First question.
Is it ok to flush wall mount rear ported bookshelf/center speakers, if you plug the rear port and use a crossover setting of 80-100 hz? I would be using a decent subwoofer in the setup.

Second question.
I was thinking of utilizing Energy veritas mini - c center speakers as my front LCR speakers. But since there is no mounting holes, would I ruin the speaker sonically by putting to small screws in the back to mount a keyhole fastener such as these at Lowes?

Displays are like 100% cotton t-shirts. Always buy a size larger than you think you'll need, as they tend to shrink over time.

About mounting a rear ported speaker on a wall. The general rule of thumb is keep the same distance or more from the speaker to the wall as the diameter of the port. Some ported speakers have rubber stand offs to ensure that you keep the proper distance as to not restrict the port. You can try plugging the port but you may not need to.

I don't know if you would ruin the speaker or not.... But you could use 3 of those as LCR's but I would mount the L&R vertically not horizontally. A horizontally aranged speaker is a compromised design. The best is 3 identical LCR's all mounted vertically.

Thanks for the quick response. I was thinking about the Energy Verias v-mini-c as LCR, the center horizontaly under the display, and the L & R, vertically on each side.

Problem is that I only have 6.25-6.50 inches depth to work with, before the speakers stick out beyounf the front of the display. Since we view the display from varying angles, I wouldn't want protrusion.

Maybe. If you had all of the driver Theile-Small specs and modeled the speaker with modeling software you could accurately predict the result of blocking the ports. If you had measurement gear you could block them and measure the results. But otherwise it's a shot in the dark.

Could you explain your layout and setup? Like is there an entertainment center or is TV on a stand, or is it wall mounted? Pictures of your room would be really helpful or even a drawing.

How wide is your front wall? I'm asking because some ppl like the look of LCR's as you described with 1 horizontally mounted below the display as the center then the L&R vertically very close to the sides of the TV. I'm thinking you should keep your front speakers wider than that if that is what you were thinking. Ideally you want to make an equalatteral triangle from the L&R speakers to the Main Listening Position. So if you sit 10' away your speakers should be 10' apart.

A simple "I have no idea" would have sufficed.
