Graham Audio LS5/8 Loudspeakers | Audio Emotion

Product Description

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 Graham Audio's 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 LS5/8 was originally conceived as an active design, but Derek Hughes has designed a passive crossover that greatly improves on the resolution and imaging of the original design while still conforming to the demanding BBC specification.

is extremely smooth across the midrange and bass, with an effortless dynamic range that only a big, easy-driving bass unit can bring. This is a loudspeaker that might forever been hidden away from the public view and the last of the line of BBC speakers could have just been a footnote in audio's history. Graham Audio deserves great credit for bringing these classics to light.

About the Brand

About us

Graham Audio is a family-owned British company based in Newton Abbot, a small market town in Devon, south-west England. We are passionate about high-quality audio and believe that the classic BBC loudspeaker designs offer levels of neutrality, transparency and realism that are hard to find elsewhere today. Using modern components and production techniques we have been able to push the performance while remaining true to the original designs.

We might be small, but we are proud to work with some of the best talent in the industry, including Derek Hughes and Volt Loudspeakers. Our loudspeaker systems are available throughout the world from carefully selected outlets who have full demonstration facilites, and will support you through the selection and setting up process.

All loudspeakers are hand-assembled on-site. One person is responsible for every step of each loudspeaker made, which includes testing and auditioning. A second person double-checks the completed product, repeating the testing as a matter of course and saving the results for future reference. As part of the test procedure, all completed loudspeakers are compared to our master reference samples to ensure complete consistency.

Company History

The company was founded by Paul Graham, who has spent more than 20 years working in all areas of professional audio, including the recording and broadcast industries, and in live sound and performance. Of all the different approaches, Paul has always favoured the "BBC sound" for both professional and personal applications, but feared that many of the classic designs would be lost forever as one by one the surviving examples gradually failed after many decades of operation. A couple of chance meetings and some long conversations later, it was decided that the only way to preserve this legacy was to seek BBC approval to build them himself.

Happily, our debut loudspeaker - the BBC LS5/9 - was warmly received by reviewers and owners alike, and the BBC LS5/8 and BBC LS3/5 have been equally successful. In addition, our range of bespoke loudspeakers include a high power, high quality passive monitor primarily intended for live sound (the SYSTEM3D) - and from that research programme the floor-standing VOTU was born. The new Chartwell LS6 sits between the LS3/5 and LS5/9, and gives nothing away to those models in terms of dynamics and musical insight.
