Which speakers should I buy?

[puntoMX]

I would go with the Logitech speakers too. I don’t care what a review says but I compared some speakers my self. The Harman Kardon are pure design and you pay for that.

If you want something better buy an amp and some speakers (stereo, just 2) with each 16-20cm woofer/midrange and a 2.5cm dome tweeter. Go to the store to listen to them to pick them before you buy them, take your own music with you and take your time. No review can tell you what you ears will do .

What kind of amp and speakers to make one. Very interested,

I was talking about a stereo amp from the store from Pioneer or Kenwood or so, just the lowest model with brand X speakers, 2 way, good enough for most of us. Subwoofer systems are nice when you look for small compact solutions but aren’t that good for music.

There are do-it-yourself amp kits that are cheap and not so bad, based on MOSfets witch are efficient and powerful and sound good in general. Make sure you by a good transformer and use big caps to get a good constant current to the MOSfet transistors. That’s just basically it, lots of info all over the internet. Don’t get hooked to it .

For the speakers; Buy speakers (drivers) from VIFA: Scandinavian and from the same group as ScanSpeak (best you can buy for money) and SEAS. Kit’s with filters and drawings are sold too from this brand. Only thing you have to build the boxes from MDF and connect all the components.

PM me if you want to build your own speaker system, I can help you to start .

The result of this is that bump sound when you turn off your computer.

That's the result of improper grounding, usually from an on-board sound card. A good quality sound card should not do that.

Nothing to do with grounding. It’s just a charge/de-charge at the line out witch is normal. A good amp should have protection for this. Just a failure in the design that it doesn’t have that protection nor a switch.
