Sir, it's like you read my mind and knew exactly what was going on haha!
I actually just got off the phone with an HSU agent and he was super nice. He gave me the expected availability of the VTF-2 MK5 and it is not bad at all. But after I explained to him my room situation, he was suggesting that 1 good sub would probably do the job for my specific room layout. I don't have the specific measurements of my living room yet, since I am not moving in until July 3rd. But attached are the pictures for your reference. Basically, my room has an open floor plan in rectangular shape. So, the room is not big (small even), and viewing position is skewed to the left near the yard door, leaving an uneven open space to the right of the seating area. The distance between the viewing seat and the TV isn't long either (less than 14 ft?), so there are basically walls in the front, to the left, and also behind the couch (I will try to push the couch forward a bit for better surround sounds). In general, the layout is a bit weird, because there is an open space to the right of the viewing area that connects to the kitchen.
Long story short, the HSU guy was recommending that maybe 1 good sub in the left corner would do the trick, and maybe try to lay it on top of the foam pad or something to try and reduce the bass transmission over the wall into the neighbors - if I get any complaints. Though, he said, it still will be tough to say whether that would help, and I may need to do more customized EQ to strategically roll off the low end.
And like you said, he did tell me that the USL-15 actually has a smaller footprint (18' square) than the VTF-2. So I am now thinking that it might be a good idea to just get one ULS-15 and position it in a way that works with my "weird" space haha! Maybe in the future, when I can afford a bigger and disconnected home, I will add on another ULS-15 sub.
What do you think? Does this sound like a good idea? If I decide to go with 1 good and clean 15'' sub, is the ULS-15 one of the best value option here? Or should I look into something else?
Lastly, thanks so much for bearing with me! I am a music enthusiast who enjoys making music, however, when it comes to home theater audio system, I feel like a noob with lack of knowledge, and naturally anything Hifi audio can be extremely overwhelming for beginners to learn. So I really appreciate everyone's patience and support here
