Bass Tilt, Treble Tilt and how its useful

Dear sonic master,
The function you illustrate cannot compensate for room related problems,it can only work on soffit mounted monitors where the back wall is negated and the speaker driver sees an infinte baffle with no diffraction issues and quater wave cancellations. Even the most sophisticated digital room correction systems are limited in their abilities(for freestading speakers) below 200Hz, and above 700Hz corrections are meaningless in more than one position.Tilt control features are available in passive systems too,but in the preamp section.The Quad preamplifiers feature tilt functions in their design.Tilt controls can only compensate for recording problems.
The most elegant way to remove the room from the equation is to have a speaker with a cardiod pattern in the frequencies above 150Hz and a pressure-gardient pattern below it.This sort of speaker(active or passive ) will act in a friendly way with most rooms.However the sweet spot is limited in size and the tonal balance usually is not to everyones' taste.
Regards Deaf.

Could you please elucidate, in slightly layman terms

for CDP sources, would prefer an equilisers in the digital domain (Like behringer) than in the analogue domain as in tine controls.
appears more cleaner to me !

Double edged sword my friend.

Dear Krish
It means it has a cardiod radiation pattern above 150 cycles and a figure of 8 radiation pattern below 150 cycles.

Agree with Deaf. The implication on tonal quality is inevitable. I would invest that money in simple room treatments..

Arj, i would think it would be even worse to do room-correction in digital domain (given the limitations of sampling)...

well siva.. but im not talking about in the digital domain...I am talkin about in the active crossover section.. I dont think there would be any tonal quality deformation would occur with such modifications...

cheers,

Dear Sonic Master
I think the answer to that one is my first post on this thread.Tilting driver response does not solve issues,lets say a 6-10db suckout at 100Hz and a 4db boost at 50Hz.This a real world problem that exists in most rooms.How do you resolve this.Just going active does nothing for this problem.Any sort of EQ will screw up things even more.I gave a suggestion on the ideal speaker polar pattern,all of you should look at the idea more carefully.
Regards Deaf.

Personally I am not in favour of putting anything in the purity of sound.. so I am not too hot on this either. But this
was the suggestion given by a TAS reviewer (pretty well known) for ideal room response. of course he uses the much more expensive TACT2.2 appreantly there are some "Bumps" which can never be changed by room treatment due to the inherent dimensions of the room.

As as long as your speaker is well designed, the only way to make the response as flat a possible (Without making it sound bad)is via digital EQ. this can be made Not to affect the sound by making the sampling rate many times higher than the standard 44.1, making the correction and then downsampling back to 44.1 to feed the DAC.
Aparently it works, but have never heard one so cannot really comment more !
