Maybe that is it ... the average audiophile just does not know what they are missing and don't understand that if you have not acoustically treated your room, what you are missing is likely substantial.

Except 50% of those GIK posts are yours Erik :-)
Seriously though, I just looked at the last several hundred active discussions. 1 was definitely about discussions, 1 sort of, and I know they are mentioned any time subwoofers are brought up. In that period of time, tons of cable and similar discussions. Gik is frequently mentioned, but usually as a response to something else, perhaps not even asked, but acoustics rarely as a topic and never discussed in any depth.

I would also apply the GK factor, where the ultimately usefulness of a thread = 1/GK, where GK = the likelihood that geoffkait will post in a thread. This greatly skews the post count and ultimate usefulness of a thread, but anecdotally it is rare he posts in acoustics threads, which makes them far more useful, even if there are less of them :-)

This happens when people apply too much absorption.
While I agree that it’s very important, I some times wonder that without
specific measurements, that hap-hazard room treatments can sometimes do
more harm than good?

The way to deal with the "spouse" factor is to take them to a fabric store and let them pick the fabric (avoiding ones with "shiny" coverings). Rectangles are used because they are easy, but other shapes work too. We built some octagons because 45 degrees is an easy setting on the mitre saw.
That was before I saw millercarbon's recommendation about Corning. Which will be my first choice once I decide to proceed.

What did you do with the other geoffkait?

+1 gosta. The same trickery at audio trade shows. "Best of Show" ... is like an ugly dog contest.

That is totally untrue. Speakers shouldn't be musical, and I have never heard a speaker that would not be better with room treatments .. much much better. Some speakers need ideal conditions while some are so musical, room treatments don’t matter as much. See your statement above. Unless you are sitting nearfield, there can be more energy in reflections than directed.... guess what reflected energy does to timing? Why is the market so obsessed with speaker design which butchers the
time/phase domain? It's a common misconception that low damping factory, i.e. driver connected directly to the amplifier always results in lower distortion. Often it is worse. So when you combine the jacked up timing domain with
poor driver / amplifier control due to the crossovers... instruments
never sound real. |
Always appreciate the well thought out replies Duke! The comment I made below was mainly a response to a previous post that was made "railing" w.r.t. potential phase issues with speakers, while claiming some speakers are so good, that they don't need a treated room. The point I was trying to make, perhaps in too few words, is that "perfect" phase alignment of drivers in a speaker can be effectively ruined by reflections (of indeterminate frequency response and timing), especially in a "bad" room. Unless you are sitting nearfield, there can be more energy in
reflections than directed.... guess what reflected energy does to
timing? " |
Oh geoff, you are projecting again. The adults are trying to have a discussion about acoustics. Run along now.
|
Confucius say, "Man who talk all day about direction of cables, is compensating for his inadequate acoustics".

If I have the right data sheets, the GIK monster bass trips will be pretty useless for your two primary modes, which is usually the problem with bass traps. To work at the deepest modes they need to be huge.
Not good at guessing your nomenclature, so can you explain "SR LR".
|
dmaddox77, the two side walls "may" be best and this is often what is recommended, mainly based on math simulations done by Harmon and others. Problem, is, almost all (all) those simulations assume no output from the mains and and one of your primary modes (~50hz) will still have your mains putting out a lot unless you high pass filter them. This is where measurements really help.
Heavy carpet everywhere and more absorber panels may leave your room over damped. Would need to be careful. Need to balance diffusion. |
tvad, This is how my absorption panels are made. I always encourage people to do this. Big fabric stores always have really good deals on fabric, and when you are trying "match" your decor, what may not be popular, may work perfectly. We picked up 15 yards at about $4/yard that was a perfect compliment to our paint scheme. I constructed fabric covered acoustic panels many years ago using
fabrics my wife and I selected together that complement our living room
color palette. To our guests, the panels look like decorative accents.
Their purpose is disguised. |
