ND65-4 Vented build

Re: ND65-4 Vented build

hahaha i'm going to apply for a mod spot over at road food, wish me luck. the elevating trick is just going to simulate "feet". sort of vaguely referenced in my first post amidst the randomness. you find it quite often in the little "subwoofers" that come with computer 2.1 systems. it just lets the sound radiate from all sides, which may "thin" the sensation of the bass but may also make it less "directive" ie "why does it sound like it's coming from the back?"
i have a 15" subwoofer done essentially in the same arrangement as your box only much much larger, but the basic nature is still the same. this is why i asked my initial questions...to see if i was just being a nutter and over "tweaker" or if other folks with similar arrangements noticed similar things.

Re: ND65-4 Vented build

I added a few coats of pure tung oil, which dries to a matte finish. its a little hard to tell from the photos, but its definitely a richer look to the wood than just the dyed stain.

I will have to experiment with elevating them and seeing how it sounds.

forum threads in general could probably benefit from more silliness.

Re: ND65-4 Vented build

i think the finish came out incredibly well, that neat method of dyeing really did the trick. have you thought about the possibility of a clear coat at all?

Could this actually be the case?

it could be. you have put quite a bit of work into these and they look great, so it would be ridiculous for me to say, "hey, cut this or that to experiment" so i won't. (especially since my original silliness was more than any thread really needs) you could however try something like 1/2" or 1" temporary risers under the "legs" of the cabinet and see if you still experience the same effect as you do now. you may find there is more "emphasis" in your current configuration.

Re: ND65-4 Vented build

Complete! I used the Dayton DTA-2 amplifier board to power the units and integrated it into the back of one of the boxes. The units sound pretty impressive for their size, but bass is lacking from across the room. Up close they sound much better. I like the suggestion of pairing these up with a voxel. It may be my imagination, but the bass seems to resonate from the back where the port vents, though it could just be the mid and high frequencies don't sound as loud from the back of the speaker, so the bass only sounds amplified.

Could this actually be the case?

...count me in for looking forward to the finished pics as well.

Re: ND65-4 Vented build

Rounded edges and sanded.

I want to stain the wood, but was looking for a clean, green, low (no) odor stain. I've read about people having trouble getting stains to look right on poplar (it being somewhat green) but have heard good things about staining the wood first. I came up with the following solution after researching other DIY stains online.

I stained the raw wood using red wine. One coat and let it dry.


I then painted on a solution of 1 pint apple cider vinegar and one torn up piece of #000 steel wool. After a week, I took out the remaining hung of steel wool and was left with this:


I painted this over the wine. Something about the tannins in the wine and the vinegar solution create a brown dye...it actually changes color in front of you. I plan to finish it with tung oil, which should help bring out the color a little more.

very nicely done and an interesting work around for a "green" dye method. count me in for looking forward to the finished pics as well.

Re: ND65-4 Vented build

Very clever and creative idea using wine as a stain/dye. I hope you saved some to enjoy a glass before using it all on the cabinets! Looking forward to seeing how these turn out after the tung oil finish

Re: ND65-4 Vented build

Let me do one more test and I'll share the results. Just want to make sure it works the way I'm hoping! Poplar can be difficult to stain, from what I've read, so I want to be sure it looks ok before sharing what could be a terrible process.

it takes stain just fine, it's whether or not the green comes through. 'tis why i'm interested.

Re: ND65-4 Vented build

i think it's a neat little project and would be interested in your staining process if you'd like to share

Re: ND65-4 Vented build

A 3/4" port tube only has an area of about 1/2 sq.in. For this one to have its Fb altered, I think the distance the "feet" lift the bottom off the port end would have to be something like 1/8" or less. It LOOKs like he's lifting it maybe 1/2" to 3/4".

Why be concerned about phase when there's no XO involved?

-port
again this was all questioned regarding someone else's real world experience.
-phase
for nulls. again, on paper x happens, im curious what others find in their projects.

perhaps the "tone" of my original post made it appear i was being mocking or something, i wasn't. the silliness was for the sake of silliness.



"green like the poplar these speakers are made of!"
LOL! i think it's a neat little project and would be interested in your staining process if you'd like to share

Re: ND65-4 Vented build

For my own ignorance, would it have mattered acoustically if you would have closed the back and opened the front for the port mouth?
