Switches setting for M5-HP with the 2WQ at 80Hz

send an email to the mfgr cust serv dept.

I already left 3 voice messages and 3 emails on Vandersteen web sites about 3 weeks ago to ask the instruction. There is no response. That's why, I am asking a help from this forum.

I guess they started printing the settings right on the crossover cover sometime after yours were made.

There's no 80K setting on mine, but there is a 50 and a 100.

Assuming that they have not changed the switch settings*:

For 50K, set 1, 3, 5, 7, 10

For 100K, set none

Try both. One will likely be clearly better.

* +1 on checking with Vandersteen!
