improving bass performance in somewhat large room
Hello, I've read a lot of these threads and decided to post because I couldn't find one that matched my parameters closely enough. I'm wanting to improve the bass performance of my HT (half movies, half gaming). Anthem MRX 310 with an Emotiva XPA-5 amplifying Aperion Verus Grand LCRs and surrounds, and a Bravus 10D sub in a ~4000+ cubic foot room (20'x16' with a vaulted ceiling that reaches to 15' in the center). The room has three door openings (two of which have heavy curtains), wood paneling, a bunch of furniture with a large ottoman, and a very large area rug over a hardwood floor.
The main thing I'm looking for is to add some focused impact to the sounds. I'd also like explosions to feel better, but I'm looking for things like the impact of a boulder falling onto some rock and splitting open, a heavy tomb door being dragged open, even things like car door slams or superhero punches. Maybe this is mid-bass? Right now I'm not getting as much of that as I feel at friends' houses. Every time I run ARC, my sub's dB are tuned lower significantly by equalization, which initially made me think it was already powerful enough for this size room. After all, if I set the sub to less than halfway on its volume dial and room correction is reducing it even further, that made me think it had enough juice. To position it, I did both the crawl test, and also ran quick measure to help reposition the Bravus until it had the response curve in the attached image, which also shows the correction results.
I reduced the crossovers for the large towers to 40Hz and the center to 60Hz, which improved the tactile feel I'm looking for, but not enough. After reading these threads, it's making me think that the Bravus isn't enough for the mid-bass I'm looking for, and adding a second one wouldn't fix the problem. Plus I know I should be running the LCRs higher anyway, and probably with matched crossovers.
So, I'm considering getting a HSU VTF-15H MK2. I typically listen at -10dB to -20dB (which from reading the Anthem owner's threads makes me think it's equivalent to 0dB to -10dB on most receivers after ARC is run, so if that's true, I often listen at reference or 5-10dB below reference). I don't care about having a deafening sound, nor do I want something that collapses my house. I just want to feel strong, tight bass when substantial things happen on-screen. Size is no object, but good price-to-performance ratio is important, and I can probably go up to about $1000 since I'll be selling my Bravus after this. I currently don't have the time or inclination to dive into DIY. Would the VTF-15H MK2 be reasonable for my application? Is it overkill? I'd be fine going down to the VTF-3 MK5 instead if there's no point in going bigger.
I appreciate any help!
