4 terminal speakers / Bi wiring

[The Merovingian]

Looking to replace my existing 4" speakers (MB Quart) which has failed but struggling to source a suitable 4 terminal speaker can anybody recommend a decent brand

What is the current model?

Are you talking about a speaker that allows Bi-amping.

As in, one pair of stereo channels is fed to the tweeters and one pair to the mid bass?
