here is the thread, really long one...: HOWTO: PulseAudio Fixes & System-Wide Equalizer Support - Ubuntu Forums
audacious, that i think is a fork of xmms comes with a 31band eq plugin Audacious - Plugins
when i was a gentoo user i used songbird, but then i switched to mac, and at the time, i didn't care for sound quality... there is a thread 'linux the way to go' in this forum too...
perhaps linux has the best mediacenter projects going on, many interest around them for it involves ip-tv business and embedded devices, also intel is giving funds to some projects, so maybe we will see something big soon or later. probabily linux with one of its mediacenters is the best way if a dedicated machine, also fanless like an eeeBox pc can be dedicated to the task.
i see there exist a room equalizer designed for recording studios called ARC (vst) but it retails for around 500$! so i'm not going to try 🙂 i think that from a theoretical point of view take the room into account in the frequency domain should not be mystic science, as interest in pc audio grows we will certainly see it made affordable.

Hi Badman and Rjbond3rd, I agree as well about room modes. They have to be taken care of with speaker positioning and/or room treatment. I´ll try to use RoomEQWizard as it seems to be a useful tool.

i tought this link can be useful too:
Equal loudness contours and audiometry - Test your own hearing
originally intended to auto measure loudness contour it's quick way to have test tones with decibel differences...
i moved the alpairs OB, with a dsp high-pass and 10db boost at 100hz, it's funny that the little driver can make some music on it's own on the 70cm baffle 🙂 hidden in osx there are several usefull dsp, i really suggest you osx guys install a jack software
here is also the original implementation of jack software for linux (and windows)
JACK | connecting a world of audio
although i have not tried it and don't know what kind of plugins run under linux, maybe vst?

I'm sorry this might be a silly question, but do you happen to mean that it's possible to damage the drivers by boosting the lower frequencies too much?
yes, jack itself is a server for routing audio signals beetween softwares almost like you would with hardware components and cables. it's low latency and very effective.
magnade, very interesting. you should make your achivements public...
@ChrisB, Dave: have you tried the apple audiounit equalizer? i'm very curious what you guys with a lot of experience think of the sound quality... also the commercial dsp i suggested i think deserves a try...
@Bob: can you tell us more about your equalizations curves? i don't have such a good ear it would be very good to learn seeing the kind of curves you make.

I'll be sending a patch back to the guy that wrote the original 15 band eq
perhaps he will post it with all this plugins as I don't want to get into starting
a project or really maintaining it (not that there is much to maintain)

great! thanks for sharing then 🙂
this can be of interest for the Squeeze owners:

it's take from a thread in the pc-based section of this forum

Do I need to worry about damaging my FE-126E drivers if I raise the bass frequencies too high in Foobar's built-in EQ?
I'm looking for an answer as I'm now concerned that I could be doing permanent harm to them by "pumping up the bass" too much.
Cheers guys.

in my mind YES, you'll exced xmax quicker... but there is a japanese guy equalizing a pair of alpair5 in sealed boxes 20hz flat for near field computer monitors...
it would be interesting to know Bob's experience, since lowther have so little xmax...
btw given a hi-sensitivity speaker you can reverse eq, shelfing any thing above what you want to bring up, like it's done to balance a line array, but my results have been quite poor by now.

I had gathered everything to try some experiments including HiJack... and then Duo tossed me some really strongmagnets, i fumbled and they landed on my laptop right where the HD was... then i had to get a new harddrive, and i haven't had a chance to pursue again.
dave
oh really? i'm sorry..
if physical damage was done to the hardrive and you had critical data on it you can try retriving data in a specialized laboratory, they have special hardware readers for hd plates, i hope nothing important went lost.

Any idea how I can figure how how much room I have to EQ up the lower frequencies on my FE-126E's before risking damaging the drivers?
Thanks guys.
Thanks guys.
Common sense.You just can't ask a loudspeaker to exceed its limits .
Just play various tones at various levels and see (and hear) when excessive cone excursion brings a worsening to the total spectrum of frequencies.
Human.bin , I installed the program you suggested , on my mac , and it works!
Though I really dislike DSP , it gives life to cheap 2.1 sets. Ciao

Bosk, it really depends on the material played. you can also think of adding a low-shelf filter prior to eq, so to protect furthermore the drivers (wavelength doubles every octave, so i do think does xone exscursion if not more)
I do so: read the T/S of your drivers, the xmax tells you how far it can travel under control (often it is one way, so the double), then play a track with good bass presence and look at the driver, if it flips over xmax readjust the eq, until you find a compromise between balance and volume level.
if you are exagerating you will also hear it clip severely and then mechanical noises, but anyway don't fear to broken it at the first time you experiment for xmax indicates drivers exscursion under control, but really it can travel more before physical damage (xlim parameter). also this parameters vary a lot in the lower range due to cabinet damping, which shifts driver fs i think (or otherwise OB flipping resonance or something like this)
that's all i know and do when i experiment, i'm also 100% sure it's not nearly 100% correct, not 100% complete: so be wise and keep in mind the value of the drivers you experiment with.
let us know your results

That can certainly be a great way to throw away more raw sensitivity than the difference between driver with different operating parameters. If accomplished at line level, you're not "wasting" watts in the traditional sense of passive XO/filter attenuation, but you can still be hamstringing yourself in terms of effective output levels.
"Compensating" for, or even designing that into to the system, such as with line arrays, can generate a different set of issues.
hijack gives possibilities to make quick comparison test bypassing elements:
i was trying making the same amount of bsc out of both the buil-in audiounit equalizer and the commercial 64bit and to me the aunit ruins the sound, sort of sucking life while the apulSoft apEq sounds really fine to me
