True or False?

Don’t get me started on room correction. What a nightmare. Get a test CD (Stereophile for example), and a sound measuring device. Run the test in your room at listening position. Look at the frequency response. Gaps, holes, peaks? now what is causing it and what does it take to fix it?
not fun.

It is all relative to the road taken...i had the fun of my life with room correction...

I used a mechanical equalizer (32 tubes and recycled plumber pipes with straws for neck all variable and different for volume/lenght/ diameter ratio) which will become part of my audio room...Not an electronical equalizer with a mic.

I used the timbre of voice or instrument instead of a set of limited tested frequencies response and my Ears for the feed back instead of a mic...

Results: the 2 listening position which are good are large enough and not a very narrow one in millimeter out of which no measure means nothing...
I control all aspect of acoustic at will: imaging, timbre perception, soundstage, listener envelopment ,source width...

Is it perfect? no

Is it good? so good that i "trash" all my headphones (7 pairs) and my average speakers work at their best.... Because like Helmholtz i modified the room response and tuned it to the speakers or instrument which was playing...Not the opposite modifying the speakers or the instrument for the room...

You can chose for sure to modify ALSO the speakers response to some set of frequencies but it is good for a last fine tuning, that will NEVER replace room passive material treatment at all, and that will NEVER replace my activation of the pressure zones of the room by mechanical means...Passive materials treatment in small room must be done using in a positive way the timing treshold and reverberations of the small room... The mechanical equalizer is used to mark out or to " buoy" the waves of EACH speaker differently FOR EACH ear, making the brain easily able to recreate 3-d directions and image in the room....

It is was fun and rewarding ....It takes me a month.....It is like tuning a piano...

The room geometry and content is like the piano particular form and the pressure zones are like string tightly vibrating or resonant.... At the speed of sound, waves may cross a small room many times before the brain analyse them in some 80 milliseconds....Then acoustic of room is not only a set of passive wall enclosures waiting for the sound to bounce politely on them it is a complex distribution set of pressure engines...

I dont need a Smyth realizer headphone anymore...

cost: peanuts

Inconvenient: impossible to put this unesthetical devices in a living room...







The only luxury in audio is not costly gear it is a dedicated room....

A straw can kill a room or transform it completely...

Embed everything before upgrading anything...

Discussions about cables & interconnects and, for that matter, just about all things audiophilia always have a propensity for generating strong opinions, especially when it comes to speaker cables & interconnects. After all of the proselytizing, hogwash and mean spirited satire from some "experts", however, it always comes down to the same thing. All one can do is a bit of due diligence with respect to researching products of interest in an attempt to become as informed and knowledgeable as possible and, then, go out and do the most important research of all (i.e. critical listening). If those $5,000 speaker cables sound better to YOU than the $300 cables and YOU think they are worth the extra $4,700, buy ’em.
