Hi,
I want to build a pair of speakers to use with my PC. I have the Sonic Impact T-amp to power the system and I was looking into using a fullrange driver as they seem to be the most efficient. The fostex range are the ones I'm most interested in (6.5" or 8").
Now my problem is I need the speaker cabinets to be compact enough to use on my desktop but I also want good quality sound with at least decent bass response (55hz). After reading a load of threads I'm beginning to realise this might be too much to ask as all I see is mention of horn loaded speakers and transmission lines.
So what I want to know is how realistic is it to get a good sound (ie. decent bass extension, good mids and treble) from a fostex fe127e or fe207e in a small-ish cabinet? And what would be the best small cabinet type to use (BR/TL/something totally unique etc)?
Any advice is most appreciated.
Thanks

You would be surprised. Something you need to factor in is how close your listening distance is - in fact I wouldn't be at all surprised if you could acceptably use even lower eff. speakers than the Jordan and still have acceptable SPL's. Note you'll also need a bucking magnet or a shielded magnet driver for computer use.

Actually- you're completely right. This whole conversation was about size and I knew it.. I feel like such a dunce!
If I could add sound quality to the equation, I would like to suggest that it's possible to build a fairly sensitive box that's small and plays low- but with horrible sound quality. Think of those "one note wonders" you hear driving down the road. That's what I'm talking about- but thanks for correcting me, I should have said size !
I´ve heard the Fostex FE-167 recommended enclosure (15liter) makes a nice near- midfield-monitor.
That of course needs quite a big desk...
I´m gonna test that driver in 15liter very soon and can let you know if you´re interested.
You could also have a look at the little T-line someone built with the Fe-107 (locust).
Listening in the nearfield changes power requirements quite heavily so...

How small is "small" ?
Keeping the fs of such a driver in mind, it can be hard to achieve 55 Hz. With a total volume of 7 lt, 40 cm TL length, 49 cm sq. cross-section area, placing port at the back, light damping and 4.5 lt of rear chamber, it may be possible to reach 65 Hz with a Fostex FE103E. It can give an idea of the low frequencies, but just the idea. They love to be placed at the corners on my desk, but at work, I don't have that luxary, so a little EQ help can give a similar result in return of some fidelity.

Hi,
Maybe this is a little over the top for a computer system, but I like the idea and I'm a bit tempted to have a go myself if I get the time one day. How about using horns, but integrate a pair into a desk joining the two speaker cabinets, like the picture? and just sit the bottom of the cabs on the floor to support the desk and monitor etc.
