Hope this helps
Thanks for your input. The Fenrir would be for my brother in law.
I've diy'ed a few myself that are not shabby and I enjoy the process. I''m certainly not at the level of Wolf Teeth, but I have fun and usually end up with something that is listenable. I guess you have used the RST28? If so, what's your take on them?


Thanks

While I've not used any Seas teeters myself, I've heard quite a few. In terms of extension, I think the Wavecor has the Seas licked. Not every 22mm tweeter has a 750Hz Fs. Elsewise, compared to say the 22TAF/G, I think both are great 22mm examples.

I know of no actual designs with the RST28 series. They are just too new to have something completed yet.

Later,
Wolf

Default Question for Wolf

Wolf - I am in the process of building a pair of Fenrir speakers and have a question for you.

I am trying to reuse an old AR15 cabinet that is 18 liters (or 19 liters). The overall outside cabinet dimensions are as follows:

21.5" H x 11.75" W x 8" D

I used the attached recommendations from Rival Acoustics to space the drivers on the baffle.

Questions - Do you see any issues I may encounter with my implementation versus your design? Also my inductors are a bit further separated from the ones you posted in your build and I wonder what effects my layout might result in versus yours.

I plan on adding some additional bracing in the cabinet as well.

Thanks,

gabkw

Your layout should be fine as long as it's wired correctly. The only reason I did mine as I did was to get them to fit in amidst the braces. I see you have the 0.1mH and 4.7uF quite a ways away from the woofer, and yet they go across the woofer, so I'm just making sure they are in the right place.

Since you superimposed the baffle atop the box just as I did, you'll likely end up pretty close.

You are venting it, correct?

I was planning on locating the woofer terminals right next to the tweeter (i.e., on the top of the woofer if you will) so that they are fairly close to the the 0.1mH and 4.7uF below. In looking at it again, I actually have the space available to push the 0.1mH even closer to the 4.7uF and therefore almost directly under the woofer terminals.

Yes planning on venting it as per your design (~ 8" over all length).

Thanks for commenting Wolf. Its good to know I haven't gone off too far adrift that crossover changes would be required.

Default Cabinet volume

Wolf - another question regarding your cabinet volume of 18 liters or 0.636 cu'

Is that the final resulting internal volume that includes all your bracing, vents, crossover volume, and driver volumes?

OR

is it the internal box dimensions you started with before adding the vents, drivers, crossover, and bracing?

I just measured and my AR15 internal volume is exactly 18 liters, so I am trying to ascertain how much additional bracing I can add before the box becomes "too small". It really needs some and I'm willing to add it if the only degradation might be a few dB on the low end. Your thoughts?

That is the gross volume of the enclosure, plus about an 120in^3 to account for some extra bracing and such. You will likely be fine at the 18 ltr mark, just lose about 5Hz or so on the bottom.
