I have seen this princip before:OB and bass reflex,as DIY.Can't remember where.

Isn't it a slot for loading, i.e. Increasing system q thereby redusing need for eq? (And not bassreflex port) 🙂
I like the look of this one, Gainphile.
Can you supply any details?

Has this been posted here? An OB array...
An externally hosted image should be here but it was not working when we last tested it.

I do not know the princip,but if it is a slot loading , this one looks very nice too mee.

Does he have to wear a seatbelt? 😀
My emerald physics cs2 clone.
With passive filter and mid correction. Active bass correction with Rechhorn B1.

Other than suffering a broken neck from trying to view the picture, that looks like a well done project!

I had/have some upload problems with my ipad.
Pictures are out of perspective.
At least I'm not the only one... mine never show right side up eother.
Nice work though. Would love to hear the CD/15" combo.
It depends on the angle of your iPad when the image is taken.
I realize this. I had an issue with an ad I posted. The photos show very much upright but for whatever reason the images posted sideways. I tried and retried before finally giving up. Oddly enough when I first got this ipad, safari wouldn't allow me to post attachments at all on some forum boards.
finally finished the cabinets for my new speakers.
the prototypes looked like this:
and the finished product.
still working on the crossovers, but it sounds good so far!
going to make some grilles as well 🙂

A thing of beauty! 🙂
thanks!
it was my first try at veneering so i'm glad things turned out as well as they did 😀
added some grilles today

Marvellous.
Did you hand veneer these?
yep. it took quite a while as there was 28 different "sides" per speaker to veneer, and lots of corners to sand 😀
i used paper backed veneer and the PVAc/iron method.



Thumbs up, Bjarne!
Please give us some info of drivers and xos, measuremennts to come?
tweeters are RAAL 140-15d dipole-AM with the autotech SEOS waveguide, mid is a jantzen ja8008 and woofers are Seas L26ROY.
the crossover is not optimal, and perfecting it is next on my to do list.
i just have to read up a bit of passive XO theory 😱
right now the bass and woofers are actively crossed at 240hz LR46 and M-T crossed passively at 2500hz LR24.
i havent measured the speakers with the finished cabinet yet, but i did a quick 0-70 degree measurement of the prototype in my livingroom before commiting to the final design.
the mic was placed 80cm away from the speaker, aimed between the mid and tweeter.

as you can see, it still needs some work, but i like the sound so far.

LR46 on the woofers and bass? :O
If it becomes an issue you can always go the hybrid route, you have consistent dispersion so global EQ would solve most of your issues.
