♫ A5 VOTT System

 

I started my vintage Altec Lansing A5 Voice of the Theatre loudspeaker project in earnest a year ago now (it’s December 31st 2016 today as I post this update), and I have really been enjoying watching my Altec A5’s evolve.

My vintage Altec A5 Voice of the Theatre loudspeakers having been taking turns with my Tannoy Westminster Royal SE’s in my main music listening system in my living room while I got their crossovers built and dialed in.

The Altec A5’s were intended to provide ample sound for the specific needs of small-to-medium sized movie theaters, so their crossovers need to be redone to adapt the big beasts to a domestic listening environment.

To that end, my crossovers are an adaptation of Jean Hiraga’s superb 16-Ohm crossover design for the Altec A5’s, but with a few modifications in order to tame the 1005B high-frequency horns I’m using instead of the 3dB less sensitive 1505B horns that Hiraga-san used.

The Altec A5’s are impressive loudspeakers that are surprisingly flexible and room friendly, and somewhat to my surprise they have adapted remarkably well to their new home, which happens to be a spare bedroom in my home that I use as a TV room, with the rather small dimensions of 11-feet x 12-feet x 9-feet (ceiling), with a 6′ x 3’5″ x 9′ foyer on one end.

My living room seems remarkably spacious now that there’s only one pair of monster horns residing there!

My TV room has an aging Philips television hung up on the wall so I can watch an occasional movie or TV show, kept company by an equally elderly Oppo BDP-83 Blu-Ray player for spinning DVD or Blu-Ray movies, or an occasional CD.

I have been using the stock power cord on the Oppo, but in a wild hare moment I put one of Mark Coles’ Sablon Audio Gran Corona power cords on it, and the elderly digitizer was completely transformed with a level of musicality & sonics that I never would have thought it was capable of!

I’m using my Leben RS100 line stage with a Sablon Audio Gran Corona power cord, along with my vintage McIntosh MC24o stereo amplifier, for a very happy amplification match with the Altec A5’s.

Belden 8402 microphone cable interconnects connects the Philips TV to the Leben RS100 line stage, and to the vintage McIntosh MC240 stereo amplifier. Duelund DCA16GA interconnects connect the Oppo BDP-83 to the Leben for listening to CD’s.

As always, my hi-fi systems are in a constant state of flux, but that’s where things are with the A5’s at the moment.
