Speakers used in DAB Portable radios

[Mark Hennessy]

Compared to FM, DAB broadcasts certainly can do, technically, but they rarely do in practice. Not significantly, at least. The Optimod is alive and well in DAB-land, and is an essential tool for stations that employ "less qualified" operational staff. Of course, a reduced dynamic range gives the MPEG encoding an easier ride, which is important given the low bit-rates in use.

So in the context of a 3" speaker in a portable DAB set with only a couple of watts behind it, it's hard to think that is the reason - but anything is possible, of course.
