM3D - a high quality professional sound reinforcement loudspeaker originally designed for the Royal Opera House in Covent Garden, London - the VOTU brings new levels of refinement and authority to the discerning home enthusiast or professional user alike.
The VOTU uses two 10" drivers which cover the bass frequencies and extend up to 800Hz, where a refined 3" soft dome driver takes over, covering the critical midrange region until 4kHz, at which point the high power 34mm soft dome tweeter comes in to play. The midrange dome is mounted above the tweeter to improve the integration between it and the tweeter.
The crossover network uses high grade capacitors and air core inductors that won't saturate at high power levels. These premium components ensure that harmonic distortion is kept at extremely low levels for maximum preservation of low-level detail.
As with all Graham Audio loudspeakers, the cabinet follows BBC "thinwall" practice, where careful damping of the relatively thin panels is designed to move all colourations away from the midrange area where we are most sensitive to low-level resonances. The sculpted 3-part front panel and high-gloss lacquered finish will suite both classic and modern interiors.
This flagship system can be used with amplifiers up to 1000 watts per channel, and is capable of a breathtaking dynamic performance, while losing nothing of the subtlety and resolution associated with Graham Audio loudspeakers, even when played at very low levels late at night. Truely the best of all worlds!
