Win! HEDD AUDIO Type 05 A-Core monitors

Feeling lucky? Enter for your chance to win a pair of Type 05 A-Core monitors from HEDD Audio, a prize worth £1150$1404!

From their headquarters in Berlin, HEDD Audio have been making monitors since 2017 – but their pedigree goes back much further! Their founder, physicist Klaus Heinz, has been perfecting the art of ribbon tweeter design since the 1980s, and is singularly responsible for some of its greatest technological leaps.

The company’s latest creation is the A-Core series, which, naturally, uses a Klaus-designed AMT or ‘Air Motion Transformer’ tweeter. This is paired with a custom honeycomb bass driver and twin 100W Class-D amps, to provide a frequency response that extends from 43Hz to 50kHz, with a maximum SPL of 112dB at one metre. When we reviewed the Type 05 A-Core in our August edition, we were hugely impressed, describing it as “an impressive, high-performance, all-analogue studio monitor whose compact size belies its capabilities”. You can read the full SOS review here.
