A challenge / scientific research involving Bub

GET THAT TELLY ON SOME MANA FFS BUB!!!!

 

I guess everybody who sees Bub's room suggests this. Anyway he doesn't need to mess about from a hifi pov.

Actually Paul, I guess the heavy drapes do a decent job from the midrange up and Bub's not worried about imaging anyway.

It would be a real boon if I could get the system to sit in my similar bay, but all my calculations suggest really irregular bass response

 

Absolutely, he'll get a much better picture I should imagine cos the electrons will get less jigglled about ... or something

 

It was humour Thomas,but clearly lost on you,

Oh drat, humour? I apologize, then.

 

well,clearly not that funny,so apologies needed from me it seems

 

I guess it would depend on the speakers. The ATCs like a bit of fresh air all around them, and there's not much bass from them in any case ;-)

 

Say hello to her from me.

'twas nice meeting you in Munich.

 

Ah, but what type of bass are we talking about here. I have discovered that there are two kinds. The controlled accurate kind that is present on the CD and the uncontrolled mushy boomy kind that isn't present on the CD. The former is highly desirable. The latter is not. I have recently discovered that the latter kind can be almost entirely removed (and most of the room interaction with it) by judicious application of a certain form of snake oil with a plug at one end and a socket at the other. This treatment then removes the need to have over-priced over-damped loudspeakers

 

Hi TB,

The ATC bass response is accurate: it was a Mana forum 'in-joke' (despite the fact that I'm out, and it isn't hugely funny) where almost everyone else uses Isobariks, poor things.

 

Ironic that Bub didn't have a bass problem until he was visited by the same magician recently reported casting spells over the tb system...

Paul

 

I was only poking fun with that last bit

Although I have to say that the subwoofer is now on the exit ramp and preparing to descend (once it's fixed that is )

 

Hi Paul,

The problem with hi-fi oneupmanship is that if you haven't heard the magician's system yourself, and I haven't (can't wait tho', hee hee) then you have to take their word for it that you have a 'bass-light' system. His background in 'ICE' plus his well-documented room-boom probably accounts for his taste for overblown bass.

 

Are you planning a visit to Cheltenham? Let me know if and when...

Paul

 

James,

Overblown bass, I must be using Briks then

 

38Hz

 

Let's not forget the room is the deciding factor here.

The likelihood is that the bay window in Bub's place is causing a wider phase cancellation than would be the case with a flat rear wall, although the resulting dip is likely to be less severe.

Tony's room does have substantial gain, meaning even bass limited speakers can produce surprising levels down to their cut off.

 

On my last visit to WM's, the bass boom was notable only for its absence. I remarked upon it at the time and demanded to know what acoustical wotsits had been deployed. But you all know the answer now - it's just a case of getting the amplifier to behave properly and get a grip on the speakers (well mostly it's that). And it's all down to the mains. Bizarre. Beam me up Scotty :beamup:

 

Steven, in fact the 'cut-off' is at 32 Hz anechoic, genuine 12" driver with 200W of bespoke class A behind it. The little Spendor SP 100s which you rave about cut-off at 45 Hz.

I have no worries whatsoever about the bass response. I think that popping speakers into a bay window area is a highly satisfactory idea. It gives you a view if nothing else.

 

Chris,

Sorry mate but even I consider that to be BS

WM had an issue with a fundemental room mode interacting with the port's tuning frequency, you do not get rid of boom by replacing a mains cable.

Sure you may reduce the overall level of bass in some way, but bass boom is associated with room generated temporal slur and bass doubling. WM might make some very good cables (I have yet to hear the latest), but unless his cables are removing bass from the original signal at certain frequencies (not good), they won't cure room associated problems.
