Building a Monitor?

Erm i had a magazine on how to build your own monitors. Pity its gone missing. Have u tried searching the internet? I wanted to build my own cab and did some research. There's loads of sites.

There's also loads of freeware programs where u enter in the parameters of the speakers u have and it calculates the correct box dimensions for both closed and ported.

Just look around. Sorry i couldn't be any more help.

search under amps for "cabinet building 101" or something like that...lotsto learn there.

 

Try this link:

Download the "winisd" prog from the bottom left hand side of the homepage.

Monitors, though, have angled sides. I've no knowledge as to how the "Golden Ratio" as used to determine the proportions of the usual cube-style box can be modified for angled sides. But I'm certain that a number of other guys on here do.

This site helped me alot.

Probably want to port it and put in a crossover and horn.
For wiring. It's probably best to just put 2 jacks wired in parallel. You can run at least 2 on each side of a power amp 4 if it handles 2 ohms. (I don't know of any that don't go down to at least 4 ohms and a lot go to 2)

 

I agree with Player. I've used the site, too, and found it really good.

This isn't exactly about Amps, but the speaker gurus(Joris, Bgavin, etc) over there would be able to help you. That's why I'm moving it.

 

If it is a bass monitor, the shape is of no consequence. The waveforms are far too long to cause standing wave problems inside the cabinet. Build it any shape you want.

If you want golden rectangle for appearance, that is fine also. Use the Windows calculator in scientific mode to find the cube root of the volume, and find the approximate golden dimensions as 0.618x by 1x by 1.618x, where X is the cube root.

You can run a monitor as a sealed box, as there is no real need to have full bass extension. This will give you a smaller box than a ported one, plus it will have the natural driver loading and protection inherent in a sealed box. And without measuring or calculating any port tuning.

There is a very nice sealed box calculator here:

Actually, three 8 Ohm cabs in parallel equals 2.67 ohms

because others are even better at this than me, a little digging... *rummage, rummage*

What kind of speakers are they?
You can probably find the parameters on the web somewhere which will help with any of the design calculators. You'll get the most out of them by matching the box to the speakers.
