I've been using this speaker for my center channel driven by Yammy receiver and it performs very well. I've got this used and traded my lightstand and umbrella to get this. My concern is that I can't remove the grill to thoroughly clean the driver. Does anybody know how to remove the grill? Manuals are available on the web but it cost $9 to download it. This coaxial speaker was released on 1982 and the driver is shielded for HT use. Somebody told me that this was very expensive when first released by Pioneer.
