After quite a while I decided to make my own speakers I just got the speaekrs this morning and installed them, I just need to decide what colour to do them the only colour I think can look good is matt black.

I'm waiting for...... "what's a crossover" ..... LOL......

"What could be different? They're just speakers." ...... Classic .....

Enjoy them..... High Gloss black to answer the question....
 
Why do the dimensions look so similar to a shoe box?....

....and why such a large bass driver in such a shallow box? Never mind.

Use MDF sealer/primer before painting. You need a tough finish, so an enamel spray paint would be good - or Hammerite. Classic gloss black, or Hammerite red as colour options
 
So did you properly design them? Or is it a box+ drivers + crossover = job done ?

Yep, although for some reason the crossover is giving the tweeter full range so I have to replace them before I can start using them properly.

Now you just need to build some double 18" bass bins to go with em

I'm going to be making a 12" sub to with them! Although after hearing them for the first time I don't know wether it would be neccesary so I might just go with 10"!

Apparently those dimensions are optimum depth, length all that and of course the volume!


I think that goss balc is going to be the final colour although I think that matt black would look good after saying that, if I had the skills I would use streched black leather as suggested on another forum. I really don't know wetehr they would look good or not!
 
Optimum depth, but for what cone size? ;)

I'd have done a ported rear option if depth was a concern.

I would have done but the optiumum port size was 400mm long! and I wasn't to bothered as this design gives almost exactly the same frequency response.
 
Did you click to find optimum ratio in your simulation software, WinISD? It usually gives a shape a bit like that. Looks like Monacor drivers? What did you sim the crossover in or is it a ready made one with generic slopes? You appear to have flush mounted the tweeter, why not the woofer? With full range going to the tweeter (why is this happening!?) it'll overload VERY easily!

I can assure you designing and building really good speakers is very in-depth and complex, involving measuring, computer simulations of every aspect (driver responses, baffle step, enclosures, crossovers etc) and trials. You may get a decent result with less effort, but never anything exceptional. These are fairly budget orientated drivers, quite easy to work with too, but you could probably get more out of them.

You can get a whole range of vinyl,wood effect, stone, colours, high gloss etc. Seal the MDF (3-4 coats of Rustins) first and sand it with high grit paper, you'll need an extremely flat and smooth surface to get decent results with a gloss vinyl, less important with wood effect/matt colours :)

Suprised no one has asked this but how do they sound? Do they sound better than what you had before?

Good on you for having a go at a project such as this. As long as you got enjoyment out of making them and they sound ok then job done I say. I can't help but think some of the replies to your post have missed the point somewhat.

Okay the full range is going to the tweeter or most of the sound because of the crossover for some reason and it is a pre-built generic peice of crap after having a listen the woofer is getting up to 8KHz too but not to worry as I have been on the diyaudio forums and they have sorted me out a good design.

I didn't think the woofers would look right flush but thinking about it i'm not quite sure now, perhaps next time!

I realize the amount that goes into designing the enclosures, I have been interested for the past few years now and havn't scratched to surface!

They are Moancor drivers and I like them I think they look okay too!

They sound good at mid volumes when you can't hear the distortion from both drivers, I am now not using them becuase I don't want to damage the tweeter with the crossover I'm using. I have enjoyed and the next lot will be much better! Thanks for the feed back!
 
With the right crossover these have decent potential. Monacor make nice drivers for the money, there's nothing inherently wrong with a box this shape so long as it is of correct internal volume, I also like the sound of sealed designs more generally.

Do you have wadding and/or foam inside? This is important, especially in quite a flat design like this, to limit reflections back through the cone. It's a PP cone so is more immune than some to this, but being a sealed design you can stuff plenty of wadding in, no port pathway to potentially block.

Feel free to link your DIY Audio thread here, I might not have much to offer on passive crossovers but I'd like to look over it anyhow :)

BTW, vinyl covering will be hard as you've applied a roundover to the top and bottom as well as the sides. Go for paint tbh, matt/textured finish is easiest.
 
Yes I think that matt would look better anyway.

I have ordered some wadding and should have been here today although I did have a bit in there.

HEREs the diyaudio thread although I think I've got it sorted now!
