Refoaming AER vs Lowther speaker driver units
For many years I've been repairing Lowther units, refoaming and sometimes repairing lead-in wire connexions and voice coils. Sometimes I'm asked to repair AER units and a number of years ago had no problems with a pair of MD units, but recently came a cropper on a pair of BD2s. Unlike the MD units w...

Re: Seminar 6th May - The Importance of Tuning for Better Performance
It's not off topic at all. The assumption that is made is that all notes should be equally spaced. Then they are not in harmonious relationships in musical chords. What has really happened is that the equal spaced system has been convenient to tuning pianos to make them sound evenly glossy. A modern...

Re: Seminar 6th May - The Importance of Tuning for Better Performance
I think that perhaps a citar player might be coming on 6th May. It should bring a lot of interesting people together.

Re: Speaker help required...
The real thing that needs to match at least is the efficiency . . . and the impedance of course. But voice coils can be fun - here's a nasty little repair I did for someone recently: http://www.audio-talk.co.uk/phpBB3/download/file.php?mode=view&id=6244 http://www.audio-talk.co.uk/phpBB3/downloa...

Re: Seminar 6th May - The Importance of Tuning for Better Performance
That's a really interesting video. I'm not sure that the guitar is very different although there may be something either in tuning the strings in perfect fourths or to the frets, but most importantly in the singing which seems in close harmony almost as Barber Shop with a very pure sound in places. ...

. . . the importance of the hundreds of notes that live between the flat third and the fourth. ;-) http://www.audio-talk.co.uk/phpBB3/download/file.php?mode=view&id=6240&sid=80bb646b1518cd881b6190d78790f69f http://www.audio-talk.co.uk/phpBB3/download/file.php?mode=view&id=6241&sid=8...

Seminar 6th May - The Importance of Tuning for Better Performance
http://hammerwood.mistral.co.uk/tuning-seminar.pdf From time to time people ask how music affects our minds . . . but I ask rhetorically "What is music?" It's a collection of vibrations which are either together, as multiples and as one sound, or not together, so giving contrasts of certai...

Re: This phase thing
On tuning of pianos I'm advocating systems which happen to be historic that use numbers of exact pure 3:2 fifths. This puts many notes of the scale exactly on the harmonics of lower strings, with numbers of near pure thirds or sweeter thirds than we're conventionally used to, and enables the instrum...

Re: This phase thing
WOW! It's really wonderful to see the enthusiasm of exploration on this subject - but to be perfectly honest, as Fourier transforms would indicate, the absolute phase is - to me - inaudible although possibly obstructed by tinnitus. Upon phase change you're actually introducing a new frequency set as...
