    They don't need to hit 20k or go deep for HT though. DS90 or DSA90 might be good options too. The RS100 does handle a little more power.

    I suppose an RS100 would work for surrounds, no? Any thought as to the PS95 vs RS100 for sounds from those who are more knowledgeable than me? They have the same overall diameter and cutout diameter

    Just went by Target

    For reference, the outer diameter of that pot ^^ is 5 and 1/8 inches, and the inner is 4.5"

    As for the septagon (not heptagon ;) ) Joey is using, the outer diameter is roughly 4-4.25" and the inner diameter varies from 3.5-3.75"

    Absolutely! Will report back in an hour.

    As far as using it sealed in a surround application to 100hz, absolutely possible and maybe extremely well suited in my opinion. I tested this quick dirty sealed ps95 setup tucked in the corner of my kitchen floor to see what it sounded like with boundary reinforcement and I was happy with the response, definitely better than a nonfiltered nd91. Way better top end, midrange cleaner and surprising extension. I know you don't plan on really getting that extension for the application you describe, but am highly optimistic about porting this and what it will do for the bottom octaves.
    We can probably dial it in. I'm playing with the driver in winISD now.. Any chance you can fill the enclosure with some sand, rice, beans, flour or something else.... Give it a few taps to make sure it's all settled, then dump the contents into a measuring cup, then tap that to settle it in order to get an idea of it's volume ?

    Yup Balance by reduction. Particularly on drivers that are not "optimum" for bass and don't have high sensitivity to begin with .

    MSN, I'll get a pic up in a bit. The edge of the ps95 sits just about tangent with the sides. Almost like it was intended for the purpose, it's that close.

    For surrounds I probably wouldn't mess with BSC as there is little to no low frequency content. I would want the sensitivity, and might even try to find an even louder driver that handles more power that could fit in there. Maybe a W3-2141 would work.

    Since Target is not really a competitor to PE I figure I can link here. Target also has these other flower pots (Joey's is sold as a flower pot) which might work with other drivers:

    This shadow box could be used to make a mini atmos ceiling speaker...

    Joey can you show a pic of the enclosure with the PS95 in it? Does the rim of the driver go past the edge of the enclosure?

    Joey, I'm might try these with the PS95s as surrounds. Do you think a BSC circuit would help with the low end? For surrounds, based on your experience so far, crossed at about 100hz, do you think they'd be fine as-is, sealed?

    Nice find on this!

    Most 4n "nominal" speakers drop to 3ohms at a couple spots in their imp plot. W/that 8n parallel resistor, THIS one maintains at least 4n - you could almost call it 6n nominal.
    If you KNOW your receiver won't like that, you can swap that 8n resistor for 16n (or 15n) and you'll maintain at least 6n across the board (i.e., a nominal 8n speaker).

    AFA the top end goes, you COULD add a 0.25mH series coil between the parallel resistor (to gnd) and the driver, but first I'd probably just see if you can enjoy them enough just by listening to them a bit off-axis.

    Hahahah that is funny. I've been looking at small wooden bowls, boxes, and all sorts of things the last few days to use as strange enclosures for a set of small speakers I want to build for a gift. Those cups were one of them! As far as making an ND91 sound better.... Some BSC shaping would help. When I was looking at those cups, one of my thoughts was putting these on top and going 2-way.

    Paul, it's exactly what I thought!

    Thanks Tom! For the cost and time savings, priceless.

    Ryan, I do have some 1/2" diameter straws in the house.....

    The ps95 sounds soooooooo much better and doesn't seem to give up as much low end as I thought it would to the nd91. Also gets a bit louder by my ear test. 🙄 I think the ps95 may be a fantastic mini BT option.

    Next is porting this thing.
