I have a pair of Westra woofers KW-160-1314. Are they any good? I can't find any info anywhere or should I bin them.
seems a defunct company...as a 6 inch woofer likely nothing exceptional... most of the links i found are German.
As I remember they were budget drivers, good for their price but dont expect miracles.
If you look more carefully you can find data on german diy sites:
Westra KW 160 1314
Membrandurchmesser (d) in cm:13,5
Membranfläche (Sd) in cm²:143
Gleichstromwiderstand (Re) in Ohm:3,7
Resonanzfrequenz (fs) in Hz:40
mechanische Güte (Qms):1,651
elektrische Güte (Qes):0,634
gesamte Güte (Qts):0,458
bewegte Masse (Mms) in Gramm:15,04
Aufhängungsnachgiebigkeit (Cms) in mm/N:1,0526
Äquivalentvolumen (Vas) in Liter:30,13
Kraftfaktor (Bxl) in N/A4,7
mechanische Verluste (Rms) in 1,5kg/s:2,29
Kennschalldruck (1W/1m) in dB:85,5
Schwingspuleninduktivität (Le) in mH:0,635
Probably best in 15-20 liter sealed box.
