To be honest I have to live within my means here anyway - I've only got so much cash for audio upgrades saved up, so the IB is definitely a 2009 project. I need to buy a ride-on lawnmower and snow blower this year too. And about $4000 of sod. :sad:
And I suspect we'll to do something about my wife's car situation in the fall - she's been without one for a year now.

:lol: I feel sooooo sorry for you guys and your WAF. Must suck.
Mr. P, thanks. I think I'm going to stop in that Kellum's store and price them out. BTW, I paid $80 for my Monster HDMI cable, the one below their fastest speed. I've never paid that much for any type of cable and I'll never do it again.
Guys, something a couple of my engineers here brought up: the LPA-1 will draw about 13 amps. Probably not continuous, but should I try to keep this at least plugged into a separate outlet, even though the socket may be on the same circuit as the rest of the A/V equipment?

I would do it if you can, certainly wouldn't hurt anything.

That's for sure! I'm having trouble getting my toes to un-curl today.

Oh its there...and it manifests itself when you least expect it too. The whole idea of building the HT room was to avoid WAF and give her her living room back. So far so good - but she's starting to offer "advice" on things like "color" and layout...

Man, you guys so easily slide right into the gutter ya know? :rolleyes:
If this thread starts mimicking the Rep points thread, you won't be able to blame me! :p

Kinda what we got going on right now. In a way, our living room is my dedicated room. Our front room, I usually refer to it as up front, is hers and she does whatever the heck she wants up there. The back room is mine. She'd kill me if I touched anything in the front and she doesn't bother me for having 14 panels, 15"sub, 7 large speakers in the back. No complaints about my other 2 systems either. I think I got it pretty good. Alot better than those guys posting on here saying my wife won't let me have towers or a big sub.

I've just operated on the premise that it's easier to beg forgiveness than to ask permission...so far so good.

L.J., have you updated your gallery with more recent pictures of your panels? Last time I looked, I don't think there were 14 ( :yikes: ) panels in your room. And did you also use the wood frame method Kex and others used when you built them?

No I need to update the pics. I've added more panels and put up blackout curtains. I still need to add some more curtains and tint a couple of more windows. I use to have them covered with foil....but you couldn't see it because the blinds were closed all the time.
I glued my panels to a 1/4 inch board and wrapped them with burlap. The corners got smashed a bit but it doesn't look bad since each panel looks exactly the same. I also purchased some made panels and mine look exactly like the premade ones. I have 7 24x48 & 7 24x24. I ordered all my diamonds premade because I just didn't feel like bothering with cutting stuff and all that mess. The premade panels have a wooden back on them and a frame around the edge. The echo I had in the room is gone so I'm happy with the results.
Kex, is there any benefit to having a open back on the panels when flat against the wall? I was reading on this but it was saying that the panels needed to be off the wall a bit (12 inches I think) to get any benefit from a open back. Something about the sound going through the panel twice.

No advantage to open back. No disadvantage either. Whether a board or a wall is back there, it's a hard, reflective surface.
There is an advantage to placing the panels a few inches out from the walls, even 2 or 3 inches will allow space for some more absorption. I've seen 4 inches recommended a lot for better bass absorption, and another rule of thumb is a space as thick as the panel itself, don't know how scientific that is though.
But to be honest, that's getting in over our heads. For echo and flutter, and taming reflections, flush mounting is fine - the space in the back allows for more diffraction and slightly better absorption of lower frequencies. So for taming echoes, it's not a big deal for us. And that's really what we're using it for in home theater moslty. I don't have the equipment to run a waterfall plot of my room's acoustics and aggresively attempt to pick off bass peaks one frequency at a time by calculating air gaps behind optimally placed panels. That's for sound/recording engineers in studios and space shuttles. For us, the amateur DIY HT hobbyists, placing them on the wall at reflection points will accomplish most of the desired benefit.
But you've probably figured out now that for bass traps, that's why its recommended to place panels across the corners to truncate them rather than run panels flush along walls in a corner - so if you have corner traps, you are taking advantage using that air space to increase absorption.

Which brings us to... Q factor! :ihih:
The way I understand it, Q factor is the point where a room's resonant frequency is matched by the audio output's frequency, which causes an amplitude spike, correct?

I thought that was a node.

amen to that, i think the only way my speakers could be uglier is if they were orange.
what's a BFD do anyway?

You can adjust the Q factor within your Paramentric EQ setup on your receiver. FWIW. :idea:

I could be wrong, but I believe that the Q factor is this. When you boost a particular frequency, it affects the frequencies around it. The Q controls how far on either side of it that it effects, and also the slope away from it.

Errr...ummm....yeah, that's actually not a bad way to think of it.
Q is used a few times over in different parts of audio. It's just a ratio that effects the quality of various graphical curves. For the BFD and parametric equalizers, it's just how wide a "range" each filter adjustment has on either side of the target frequency.
So yeah, what GM said.

Nice job GM. Thanks! :thumbsup:

C'mon Kex, she's been without a car for a year now, she's getting used to it, let her know you have your priorities. Give her a bus pass for Mother's Day.
Rich, $80.00 is about where high quality cables start. Get with the program man! Really though after getting a better amp try a pair of the Tributaries in place of your current speaker cable to see if you can tell a difference. If you can't you shouldn't spend the money. On the other hand why spend big money on speakers and amps to cheap out on cables, at least see if there's an improvement.

Cool, thanks. I got one right. That makes it 1:37,899,243 now.

$80 is what I spent on the HDMI cable, and some might say (check back on post #7 where Kex found a bad Monster cable), that Monster isn't the epitome of high quality. As far as my speaker cables, I'm very happy with them. They're 12 gauge Sound King OFC rope cables that were a breeze to work with and terminated with GLS Audio banana plugs. What I'm actually asking for suggestions on are IC's from the receiver pre-outs to the amp. The only cables I have along those lines are scrawny little dual RCA's that are very old and in most cases too long. I think I saw those type of cables at Kellums, but my next stop is Blue Jeans. Thanks.

The signals present at the receiver's pre-outs are line level analog, correct?

It has arrived
Somehow I managed to get it out of the box and onto the island in the kitchen for the photo-op, but at this time I have no strength left to push the button on the camera.
The manual says the shelf it sits on will need to support 75 labs, and they ain't kidding! The purchase and shipping process went like a breeze, but getting this beast located and set up is going to be no easy feat.
Unless it's normal for electronics products like this to not be UL listed, I'm going to get in touch with Emotiva (or ask on the Emotiva forum) to find out why it's not.
Irregardless, I'm sooooo looking forward to clearing out the loser neighbors surrounding me, with their unkept lawns, sloppy kids and whiney little pisant lap dogs for some people who know how to appreciate +120 dB of Metallica! That's right!!! :23:
