My Experimental Pluvia 7PHD Configuration
I have 2 P7PHD's side by side in a vented box; (the PE 0.56 ft^3 box, or about 16 L). These are in shared space with about 2/3 fill. Tuning is WAY lower than one would normally do; high 30's but I have my reasons for this. Without any bass EQ, f3 is in the mid to upper 50's; adding 2 to 4 dB from the "bass" control (40 or 50 Hz "boost") helps. This is being powered by a 25 Watt class-D amp. I have some super tweeters for 7KHz and above. This is an experimental system for office use mostly for streaming (YouTube, etc.). (the drivers are just above the laptop screen so this is a very close/near-field application). I must say; YouTube NEVER sounded so good! (I have also played HQ DVD's and CD's through the laptop since obviously streaming audio has a lot of short comings). The P7PHD does things VERY well indeed! I would say these sound as good as ANY wide-band, mid-range or full-range as I have EVER heard; REGARDLESS of price range! No exaggeration at all. I think the new voice coil probably has a lot to do with this. I would love to know how others are using these. I think I will eventually try a tall, slim tower with twin 7 or 8 in. woofers (Satori???), twin P7PHD's and a super tweeter in a DUAL D'Appolito configuration; all time aligned. I think I might try to use the Pluvias with their own custom sub-enclosures but open-back to the the tower cabinet. (I am a firm believer in avoiding standing waves so ALL of the boxes or sub-enclosures I build myself have ZERO parallel surfaces; 5 sided is a favorite of mine.)
The best part about being retired is I have all the time in the world to play around with various design ideas; some conventional; some NOT!...Cheers!

I didn’t expect so. Ot an Frugel are often misspelled, and often because of autocorrect. Just after having fixed th espeeling in 2 or 3 recent posts i thot i would mention it to save me some work.

I agree. I put one each in a 11 or 12.x Litre ported enclosure (I forget the size I made) and have nothing but good to say so far. I have Peerless compression drivers on B&C 5" horns, 4.9uF with L-pads for crossover. Also have some 20mH inductors for the P7PHD's to connect but have not done so nor have I time aligned yet.
I have to get back to them to continue the adjusting / tuning but so far just sit and listen in wonderment.
Hi all, I’m planning on trying “bowls” as enclosures for my Pluvia 11 side surround speakers, as they are wall mounted, I think the bowl shape will work nicely.
I can’t find wood/bamboo bowls large enough, I need 5.5 litres, but I can source 6 litre stainless steel bowls cheaply. My idea is to attach a ply/mdf baffle/back panel & reinforce/damp the bowl itself.
I’d welcome thoughts & any advice on reinforcing/damping the bowl?
Many thanks

Thanks Jim, they would be ideal but they just don’t have the volume unfortunately.
If I were using two bowls per speaker, to make a sphere, they would be big enough, the problem is, I only want to use on bowl per speaker, with the driver mounted in what would be the flat bottom of the bowl & the wider, open side of the bowl (blanked off) back against the wall.
I’ll probably just give it a go with the stainless bowls, I can’t go to work due to the lockdown so it’ll keep me busy (along with all the other speakers that I’ve never quite finished off
)
Without looking for my drawings, given the drivers i 1st put in them, likely a maximum of 9 litres.
The band allows you to actual make something closer to a sphere since the bowls are just a bit shallow to be a full hemisphere. And makes it easier to deal with bowls that are rarely exactly the same.
I embed the miniOnken slot vents into the band. The only one i have finished the drawings for are a smaller one for the Alpair 5.2/3.

That’s very smart thinking Dave, I’d love to see those if you have any pics?
Same size and same curout as the CHR70 so much of the work on that one sits awaiting completion.
The CHP has about 5 dB less shelf above 5k but is otherwise similar. Have you listened and formed an opinion? If you find you feel they could use a bit more top, then teh CHBW would probably be the better choice with a tiny tweeter mounted on a pod as close as you can get. I have some small ones, and some even smaller ones (a couple kinds). Scott has some experience with both of these crossed to a tweeter i believe.
