Well, the Vifa is often recommended as an upgrade for the T27, so I
really wouldn't be too fussed about the impedance difference. Just be
prepared for it to be a bit on the loud side, though - you may need a
series resistor yet.


That I don't get - a higher impedance will result in a *louder* sound...??



Now, is '3' going to represent a big problem crossoverwise? - I'm
intending
to use the original Ruark crossover and the T27 is 8 ohms, as you can
see/already knew....

Nope, don't worry about that.


OK.


A shrug is all you will get from anyone. For sure they are going to
work a sight better than a busted pair of Vifas - although it may be
worth your while seeing f they can be fixed. They're rated and worth
money.


Glad you said that, I was going to *investigate* the innards at the end of
all this!!

Carpetting the Ruark boxes now - the messy bit, I stick it in with Unibond!!

(*Insides*, of course...!! ;-)

No, all other things being equal, a higher impedance will draw less
power and so produce a lower sound level. One reason why 'speaker
manufacturers like to use 6 ohm drive units is that it gives them a bit
of extra sensitivity over 8 ohm rivals, but without becoming too
strenuous a load for more modest amplifiers which they could well do if
they went for 4 ohm drivers.

Sorry - got the which and the what back to front. Softer - so you
probably won't need those resistors.

OK. Just finished (I'm knackered!) and here is the lineup now:

http://www.apah69.dsl.pipex.com/show/lineup.JPG

Rob's tweeters are in the Sabres (top) which now have their own woofers back
in and their own crossovers. They have been fully carpetted, the (larger)
T27 tweeters have been let in and new 'lambswool' stuffing put in.

The Meraks (bottom) now have Rob's woofers, their own tweeters and their own
crossovers (untouched) with no other work done other than 'easing' one of
the holes for a 'tight woofer'....

I've literally only just got in and have heard maybe 5 minutes of A/B'ing of
both of them and I think they both sound very good - different, but still
good. If you are about Don, nominate a track I'm bound to have and I'll grab
a snatch from each of them for a 'comparison' (as far as is possible) -
otherwise, it'll be a Milladoiro track!!

OK, Don's sloped off for an early night!

(Bless.... :-)

Here's the Milladoira clips I threatened then, on this setup:

Quite different really, but neither is unpleasant in its own way (recording
restraints notwithstanding) and either is easy enough to get used to....???

(Must be me - WTF do I know..?? ;-)

Sorry Keith - I'm away from my usual setup right now. I'll have a
listen later.

No worries, I gotta go and cut a 50 foot tree up now - it's on its side and
hanging over the neighbour's garden! (Not here...)
