Default ENVIRONMENTAL HIGHJACK

Guys, fellas, burning the boxes is fun but if you wet them down with detergent ansd some Nitrogen fertilizer MDF and chipboard mulch down in a few years and enrich the soil.
It just takes time and patience, sorry to butt in; but all this talk of burning is a little tree unfreindly.
Here in Oz we are 8 years into a 3 year drought and it is starting to get a little scary, Melbourns is on severe water restrictions and we may actually run out of water in 2 years;- please don't make it worse.
That said I use a lot of MDF, chipboard and ply.
regards Ted

Point taken, but I suspect the numerous coal-fired power stations that are being put up at an alarming rate in China (to cite one example), might have more environmental impact than Dave & a few DIY audio fans torching scrap speaker-cabinets.

I am so very happy I found this thread, and I'd like to extend my greatest thanks to Dave, Scott and Martin for publishing their terrific work here. Amazing stuff!

Since I am not into speaker construction at all myself, I really have to ask...

I want a foot on the small Thor. Part because I think it looks good, part because I don't want it to flip over. I also would like to hide the filter parts in there. Here's a rough drawing on what I'm thinking. Now the question arises: What to to with the tube? Is it its length that is important, or is it how much of it that is actually inside the box? I.e. Is A or B* the correct way to go? Or is there a C out there?

*B does naturally require the foot to be hollowed out, whereas A is a solid foot.

Not being an expert in any way......I'll take a stab at it and say "C" is the best answer. Because:
Both "A" and "B" would require the port exit to base at least ~2 inches off the floor to work properly. I built a down-firing sub and it's minimum was 3 1/2" (Works Great!). I think the sound would be "Boomy" if the floor is hardwood / laminate or muffled bass if it's carpet.....I presume carpet due to the spikes.

How about a rear firing port? Although it would tend to
boom as well unless the speaker was placed away from the wall.
That's why mine are front firing........WAF.......don't 'ya know......
At some point in the future I'll remove the Xovers from inside and make a box to sit outside (good idea) and make some 2" Granite bases to sit under the MDF base thats there now.

Like I said, I'm no expert here, so wait for someone else with more experience in design.

As long as you have sufficient room below the port to not affect its functioning (probably 3" in this case) A is the way to go... less than that, take it out the back, side or front.

Thanks for the input.

Perhaps a more sculptured foot then - with a box in the speaker itself!
The arch of the foot will be at least 75 mm, and instead of spikes use foam dampers. Probably a lot better anyway.

Which brings me to another question..
I just have to draw it to explain.

Thoughts on this btw?

Looks good to me... how high is the tweeter from the ground now?

That would be approximately 109 centimeters, or just less than 43 inches.

That might be a little high. Or...just perfect.

depends on how tall you & your listening chair are. 33-36" is about right for me.

Yes. I'm leaving that path. I believe it will be too high. Especially if...:

Inspired by the Amphion Prio, I was thinking about moving the drivers.
I think it looks better to have the drivers as far to the top as possible.

Would this adversely affect the sound?
I'm not sure - that's why I'm asking - but I suspect this would probably change the characteristics altogether.
