Hmm...I thought logitech speakers has good on low frequency bass but this Z5500 doesn't seems like.

box tuned to 40Hz?
means how?
I thought can only tune to one frequency?

yup... one frequency only.
that means logitech designed it to play best on 40hz... but the amp is not giving the box a chance...

there's ppl in the internet connecting the sub with a different amp and they say it's awesome

so anyone know how to 'get rid' of this filter?

in my z cinema they like limit anything below 30hz so it doesn't move. while for the edifier, klipsch and altec lansing i can still see they're clearly moving. heck, even my laptop subwoofer moves when i supply 30hz tones.

for z cinema i don't know what freq they tune, but for sure at 40hz it's just normal. much more boomy at 70-80hz range.

You need to check the circuit and the woofer crossover there....

hmmnn something not right about what you said haha
its supposed to means loji plays lower frequency bass
and the other plays all thats sounds like bass?

i don't know which is right, my friend who works at bose told me about subs....
wouldn't it be messy fengtau sounding? subs are supoosed to play low frequencies only and stay invisible... 'only can feel the bass'

now ima confused

i've seen tons of polard caps in cheepos

I had that too.
But it really depends,sometimes..
Haha,wat worked for Bose might not work for Logi..
Unless bring the test tone to go and try only.

woofer n subwoofer is different bro...
in computer speaker there's no subwoofers... all woofers only
all make sound and not feel

subwoofer... no hope lol... too expensive...
if got chance,u try rotary subwoofer... no speakers used all kipas only.
subwoofers are meant to shake your body and not make sound
normally 5-30hz is called sub-bass frequency.
humans can't hear it tho...
that's why it's called 'sub'... aka woofer sampingan (add ons )

sheesh, now i need to go relearn all my audiophiles >_<

I always thought that Logitech plays nice on low frequency bass but then on the video, the Z5500 woofer can react with such low frequency but theres filter on circuit limits the frequency amplitude or cut off so that it can't react at those frequencies. The volume are quite loud, Edifier one response the frequency as it should, but the Logitech goes something wrong.

Normally people wanted 2.1 speaker woofer to sound like come from anywhere but reality it can be heard at a direction so it needs to be positioned.

You can have fun with the subwoofer by playing a 5hz tone and see how funny it react, but remember that don't play too long it can be quite stress.

logitech plays them low... yea
but logitech can't play lower than low

edifier... on the other hand,plays pretty high...
but they can go very low too

I see advantages on edifier XD

easiest song to test would be the infamous bass i love you. there will be this low note where the subwoofer will slam obviously. now during that time, my z cinema (and z2300 and z5500 in youtube videos) will not slam as it suppose to be. already confirm with my klipsch ifi, altec ada885, edifier r501 and many other speakers w/o filter.

if only i can find sth inside my z cinema that would disable this filter. btw haven't opened it yet, only a pic from internet.

The bass is too low that unable to listen already, just watching the subwoofer moving. Most of the multimedia speaker does not have crossover, it just let the woofer response to the range it can response.

btw, that circuit quite complex

well of course not until that low, but at least if the z cinema can output until 27 or 30hz before it's totally unhearable. only when placed in sweet spot the ADA885 can hear at 27hz before starting to get softer and softer. iFi is at 30hz. z cinema is 35hz, everything below is not softer, but blocked instead. that's why after getting used listen to these 2 listening to z cinema got obvious missing tone.

yes quite complex, but it also include the "DAC" since the usb port is at the back of the board.

poor logitech, not a good thing...by cutting off anything below 35hz, it will lose out the dynamic bass.

Edifier wins...keep it up~

I like Edifier higher end speaker the satellite coz enclosed in a heavy box, having baffle on the speakers and silk dome tweeter

not to mention... it feels solid,tight and heavy, making me think money well worth spent on wood instead of air

edifier s730
