will the HiVi M3N's work in the Needles?

Re: will the HiVi M3N's work in the Needles?

this is a needle with a b3n. baffle is 3/4" pine, stained to match some of my parents' furniture. sides are black using rustoleum epoxy spraypaint.

Those look great! Thank you for sharing. I also plan on doing a black sprayed on back and sides, though I am going to use a countertop laminate for the front. If I did not have the laminate available (leftover scrap, so a freebie) I would have loved to do a stained veneer on the front.

they wont be pretty, but ill post up some pics tomorrow

Hey Nik,

Any pictures yet? I hope to finish up my pair withing the next few days. I'd like to see some others before I decide on a finish! Maybe I'll get some more ideas...

So- you gonna post pics of your Dragonflies?
Glad you like 'em!

i am very impressed so far. I hope to finish the ther one tonight or tomorrow.

I am amazed how good the high end sounds w/o a tweeter, and a good amount of bass comes out the port. I just have to figure out what to do with them, as I now have about 4 pairs of speakers w/o a home (lol)

Thank you! So- you diggin' the results?

Re: will the HiVi M3N's work in the Needles?

cool, i stuffed it up flushwith the bottom of the divider. I did not do it before construction, so i kinda just shoved it down with a stick, but i think it worked.

One is all done and i am listening to it and it sounds very nice.

Good job on that filter wolf. I did a big terminal that uses a 3" hole, so i fed the crossover in that way and screwed it to the divider.

Re: will the HiVi M3N's work in the Needles?

stuffing is against the front baffle, dense at the bottom and thins out slightly as you go up. if you use little dowels, you can try taking it around the turn. i think i ended mine at the top of the divider.

Re: will the HiVi M3N's work in the Needles?

I believe the stuffing is added in the line all the way to the bend, where it is thinned out in the turn. I thought there was a pic of this somewhere on this thread - if not, I can probably find one.

Re: will the HiVi M3N's work in the Needles?

well, i finally got around to building 1 box for my needles.

I ended up makinf the slot port 2" long, so we will see how that goes

1 question, in this inclosure, do you add stuffing, and if so, where?

I should have the cross over together soon, so i can report results as soon as i know about the stuffing issue

Re: Ka-Ching!

Yeah- power-rider is right. The plots stop at 20kHz, which means the FR is about 3-4dB down at 20kHz but only from about 18kHz. It's fairly extended.

That filter really does do a fine job.

I'm just tickled Patrick took this on, and feel it might be a very viable little project.

Keep us posted on your progress! Whenever you get to it....

Later,

It looks like all of those plot lines end at 20kHz.

Re: Ka-Ching!

The boost in his response and my box model are very similar, and should not be an issue to make a difference. Also- the contour I used does not include BSC, it's for the resonances only, as the tuning took care of BSC. The notches smooth out the hump in the midrange and the material resonance up high.



Patrick used the DF filter on his experiment, so just use the DF filter with the adjusted port tuning in the Needle boxes.

I'd like to hear these someday!

Wolf - that contour certainly does a good job at taming things down. I can't see because of the "Filter" button, but what is the upper-end frequency response on your sceenshot? Do these go up to 20khz?

Because of my work travel schedule for the next month, a quick build is unlikely. Perhaps in a few weeks I will have some time - if nothing else, it will give me time to think about the cabinet exteriors!
