Power Sound Audio assembles their ice amps here in the US, and RBH manufacturers their products in the US, whether that includes amps I don't know, but not everything is made in China.

RBH stuff is made in China but much of it is assembled in the USA. I'd suspect all EMP Tek is made in China.

From what I understand, RBH and EMPtek make their own drivers.

Set up #1: EMP e5ti, e5Ci, and EMP e5Bi surrounds, Outlaw LFM1 Plus sub, EMP 10i10i sub
Set up #2: Def Tech SM450, CLR2002, SLS Qline surrounds and Klipsch 12wD sub
Set up #3: Philharmonics- BMR in a 2.0 system, music only

From what I recall...
The aluminum drivers are proprietary and designed in U.S. They are manufactured in China.
The tweeters are usually Vifa or Scan-Speak.
The cabinets are designed in U.S. and built in China.
The finish on Signature speakers is applied in U.S. except for the Black Ash which is also China.
Signature speakers are assembled and tested in the U.S. the others in China.

Thanks!

I got the wiring all done. I now have two dedicated 20amp circuits for my home theater. I should be good to go now!

I'm working 14hr days until this weekend, so I wont be able to make them sing til then, unfortunately.

More input to come, soon!

I have some picture frames in my theater that are pretty well secured...they aren't falling off, however, they rattle when the heavy hitting strikes! last year, Godzilla 2014 took a guiness glass off my shelf and that almost made me cry (the acting in the movie did make me cry...brutal!).

I think it was just the casting, they spent all their money on Cranston and then had to get by with the rest haha.

All I have to say is these subwoofers definitely hit LOW. They seem to actually prefer it. (And I have all 3 ports open.)

Just a small update.

Firstly: This recording is terrible quality... I recorded it with my aged iPhone 4(!), so it doesn't pick up sound, can't auto focus, and overall quality is poor. But then again, it's a YouTube clip so it doesn't really matter.

Still breaking these bad boys in, and the volume is pretty low. Gains only turned up 1/4 the way on the subwoofers, and this was FAR from clipping/max volume. Things can move some air!

Enjoy:

If anyone is interested, Audioholics has a preview article on the RBH I-12 sub on their front page. They also have a link to a youtube video about how the sub measures in the forum thread.

Interesting, they did a review based on RBH/EMP specs and photos!? I assume they are going to do an independant test...

So far I've been watching a lot of TV Series (GoT, True Detective, etc...) and I'm loving the subs for them!

They really hit my chest and shook the foundation during the explosion/shoot-out scene in the most recent TD episode

I am thinking of getting two pairs of R5Bi and a R5Ci (subwoofer to be determined - will probably use an old Sony for a while then get another.) Near 100% use will be for movies and TV.

I am wondering about speaker placement. It is for a small bedroom. I talked with someone at Emp Tek about placing them near walls; he said 3 or 4 inches from a wall is fine for these speakers (just not right against a wall.)

People with these speakers agree that these speakers are fine a few inches away from walls?



Also, will Audyssey MultiEQ XT correct for this and/or will this be a problem for backported speakers in general in my set-up: My center will be about 6-8 inches from a wall, as well as my front right speaker, but the front left speaker will be about 2 feet from the wall (walls are deeper into room where it will be placed.) Will the center and front right being closer to wall than the front left be okay for the Emp Tek's or should I resign myself to only looking at sealed or front ported speakers like the Wave Crest HVL-1s because of this situation?

What shape is your room? And is there any way you can set up your system at a place where each side will be roughly the same? Typically in a rectangular room, placing your speakers on one of the short walls is the best. The reasons are your L/R speakers will have the same wall distance on each side of them, you will be far from the back wall where reflections are a problem, and you have the ability to move your system or your seats forward and back to find the best spot for bass.

What Audyssey will do is put the level of the speaker closer to boundaries at a negative level to compensate for the boundary gain it will get. It will help, but it will never be quite as good as described above.

Another thing to consider:

If you're crossing them at 80Hz to a sub, the ports won't be moving much if any air so I wouldn't worry about wall distance for that reason. But you'll still have SBIR to think about.

I need the TV on the wall where it is located - no choice with layout of room (the bed needs to occupy the only straight wall.) Other walls have various things making them have variations along their walls: window alcove, sloping ceiling corresponding with house roof, bathroom and closet doors and the wall where the TV is located has a different layout in wall recesses. For example, to the right of the TV is the bedroom door and the wall directly to left and right of door comes further into the room where an air intake shaft for the A/C is located on side and the other wide has an air duct shaft, pushing the wall into the room about 1.5 feet each. Then at the TV to its left, the wall is normal and therefore about 1.5 feet further back than those two wall shafts.

There is nothing I can do about increasing distance behind the center speaker. I could move both left and right speakers right next to the TV, to have equal space behind both but then they would be right next to the TV (about 4 feet apart between left and right speaker in that case) which probably would not sound as good as being 8-9 feet apart as they would be positioned now and would preclude me from getting a larger screen TV in the future which I plan to do (I have a 42 inch now and could easily fit a 50-55 inch TV as-is but if speakers were right next to it, that would push the front right speaker right in front of bedroom door even if I moved the TV a little to left therefore not possible.)


Also, I do plan to do a crossover at lowest 80 Hz, and I might even do 90-100 depending on how well the Emp Teks handle 80-100 Hz area. So as you wrote in another reply, at 80 Hz or higher, the difference in wall distance should not be much of factor?

That is interesting (echo waves canceling out waves causing various frequency holes and amplifications.) AS far as my set-up, nothing I can really do about speaker placement (LCR will be different distances from wall.)

Since this is mainly low range, As far as my set-up, with a 80Hz crossover or higher, should the different wall distances, as described above, play a major issue?

Should I rule out back ported speakers? I like what I have read about the Emp Teks but if front ported would be better for my case, I should probably get the Wave Crest HVL-1s (they would cost less.)

I wouldn't worry about differing distances to the wall behind too much. I hope I'm not confusing you with the SBIR thing - it's a good read for anyone, though.

I would stick with the plan of putting the L/R further apart. Ideally you want an equilateral triangle; if you're 7 feet from them, they should be about 7 feet apart and angled in slightly. In my space, the best I can do is 8 feet apart and 9-10 feet from my ears. It's okay if it isn't perfect.

I wouldn't worry about the ports unless you run them as "large" without a sub.

Thanks for helping me. I enjoyed that read - I like to understand things instead of just do them (but I could see how trying to manage the SBIR issue would be a big undertaking if you seriously tried to tackle it - my room has so many variations on walls, it would likely never be solved.)

My left and right are about 9 feet and that is also roughly my distance from each speaker, so it would be 60 degree arcs at me, and the left and right speakers forming a perfect triangle between the three.

If the calibration sets them as large, Ill changed them to small and make sure the crossover is at least 80Hz or higher.

I will say I am LOVING these EMP Towers! The midrange on them is freaking amazing. I could never go back. And people saying the high-end/tweeter is a bit lacking due to the forward midrange, I'd have to disagree. Maybe it's because I have concrete walls in my basement, but the brightness on the EMPs is perfect and very detailed.

I'm actually amazed on how good these speakers are for the price I paid for them.
