Thanks - it actually isn't saying it dislikes the room ratio - simply that I'm not complying with this rule... "Avoid 50% room length/width (null points). Sweet spot at 38% from front wall:2.85 m"

When this says 2.85m from front wall I presume that means the wall the speakers are on?

This is the room looking from one end and the sofa is more or less where the desk chair is - I think this is ultimately saying I need to listen even more in the nearfield.

Actually, I didn't realise that this was available as a free download - give it a go:

It allows you to move the speakers and listening points around and shows the frequency low points.

To have a smooth frequency response you probably need to be nearfield as you say, or much further back. Don't have time to play around with the speaker position for you at the moment - currently sitting in a Teams DTM on a property waiting for my turn to talk. They are currently discussing the fill time on a 1100 litre bath in the guest bedroom that will probably be used twice a year!

If that's reflectopron in the far away window, thank goodness for that horizontal window frame element.

I should also add, I'm all for purity of signal, but odd room shapes can really benefit from some EQ correction, which tends to only exist in the home cinema world. In a stereo setting we've had good results using a miniDSP between the source and amplifier.

I did have to find the original image on my iphone to zoom in to check as it does look suspiciously like a naked torso but safe to say I am wearing clothes!!

What's a normal bath? Somewhere around 100 litres I assume?

The bath is filled with something other than water, the client is Baron Harkonnen AICMFP

Yes it really sounds like its stretching the concept of a "bath" as opposed to a (still quite large) plunge pool.

No I do need a rug - there are going to be a lot of reflections from the in-built cupboard doors in the shelving either side of the speakers though, plus the rug won't do anything for the bass issue.

I prefer banging when it’s rug-less, and thanks for the flashback to Christian Horner’s finger pic! You sure you’re not just wearing a cape!?

I’m sure you can find a geeky, turntable seller in London who loves these kind of problems and will try several speaker set ups.. there’s a chap in Windsor that does exactly that, but his final figure was several tens of thousands, so I just bought a load of Sonos instead - trueplay ftmfw (especially after more than 2 decades of zero noise cancelling flying, loud bars, thighs etc destroying my poor ears)

On the basis that a small water butt is 150+ litres I’d assume it’s still much more if you want more than just your legs covered

Same as a 6 seater hottub.. giggty

According to teh googles:

An average standard household bathtub has a maximum capacity of about 140 to 200 liters. However, because the water level only needs to be about half-full (and the bather's body displaces the water), a standard bath typically uses about 80 to 120 liters per use.The exact capacity varies depending on the type and dimensions of the bathtub:

Standard Straight Bath: 1500–1700 mm long, holding roughly 140 to 200 liters.

Freestanding Bath: 1500–1800 mm long, holding up to 250 liters maximum.

Shower Bath: 1500–1700 mm long, usually holding 160 to 220 liters.

Corner Bath: 1200–1500 mm on each side, with a total capacity of 200 to 260 liters.

Jesus, what’s doing their hot water????!!! Average invented cylinder is usually 120-150l in an ordinary house, maybe up to 250 or so in bigger places. At 1100 litres it’ll need a huge amount of hot water input and probably need a circulating heater like a hot tub just to maintain temperature

I don’t believe this

the standard fill for a bath tub is 2/3rds right? I can’t imagine 8 of those 20l cans filling that!

I'm imagining somewhere with an 1100 washing facility has more of a plant room than your typical domestic heating system...

Right - now we need a video of you performing a measured fill of your bathtub.

I haven't looked closeley at it as we're just changing setpoints over Bacnet rather than controlling the kit on this one, but the plant room is about 5m x 4m, so I expect a fair size tank(s) going in!

jamcg has prompted me to check now -

64mm incoming mains, three 90kW boilers, two 600L hot water cylinders, 4500l storage tank, cold water booster set to supply 5.0l/s at 5 bar.

You'd be happy with 270kw output in a car

Back to stereos, we're having a bit of a clear out in the stores if anyone would like to make an offer -

Pair of Meridian M6 in black with speaker controller
Sony VPL-VW570ES, only 8 hours use from new
3 x B&W CT7.3LCRS (a few marks)
4 x B&W CT7.5 LCRS
2 x B&W CT subs (12 I think)
B&W sub amp (need to check model)
1 x Yamaha CX-A5200
1 x Arcam Stereo reciever (FMJ 250 I think)
