I constructed a full sized Wicked One enclosure years ago and dropped it into a '93 Honda Civic Si firing towards the rear. Enclosure ended up being 36" x 36" x 12.5" and slid right between the strut towers. JL Audio 10W6 drivers were used with something like 600 clean watts. The setup managed to pound out 159.6db @ about 60hz I believe. It was unbelievable at the time. I agree, for metal and alternative etc it was absolutely incredible. Jazz was insane as well......the "Iguana" album from Ray Obiedo comes to mind as being quite impressive.

After like 6 rebuilds and adjustments, it would play mid 20hz range up to 50hz range easily within a couple Db across the board. Could play anything and it would sound amazing and loud.

This box reminds me of some pro audio/live sound designs with a 6th order bandpass design, which include Martin audio and d&b audiotechnik dual 18” subs. I don’t know the Martin model number, but the d&b boxes that use this design include the b2 and b22. Those boxes have the fronts of the drivers directly facing each other in the back of the horn area. And the backs of the drivers are inside enclosures with slotted ports out the front. Those have always certainly given me that punchy kick for live bands as an audience member, though I’m not sure if they can really technically be called horns?

The coffin! You should also try that one with the driver facing the other direction and see the difference. Or, at least with it mounted the other side of that mounting face because the air movement holes in the chassis are being restricted by the thickness of the plastic mounting face panels thickness.

@barevids Жыл бұрын

I did actually test that before shooting, about the box thickness restricting it, and found it had absolutely no effect mounting the driver on the other face - the area of space for the rear cone pressure to escape is actually much bigger than it looks, big enough for it to be completely disregarded by the driver! This was confirmed by RTA and also impedance sweep

I was a bit confused by the word "horn", for me it is something you use for higher frequencies. And for that reason horns are kind of "bad" since they are very directional compared to a dome that can spread the sound better. But as we know lower frequencies are not very directional, but can be a subject to "standing waves" and from where in the room you are while listening. But pure pressure and air movement can always be compaired. Interessting non the less. 🙂

@@barevids I enjoy learning how different enclosures effect how a speaker plays and this season your doing is freaking awesome! You can read all day but your taking someone’s word for how “it” sounds. Trial and error seems to be the best teacher. I’ve cut and modified my simple 4cube ported box 12 times until I got the best sound I preferred. Started with a 2inch tall 20 wide port, wasn’t enough output so I went to 5 inch tall 18 wide =a lot more output but at a higher frequency so the. I extended the port 16 inches externally. Now it has lots of output and plays pretty low but falls off on the high frequency so now I’m thinking 6th order to gain the higher frequency output, but then I got to reading on tlines and I have no personal experience listening to them but I believe I will enjoy their sound more bc they’re suppost to be more accurate and go really low. But then I’m like what about the higher frequency? Should I expand the line for a horn loading effect for higher frequency? So many options but so expensive experiment. So this season your doing is right down my alley! I’ll check out the cad designs and see if I have time to figure it out.
