"New" Tannoy System 12s

I just bought a used pair of System 12 Mk. 1s.

I have 3 burning questions:

1. Does anyone know where I could find a manual?

2. Also, apparently I need help in how to bi-wire these guys.

3. My amp (really a surround sound receiver) is rated at 110 watts RMS/channel. Some folks have told me that I will not enjoy a balanced frequency response until I invest in a more powerful amp (250-400 watt). Their contention is that my puny amp will have issues moving that big heavy magnet, and the low end will suffer as a result. Any thoughts on this theory?

Thanks (in advance) for all comments!!

I'm far from an expert, but I can tell you not all "watts" are created equal. Secondly, a receiver is a compromise. (As one salesperson I talked w/ a very long ago called them "toasters".) You're not going to the best out or know what your Tannoy's are really capable of w/ a rec. I hope you don't end up on the Audiophile merry-go-around. But an amp will lead to other things...

I don't know about your particular model, but most Tannoy DC drivers are at least rated at 90db sensitvity. My 1975 vintage 12" HPD's (though they are in custom cabs with custom crossovers), are driven beautifully by a VAC EL 34 tube amp at 35 Wpc. Even my Sophia Electric Baby amp, at 10Wpc, plays very nicely, at fairly high volume.

For tons of info and support, go to Hans Hilberink's Tannoy site(just Google it)

Enjoy,
Dan
