The above specifications show why these speakers are capable of such extraordinary transient performance and yet reveal such intimate detail in the music. This fidelity is possible due to the fine tolerances and light weight of the driver weight and voice coils.
The Grand Epitome Tower Reference features heavy lead lining to all exterior surfaces. The same heavy bracing is used, but all areas between the bracing are covered by a unique sandwich lining. Heavy acoustic felt is used to separate the heavy lead sheet from the cabinetry. A further layer of heavy acoustic felt is placed over the lead and the entire sandwich is stapled to the walls of the cabinet. This result is what is effectively a box within a box. Wrapping the outside of the speaker is similar to knocking on a brick. This totally inert cabinet construction results in the ultimate sound reproduction.

Dear Greg,
As you're aware I've been using the Osborn Epitome Grand Reference now for about 6 months on a regular basis, thus I thought I'd give you an update as to their ongoing performance.
During the last 6 months many guests have had the privilege of auditioning the speakers in our living room, and to date no one has left disappointed, all who have listened, have gone away thinking their own systems pail into insignificance when compared to the sounds emanating from the Osborns. The entire audio spectrum is fabulous with a definite sense of authority, which was completely absent from my last set of speakers. The bass is incredibly deep and powerful, not in a overpowering way, but entirely dependant on the quality of the recording. If the CD was recorded with heavy bass then that bass translates to the listening experience. The top end (Tweeter) is so clear that listening to any other speaker now just makes me want to leave the room. Greg, That tweeter is one of a kind, it should be mandatory on your entire speaker line-up, cost aside.
The colour of the Speaker has settled in nicely, Tasmanian Blackwood is superb and complements the room beautifully, in fact a few guests have made a comment to that effect.
On a final note, I've come to recognise the only weak point in my system, now stems from my old Musical Fidelity CD player. Once, enough spare entertainment funds are available, the Audio Aero Capitole 24/192 CD player will complete the musical experience.
The Epitome's are truly magnificent, I've heard many speakers systems over the last few years, but the last six months only vindicate my selection choice.
Yours Sincerely,
Viren Khatri.

Hi Greg,
It has been eleven (11) days since I took delivery of your magnificent speakers. They really are a revelation in just how much I have been missing in fine musical detail from my previous speakers. The clear separation of individual instruments and notes is truly amazing. I certainly now understand the term “want to listen longer”, it certainly applies to your speakers.
My wife and I are both extremely pleased with the Grand Epitome Reference speakers. The ‘look’, fit and finish of these speakers is truly world class and they are certainly comparable with any hi-class piece of furniture. How do we think they sound? Beautifully natural and ‘life-like’ is the impression that best describes how we feel about them. The sound stage and imaging these speakers impart is a wonderfully soothing experience, it is though you are ‘there’ listening to a live performance. We find ourselves listening with a smile! ( to think they will only get better – awesome!)
I can honestly say “we are proud to own them”. It has been a pleasure dealing with you Greg.
Cheers
Murray Ellison.
