Has anyone besides me tried these yet? I’ve built two sets of five (10 total) and they are awesome. Not a lot of bass, but the mid and high end is really nice. The mid-range is perfect for HT, the voice and dialogue are crystal clear. The folks at Madisound did an outstanding job with the crossover.
I sold all but 1 to friends and they are still thanking me every time I see them. I’m using my last one for the center channel, but plan on making more soon.
Madisound recommends a rectangle sealed box, the drivers and crossover deserve a little more than that, these are 1” MDF with additional lead lining.
I took one pair to my friends, this fellow is an amplifier fanatic and been building speakers for years, he loved them.
The crossover is pre-assembled. As mentioned in the webpage, the crossover does have to be built into the speaker or mounted elsewhere.
After this set, I did find a way to drop the speakers in without cutting the notch for the wire terminal, you have to back cut the speaker hole with a router, preferable before you assemble.

Madisound frowns on a vented box for this kit
Disclaimer - Madisound does not recommend a vented box for this kit
However, just had to find out how this sealed design combination would work in a vented box. Ran it WinISD and came up with this (pic). Finished one vented box about a year and had one of each, sealed vs. vented on L & R channels - hooked up to small 60wpc receiver.
I was really leaning toward the ported box when toggling back and forth with the balance setting. Enough to build the second vented box for a complete pair.
They work well, lots of quick bass with good extension for small woofers. The xo are working nicely and the imaging is very good also.

Hi Doug,
Madisound probably had in mind crossing over to sub.
I do worse than that. I am capable of putting Qts=0,7
driver in a vented box and not feel guilty about it. I admit
to do that only with smaller midwoofers where it's still
doable to enlarge the necessary box volume without
anyone suggesting me to visit the institution for health
improvement.

Hi,
I think the answer is vented is not good enough
to not need a sub, so you may as well go sealed.
Its also not good enough to not grossly overload
with low bass run full range, something the sealed
version would survive more benignly, with no bass.
What do you expect from a circa 80Hz Fs driver ?
rgds, sreten.

The sealed boxes sounded great with high power amps and subs; but as for a stand alone, I'd go for the vented box. With a qts of .54, it's close to vented designs anyway, actually WinISD defaults to vented.
I did not notice much different in cone movement/excursion with the two boxes side by side (ported vs. vented).
*the small white birch boxes in post #3 are air tight

Well took another test with a smaller series tweeter resistor, same set up but used a couple of blankets around the test area.
They are sounding better, could use a bit more middle, which is surprising since they are 4" mid woofers.

** the blue line - replaced 2.2ohm with 3.3 ohm

Thanks Allen, This is all making sense now; why the robust bass and the reduced tweeter level - the balance is off. I never would considered it was because of the thinner profile.
I thought somebody was going suggest changing the 12uf cap or just simply remove it.
The boxes are lightly stuffed, so don't think removing 1-2 ounces of wool is going to help much.
Yes, thumbs up to flush fitting drivers and rounds edges

Speaking of vented boxes vs. sealed for the 830870, PE has a recommendation:
Peerless 830870 4" PPB Cone HDS Woofer
Definitely a odd duck, 2 of them in a .4cf box seem to have plenty of bass.
So took my own advice (again) removed most of the wool and replaced it with furnace filter material (open cell) and used a few pieces of reg. damping wool right behind the speaker magnets; which helped clear up the middle.

Hello, I too am looking for a home theater DIY setup. And have strongly considered the HDS. But how do they compare to this kit?
Seas Mimir 2-Way Speaker Kit - Pair - Parts Only

Thanks for the reply. The cost is very close to the same. The HDS is for a single MTM and the other price is for a pair of 2-ways
