3rd Power – Amp And Triangular Speaker Cabs

3rdpowerWeird, eh?  This is the 3rd Power HD100 amplifier head sitting atop three separate HLH 312 speaker cabinets.

The HD100 is a US-made, 100W, all-valve amplifier head.  It’s built with point-to-point construction and has two, foot-switchable channels.  A ‘voicing’ switch can toggle from ‘smooth’ (classic, vintage tones) to ‘bold’, which we’re told provides a more lyrical quality.

Each of the HLH312 speaker cabinets (and remember, there are three in this image) contains three Celestion Vintage 30 speakers.  3rd Power claim that the design of the cabinets eliminates the beaming and comb-filtering associated with regular, rectangular cabs.  They reckon that having four speakers in a single cab, producing sound together can lead to phase distortion and standing waves – and therefore, degraded sound.  In addition, the sound from a regular cab changes based on the listener’s position.  The 3-speaker design (in this 3-cabinet configuration) aims to overcome this and to ensure an even spread of sound rather than simply beaming it right  at one point.

I can’t help being reminded of the Watkins Dominator when I see this image.  3rd Power are making some big claims.  I’m interested to see how they pan out in real life.  Will we see walls of Marshalls being replaced by triangular towers?
