Luckily, I'll not be removing them and have no small children.

I do own a pair of Walnut Dentons by Wharfdale, which still sound
quite good considering their age.

I alos have some walnut veneer Denton 2s but the rubber surround of one of
the woofers has become detatched from the aluminium chassis (the glue has
gone brittle and let go, the surrounds themselves are fine). Consequently I
haven't heard them for a few years, they're in the 'round tuit' category but
as I'll likely have to move into a smaller home next year will probably be a
bargain for someone. The pink acetate coned tweeters are a real curiosity.

are of the sprung kind, and recessed, but then some idiot put the
port on the back. Like huh?

I guess this is what you often find when they have a name as tacky
as Skytronic, which sounds like it ws made up in about 10 seconds
roungd the pub.

Not to say that they sound bad, but that their placement is
critical. Brian

The term "bookshelf" in this context has come to tend to be used
to mean "small enough to be placed on a bookshelf".

I have a pair of speakers that were sold as Bookshelf speakers by
the manufacturer - Goodmans Mezzo SLs. They're ... 530 x 320 x 250
deep (but
do have their small port on the front baffle). Even back in the
1970s when
they were made "bookshelf" was a very loose term that had very
little to
do with an actual bookshelf.

From a review in the March 1975 issue of Gramaphone:
"The Mezzo SL is described as a bookshelf speaker, but is
moderately large
for such a description, measuring 21 x 12i x 10 inches."

Putting a boxed speaker close to a wall generally boosts the bass
output. Using an open port into free air also generally boosts the
bass output. Thus a designer might design the speaker to use one
effect *or* the other, depending on if the user chooses to place
it against a wall or not.

That same review says this of the Mezzo SL:
"Connections are made via, a recessed box which helpfully carries
both a
standard 2-pin polarised DIN male socket and a pair of 4mm (banana
plug)
sockets. The recess allows the speakers to be placed flat against a
wall,
and such positioning is likely to give just the level of natural
bass lift
which bookshelf-size speakers appreciate."

So it may be that they had more "tech knowledge" than you think.
OTOH it may have been a clueless / fashion choice on the part of
the maker. Jim

I bought some fairly cheap bookshelf two unit speakers, and they
sound fine as long as they are at least a couple of foot away
from a wall as they have a port in the back of the cabinet.
However they are described as bookshelf design, and of cours as
most bookshelves are on walls this somewhat makes the port at
the rear a silly design. Not only that but they have the keyhole
screw head retainers and recessed terminals so you can hang them
on the wall. Do this and they sound like portable radios.

This is what happens when those in charge of selling stuff has no
tech knowledge of speaker design! Now if they had made the port
in the side or the bottom.... or the front for that matter! Brian





According to their brochure, Skytronic specialise in DJ and
karaoke equipment. You didn't mention the model number of
the speaker you have. But they have a bookshelf model that retails
at Euro 55. I don't think one can be too picky at that price:-)
