Initial Experiments for Fun

stuphi · 8th May 2009, 10:30 PM

Hi,

I have bought a box of speaker drivers from some guy on ebay. I intend to build a number of speakers with them for fun, and to learn a bit about how different speakers sound.

Initially I have built some sealed units, but over the next few weeks and months, will try my hand at some alternative configurations. It is my intention to document them on my website here.

Any suggestions?

Regards,
Philip.

Hello Philip,

Suggestions? Yes give us the driver specs here in the thread. Much easier.

Oh, and welcome to the forums.

Now that is a cool thing to do.

BIB's are pretty interesting to build. Have you come across them before?

Another recommendation, or rather something I want to try myself, is to build a calibration mic, there's lots of pages on that, here's one: http://www.speakerbuilder.net/web_fi...diymicmain.htm

The specs of the drivers I am using are as follows

Vas = 1.62
Qts = 0.52
Qes = 0.63
Fs = 89.98 Hz
Dia = 80 mm

That is all I know. I have 16 of them, so the idea is to build a range of small speakers. Possibly including using multiple drivers in some form of small sub.

I don't expect full HiFi quality, but to compare what the difference is between different enclosures.

Finally, I would like to build a set of speakers with with some decent drivers for my main system. Again, I don't intend to be too critical. They will just need to sound good to my ear, and hopefully impress my visitors.

Regards,
Philip

Post a pic, and someone will tell you what they are and point you in the 'right' direction.

His page says they were being sold as Wharfedale 3038LB's. It's a fun approach, I think. Same driver in different style boxes to learn what they do / how they sound. Good project. =)

After a couple of years' experimentation, I'm sure he'll come around to something like this.

Funny you should say that. I do have sixteen of the things :-)

Please forgive me, but I am new here, is that a picture of a serious project, or have you just quickly edited a picture as a joke?

You may well end up with a line array. The frames of your drivers will allow pretty close placement - which is good.

Philip, it's a styling concept I drew a little while back called Bowfinger
