What do you do with a *lively* room?
 

You use it!

I've been meaning to throw a pair of OB speakers together for a while (had
the ideal drivers kicking about for ages - Visaton B200s) and never got
round to it, but I was sent a pic of some nice OBs the other day and they
got me thinking.....

They were stood out in the middle of a room which I thought wouldn't have
been doing them any favours and it caused me to wonder what slotting a pair
into the corners of my room and *using* the 'liveliness' to boost the bass
would work like? Add to that I've been falling over a bloody great, *heavy*
piece of board (white plastic faced 18mm MDF) in my garage for a while, so I
duly threw a pair together - it took about 3.5 hours and the only scrap left
over from a piece of board 54 x 48 inches was two 48 inch lengths about 1
inch wide and the circles from the cutouts for the drivers!!

So in true Show N Tell tradition*, here's the story:

And some shorter samples from a fairly weedy 'test CD' (it's French - what
do you expect?) which, I think, demonstrate superb clarity - headphones will
give you a better idea but ignore the 'heartbeat' which seems to have crept
back into the equation.....

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.

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.

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?

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!!

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

that a suspended type can absorb a deal of the bass energy.

If you ask because there's a channel imbalance in favour of the left
channel, that's down to me (my fault for not taking more care to set the
levels properly!) - I set the levels by eye and let the recording run for
the duration of the CD (one take only). Unfortunately, SoundForge doesn't
let you see the waveform 'til you stop recording - as that was about an
hour's worth of *real time*, I wasn't about to do it over!!

My room is small - summat has to go in the corners...

I wouldn't disagree with any of that, but would say my suspicions do seem to
have been borne out by the fact that the OB speakers sounded kinda OK (but
not stunning) when I plonked them down in front of the other ones, but then
*did* sound stunning when I shunted them into the corners. (Not my say-so,
but I hardly dare mention who did say.... ;-)

The *clarity* is the best yet, but I haven't actually had time to listen to
them other than on the move/while doing other stuff. Depth, even when
standing over them, is quite amazing. I've posted the samples, it either
shows in them or it doesn't - I've since made better-recorded samples, but
only of stuff I have probably posted before...

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.
