That I don't get - a higher impedance will result in a *louder* sound...??
Sorry - got the which and the what back to front. Softer - so you
probably won't need those resistors.

OK, that's the gamble I took, but the first pair are still on and really
do sound good - I might grab a snatch off 'em and post it later....

I've just gone to switch over to the radio (CD's finished and I'm off down
the garage again) and, as I was passing, twigged the bloody speakers that
have been on all this time while the CD was player were my bloody
*Pinkies*!!! (Amp's got A and B buttons for speaker output switching!)
:-)

Anyway, I switched over and yes the newly-fettled jobbies do sound good but
it means I haven't really heard them yet!
(Couldn't fekkin' script it could ya, but what a nice reaffirmation on the
Pinkies - even better than asking the milkman!! :-)

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!!

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.

Apart from good old Wilmslow, drive units including tweeters can be
repaired/reconed by
http://www.loudspeakersonline.com/re....new/index.htm
They say a typical tweeter recone costs £30. Interestingly, I can't find
any reference to the D25.TG-85 tweeter on the Vifa web site, so maybe it
was produced only as an OEM item.
I mentioned elsewhere Ruark used to 'voice' all their bought-in drivers and
had them made to order (I was told) and so they would be 'non catalogue'.
(Can't see Dynaudio playing ball though...??)
Love the 'Recone Lab Workshop' pic in the link above - quite different to
some of the 'audio ********s' I've seen (and my garage)....!!

OK, Don's sloped off for an early night!
(Bless.... :-)
Here's the Milladoira clips I threatened then, on this setup:

(Sabres on top...)
http://www.apah69.dsl.pipex.com/show/Merak%20A.mp3

http://www.apah69.dsl.pipex.com/show/Ruark%20A.mp3
http://www.apah69.dsl.pipex.com/show/Ruark%20B.mp3
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...)

At least your judgement didn't let you down - if it had been 'fit for
skip' a rethink might have been in order!

Yes there were tears of joy and relief when I realised my mistake!!
:-)
Interestingly, the two pairs of 'refurbished speakers' sound very different
(I have my own preference) but it is easy to forget it when listening to a
recorded TV programme, which is all I've had the time to do so far!! Kinda
confirms that the 'right' speakers for most people are the ones they have
got used to and goes some way to explain why so many people seem to be
seeking (or keeping) the speakers they had some decades ago!!
It is very much my experience that you can get used to anything
(almost!) and then *that* sounds right whereas anything else different
(even something measurably better) sounds "wrong". However, living with
the "wrong" sound for a while, that then takes on being "right".
In Broadcast, people have been using the Beyer DT100 headphones for
monitoring for over 20 years. They are clearly flawed, but people go on
using them as it's what they are used to and any change is disturbing.
I had one experience in particular some years ago with a pair of Canton
'speakers, I don't remember the model number, but they were their top
model at the time. The sound for me was intolerably bright, screamingly
so, but I lived with them for two weeks. At the end of the two weeks I
was finding them quite pleasant, and when I returned to my normal
'speakers (Meridian M2s) they sounded terribly dull for quite a while.
I also spent an evening with a pair of large Magnaplanars who's bass was
very boomy to my ears. However, by the end of the evening, it didn't
seem so bad. I wonder if this is what's behind so many reviews of
transducers where the reviewer said they sounded so much better after a
period of "running-in". I don't think it was so much the equipment
running-in as the reviewer's ears getting used to it.
