get a x-fi soundcard. there will be bass boost up to +10dB from 10hz i think. there is also SRS Audio Sandbox but i find it to be trash, no match to foobar's supereq.

yeah in the x-fi control panel there is bass boost option. but in the latest driver there is filter which will prevent clipping and also give those filter sound effect like ReplayGain. terrible.

i never tried SRS Premium, only tried SRS Audio Sandbox and SRS TruSurround HD (that comes with Logitech Z Cinema). i prefer foobar2000 than them because when i turn SRS Audio Sandbox on, even with everything in 0 there is some changes in dynamics. and when you push the bass to the max the filter sound comes again, or sometimes clipping. bringing down foobar2000 supereqs is my current favorite so far, if you
like bass you should try it sometime.

well for me just keep the 55hz at 0 and let everything below it, say -9. that way nothing is boosted, so no clipping. but then need to increase the speaker volume. yeah using earphones can hear to 10hz, but at 30hz, my speakers compared to in-ear, still prefer speakers. anything below that none of my speakers can do lol

well that one is your speaker limit... you must know what's your subwoofer frequency limit. i suggest you try to move to better location for deep bass. and for sub as big as S730, make sure your room is not small.

yeah then i think it's the limit of S730. have you tried using frequency generator to check which frequency it drops the most?

around 30-40hz is okay. dont expect computer speakers to go down to 20hz.

i think expecting S730 to go 20hz is asking alot. seriously. let's take an example of the famous Creative S750 (triple voice-coil sub) and Klipsch Promedia Ultra 5.1 (dual active sub). Both of them only goes to around 27hz and that's it. the cheaper Creative G500 can go near to 30hz with the help of specially tuned twin ports, but the distortion values are also higher on that range.

Techlabs did testing on both S730 and G500. whether the tests are accurate or not it is subjective, but you can see yourself that S730 starts quitting near 50hz. that's pretty high. also, if your subwoofer cone moves at 10hz, it doesn't mean it is properly producing 10hz. no PC speakers at the moment are capable of doing so.



-edit added z2300

i think that's gonna be difficult since S730 is using passive radiator which i believe is tuned much higher than the port that Z2300 uses. added graph of Z2300 above. if you want the S730 to sounds much lower, you have to replace the passive radiator with the one that is tuned much lower.

at 20-40hz both system already lose more than 10dB, so it's more or less the same. but since Techlabs did not provide us with S730 and Z2300 bass settings, the graph only tells us "estimation" of the subwoofer performance. hence in the real-life the result will vary.

also i noticed that both of them are playing at different level of loudness, one is at 60dB another is at 85dB

Logitech Z2300 have been replaced with Z623.

may have been abused. i tried listen in one shop it was horrible, very dry.

sealed with passive radiator.

1 active driver, 2 passive radiator at sides opposing each other to be in phase with each other if not wrong. quite good, but i prefer klipsch gmx for 6.5" sub.

creative always ex one. but if promo the price is very cheap. this last 2-3 weeks the price of Creative T3 in Singapore only $200 (RM480) due to the IT Show and Creative Warehouse sale. usual price is $280 (RM670) - $300 (RM720)

3 drivers. but only 1 active, the 2 are just dummies, following the active one.

lol why class D amp ex? i always thought the other type amp is ex.

thanks for the insight. now i know that most of the multimedia speakers uses class A/B and some uses class D.

can check your speakers spec or the op-amp spec. some speakers they mention it in the specification, what type of op-amp it is using. most common used is the class AB.

based on what i've been reading, the class D amps cost less the manufacture, but usually more on research and design. also, class D, since in favor of power efficiency, usually ideal for subwoofer application.

most probably class AB.

X-Fi Crystallizer


basically just boost up the low and high leaving the mids behind. was never a fan of CMSS or Crystallizer. the bass boost is not bad though, although it starts to distort or normalized above +8dB. but still, C3 will definitely profit from the bass boost.

XtremeMusic uses PCI while Titanium uses PCIe. rest of the spec seems to be more or less identical, with Titanium have DDL out-of-the-box, and more X-RAM which is pretty much useless these days.

edit: different chip as well. XtremeMusic using CA20K1 while Titanium uses CA20K2. but i wouldn't worry about that if i were you.

there are 2 types of signal, analog and digital. just assume that digital is 'raw' one and analog is the 'ready to use'. most PC / multimedia speakers are using analog connection, just like earphone / headphone.

soundcard / dac or whatever it is, convert the digital (raw) to analog (ready to eat) so the speaker is ready to produce the sound. there is also speakers with digital input (i.e. Edifier S730) so it can accept both analog and digital data. if it is given analog, it will produce sound immediately, if it is given digital, the built in decoder will convert (cook) the digital data into analog data.

controversies will arise when people ask, which one is better. there is no right or wrong answer, everything depends on your taste. what power911 is saying is that, use the one which u have the best. if you have a good soundcard, let it (cook) for you, if you have a lousy soundcard, let the built-in converter (cook) for you.

as to the difference between those X-Fi, X-Fi Titanium uses CA20K2 chip, XtremeMusic uses CA20K1. not sure how different these 2 are but i doubt they differ much. X-RAM, no need to care about it as it's only used in older Battlefield games. DDL is Dolby Digital Live, Titanium have it ready, for XtremeMusic must unlock it first then can use.

you must try before knowing which one better than the other. there are 2 options now, going digital (with optical cable or coaxial cable) or normal analog. then check the sound difference.

but one thing for sure, turn off all CMSS and Crystallizer and EAX effects. if you want more bass can try the bass boost, but if you add too much it will distort or clip or compressed.
