Tube subwoofers?


Does such a thing exist? From logic, adding a subwoofer to a tube system means adding an SS amp to the system, right? SS, producing the best bottom, makes sense for powering a subwoofer, but I was wondering about tube subwoofers. Does anybody use one and how does it work for you?

I've just been listening to the Seventh Veil loudspeaker system with Tom Evans' Soul (tube) Power amplifiers.

Initially the Soul amps were just used for the full-range speakers and an inexpensive solid-state power amps were used for the bass.

Changing to Soul amps for the subs as well as the mains made a dramatic difference top the bass, integration, tone and timing.

Of course the Soul amps have a far better bass end than many tube amplifiers and the solid-state amps used were relatively cheap and could, no doubt be easily surpassed.

Still, this listening session changed my ideas about amplifying subs (particularly with the Seventh Veil speakers). Ideally I would now go fo tube amps throughout, with the sub amps matching the main amps if possible.

Steve - You wouldn't be selling Seventh Veil speakers by any chance? Or ultimate power sources? Or kleenex boxes?
You could make a SET with an 833A to power a subwoofer with enough power. Use the high voltage transformer output from the power supply of a discarded microwave oven and a full bridge rectifier consisting of four murcury vapour rectifiers. The output transformer might make steel cabinets and desks slide across the floor and you will want to have a well ventilated cabinet that will keep the 2500 volts you will be giving it where it will not be accidently touched. Some people at GR Research built one, but I think they did it to be funny. However it worked.

Personally, I almost became so disappointed with subwoofer amplifiers going bad in a year or less that I almost built such an 833A monstrosity. Fourunately, Audio Express came up with a sensible subwoofer kit that perfectly integrates with my 45 SET amplifiers.
