Keith,

As one who *does* have a lifetime's experience of audio (and I'm only now
realising how little I know)there's nothing new under the (audio) sun.
Corner enclosures were very popular in the late '50s and '60s in part for
the reasons you state: i.e. using the room corners to boost the bass, but
also to keep them out of the way of furnishings. It was hard enough for
people to find room for one large 'speaker, but when stereo came along,
finding room for two was difficult. The WAF was as alive then as now.



Serge, no-one is more aware that there's 'nothing new under the (audio) sun'
than me - my amps date back to the 20s and 30s (design) and my speakers
feature drivers that have been in *continuous production* for the last 50
years in a design probably just as old!!


However, putting 'speakers in the corners won't make much difference in a
live room over putting them elsewhere. The problem with a live room is
reflections, which affect the mid and treble. Bass sees hard walls
whatever they are covered with unless you take special steps to create
bass traps. However, using single drive units, the treble will beam more
than using separate dome tweeters, and angling them as you have will at
least help keep the treble away from the walls.


Yes and the angled sides allow the air to move freely - I'm back to
thrumming doorframes here...!!


I have just received a copy of the 1959 Audio Year Book and a copy of the
July 1959 American "High Fidelity" magazine and they are full of weird and
wonderful enclosures trying to make stereo acceptable domestically.

In spite of my long teeth, what's an OB 'speaker other than Outside
Broadcast?


Open Baffle - see the view down the back:

Also this, just to prove I can still do *handheld* at 1/8 of a second!!

Thanks, I'd forgotten about open baffles. However, what you have isn't
really an OB if you put them in the corner. If it fits tightly in the
corner it will approximate to a sealed box, sometimes referred to as an
Infinite Baffle, but as the fit isn't likely to be airtight, you will
have some gaps, so it will work to some extent something like a
Bass-reflex cabinet, but with very indeterminate performance. An OB
needs to be clear of the wall, or sealed to the wall in which case it is
an IB or, if vented, then a bass-reflex. Wharfedale used to do a
sand-filled open baffle with an upward firing tweeter, designed for
free-field siting.

You really should try a corner horn or Transmission Line someday.
