More of these things have surfaced from the chaos now.


SH601

This is the same thing as the one named "3-Way 2nd order" in reply #4 above, but the PCB of these ones also has a logo and number on it. The coils are glued to the board with hot glue.

For the benefit of Mr Google, the label on the PCB is CROWN CN330.

16 Available

Also R100 each

SH614



Schematic



Funky! Looks like it was either dunked in the sea or spent time in Durban en route to civilisation, but the useful bits are intact. This one has iron dust bobbins in stead of plastic, and tapped inductors, made to be somewhat configurable. The DCR is nice and low this way and the bobbins are only half full.

The bobbins are held to the board with what seem to be ordinary galvanised steel bolts, which is probably not ideal. With these bobbins present the bolts hardly affect the inductance but you might expect the bolts to saturate and create distortion in use. They should be replaced with 4mm Nylon bolts or carefully tightened cable ties (the bobbins are much more brittle than plastic will be...)

Other labels on this one: EST-BC3014 on PCB; Box is labelled Marksonic DM-C-614

SL-MB-1204



Schematic



It's a 2 way 2nd order with white plastic bobbins that are wound quite full.

The bobbin id seems to be fractionally too small for the ferrite cores from SH601 or SH616 to fit inside them easily.

1 x 370uH 0.6 Ohm
1 x 560uH 0.8 Ohm

SL-BT-1303



Schematic



Mounted on a plastic terminal plate with spring-loaded wire clamps. Woofer does full range, mid has a series resistor and first order high pass filter. Tweeter has a series resistor and 2nd order high pass. The 3.3uF 250V cap on this one is a useful and decent quality Polyester.

1 x 3.3uF 250V Polyester capacitor
1 x 300uH 0.55 Ohm

All types except the first two (SH604 & SH607) are still available.
