Will Emotiva be offering another reference series sub? Enquiring minds want to know!

My gut is that’s a tough market to break into. Lots of established players at the price point Emotiva was at and I’m not sure the RS13 at least on paper was enough for people (in large enough quantities) to switch to.
I do think they have found their Sweet spot with the Airmotiv speaker line though. Just my two cents.

I have the RS11 and the build quality is fantastic. It’s a little tank! I think they probably got to expensive t build. Definitely a shame to see the RS series go

I have two RS13. Here is the problem I see and I want to check if anyone can answer my question please.
I placed the sub on the carpet in my basement. Sitting in the front row of I don't see a big difference, from my first floor my wife complains the things are falling off but when I sit in the second row that is two step above the first row in my home theater, I can really see the sub power and it is very good. What am I missing here for the first row.

Where are your subs placed?   Next to the front L/R speakers?  Front and rear of the room, center of the walls?  In the L/R corners?

Based on what you say your front row is in a modal null.  Bass will vary significantly depending on sub position and listening position due to room resonances.  Moving the subs could make a significant difference.

Here are different position I placed:
1. Between LC and CR behind the screen as my screen is perforated. Not impressed.
2. I placed my subs in the L&R corners facing straight, outside my projection screen area not impressed as well.
3. Moved a feet forward not impressed.
4. Tilted about 25 degree towards Center seat in the front row got so much improvement but nothing close to being in the second row.

My next move would be :
1. Put one sub in the front and another in the rear or
2. I am thinking of raising my LCR for about feet high to get the right sound shape to the audience. Currently I have Emotiva T2+ as LCR but since it is not too tall it feels like I have to raise them like feet above, I may use the same formula to raise the height of the sub by constructing a solid wood piece to heighten sub placement.

I am finding it really hard to sub alone in my home. Also next year I am willing to hire a good sound engineer to get the room correction and tuning good. I do not have time nor expertise to get the right sound. I have to find a good one in Atlanta area.

For placement of two subs, Todd Welti's well known study determined that center of the front wall and center of the rear wall are the optimal positions.  That's probably the best you can do for placement of the subs.  

The rest has to do with how they are connected, can they be better aligned to each other in terms of time and levels ... and are you using Dirac or some other room correction.

Marc, Do you think doniv could benefit from stacking the subs and placing them in the center of the back wall? Elevating at least one the subs works might work for him and then there is the co-location effect.

My opinion is to follow Welti's recommendation.  I believe he has peaks and nulls in the response and stacking subs in one location will not solve that problem.  But the rest of the story is all about alignment, polarity, level matching and room correction.   Lots of variables there that haven't been discussed.

Let me look into Todd Welti's information, I found a video in youtube and learn from it. I have RMC-1L and with that I have Dirac room correction can work on with the room correction as well.
