It will even survive the crowbar protection system (until that
protection system is destroyed).

Why would anyone design that amplifier and say it is for music? One of
the most pointless specs I've ever read. You're just ****ing your
money away if you buy that.

Because of the Australian fashion for designing speakers with impedances
that drop to zero at the crossover frequencies.


**I should also mention the (in)famous Gale 401 speaker. UK designed and
built, with an impedance curve dipping to around 1.8 Ohms in the
mid-bass region. In fact, the designer of the above-mentioned amplifier
owned a pair of Gale 401s back when they were first released and was
part of the reason why he designed his amplifiers with such prodigious
current ability.


Gale never made much of a mark here. They pretty quickly got taken
over and became an own-brand label for Richer Sounds.


**Funny about that. The Gales have acquired something of a cult status
over here. 40 year old examples command quite respectable prices.
