with tax returns coming I don't know what to do. guess I'll hold off a bit and see what Emptek is up to?

It is insane what I was missing before with my old garbage sub.

Haha yeah that scene is nice, though fairly short. Still a good movie though! Iron man...3 I think...where the guy comes to his house in the chopper. OMG. I can feel the pressure waves going from front to back of the room. The e1010i's handle it with poise too. Definitely not sloppy and I don't hear port noise ever. Extremely surprised with what they have for this price of sub. Obviously no XS30 though lol..

I have a similar room to this. Is that the large center on the mantel? If so is it just sitting on there? How wide its the mantel and how far is the speaker from the wall?
Thanks in advance for your input as this will help me make some decisions.

I've seen some pretty wide mantels before so there's plenty of room for an E56co to sit.
with the tv up high does it at all cause any discomfort issues during long periods? my old apt tv sat high like that and it use to give me headaches looking up all the time.

My neck hurts just looking at it...
post #2826 of 3149

I've got my TV mounted fairly high up above my fireplace as well with no neck issues. It all depends on how close you are to the set.

Got my E56Ci on thursday, man it is BIG! I spent the better part of last night wall-mounting my TV, the piece of crap stud finder from Lowes left me with some spackle work... Got the TV all mounted though, and now I just need an angled HDMI adapter and a wire channel. Didn't get around to hooking up the center last night, but it's the first thing I will do after work today, also need to re-run Audyssey. I will take some pictures this evening, but it's safe to say I need to a bigger TV... my 42" plasma looks mighty small hanging on the wall rolleyes.gif

Nice! Where are you placing the center?

Here is a shot I took last night. I mounted the TV slightly higher so that when I drop in a nice 60" it will be just right wink.gif

Are you opposed to running the wires through the wall?

I live in an apartment so that isn't an option unfortunately.

Makes sense. The easy cheat is hanging the new tv a touch above the center.

 

I finally hung and drilled last week, I'll share a few pics.

Yeah that is a good point. I strategically have this ready for a 60" plasma, just need to find an extra $800... rolleyes.gif

Looking forward to seeing your setup!

I've been lurking on here for a while, posted a couple weeks ago asking for recommendations. I settled on a set of Empteks (55ti, 56ci, 55wi) to replace my Fluance SX-HTBs. The fedex dude should come knocking any minute today with 180lbs of happiness - will post pics after!

Sounds like a great Friday!

 

I'm killing time trying not to find an external amp to help drive the fronts. I don't like running the receiver at 80%. (I know, I know, it's not a linear relationship.)

We like our speaker porn! Good luck and welcome to the EMPtek family!

My EMP towers eat up something less than a watt of amplifier on average. I've measured as high as 18 watts on peaks. You are nowhere near 80%.

I had to do a double take. This man's system looks very much like mine.

I hear you. My Marantz SR5008 shows volume on a 100pt scale. I'm watching movies and music at 70-80, hence the 80%.

 

We all know the emp's aren't the most efficient of the bunch. What kind of avr are you running?

But it's not a linear relationship. It takes less power to get to 85dB for example, then it does to exceed it. You may be on 80% according to the volume level on the receiver, but you aren't actually using a corresponding amount of power. Reference SPL is 85dB with 20dB of headroom.

It only takes about 8 watts to reach reference (85dB) at 10 feet away with the E55Ti's, however to account for that headroom you would need over 200 watts.
post #2843 of 3149
That is even an overly conservative calculation because it would only be correct for an outdoor system or one in an anechoic chamber. Rooms add quite a bit of gain to the sound presentation. I suspect you could go well past 100 db with less than 100 watts in a real room. If home theaters needed 200 watts per channel, that is what the equipment would have. My receiver, as an example is rated for something around 130 watts per channel and it is THX certified. The difference between 100 watts and 130 watts is one single db.

88dB sensitivity for the E55Ti:

Assume we sit 10' from the speakers, that's about a 10dB loss.

1 watt = 78dB
2 watts = 81dB
4 watts = 84dB
8 watts = 87dB
16 watts = 90dB
32 watts = 93dB
64 watts = 96dB
128 watts = 99dB

You are going to need a substantial receiver to deliver over 120 watts per channel with all channels driven, and that won't get you the 20dB headroom for true reference levels. The average receiver is not designed to deliver reference levels in a theater, that's why people have high efficiency horns and discrete amps to hit those levels. Sure you gain some SPL from the room, but the point of my post was to show the relationship between power and SPL.
post #2845 of 3149
You missed the point. It isn't a 10 db loss at 10 feet. You are using 6 db per meter and that is the anechoic figure. In a real room it is more like a 3 db loss. In my room it is less than 2 db at 11 feet.

+1. The inverse square rule applies to all of the sources. Outdoors, or anechoic, the speaker is the only source, so a drop of 6dB per doubling of distance from it is accurate. Indoors every reflective surface becomes a virtual 'source', so for the inverse square rule to be accurate you'd have to move away from not only the speaker but also all of the room boundaries simultaneously.
post #2847 of 3149
Regardless what the SPL drop from distance in a room is, the relationship between power and SPL is still exponential, that's all I was trying to show.
post #2848 of 3149
I understand that. I was just fighting the belief that someone needs 200 watts per channel to play a movie.

Of course no one needs 200 watts to watch a movie, but you need a good bit of power to make the EMPs hit 100+ dB.
post #2850 of 3149
Less than most people would think.. In my listening room it takes 18 watts.
