Perfect for a single IXL 18

[Mr. Drifter]

hmm, was going to ask about making one for a single 12.. i would want compact though... as my boot has a pretty small opening D:

How does the wicked one design work if subs have different t/s spec.
i have an oz audio 300l sub 12 inch which winisd says can work in a sealed box, optimum 445 litres but 50-60 litres seems a working compromise. What would the difference be from a single design wicked one compared to a sealed box of 60 litres?

Thanks

It's not really an SPL box, but the high gain works well in most applications.

The design of he wicked one lends itself to a broad range of speakers for two main reasons:

1. because the sealed section volume makes very little difference to the frequency response in a +/- 20% range of volumes.
2. the semi-horn tapered port has a very wide bandwidth, which is controlled by the small section throat.

It is possible to "tune" a wicked one to suit the specific drivers used, but the results are only a couple of dB either way. For serious SPL use, there are a number of areas to create a slight peak in the response at a given frequency.

The difference compared to a sealed box is approx 1/3 octave lower extension, and about +5 or 6dB gain in the pass band.

In the new year, I'm gonna take on the WO32 I just ordered the plans online (which you can't download, they actually send you a blueprinted "template")..... so I'll be taking pics of this one....

My goodness ant, that tapped horn is quite groovy - what's the wave length of that thing?

[xMplar]

could this boix be done to hold bigger more powerful subs say 15s at 3000wrms or sumthing or is it bonly for the 10s and possibley a set of 12s

i ask as i thought about making one for the HT with sum 15s (only 1000w) and also one for a wagon or 4x4 for a no wall build of sorts any ideas

also as far as measurements go is there a set of measurement and angles to be had or seen or is it just how big you can fit in the car or house etc or is there a length width hight aswell as the internal angles

also the internal bracing in the sealed section would it be better t use a round brace like a thick wooden dowel or even a steel threeded rod instead of getting refraction of the staight MDF

the reason for all the questions is i really want to make one if it has to be 10s so be it but id like to do 12s and 15s also but i need to know a bit more info than just a picture like widths of the gaps and port areas etc etc or is alot of it just right angles using the bord devided into 4 squares then onto trinagles etc

the more info i can get the better hell i may even put an special ozzy edition ebook out of it free to mea members


(but dont worry i wont type it ill have the secretary do it as she can spll and type and use grammer)
