Quick update -
Took delivery of the first set of speakers I ordered: two OMD-5 for front channels, OMD-C1 center channel and a Prestige S10 subwoofer. Outer boxes were a little beat up but intact. Factory boxes were fine. Everything sealed and new, as advertised.
The OMD-5s were factory perfect. The OMD-C1 had a small mark, about an inch long, on the cloth grill. You'd have to look carefully to see it. I'll just mount the grill so that the mark is in the back. No problem. The speaker itself looks great.
The subwoofer, however, was damaged. the unit has two rear-firing ports. One of them had come loose and the cylinder was just rattling around in the enclosure. I also didn't see the isolation feet included but frankly when I saw the damage. I just packed the unit back into it's factory box.
I contacted Vann's the following day. Customer service was helpful. They will schedule UPS to pick-up the faulty speaker in order to make an exchange. I don't know yet if they are going to do a cross-transfer. I had to delay the pick-up because I am unavailable until later in the week. I hope to have it completely scheduled with Vann's tomorrow.
In the meantime, this "second' sub will be coming in next week, so I'll be fine.
I'm "breaking in" as I type. I'm basically just running them in all channel stereo at low to moderate volume. When I am not watching TV I basically just tune in to music channels.
So far so good. Speakers sound sweet to me.
Right now, I have the center channel sitting on a TV bench, so it's blocking the bottom of the TV screen at the moment. I'm planning on mounting the C1 upside down from a shelf that is installed above the TV screen.
Quick question - I know the included mount works to mount on vertical surfaces. Has anyone used it to mount upside down (e.g., from a ceiling) or do people think that a separate, stronger mount is in order for mounting upside down.
