Sorry to hear that - did the insurance pay out OK?

Yes, thanks. It was...maybe still is...a GPz900R, the
original ninja, which became regarded as a classic. I got
slightly more than I paid for it, but only after arguing and
sending a heap of evidence of value. All the same, I would
have rather kept the bike, even though it was scary after
the AJS (jampots) and the BMW with *7 suspension units*

Which, of course can happen when some speakers get old and
which can be fixed to some extent by turning the speaker
180 degrees.

I guess...but I've never had an old speaker in my house.

OTOH, doesn't a horn rather slow things down?


Oh dear, that is usually a cue for one or two here to drag
the old 'it's not a proper horn' chestnut out but no,
quite the opposite.

(I have Ruarks and Tannoys on the go here and B&Ws in the
loft- which may be fetched down this afternoon!)

I rather expected a broadside along the lines of "what does
this idiot think he means by slow...".

A long time
ago, I used to play an E-flat bass, and it took so long
for a note to get out that to play anything fast I had to
block its sound out of my mind otherwise I got confused
between what I was playing and what I played a little
while ago. It also carried on playing after I stopped
blowing. That's why they are restricted to umpah, umpah.
French horn players in orchestras must be really clever
to play their more complex passages ahead of time.


No idea about any of that.


Actually I think what happens is that it takes a while for a
big tuba to cultivate a low note and, once it gets it
together, it takes just as long for it to die away. Unlike a
speaker horn, the musical instrument relies on resonance. If
you try to hurry it through a sequence of notes, it gets
faint and farty because there's not enough time to develop
each one. To some extent this is true for most acoustic bass
instruments I suppose.

I guess it takes some practise to get the bottom note out of
one of these before you run out of breath:

One interesting train of thought might be to wonder why
"fast bass" might be a desirable feature of a speaker, if
instruments don't make fast bass in the first place without
getting lost in a woofely blur. Maybe bass drums can be
quick, and I suppose an ensemble can play a fast passage if
they work in sequence.

How does modern "drum and bass" sound on your Lowthers? I
guess it's a musical form facilitated by speakers that
utilise modern materials technology for suspension and
cones.

They have published a rather strange review on that web site. It (one
of just three) said that the PM7s sounded as if they had a blanket in
front of them. Very damning thing to admit.

Are you sure you worded those last two words as you really meant? I
didn't know you were a recent model.


I'm not, I'm a refurb....


Otherwise, of course - why not?


Exactly!

In principle, if a horn couples energy from the cone movement into the air
more efficiently it could cause any cone resonances to die away more
swiftly. So in one sense quite the opposite of "slow things down". But as
usual, the snag is that reality isn't so simple. For example, the horn
structure itself may pick up a lot of energy from the cone/air movements
and have resonances which then take time to dissipate. In effect, you then
may reduce some cone problems in exchange for other - possibly more
serious
ones - with the 'horn' structure.


Couldn't have put it better myself!!

(No, really - I couldn't!! :-)

The B&Ws? Nowt special - a pair of 2003 shelf/standmounters that belonged to

Anyway, they've been down; failed miserably to supplant the Pinkies and are
now in the bottom of my wardrobe awaiting their fate...

See the 'Speaker shootout' thread - you may be missing summat!

I've had old IMF and B&W TLs here and they put out a lovely sound; also old
Wharfedales and one or two others that have all sounded very nice. Not to
say some of the brand new speakers I have also had didn't sound OK - again,
a pair of really modern Wharfedales were very good, I recall....

Nobody ever got a broadside from me for a reasonably polite post!

Ooh, there are times (almost anytime, actually) I could power one of those
*bigly* and 'breathing' wouldn't come into it! :-)

Drums come over very well actually. A while back my old pal Shiny Nigel said
that the drum sound on one of my fullrange speakers was the most ****** he'd
ever heard! I just can't remember the word he used (extension?) and I can't
remember the track now, but he was very pleased with them!!

Earles forks on a BMW outfit? Sounds just like the rig I should have had and
jhave been thinking about for a long while now!

Got any pix?

Forget the 'blanket' thing - that's only some wattock's view; the entire
point of Lowthers is their *clarity*, which is far too much for some!!

The description of the drivers makes it look like they are all exactly
the same apart from the size of the magnets - is that so? (I'm
obviously talking within a model range here).
