Anyone that has been following, will know that I am working on tweaking and aligning my new system consisting of Dual drive ULS15 and my Paradigm Studio setup. I do plan on a full review and accounting later but here is something I found amusing.

My first day playing with the news subs was Saturday, the HSU has such a clean and powerful sound and when paired with the Paradigm, gives a result that is hard for me to describe but I will try a few words; Pure, Dynamic, enveloping, absorbing .. get the picture?

Anyway, I was mucking about for about 4 hours playing various music and crawling around in the basement looking for the sweet spots for the subwoofers. The Wife calls me, " the tv isn't working". So that doesn't make a lot of sense to me as the Internet and the phone are still working and both are supplied by the same cable so something else must be wrong, call the cable guy. All good, appointment made for Monday morning.
After the entire weekend of shifting and recalibrating in the theater, on Sunday evening, I call my daughter down to show here where the cable hookups are in the service area of the basement. I needed her to be able to aid the repair guy as I would be at work on Monday and it would be a sin to withhold discovery channel from the wife for a 3rd day!

WELL LOW AND BEHOLD... I am looking at the Amplifier for the tv signal and the light is out. I follow the cord to the 110 supply and it was unplugged!! I pushed the plug back into the wall the TV's all started working!!

Short version, These subs are so powerful that the plug came out of the receptacle in a cement wall. This plug has been there for years! The environment has always been subject to my home theater, and it was no slouch.

This is just "Better"

You may need some LocTite for that plug
Thanks for sharing, BZB

Habit forming, that is what the ULS-15s are, habit forming.

While it is true that experimenting with the subwoofer phase settings to achieve maximum output is useful in some setups, you should not do this if you use Audyssey room correction software. Audyssey specifically states to set both sub's phase settings to zero and allow the Audyssey filters to adjust for any phase differences.

Yes, I didn't change anything in the end. As audyssey seems to handle it; I had put them to zero, ran the setup routine, flipped them around to test only to note no improvement.

Does anyone else find it amazing how much lower the ULS-15 seems to play versus practically everything else?

Hey Pete have you ever thought about making an unique EQ for your line of subs similar to how Paradigm has PBK for their subs?

Pete? Where are you?

Another question Pete, if you get a mid-bass module does it HAVE to be connected to the ULS-15 or can it stand alone in another part of the room?

Hi Kimwyn,

That is a good suggestion, we will certainly consider that!

Regarding the MBM, yes, it is fine to keep the MBM separated from the true sub! Try to place the MBM close to the listening position, and place the true subwoofer in a farfield corner. Set the subwoofer distance on the receiver equal to the distance from the main listening position to the MBM.

Sincerely,

Pete - Hsu Research

just bought uls 15 but have a question regarding uls 15 calibration (that my previous subs including vtf2 mk3 ) that when i dail all other subs to 10'clock avr mic set sub level to like -6db or even sometimes -8db but with uls 15 when first i set it to 10'clock avr set its level to like +0.5db and when i dail it to like 12'oclock its now near -7db mmmm is my sub fine coz on other subs 10'clock is very high for me but for uls 15 10'oclock is quiet low volume and 12'0clock has same impact as opposed to other subs
please reply asap i'm scared

The amps on the two models are different. Continue to adjust the ULS-15 gain up or down until the AVR reads 0 or -1 -2 after calibration. It looks like 10:00 is real close to being optimal on your sub. I have mine set between 10:30-11:00 and my AVR is at -1. Relax and enjoy.

thanks bro my 2nd sub will be soon here hsu uls 15 is awesome man i found new layers of music which i don't know before just simply awesome but i guess one sub is very much localizable coz my room is small in width just 12 feet so i guess adding 2nd sub smooth out the localizable bass right and about wirelss is it working fine if i use it i haven't try it yet i want to ask this coz i'm playing games on ps3 so i guess blutooth remote creates some interference am i right

i luv hsu uls 15 deep bass........ have fun brothers

You one sub is localizable because you are running it hot. Like I suggested on the Hsu forum, turn down the gain (volume knob) on the subwoofer to around 10:30 so that after calibration it will be set at -1 in your AVR setting. These are my recommended setting on the ULS-15 (FOR YOUR ROOM) that you should try prior to running Audyssey:

volume on the sub to 10:30
xover toggle switch to off
ULF trim to halfway between 16 and 50
auto switch to on
phase switch to 0.


What crossover is now being set on your AVR and are your speakers set to small?


On your question about the wireless hook up just try it and see if it works. Mine are wired. I have never used the wireless hookup.

Well that is a starting point prior to auto cal. After auto cal you can change that knob if you like. Your room is really to small for the 16 Hz setting to make a difference but I also would not want you to miss out on some of the lower frequencies, so halfway is a good starting point. You might also want to try near corner placement since you only have one sub. At least until you get a second one.

You can try and see if you notice a difference. If you look at my room it is over 10,000 cubic feet so I am able to take advantage of the 16 hz setting. YMMV
