Yeah whats the response plot with any drivers? Anyone tried these yet seems an easy build? No response from the designer? Thanks! :think:

No need ;)

Hello,

This is the frequency response as hornresp predicts:

Unfortunately I have found that hornresp (and akabak) are a bit pestimistic when it comes to predicting the lower frequencies for this type of enclosure. I'm eagerly awaiting the day that the Dutch weathergods give me a day without snow, rain or temperatures below 5 degree Celcius.

The measurements show a 10 Hz improvement in low cutt off but were indoors (related to a 18" basreflex, to pick out the room nodes). As such, you probably understand I will only send those measurements on request. As soon as the weathergods show me worthy I will show real half space measurements on the plan-section.

As from usage with parties I can tell that it will go louder then a 18" reflex with less power, keep up and sound like it's hitting those low notes just as hard. A commercial version is in the make, same design, new goodies.

Regards

Here some pictures of the newer measurements, including results.

The initial measurements were outside;




On occasion the wind blew that hard that it rose 40 dB in level (how is that I have angered you, mighty gods of weather), interfering with the measurements. So I went inside (450m^3) and threw some other cabinets into the mix (Cubo15 is in the middle):


As it was inside, I had to correlate the measurement of Cubo15 directly to the 18LW1400 basreflex (same spot, same influencial nodes, same voltage), thus showing the gain over the basreflex:



On request some other pictures from Cubo15 (build by someone else);





Regards

Cubo- Great design, considering a couple of these after i finish some current project. But what really caught my eye was your computer case, been thinking about something like this for a while, looks good

is it possible to upscale this cabnet to suit a deltapro 18A. 18" speaker? I think i will build a pair of 15's anyway, but an 18" version would be a great Idea for me.

Cheers. smiley20

@MAutopsy: Thanks, I can highly recommend it! Gives much more freedom in transport and events, might even have a little bit of advise if you'd need it ;)

@COZY PILLOW: If you mail me I'll see what I can send you. I'm not sure how it will sound. I didn't like the 18LW1400 that much above 80 Hz in the previous prototype but the V18-1000 has been loving it. With a small adjustment the Delta Pro simulates smoothly.
