I'm assuming it's because those sub's fell on their face under 25hz, so it didn't bother them since they basically had zero output at those frequencies.

As each day passes by I fall in love with this subwoofer more and more. Now I've got a difficult decision coming up, upgrade my TV or add a second VTF-3 MK5? My current TV is an LG 50" plasma that has served me well for almost 8yrs now. But now that I've got the home theater bug, I'd like to get myself a new, larger TV. But I'm also an extreme basshead, so I'm at odds with myself lol.
Definitely a second sub can help in giving you more clean headroom and it can help smooth out the response if placed well. Though given your previous settings stated, the sub seems to be good, so a new TV would be a pretty nice addition.

I ordered a second VTF-3 MK5 from you on Tuesday Scheduled to arrive early next week, can't wait to hear/feel what two of them sound like! Should also help alleviate some of the peaks I'm experiencing with the single 15. That was the only thing I miss from my previous dual BIC F12 set-up, which was smoother throughout my living room. Now with the second 15 on the way I should have that same smoothness, but with the added benefit of crazy output levels

You made a good choice with the second sub over a new TV. I just "upgraded" my 9 yr old 50 in Panasonic plasma (that had lots of image burn-in at the bottom of the screen) for a 60 in Samsung 1080p (under $500 on sale at Costco) and am satisfied, although the plasma had a better picture (blacker blacks), better off-center viewing, and it kept the house warm in the winter, but your eyes get used to the new picture. I'm not ready for the 4k sticker shock. Of course I'm jealous of your subs as I am still using my pair of HRSW10 cylinders.

Can you tell us in detail the improvements you hear after adding the 2nd subwoofer? I'm currently in a similar situation as you where I'm strongly considering adding a 2nd VTF3 MK5HP. Also, let me know what settings you're using, what your listening levels/habits are, and what your room is like. Thanks.

Will do, it should be arriving early next week, so excited!

Balanced XLR subouts are more commonly found on higher end receivers/surround processors, so they would likely have descrete sub preouts that allow you to adjust distance, etc. Even if it is just split internally, you can still split the signal multiple times.
On a related note, can you tell me what happens to the voltage of a subwoofer pre-out when you use a y-splitter? Say you connect an RCA y-splitter to a subwoofer pre-out that's hypothetically outputting 1.3 volts of clean, undistorted, & unclipped line-level analog signal. What happens to the voltage of each line when it gets split? Does it stay at 1.3V for each? Does it attenuate? Sorry, this is more of a general subwoofer/preamp question rather than a HSU specific question.

I ordered a VTF-15H MK2 first real home theater sub, currently have an 8" on my PC but going from built in TV speakers.

Good question! Since our sub's low level inputs have a high input impedance, y-splitting the sub pre-out has negligible effect on the output voltage. So if you y-split an output of 1.3v, it would likely be somewhere around 1.29something volts or so. So you can y-split multiple times without a perceived change in output. Another thing to consider is that when using two subs, you can get upwards to 6 dB increase in output anyway, so it will be even less noticeable.

My second VTF-3 MK5 arrived yesterday, and I got everything set-up and re-calibrated last night. Boy am I impressed! Obviously I picked up more output overall, but the biggest difference is how much smoother the bass is. I no longer have any extreme peaks in the response, everything is much smoother. Also the quality of the bass sounds better, and zero localization now. Also since I gained output, I don't think I will feel the need to run both ports open for the extra output, instead being able to leave them in max extension mode.

Overall the second 15 was a tremendous improvement, mainly in the all around quality of the bass. I have both subs gain set around 10 o'clock, one port plugged, EQ1, Q at .5. I typically listen around -10db when listening "loud", and every now and then will get close to reference for small bursts. The only problem now is that with sub 20hz content it sounds and feels like my house is going to fall apart lol.

Very, VERY impressed. Don't see myself changing anything in the subwoofer department for awhile now, completely satisfied.

Well, that's all the confirmation I need. I'm now following your footsteps and ordering my 2nd VTF-3 MK5 HP. But wow, your volume dial on both the subs are 10 o'clock? You might want to get your house frames reinforced with steel. LOL!!! That's pretty loud. I got mine at around 9 o'clock and I don't think it's too little.

Yup 10 o'clock, but I'll admit I'm a basshead lol. When watching movies I want to have the maximum output I can get, which is why I run them so hot. Keep in mind I RARELY reach reference volume, typically maxing around -10db give or take 2db. That is another reason why I have the gain a little high, to make up the difference.

I'd rather turn them down with the AVR trim if they are too loud, than have to raise the trim really high to satisfy my bass craving.

FWIW when I ran the audyssey calibration, I had the gain a hair above 9 o'clock and it set the sub trim at -8db. Since I like my bass hot, I then raised the gain to 10 o'clock. Any tweaking from there is done with the sub trim on the AVR.

The second sub will not disappoint. Be prepared for a large increase in bass quality, so much so it took me by surprise. I'm very excited for you!

Thanks, I'm getting excited just reading about your experience. About the trims, though. Audyssey put your trim at -8dB? Did you consider just cranking the trims higher to 0dB or something like that to increase output? Or did you do that and then also crank up the dial in the subwoofer back to 10 o'clock?

No, after calibration was finished which set the AVR sub trim to -8db, I then bumped up the gain from 9 to 10 o'clock. And now I occasionally adjust the sub volume buy raising or lowering the sub trim, never touching the gain again.
