During December 2001, after several months of building, I finally
completed my main speakers.
The cabinet is built by Martin Electronics in Burlington Square;
although it is costly, I find it worthwhile as the quality is very
good. The 1½" thick MDF, as well as the internal bracing,
reduces the vibration of the cabinet by a lot compared to conventional
cabinets. It measures to 10" by 12" by 14" on the
The drivers used are Scanspeak
D2905/970000 1" soft dome Tweeter and 18W/8546-00 Kevlar
7" midbass Woofer, both ordered from Leda.
The crossover uses Jantzen
Cross Coil Foil Inductors - from Leda
also, and Solen
capacitors - brought from Well Audio at Burlington Square.
I use 2 inductors, 2 capacitors and lots of resistors for
I use silver-coated Teflon hookup wires I got from B &
Lee at Sim Lim Square for the internal cabling. 18AWG wires
for the woofers and 22AWG wires for the tweeters.
The crossover is placed at the base. A piece of a 2½"
thick acoustic foam is then placed over it. Another piece
of acoustic foam is placed at the top of the cabinet. For
the rest of the same spaces, I stuffed cotton wool. Although
from the outside it may seems like a big speaker, the effective
volume left is very small, thanks to the thick MDF and acoustic
|Instead of using normal binding post or bananas as connectors,
I use Speakon® NL4MPR from Neutrik
- 4-pole connector, just right for bi-wiring or bi-amping. The
corresponding cable connector is NL4FC. This connector is sometimes
seen on professional PA systems. The advantage for this connector
is that you do not have to worry about the polarity, touching
the + with the -, thereby no blowing of amp, or having hands
touching the bare wire.
I use a single run of Belden
1585A as speaker cables. This is a CAT 5e cable which have 4 pairs
of twisted pair in it. Each individual cable is Teflon insulated
and is 24AWG. The outer jacket is Flamarrest. I use it because it
is very cheap and good.
stands are Atacama
SE24 which I got from Electrades.
They are half-filled with sand which I got from Electrades
In total, I spent just below S$1500 for the components for the
speaker, excluding the stand.
The speaker have always be the "reference" for my friends
whenever we have a AB shootout for any other components for these
pass years. We have always used it to AB gainclones, cd players,
pre-amps, cables. As it is able to reproduce down to below 40hz
flat, there is no need for a subwoofer.
When it is not used for ABing components, I hook it up to my AV-amp
to enjoy watching movie or listening to music.
