Ex the SAMSUNG Sub Woofer Model PS-WC45T which is designed to "mate" with the sound bar model HW-C450
The PS-WC45T Sub Woofer switch-mode power supply "blew it's brains out" which resulted in a now dead little subbie.
I wanted something different anyway, so the PS-WC45T ("Kid Subbie" to most folks - it is small for a subbie) was placed on the operating table with a view to not servicing it but removing useful parts for other purposes ...
As a result of this operation, this loudspeaker was finally extracted - not an easy job!
You see, Samsung make access to the electronics (via the rear panel) easy but getting to the loudspeaker is a different matter. The whole front of the sub-woofer box (with the cloth grill) is indeed removable but it's tough going ... the front panel frame is all moulded plastic with push in plugs BUT SAMSUNG have decided to add a drop of adhesive or two on each push in plug to make life difficult for people who wish to change the loudspeaker. After some effort and once the front panel is removed (it takes patience and gentle prying of the points where the plastic plugs are located but eventually they "give up" and come free) you can then unscrew 4x normal old screws and the loudspeaker then releases from the cabinet.
This loudspeaker would be handy to replace your own in a PS-WC45T (I have seen these accidently been kicked in the front or the dog got hold of the grill and destroyed the cone in the process - it happens!) OR make your own little sub woofer, perhaps this time an analog version with some sort of low frequency filtering would be nice.
I was initially skeptical of the claimed 200W+ power capabilities of this loudspeaker but this does seem to be correct. Inside the PS-WC45T, on one of the two internal PCB's is the audio amplifier chip, an incredibly small device (for the stated power) but then I realised this is no ordinary "analog" audio amplifier but in fact the audio chip input is dealing with a PWM signal (not analog) and the power output is using MOSFET's running in Class D - it's one of "THOSE AMPLIFIERS" a digital amplifier. This somewhat "magical' audio chip is the TAS5614LA and it is this that is directly driving the loudspeaker I am offering.
If you are interested in further information about this little (and I mean little) chip from TI (and who wouldn't be?), take a look HERE
That's enough of the background to this loudspeaker, now down to the description
UNKNOWN ORIGINAL MANUFACTURER - Loudspeaker
Country of origin is unknown (most likely China or Korea)
Part # 0100-019998-1 PB04 Y1A
Here is a photograph of that part number
No amount of searching reference sites online provided any information about this part number 0100-019998-1 PB04 Y1A - I am pretty sure this is a 3rd party loudspeaker, sourced by Samsung and those numbers are their own internal part coding.
Also supplied is the original interconnecting cable between this loudspeaker and the PCB in the sub woofer.
Black finish all metal basket
5" cone
Rubber surround with what appears to be a "neoprene like" cone.
Voice coil dust cover is 58mm OD and looks to be of a similar material to the cone but "stiffer"
Large diameter voice coil is clearly visible from the side and it also has quite a "throw", with 200W pumping through it at say 25Hz, it would need to move a lot!
Voice coil appears to be 4 Ohm impedance (DC resistance shows 3.6 Ohm)
Terminations are pretty standard spade connectors with one being thinner than the other (keyed so the speaker is connected in the correct phase)
DIMENSIONS:
158mm x 158mm front frame (edge to edge)
4x mounting holes 4.9mm ID (another 3x holes are present but these were not used in the sub-woofer for mounting)
95mm front to back
Large magnet to the rear, 80mm OD x 25mm thick
WEIGHT: 890g
TESTING:
Just to be sure, once extracted from the cabinet I tested this loudspeaker (working previously fine) both checking the DC resistance of the voice coil and "real live" reproduction of very low frequencies.
DC resistance measurement shows 3.6 Ohm
Using a spare amplifier with a low frequency output that suits direct connection to this loudspeaker, I fired it up - no issues at all.
COSMETIC CONDITION:
USED
Clean
NO damage to the basket, the frame or the cone and surround.
NO "nicks" or cuts to the cone
Both spade terminals are undamaged
I have now placed this loudspeaker face-down onto very stiff cardboard and then sealed within a clear plastic package to ensure it remains unaffected by the environment.
