Budget subs like the F12 have a tendency to over-emphasize frequencies to increase the "wow" factor, making them seem more powerful then they actually are, so what you're hearing is often embellished and not accurate. The HSU will also be more faithful to the fundamental note, and rely less upon harmonic distortion, which could make it sound less impressive sometimes.
What do you have the phase and subwoofers gain set at? How about the sub out level on the AVR? Did you get a chance to run the room correction yet?
I think I prefer the wow factor and being embellished. stf2 is going back. I am not paying $400 for less bass.This is going to be a novel but I am letting out frustration so sorry. I am really screwed now. The F12 sounded fine but the stf2 was just ok. Then I ran the Yamaha Ypao (junk). Actually I have run it 4 times. First 3 with both subs and once with just the stf2.
First time with both subs phase at 0 and gain in the middle. Result: Front and surround speakers large, volume -8.5, crossover 110. Figured the volume was too low.
Second time with both subs phase 0 and gain at 1/3. Result Front and surrounds large, volume -3.5, crossover 110. Trying to get volume at 0. Right? This was close enough for me. Didnt sound too bad really. Set the front and surrounds to small, lowered crossover to 80 and set volume at 0. Then I get very little bass even with my ear on the subs. AVR menu and I change setting to "no subwoofer". It automatically changes my fronts to large and I get more bass. Now I am getting more bass from my fronts than I am 2 subs worth $600.
Run Ypao 3rd time. Same setup as first time. Phase 0 and gain in the middle. I figure if I can get the AVR volume back to -8.5 maybe I can turn up the volume on AVR and actually get some bass. Same results with AVR. Fronts and surround large, volume -8.5 and crossover at 110. Set fronts and surrounds to small, crossover to 80 and turn the volume up to +10. Very little bass. Turn up gain on the subs to 7/8 and get some bass but of course mostly distortion. This is with subs and receiver maxed out. What happened to chest thumping and walls rattling. I can barely even hear it. It sounded much better the way I had it with just the F12.
Run Ypao last time. F12 is OFF.I am hoping that running both of the subs is confusing the receiver or something. stf2 phase 0 and gain at middle. Crossover OUT by the way. Same exact result as when I used them both. F and Sur to large, -8.5 volume and crossover 110. Set F and sur to small, crossover to 80 and volume to +10. Still get more bass from my fronts than I do the sub. I have to max out the sub and receiver volume to get much of anything audible from the sub. It was better before I started screwing with the Ypao and now I cant get back to where I started. At this point I might as well not even have a sub and I have 2 of them in a small room. Unbelievable! Now I have been messing with it all day and half the night and I am going out of town today and its gonna bother me the whole damn time.
