I’ve got a HSU VTF-3 MK4. I’m sure it's a great sub, but I feel I'm not getting enough bass out of it, so I probably have something set wrong. I’m running maximum extension mode (one port plugged) with the Q set to 7. I ran Audyssey on it with the volume knob set to 9:00. Audyssey set my amp sub volume to – 4.5 db. Those settings gave me weak bass.
I had to turn the sub volume knob to about 10:00 or 10:30 and the amp sub volume to +3 before I was getting enough bass to make me slightly satisfied. It still wasn’t knocking my socks off.
I ran the 20hz test on the HSU sub CD. It made my doors rattle a little, and my head feel slightly weird due to the pressure…cool stuff to demo for friends, but when I would put on a movie like the Matrix, I still wasn’t completely impressed.
My room is a basement, with a concrete floor covered about 70% with a bunch of area rugs. The room is about 25x17’ with a 6.5’ ceiling. My sub is against the wall, 3 inches away, with the ports firing towards the wall. I bought a GRAMMA and set the sub on that. Due to logistics, I can’t put the sub against or next to the couch (the couch sits towards the middle of the room (about 2/3 of way, with the sub about 5 feet behind it). I did a sub crawl and found a particular spot on the wall that seemed to product better bass, so I moved it there. Still, it’s not knocking my socks off.
I definitely get a different feeling out of it depending on the source material. (I understand that source material obviously has a big impact, but I’m trying to find some settings that would be good all-round for all situations. I have a Denon AVR-1712. TV is watched through a TV connected via HDMI. Movies and games are through a PS3 connected with HDMI. Music is streamed through Samsung Smart TV app, through the optical cable to the amp.
- When I watch TV (through a Tivo connected via an optical cable), I feel like I barely ever hear any bass.
- When I play a racing video game, I get a good amount of constant bass.
- When I watch a movie, I get good bass sometimes, but I need to crank the overall volume on the amp.
- When I listen to music, the bass is there, but it’s not tight and there is no punch in the chest.
What could I be doing wrong?
