Yea, we're not trying to squash discussion so much as we're trying to let them know that they can't simply abuse us and have their links all over the site without some consideration for other companies who actually pay us to advertise here.
At one point one of their emplyees was posting links all over in reponse to questions. We went into discussions about advertising with them and they declined, feeling that they simply didn't have the budget for even a very small token amount for the forums.
Now, this was the equivalent of about 1/10th what our
smallest advertiser pays, mind you - so you can see where we might be a little reticent about allowing them to get linked up here.
Here is just one other resource for loudspeaker parts & kits:
