Elusive Bass

I'm having a lot of trouble getting the bass my system is capable of. I'm sure it's the room and placement but no idea on how to fix it. System = Marantz 250 w/3250B Preamp, 2 tables (PL 550 and RP3) with Revel F36's.

I was visiting my uncle who has F35's playing Bowery Electric's "Without Stopping". This is an awesome track for some deep thumping bass. His room is much different and the bass is just awesome but I can't get close to the thump and resonance.

I kinda get the feeling it may be the "holes" in the room. If that's the case I need a lot of something. Loads of bass when standing over the system and in the room behind (image 2) but this is greatly reduced in my listening position. F36's are 16" from wall @ 9' apart. 8' to listening position with 7' behind. Yep, the ceiling is vaulted.

I've downloaded REW which is an open source room acoustics app. A microphone is required but I've been holding out trying to solve the problem without result. I wouldn't post this if it weren't for the room.

Thank you for reading!

Your pics don't show for me.
I'm no expert.
Not seeing room:
If you can move speakers or your sitting position. There are likely standing waves of bass in room. Different locations in room likely see varying amounts of bass. Try moving your chair gradually forward and back. Hear if there is a difference. Room treatments can change bass. Moving speakers closer to walls and corners can add bass. But can get boomy. Most setups are compromises. Depending also on how easily speakers produce bass. Not familiar with yours. How low do they go on spec sheet?. I don't have enough info whether to suggest a subwoofer.

I have a system in a bedroom. Because it's a multipurpose room. I have a comfortable, but easy to move Ikea chair. I can move it, depending.

In another thread on same topic in different forum, OP said he moved speakers closer to front wall and got some bass presence back.

It's important you understand that because the behavior of low frequency reproduction changes in different areas of the room, having a system in a living area is going to be an exercise in compromise if you don't have the latitude to locate speakers and listening spot in optimum locations for best low frequency reproduction. Worst case scenario is "I have a spot to put the speakers and a spot to put the listen chair and that's it"...second worse case scenario is having only one option for either of the two locations (speakers and listening chair). That's just a cold hard fact and one that can be difficult or impossible to correct with only a few basic acoustic treatments, EQ or DSP.

Pretty sure he means 7' behind listening spot to wall....which puts him almost in the middle of the room. He's in a null.

Oh yeah....I read that better and that makes sense. I'm similar in that either pair of speakers I use are about 8 to 10" from back wall, about 9 or 10 feet to center of each speaker, and I sit about 14 feet back. Room is 15 x 28 roughly and is open behind my listening spot. The room layout is nicer when it's like this but the bass response suffers versus having them on the long wall and being about 12 feet from them going the other way. Ahh...the fun of the "room above a 3 car garage". lol
 
Not seeing the pictures either?
OP mentioned another room and not feeling the bass thump. Could it be that the bass is just not pressurizing the room he is in cause the combined area of the multiple rooms is too large and not sealed enough to feel any umph?
If possible, could a door be installed between the two areas that would close and seal off the listening room? Maybe that would help the bass thump?
Actually wouldnt you need a closed off area to help with bass thump in most cases? Ie pressurize/depressurize the room? I would think it would take an awful lot of subwoofers and power to feel bass in an open area?
