I have finished the pair of Seas Curv
"twins." I am very pleased with these speakers and am including some
photos of the completed pair. I used Clarity ESA caps for the tweeters,
the coils and other capacitors are Jantzen Audio as you specified. As
I described earlier, I added liner panels on the sides towards the back
of the cabinet, and wasn't sure where to put the crossover. I ended up
dividing the crossover into 3 boards - one for the tweeter on one of
the side panels, and the other two boards for the woofer on a side
panel and on the cabinet bottom.
The Seas Curv is indeed a high quality
loudspeaker, I think you may have undersold it a bit in your write-up!
Vocals are excellent, and the bass is impressive for a relatively small
woofer. The upper midrange is, to my ears, a bit close up and
detailed, yet not fatiguing, very much to my liking. I had the
opportunity to (briefly) compare them in a local audio store to the
Sonus Faber Venere 2.0, and at home with my Spendor S3/5 and B&W 601
loudspeakers. I think the Seas Curv compares well with everything I've
heard in its size and price range (say under $3K). For a small to
medium size room, I think they are excellent speakers. The CNO, which
I built previously, is a larger, fuller, and more open sounding
speaker, so I prefer it in my largest listening room.
A bit about damping: most of the cabinet is
lined with 3/4" 3-layer Sonic Barrier acoustic damping from Parts
Express. The photo shows some stuffing, but after experimenting I
decided to remove nearly all the loose stuffing except at the top
behind the tweeter. The sound with the deep cabinet and Sonic Barrier
lining is not at all boomy.
Thanks again for your wonderful designs and
