More thumping bass? You came to the right place. Don't worry, you're not alone - not everyone are using bassy PC speakers / headphones. This instructables will teach you to add more bass without destroying the rest of the sound.


/**Updated on 23 Jul 2016**/
- Major revision in each steps.

Before we get started, let me tell you that I have tested dozens of "free" software on the market and even some paid ones with the sole purpose of adding bass to my speakers. This method may not be the easiest, but definitely is the better sounding among others.

What is bass?
Bass is low-frequency sound we associate with thumping (boom boom). Bass frequencies start at 20-200Hz, while human ears perceive frequencies from 20-20,000Hz. That is approximately just 1% in number, but we can 'hear' and distinguish lower frequencies (bass) easily such that it is very common we demand good thumping bass.

How to add more bass?
Well, perhaps the easiest way to add bass is to do the opposite: keep the bass at 0 and the reduce the others. That seems easy but trust me, not alot of software especially free ones are capable of doing that properly. Once you completed this instructables, you will hear the difference. The only drawback is that this instructables only work with music files on your computer.

Disclaimer: This instructables comes with a low risk of damaging your audio equipment such as blown speaker or amp. Do not attempt to change settings that are explicitly prohibited!


What you need:

- PC with Windows OS

- foobar2000 [See attachment] or Click here for my portable version with some plugins added.

- foobar2000 plugins [VST Adapter, SH-1 EQ & Voxengo SPAN]

- Working built-in / external sound device

- PC speakers preferably with a subwoofer (or headphones)

- Access to Tone Generator for initial testing

Step 1: Initial Testing

Before we begin with adding more bass, first we have to ensure that there are no issues to your speakers or subwoofer. No I don't mean if they're faulty or not, but whether they are working properly.

1.) Check if your speaker or subwoofer are "rotten"

The problem with all speakers is that they are prone to foam degradation, especially when left in a long period of time. If you have a rotten speaker / sub, do not continue as this will not help them sound better. You have to re-foam the speaker by getting a repair kit or send it to a professional.

2.) Find where your subwoofer sounds best

There is a thing called sweet-spot for subwoofer. A subwoofer can sound better in certain place depending on the room, so it may be better to find a spot that will allow your subwoofer to sound much better before we continue.

You can place it under the table, facing the wall, behind a cupboard etc to find out where your subwoofer sounds best. I have a downfiring subwoofer (Megaworks 550) that sounds better if I tilt it 90-degree. So I put a thick rubber feet on the left side of the subwoofer where the port is located and it sounds better below my old desk.

3.) Bass knob: MAX is not best!

For PC Speakers, most bass knob only act as either attenuation knob or fixed equalizer knob. Maxing this knob doesn't help you get more optimal bass. Find out which position gives you the smoothest bass. And then foobar2000 will take it from there.

4.) Test your subwoofer

Use this Online Tone Generator to check your subwoofer frequency response. Set your volume at your normal listening level, and listen to your subwoofer. You can start listening from 100Hz to 30Hz and figure out where you would want to add some bass. Ideally most PC speakers struggles at 60Hz and below, but if your speaker is small it may already struggle at 100Hz.

Warning: If your subwoofer is smaller than 6.5" you can stop at 40-50Hz instead to prevent damage.

<p>YES! Klipsch is the first commercial manufacturer... They do sound sweet. I have the old Pro Media 5.1 with dual 8's and it's pretty sweet. However, the Polk 12 is mBA</p>
<p>They make really good speakers, too bad they pair it with short-lived amps. The iFi I mentioned above died on me few years ago. it was easily the best 2.1 computer speakers available 400$ can buy until today. </p>
<p>I have the Klipsch promedia 4.1's which were purchased around 1999 and still use them today. There are a few reasons they died on people prematurely. Once plugged in, the amp was always on (bad idea) So I drilled a small hole in the amp back-plate and connected a toggle switch to kill power when not in use.</p><p>Because they were always on, a few resistors and a diode would overheat a section of the pcb turning it black and it would ruin those components and possibly the circuit pathway. The trick was to remove those components, replace them w/ higher capacity components of the same value, and elevate them off or away from the board during replacement.</p><p>Then I tapped into the AC power feed, connected a step-down DC transformer (12 volt wall wort), and used a 12 cm computer fan to direct airflow to that region on the amp. </p><p>The promedia 5.1's suffered the same overheating design flaw and the fix is slightly more extensive but essentially the same. You can see the board turning black from overheating on the upper right side in the pic. </p>
<p>yeah, it's a pity those great PC speakers didn't make it. they don't make them like they used to. my cambridge soundworks 550 also died by itself when I arrived home from a month vacation. </p><p>i have opened the iFi and even send it to a few technician to no avail. i even replaced all the caps and found out the amps are TDA8924 and TDA8920. there are no burnt components at all. well they're digital so without a manual i am completely clueless. </p><p>finally decided to save and go for proper receiver with bookshelf setup. there are days i would miss having simple good-sounding 2.1 like the iFi where I can just plug an iPod and use the RF remote to play some music. but those days are just gone.</p><p>i am happy for the fact that your promedia 4.1 is still kicking ass! a friend bought my altec lansing ada885 which was once a cheaper alternative to the promedia 4.1 back in 2000 and he is still using it today.</p>
<p>There is a guy who advertises on fleabay named Stpeteshepherd who offers his services for the old Klipsch 4.1 &amp; 5.1 systems. Some people won't easily give up on those systems because they sound phenomenal. Klipsch refused to disclose a schematic for those Bash amps so he mapped out them out himself. I did my own repair but he pointed me in the right direction. I also have a set of the Z-5500's and they're louder but the sound isn't quite as nice as the Klipsch.</p>
<p>Thanks it worked like a charm on my Cambridge CSW130 but I have a question and that's how do you decrease the amount of clipping?</p>
<p>You will have to reduce the input volume in the SH-1 Equalizer (knob on the left bottom corner) so you will have to turn up the main volume in the end. If it still clips, try to reduce the bass knob, small subwoofer distorts easily.</p>
KLIPSCH.....one of the greatest speaker that i've ever heard..lol...
i cant figure out how to get to step 1
hi, in foobar2000, navigate to &quot;View&quot; on top of the window, click it and select &quot;Equalizer&quot;. <br><br>Once the equalizer is ticked (enabled), you can increase and 55hz bar to get more bass, but remember to click auto-level each time you increase it.<br><br>hope this helps, good luck!
haha sweet<br /> I was reading and&nbsp;I see papertube mod on Edifier MP300? :P<br /> was happy to hear you still remember this mod :D
lol. of course i should. it's one great trick i found few years back. anyone using Edifier MP300 / MP300+ should use it. <br />
Why do you consider SRS&nbsp;Audio Sandbox and Dolby Prologic&nbsp;IIx to be &quot;creepy&quot;?<br />
SRS makes the sound quality very fake.<br /> trebles sounded like plastic bag lol<br /> and sometimes there's too much trebles and you can't reduce it :(<br /> <br /> that dolby thing...I dunno lol
The SRS, i found both the Sandbox and TruSurround that comes with my logitech z cinema are overrated. using couple of freeware such as foobar2000 above it makes things sounds better. the only SRS I used is the windows mobile version.<br /> <br /> and for the DPLIIx, my laptop has it embedded. Doesn't sound good at all, perhaps they just reverse the matrix of front speakers for the rear channels. However, I turn them on so they upmix things from internet like youtube.<br />
0_0 It has a spectrogram!? SO&nbsp;COOL!! I can see phasing!<br /> <br /> Is there any way to wire this so that it displays the spectrogram of a real-time line in or microphone? Or do you know of any other freeware real-time spectrum analyzers? I don't have a good way to visually monitor things in high detail when I'm mastering in Reason (the vocoder trick works, but it's not a large display).<br />
Regarding the spectrogram, i'm not really certain. However, you could check at the official forums at <a href="http://www.hydrogenaudio.org/forums/" rel="nofollow">www.hydrogenaudio.org/forums/</a><br /> <br /> Compared to WMP, of course foobar2000's EQ&nbsp;sounds much better. I have not touch WMP for music playback since i use foobar2000. lol<br /> <br /> thanks and enjoy...<br /> <br /> <br />
Yeah, I&nbsp;just found a bunch of stuff. This website has lots of downloads and you can filter by freeware etc: http://www.hitsquad.com/smm/<br />
Thank you!!!!! This is wonderful! Two things were really starting to piss me off about WMP:<br /> 1) Single-band compression causing ducking of my low-end when the high end peaked, giving that obnoxious &quot;wobbly&quot; sound. (I'm a big audiophile)<br /> 2) It seems like it's been taking longer and longer to start up. <br /> <br /> I use VLC, primarily for FLAC and streaming, but I&nbsp;don't like it's UI and lack of library support. I&nbsp;am giving foobar a shot and it looks like it's going to be a good match :)<br />
