Hey all,
I am going to be doing a few tweaks to my current 5.2 setup tomorrow, and one of them involves my center speaker. It's a Paradigm CC-390 (v6). For those unfamiliar, it has two big port holes on the rear of the speaker (4 woofers, 2 midrange drivers, and a tweeter). I typically cross it over at 100Hz.
The speaker sits on a speaker stand under my TV, with the back of the speaker about 4" from the wall. I have absolutely no room to move the speaker out any further due to the size of the room and the proximity of the seating positions to the front wall.
I have been noticing some unwanted reverberations and muddled sound in dialogue as of late, which made me experiment with higher crossovers and what I found was that going from 100Hz to 120Hz helped a little, while 150Hz made a significant improvement in cutting out the reverb I have been hearing in certain voices (mainly low, deep voices or when dialogue is being spoken in enclosed environments such as caves or small enclosures).
So my two options are:
1.) Plug both of the rear ports with foam
2.) Raise the crossover to 150Hz (I really want to avoid this scenario due to a few reasons, one being sub localization)
Is it OK to plug the ports? What harm can it cause? Will it change the overall dynamics of the speaker?
