I can't order til this coming Wednesday so I have a few days to mull things over.

Unfortunately, no. It's an additional $69 for shipping.

Got bored today and decided to rerun Audyssey MultiEQ XT.

At the beginning it nicely helps you set sub gain so its not a big guess causing you to rerun. I set it at 78db on screen, then ran Audyssey. The result was -2.5db, and in the past Ive been boosting about 3db. Ive read that some folks run a little more hot, so I went with 5db to +2.5db. Im pretty happy with the bass, has a little more punch with regards to where my volume level is set. Using Audyssey Movie with Dyn EQ and Dyn Volume OFF.

My sub settings are:

Gain - 8:30
Phase - 0
EQ 2 / 2 Ports Open
Q - 0.5
Xover out

In the past Ive always ran Audyssey with EQ1 1 port open, then changed to EQ 2 2 ports open (HSU Recommendation). Out of curiosity I just left the VTF15 in EQ2 2 ports open this time when I ran. When mine sits its kinda a PITA to tinker around back.

YMMV.
post #3183 of 5093
That got me to thinking. Why would I run Audyssey with one setting and then immediately change it to another setting? Wouldn't Audyssey have set the sub up under the settings it detected at the time and therefore making the new setting uncalibrated?

Maybe it's something that I just don't understand.

I have seen Dr Hsu's explanation and it makes sense, but I also question what is the overall affect changing the sub parameters after running audyssey and applying filters. I just watched an action flick and it sounds great, so I dont think I hurt the performance smile.gif

hi all. first time poster here with a couple questions for the experienced. scanning through all the forums has been incredibly helpful and taxing on me at the same time. i'm ready for some serious bass now that i have built a new house with a dedicated theater room. i am considering a vtf-15h, possibly two for my room. i'll describe my room and my wants to you all first. dimensions for the room are ~19' long x13' wide x8' high, perfectly rectangular with a door to seal it. but it's in a basement with acoustic drop ceiling tiles...really lightweight black fabric tiles with what seems like compressed batt insulation on top of them, so i know it's not completely sealed. using pre-outs of denon 3311 receiver with sonance 875d amp to provide power. speakers are polk lc series in-walls and current sub set up is dual klipsch rw-12ds. i prefer the deep house-rumbling bass that you feel through the couch, and that's what brought me to the vtf-15h. given my setup, should one sub provide that for me, or would i need to do duals? i understand about duals more evenly distributing the sound, but that's not my concern right now. i can always add a second if i want it evened out in the future. also placement for duals...would both up in the front corners be better or diagonally across the room be better? problem for the latter is, the one in the back would be right by the seating. does anyone near nashville tn have this sub and would you be willing to allow me to hear it? thanks in advance for any response and in general for everyone's wisdom and time. mark

I would start with one. Given your room dimensions, I think one could be more than enough, but everyone is different

For two subs, you will need to experiment, but for a rectangular room I like this placement:

I started with one but my room is much larger, 4500^3 give or take a foot. I was happy with one but I really wanted to even out the bass amongst some other seats, a pair helps in that respect.
As much as I like hearing other subs/brands, I can honestly say that I don't feel the need to go beyond the pair that I have. In the near future I plan on doing a DIY project for fun and for my own education.
My music tastes are varied, HeavyMetal/Rock to Classical. Films are my main drive with music being second.
The 15H has many options for tailoring the sub to your tastes. There are some good offerings out there but the 15H was priced for my budget and I don't feel there is anything better at that price range. ( I bought them in rosenut, it's a really nice finish).

It's really hard to give an opinion without sounding like a AD and this is just my opinion. wink.gif

Dr Hsu is really good to work with if you have questions etc.

Anyways, as Ack_Bk said, start with one. There are gains to be had with mulitple subs but you may like just the one. As to placement that seems to be room dependant though corner placement is usually tried first.

Agreed with Sputter 1 for one sub, start with corner placement in the front room. And batten down the hatches smile.gif
post #3189 of 5093
thanks for both opinions. i've never heard a sub of this caliber so i don't really know what to expect. i hoped one would fulfill my needs, so i'm glad to hear you both say start with one. if need be, i can always add another. in no hurry, but i'm excited to pull the trigger

Audyssey tries to give you a flat in-room response. My idea is for Audyssey to correct for the room anomalies, not the sub's characteristics. By setting the sub for the flattest outdoor response, Audyssey will just be making the room 'disappear'. After that, you can use the controls on the sub to get the type of bass you want to hear - tighter bass turn down the Q setting, lower distortion and more headroom from 22 Hz up - two ports open, ultra low bass extension - one port open, for example.

Where do you sit in that space? One should be just fine. If you have the front speakers in the corners, you can place the 15H between the front right speaker and the center channel (or front left and center). If it sticks out too much, you can also place it sideways. Set the sub to one port open, EQ1, Q=0.7 for Audyssey room calibration. Start with subwoofer volume control at 8:30 (a bit below the first tick). If Audyssey sets the sub out level too low (e.g. -8), adjust the sub volume lower and re-run. Aim for around 0 dB (+/- 3 is fine). After calibration, set it to two ports open, EQ2, Q=0.3.

Understood.

So I'm sure it's been asked but is the uls 15 worth the few extra bucks? My room is roughly 30x20 with 20' ceilings. 90% music use.

I have 3 reclining seats centered just off the back wall and three more centered about 6' off the back wall. i will be sitting in the front row. and thanks for the info for audyssey. i may have a pair located nearby for sale, one brand new sealed in the box and one used briefly from a guy who bought them new before realizing they were too big for his space. me, i'm not worried about their bulkiness. but if that falls through, i'll be buying new. either way, it's exciting thinking about the upgrade! is warranty transferrable for them? he said they are just a couple months old
post #3195 of 5093
Big room. I would definitely go with the VTF15h in there. You don't want to be sitting in a bass null in a room that the sub can not pressurize. If you were to get multiple subs, I think the ULS would be the way to go.

After getting my 15h Saturday and dinking around just a little bit on my own, I used these suggestions for myself, but forgot to open both ports and change to EQ2. I had yet to watch a full movie, so I went with one that seems to have a good rep around here for good LFE and threw in Immortals. Wow. I know there is still some adjustments that I can make, but this thing is amazing. I had to give my wife a huge kiss after the movie because she let me get it for myself as an early Christmas present. She loves it too, but feels like the neighbors hate us now more than they did before.

Just got mine unboxed last night. Couple Qs and comments:

The manual doesn't seem to mention the rubber feet that are included. If I'm placing on carpet is there any need to install the feet?

The unboxing instructions could be a little more clearly written. At first I was like "you really want me to flip this upside down to open it up???"

My Denon 3313 Audessey setup instructed me to set the sub at 50% power for testing, is that generally a good place to set and forget, and let Audessey balance it out?

Now that I think about it, I don't remember there being a CD in the box. Will have to check that when I get home.

I thought the port fillers would be like a pillow you could slide in and out of the channels easily, was surprised that they seem more like 'stuffing'. I haven't actually removed one yet, how big a PITA are they to put back in? For maximum bass extention I need to remove both, correct?

No issues removing the feet if you are on carpet.

I would set the power at 1/3rd, 50% seems awful high.

Maximum output is both ports open. Maxiumum extension is one port closed. Checkout the Hsu forum, there is some great info there and some polls as to what people are doing and like.

You want the foam to fit tight, it has to block the port fully. I have had zero issues plugging and unplugging the ports.

As Ack said, 50% is a lot, where are you sitting in relation to the sub? down the street? wink.gif It's a lot of gain, set around 9:00 would be more expected.
post #3200 of 5093
OK, 9 o clock to start it is, will keep the feet in their shipping box, will check the packing list area for the CD, and will start with one port open and check the Hsu forum for more details.

Pics soon! I have it set next to the stereo rack currently, the room was pre wired for 5.1 with the sub spot up against the front wall. I was concerned putting it right next to the mains would overwhelm them, but it seems that up against the wall in a corner seems to be the place most folks have the best placement and my current spot 1/2 up the room is in danger of being in a null so will test both spots.
post #3201 of 5093
Not sure why I’m asking this as it’s too late to change it. I’m remodeling my room after a flood (closing it in) and I’ll be putting my 15H under a DIY rack enclosure. It will sit on isolation pads and then on top of a MDF board with rubber wheels attached to I can move the sub if necessary.

The pictures below shows the space its going in. Since it’s forward firing and ported I assumed there wouldn’t be an issue with it enclosed like that. There will be an acoustic cloth frame covering the front (enclosure will be vented).

I thought I had a more recent one but here it is during framing:


Stand:


If the wheeled stand/platform is no good I could just put those furniture moving pucks under the isolation feet?

I didn't get a CD with mine frown.gif Checked everywhere and nothing. Didn't bother contacting Hsu since I would probably have to pay for shipping or duties to get it.

Can any one make a FLAC rip of it?

If I remember correctly, Hsu has an agreement to distribute those recordings with the Boston Audio Society, but that agreement is only valid for the USA, so Hsu can not ship out those CDs to other countries.

Confirmed that my CD was in the packing list outside the box. Glad I had not tossed it already! Didn't get to play last night, might be actually going to a theater tonight, and going to NJ over the weekend so might not be till next week that I get back to setting this rig up!
