I like the look of these, but i've got 2 questions.
Will they stand without the plinth (I've got limited space and I'm wondering if I would really need it)?
The review says it can be bi-wired, but what's the point?

Hi Pedro

They will stand without the plinth, with or without spikes, but it wouldn't take much to tip 'em over. If you've got kids, dogs or likely to have any parties, I'd say you'll need the plinth.

There are various reasons for bi-wiring, though mostly it offers a quick way of upgrading your system by improving the sound your speakers can offer. We've got a full how-to and why-you-should guide going up in the next week or so...

The point is to squeeze a little bit extra performance for no extra cost. I have bi wired a few times and got improvements that can be heard. Only do it if you have the time.
Beware biwiring if u have a 'loved one'or other who might reconnect a loose wire on their own. You risk loss of the whole speaker unit.
Incidentally, the improvements i got were on cheaper speakers than these. I have never tried bi amping as this is a more complex and altogether more costly business.
