@power911 or if you want easy get a speaker with 12V DC input, can probably directly put into the cigarette lighter...

bandpass is the subwoofer construction. there are sealed, reflex, bandpass, horn etc for subwoofer. common one are reflex, that is with port to enhance the tuned frequency. the most important part is how the subwoofer itself is engineered. one properly engineered subwoofer will be better than poorly engineered one.

for filter below 20hz it's usually called subsonic (infrasound) filter. for the below 200hz it's called crossover. THX recommend HT subs to be crossovered at 80hz but for PC speakers that's difficult because very few PC speakers satellites make it to 80hz properly. that's why they are classified as PC speakers...

yeah exactly each construction has its pros and cons. but that can be overcome by good engineering and tuning. usually people will say ported sub will have port flutter when playing in medium to high volume. but i believe that only happens if you underport / overport your subs. properly tuned sub will have no flutter sound in any volume.

bandpass im not so sure, only read about it has great efficiency but low performance at lower frequencies (deeper bass), but as i don't even have any decent bandpass PC speakers im not sure.

I never use any PC speakers with passive radiator / horn / sealed so not sure about that. again, it's matter of tuning i believe. so it's not fair to judge a sub performance by its construction, power, brand or dimension, especially looks.

@viruz019

mod your C3 by replacing your subwoofer with 4-ohm 8inch (maybe 50W) subwoofer driver. surely bring more bass

how about go to jalan pasar and find some 8" 4ohm sub... probably doesnt cost much...

most PC speakers already have built-in amp so it pumps out power to your speakers. that's why you plug your active PC speakers to wall electricity outlet. if you add another amp, it will overheat the PC speakers built in amp as it try to process amplified signal even further. in long term probably will damage or burn the built-in amp.

wow cosef, many mods on your M3300 already... btw mine the sub magnetic shield is gold color, not silver.

i recently remove subwoofer from my 'modded' M3300 and transfer it to old Creative Inspire 2400 (5.25" sub 4ohm) since it has blown sub voicecoil. the bad thing is that M3300 is 6.5" and 8ohm so first i have to saw the box and the power is minimized. good thing there is no more muddy bass like when it was paired with M3300 amp.

I guess now I no longer have any M3300 left... sub goes to other speakers, sats goes to other speakers. anyone want M3300 amp?

yea of course free, but since im not from msia it's also kinda pointless

usually there is an option for "ReplayGain" in foobar2000. but I do not recommend it. some ppl also doesn't like replaygain..

haha and i am nowhere near expert in foobar2000... just quite happy using its equalizer... actually i wanted to try other EQ with VST plugin but well, i am quite busy repairing my 2.1 speaker first...

I suggest you skip to S730 if you want better overall sound than C3. then next time, you can add soundcard to boost the performance... the only drawback is the super heavy and big 10" subwoofer. if you have small room then it wouldn't be at its max potential.

well it depends on you too, for me i basically hate it if the room is too small makes the sound very boomy. upgrading the subwoofer doesn't really help because it's the room characteristic to begin with. that's why if your room is small you might consider before upgrade. of course the S730 satellites are far better than C3.

its detachable by removing screw underneath the bottom rubber feet. but take note since the subwoofer is downfiring you still have to substitute the feet otherwise it will be like floating.

you need to replace the subwoofer. try 8inch with 4ohm driver. 50W should be ok. or replace the whole subwoofer and box entirely.

replacing the amp is also possible but that's just same as replacing the whole system.

actually, going to 20hz is pretty much impossible for PC speakers. especially with only 8". even the S730 is nowhere near 20hz. but if tuned correctly at least the DA5kpro can reach 40 - 35hz with ease.

i think IEM can produce 20hz, but at low volume. hence not so much oomhh compared to huge subwoofers...


not sure about that... but what im sure is that it also depends on your room. if your room is small (thus the bass echoes) it may not produce 30hz pretty well, let alone 20hz... i heard my speakers did 30hz before, but not in my bedroom, so it's also pointless... two of them are THX certified, though i don't really care about it either, it's just a logo that makes my friends ask: hey, your speakers got THX?

Edifier MP300 / MP300 Plus Rechargeable Lithium Battery MOD

Now this has been my dream since I first bought one white Edifier MP300 back in 2007. Back then, I tried connecting 8x regular AA batteries to produce 12V for the MP300. It works, but the battery died too quickly and the sound isn't loud at all (underpowered). Not long, I gave my Edifier MP300 to my ex-gf so I don't have anything to mod.

Last month, I ordered one Lithium Battery (12V, 3800mah) to power up my old Creative Inspire 2400. It works, but after I found out that the power supply capacitor (1x 4700uF 25V) leaked and I replaced it with bigger one (1x 6800uF 35V). The lithium battery no longer works, it seems like the battery could not send much current.

Cut the story short, I borrowed a relative's Edifier MP300 Plus. It uses identical transformer as the MP300 (12V 1.3A SMPS). I quickly plugged my lithium battery to test. VOILA! The MP300 works immediately without any problem such as hissing or low volume. It works perfectly.

So, those of you who loves MP300 and want it to be battery-powered, you can get a 12V lithium battery from ebay (it cost about 10-20USD depending on capacity) and hook it to your MP300. Don't forget the papertube mod if you feel the bass is a bit muddy. After all it's a 2" subwoofer inside that aluminium tube.

EDIT: Video blocked by YouTube, I will record using other song soon.

yeah, it's been my dream to be able to listen to portable 2.1 system, at least in a bathroom.

too bad i don't have any MP300 right now... beside, I haven't figured out how long the battery can last... but for the previous Inspire 2400 (which takes 12V 2A) it works more than an hour from full-charge at full volume. My estimation would be the battery could last up to 2 hours on a MP300.

yes, the lithium battery is rechargeable. of course, otherwise it'd be a waste... lol btw the original MP300 only has 4x 470uF 25V solid capacitor inside the board, so it probably use way less power than my Inspire 2400.

anyone here try putting foam inside their satellites or their subwoofer? i know some Edifier speakers are shipped with foam in their sub and sats, but just wondering anyone here did it...

I just tried adding foam to my AL speakers (I know, AL forum is dead) i feel there is noticeable improvement in bottom mid to vocal area. not sure if placebo, so i will listen for few days first... the foam i used is polyethylene foam, looks like this:

i never see the magic foam before... is it like the memory foam found in pillows? or like the yellow scotch-brite knockoff? if the first one then no wonder expensive liao.. currently my ikea mattress is that kind of material (ikea sultan fonnes).

below is the image of the ADA885 front sat. same goes for the rear one. no crossover, thin cables and thin plastic housing. so i tried putting small PE foam and it actually sound better for now... wanted to put a thicker one but no space. i think im gonna try this on my megaworks since the creative only got normal cheap foam and it rings when playing at moderate to high volume...
