I received all the drivers in plain brown boxes without any literature. It was like the vendor has a bulk order of these drivers and they ship them out in their cardboard packaging. I was hoping to get a template included with the oval passive radiator. I will cut that out freehand with a jigsaw.
The cabinet cutaway drawing tells the dimensions and mountings, etc, below the images.
Tweeter is flush, all else surfaced.
I had a cardboard cutout in the boxes the PRs came in, as it rested in it in the package. However, I didn't realize this, and measured the dimensions. I listed the radius of the end semicircles and the rectangle in the middle. Treat the length as the maximum, and then cut the arcs with the circle jig. Then draw a line across the circles and cut just shy of it (with a jigsaw for example) and test for best results.

Judging by the PC83-4 datasheet, you could take this midrange and tweeter alone, without the woofer, and make a great little surround / atmos speaker that would play down to 100 Hz without issues. Thoughts?
congrats for the achievment guys.

Hi Wolf,
I'm finally getting rolling on your Purveyors! All parts needed are on the bench, cabinet cutting and assembly will be the first tasks to be done.
Couple of questions about cab construction:
Thanks in advance 🙂
I'm finally getting rolling on your Purveyors! All parts needed are on the bench, cabinet cutting and assembly will be the first tasks to be done.
Couple of questions about cab construction:
- Surface mounting the drivers is not visually appealing to me so I would like to recess all drivers and PR but not the midrange due to its flange shape. If this is done will the XO need any tweaking?
- Should any sound damping materials be applied to the interior walls or polyfill added?
Thanks in advance 🙂
Vunce,
Good to see you getting started with the project!
Btw, the passive radiator with be at the back of the cabinet - it is likely that it will be less visible?

You can recess the drivers if you like, but the Peerless is made to be surface mounted with a thin edge just like the midrange.
In the midrange chamber, I placed two slabs of Bonded Logic vertically and tight into the rear corner, and lightly filled the rest with Premium polyfil or similar to Acoustistuf. Do not pack it in tightly.
In the woofer compartment, I loosely placed about a total 1.5" thick folded, layered, or stacked wool batting vertically between the woofer and PR. Dacron or foam would likely not be as effective. Use something open-cell with wool content if possible.
Good luck on your new shoehorn! It is a tight fit. Let me know if you have more questions.

Thanks for the cabinet dampening details Wolf.
Laying out the baffle cuts and internal divider, man you ain't kidding! These are smaller than a shoebox 🤣
Side note:
I'm short one 2.5mH inductor because of Parts Express's horrendous packing job! The flat packs, small drivers and XO components were thrown loose in a large box. The box bottom opened up and the inductor fell out somewhere between OH and NY 🙄.

Good to see the progress Vunce, and hopefully you will get more done during the weekend and get these playing music soon. 🙂
Hello Wolf and all!
I too got very impressed (which means nothing as I know nothing but want everything) and took the bait…
(Late) Congrats on your achievement!
Went to the soundimport‘s website to see if I could source all in one package…
all drivers seem to be there, but the tweeter is DSN25Ti-4 … I guess „Ti“ stands for titanium, and I further guess this is not the same as the DSN25-4 you have been using?
Could this DSN25Ti-4 replace the original without changing the xovers (I wouldn‘t have a clue how to do that)?
Thank you!

According to the manufacturer's specification sheets, the responses of these two tweeters are a virtual overlay, except for the fact that the dsn25f4 has a slight rise towards 15K and then rolls off. The Ti does not have this rise. My thoughts would be since the titanium has a flatter response, it may actually not need any changes and should drop right in. The only thing I wouldn't know, is the fact of whether it sounds balanced or not with the same padding resistor values that I have implemented with the textile version. On the low end of the response, the titanium exhibits the same bump and roll off that the other one has so there should not be any changes in terms of high pass in general. I say it's worth giving it a whirl! Be advised that the titanium does not have any protection in front of it and probably could be dinged easily.
That's good for a fourth pulse in the blender I'd say 😀
Thank you, wolf_teeth, very much appreciated!

Wolf,
What is your recommendation on placement - do they need to be free-standing on speaker stands? I ask the question because they are vey compact and can be placed on a console top too.
Is it safe to assume that tweeters show be at ear height? And slightly lower, a little upward tilt might do the job?
