HARBETH: Spendor SP 100/R2 and Harbeth 40.1 – impressions?

Where I am, it’s difficult to audition these two flagship speakers side-by-side or at home, so opinions/impressions from anyone would be most welcome. Feedback on other forums is that the Harbeth may be marginally the “better” speaker, but I’m not convinced. Matching amps would likely be from MBL. Please click HERE to dip in and […]

ROGERS LS3/5a speakers Q&A

At present I listen to the 11 ohms Rogers version of the above speaker. Generally I am pretty happy with the sound. I wonder if there would be any benefit in going over to a newer design from Spendor or Harbeth, perhaps a slightly larger enclosure ( my listening room is 9 X 11 feet)?. […]

CLASSIC KIT: What is the attraction?

Whilst my recent additions are for a secondary system, they certainly are competitive with today’s offerings at a corresponding price point (well, I believe so) albeit not likely to replace my main system. I could so easily have popped into Sevenoaks or the Classifieds and put together a middle of the range system but just […]

SPEAKER DRIVER TECHNOLOGY: A planar ribbon is fundamentally different than an electrostat and, because of that, they sound quite different too

In both types of drivers, we start with the same sort of plastic substrates like Mylar or Kapton, but there the two radically depart. To make a ribbon driver we need to layer on a thin sheet of copper in the form of a coil, then add tension to this diaphragm and suspend it between […]

CROSSOVERS: Types of resistors for crossovers?

Dear Colin, I have just fitted stock 2R7 Panasonic 0.1% metal film resistors to replace the “green” 2R2 wirewounds in series with the Millennium tweeters in my WD25Tex speakers. I expected a change ( a bit warmer) but was not prepared for such a drastic change – is this due to the 0,5R increase or […]

Q&A LOUDSPEAKERS: What are the advantages of low-sensitivity ones?

  “Scuse my ignorance, but given the fact that Hi Fi is all about gains and losses in an endless spiral of compromises and ‘more of this means less of that’, can the Wam-gurus please explain what the benefits of low-sensitivity speakers are over high-sensitivity models? The benefits of high sensitivity over low is obvious, […]

Where for the sub 50Hz content a planar dipole system was utilised. Nothing new you may say – the […]

Howard Popeck ….. In the early 1980s at Subjective Audio Ltd I took a pair of these in part exchange against a pair of Lentek Monitors, transmission line; a Bert Webb design. Those Lenteks, an overlooked ‘classic’ were exceptional and a substantial upgrade in both performance and cost (and size) to the Clyde’s. Those Clyde […]

SO, NOW YOU KNOW: Distorted speakers

Ever wonder why speaker manufacturers don’t list distortion as one of their measured parameters? Me too. To my knowledge, there’s not even a standard by which to suggest acceptable distortion. Yet, try that with the electronics that drive those speakers and howls of protest drift up through the rafters. Do we not care what level […]

BOWERS and WILKINS: Dr. John Dibb interview
