Re: Radio sound quality - some measurements
Next, the RP37A.
This VHF Herald is fitted with the large-magnet Elac - the best of them. Some sets were fitted with the same Celestion that the later Sovereign II sets got. The original VHF Herald came with the Goodmans, which we now know is best avoided...
As before, black is the "flat" position (bass/treb at min), and blue is the measurement after tweaking for best subject results.
This is more like it. At the bass end, look at how extended it is! Really quite incredible for a portable radio. And at the same time, plenty of treble extension - it reaches out to beyond 12kHz before dropping away significantly. There are a couple of dips (at 1.5kHz and 7kHz), but dips are far more preferable to peaks. And it's entirely possible that these dips are caused by the cabinet and/or grille.
With the tone controls adjusted, it's flatter between 75Hz and 12kHz than a lot of "hi-fi" speakers that I've measured. A fine result. This is an easy set to live with - and has long been one of my personal favourites.
