"There are only a few real contenders to the NSMT
10S in the sealed mini-monitor market.
The Harbeth
P3ESR [$2,195]
which uses a 4th order crossover (I prefer a simple 1st order
crossover for reasons that you are already aware of) and the
Merlin
TSM [$4,180] which
performs well at 9- 12
distances, but not as good as the NSMT 10S for nearfield or extreme
nearfield listening positions."

Erol,
I am enjoying my Chorus speakers, still experimenting with them
to get the best out of them. The bass is too strong with the
ports open, but a little thin with the ports sealed. My best
option may be to augment the bass with a small sub placed in
the corner of the front wall. That way, I should be able to dial
in just the right amount of bass to get a full sound without
it becoming boomy.
I thought that you might be interested in seeing what I have
done with my NSMT 10S Speakers. I acquired these speakers a couple
of years ago, (used) in the Walnut finish (shortly after the
Walnut finish was no longer available from NSMT). I sent the
speakers back to you for refitting with the new Seas Woofer and
modified crossover.
The original finish on the cabinets was in pretty rough shape
(abused by the original owner), so I decided to re-veneer them.
Before deciding to re-veneer them, I had done extensive experimenting
with bi-wiring vs. single wiring with a variety of high grade
speaker cables, and although the differences between bi-wiring
and single wiring were very slight, I determined that there was
slightly better coherence of the drivers with single wiring.
So, I eliminated the second pair of binding post, modified the
internal wiring of the crossover/drivers/binding post (using
DH Labs OFH-14 14ga. Teflon insulated, silver-plated, stranded,
high purity copper wire) , epoxy filled the unneeded binding
post holes (as well as the baffle grill post holes) and re-veneered
the entire cabinets with some premium bookmatched Walnut veneer.
The binding posts have been upgraded to Cardas Copper SSBP. To
further dampen cabinet resonance, a very thin layer of rubberized
cork has been bonded to the internal surfaces of the cabinet.
A small amount of natural long haired wool, purchased from Madisound,
was added to the cabinet interior. (Natural long haired wool
is preferred over the synthetic material (Acousta-Stuf) because
the wool fibers are all of different lengths and absorb a more
diverse band spread of frequencies.)
The baffle around the tweeter is fitted with diffraction felt
pads purchased from Jim Goulding at Diffractionbegone.com. (The
naturally grey felt pads have been dyed brown to more closely
match the walnut finish of the speakers.) These really help clean
up the high end and prevent smearing by eliminating
baffle reflections from the tweeter. The speakers are securely
mounted to custom sized Walnut mounting plates I made which sit
atop Core Audio Designs speaker stands. (Small bolts are run
up through the mounting plate, with a thin layer of rubberized
cork sandwiched in between the mounting plate/speaker base and
pulled tight.) The speakers are firmly coupled with the mass
of the stands and gone is the fear of them being toppled from
their perch.
Anyway, here is what my NSMT 10S (Audiophile Edition) Speakers
look like now.
 
My NSMT 10S speakers are used in an extremely nearfield listening
position with a Adire Audio Rava 12 sealed cabinet subwoofer.
Integration with the sub is completely seamless. Source is a
Rega Apollo CDP, amplification is provided by a Red Wine Audio
Signature 30.2 Integrated Amp providing 30 watts RMS per channel
into 8 ohms. Interconnects between the CDP & Amp are Artisan
Silver "Ultimate Silver Dream" pure silver wire, terminated
with Cardas SLVR RCA plugs. Speaker cables are homemade, constructed
with VH Audio 18 gauge, solid Core UniCrystal OCC with foamed/cellular
Teflon insulation, configured in a twisted pair and wrapped in
100% cotton sheathing. These cables outperform any multi-stranded
cables I have ever tried.
I obtained my N.A.R.A.S. recording engineering certification
back in 1975, and although I did not pursue the music business
as my profession, I have been an avid music lover, audiophile,
and audio equipment hobbyist/tweaker for the past 40 years. In
that time, I have owned and have had the privilege of listening
to many fine speakers. I still own Bang & Olufsen Penta Towers,
JBL Studio Monitors, DLK Monitors, and an extremely modified
pair of Magnepans. But my favorite speakers out of the bunch,
and the ones that I enjoy listening to the most, is my NSMT 10S
setup.
When I really want
to hear the mix that the engineer intended, the NSMT 10S speakers
are what I use. The midrange tonal balance of these speakers
is near perfect. As I have always said about speakers, if it
cant do voices right, nothing else matters! The NSMT 10S
speakers do voices right!
As far as imaging, none of the other speakers I have can do what
the NSMT 10S can do. On a good recording mix, vocals and bass
are solidly planted in the center and all the instruments are
spread across the soundstage and have their own place in space.
The sound does not seem to emanate from the speakers at all,
but hangs in the space above and between the speakers with a
depth that extends several feet behind the front plane of the
speakers. When positioned correctly, the NSMT 10S speakers are
able to project a 3D holographic soundstage. With most speakers,
you hear the drivers, but with the NSMTs, you only hear
the music.
You did a fine job designing the NSMT 10S speaker Erol, and I
just wanted you to know how special that I think these speakers
are. I cant imagine any other speaker sounding better in
an extreme nearfield setup (although someday, I would like to
audition the NSMT model 20M).
Best regards,
