DIY computer speakers/sub

[Bull]

Hi i'm sick and tired of the complete crap speakers and sub systems you buy for computers.
The tiny satellites and the tiny driver size subwoofer you get in these packages give awful sound.
Having just spent £80 on a 2.1 pc sound system which sounds like crap,i'm very very annoyed.
The sub just rumbles at about 35hz and gives a horrible one note bass giving no deep bass or 80hz kick drum sounding bass.
And the Satellites are thin sounding lacking any midrange sounding muffled.

So I need advice on how to build a 2.1 system for pc but using diy parts.
I think maybe some 3 inch Tangband magnetic sheilded speakers,in small MDF cubes and a 6 inch or 8 inch sub in a ported box.Thats simple enough,but finding the amps to power the satellites and sub is much harder to find.
Unless I make the miniture amps and processors.
Also my limit is £100 to bulid a 2.1 system. Or I could build some high quality speakers like a Tang band 4 inch in a ported mini MDF cube,at least it would be easier than trying to look for a mini sized crossover and three mini sized amps.

If I built a 20cm x 20cm MDF cube to house a 4 inch fullrange Tangband speaker and add a small port and a small amp in each,or a seperate small amp outside the cabinet probably would be easier?.

yeah, Altec lansing I guess ! anyway, most of em do sound like crappy ±@£¢ these days...No mid-highs at all, ''impressive'' mid-bass and low RMS. I understand you !

Well, 2.1...If you chose to build a sub, youll need an amp for it or a 2VC driver... I suggest you to go for 2 quality sat. Have you heard of Silverflute or MCM? You'd get the bass you need and the mid highs you wish from almost any tweeters. I'm sure you can find an old receiver to drive them! Or you may build a little GC .

I have Monsoon MH-350s, planar-magnetic transducers up high....2.5" for mids and an active 4" ported to 50..Not impressive bass, but fairly accurate up high and great imaging. I WAS looking at a similar idea, but couldn't find an affordable amp-design...and I hadn't built a single amplifier to my name.

Now that I understand the electronics much better after having repaired a few remote controls and a car audio amp...I'm feeling ready to tackle a plug-in type amplifier. Will be interested in your amps....also, if you go active...you can go louder with less distortion also, you can add seperate EQ and such...hmmm...I'm drooling now

I've built the ELF 1.0 and 1.5 using the W3-871S and a sub with the Adire AV8. Something along those lines may work nicely.

Marchand Electronics makes an interesting amp for PC's.

You might look into some of the small Tripath amps.

I remember that they used to have a board similar to that Marchand board.

you will find what you desire there, dual 25 amp will be perfect

have any of guys heard of logitech's z680's?

definitely not your crappy set of comp speakers..

[Guss]

Yes I heard 3 set of logitech speakers, it sounds good! They don't tend to emphasis the ''bass'' that much, they have a better overall response with clear mids and less distortion...What annoyed me is that the model I own work with 2 AA batteries... I don't know where the cie is landed right now but they use to build good little computer spks unit.

I've heard good things about the Klipschies too.....obviously.

Few years ago Elektor magazine have one PC amplifier schematic which can be plugged in PCI slot.

Looks very similar as Marchand.
