Great product. Two fitted perfectly into my 22 year old Kenwood SW-900 woofer unit, replacing somewhat inferior lower rated originals and fully restoring the units' capability.
Only complaint was that the push on spade connector terminals are positioned upwards towards the cone which makes it awkward to connect the wires and also fouled the mounting hole edges of the box with the wires connected. The spades also sit very close to the speaker frame in this position which I wasn't happy with.
I ended up soldering the wires directly to the terminals where the voice coil wires come through so ignoring the spades. The spades should be downward facing towards the magnet which would make connection easier, and I'm sure that's how they are meant to be.
Other than that I am well pleased and at such a great price.
