Personally I like the look...it gives it character other than black box with round ports or rectangular slot. But to each his own

So far I can already feel the difference but it's obviously cuz I had 2 much smaller subs. I've got no experience with any other sub in it's class so It'll be a much bigger difference to me than others who have owned various subs. This thing is so big the box of the PB10-NSD fits inside it's box with all the foam packing. Was a good workout moving it around by myself. Will play around with it more this weekend. The kids wanna watch The Last Airbender so I guess that's it's first movie...

Got mine as well. Mine wasn't signed so I guess it is just random. I love the sub so far. I had the DLS-4000R and what a difference it made.

Well, I don't want this to become a thread where we bash other products, even though I would *not* be bashing the other sub I fear that is the way that some people might take it.

Having said that, let me put it like this: my prior subwoofer was about 9 years old. So I think it is fair to say that there have been improvements since then, and that would apply to the manufacturer of my old sub as well. In other words, I'm fairly sure that if I bought a new sub from the same manufacturer, I would also feel that it was a pretty good upgrade over what I have now. Keeping all that in mind, my prior sub (now for sale) was the SVS 20-39 PC-Plus (a cylinder sub), which has given me 9 years of service and is still going strong.

By the way, I also have an 11 year old HSU VTF-2. The VTF-15H kills that one!

It's taken me two days to really spend time with the sub and understand just how much the "EQ" and "Q" controls effect the room response. This sub is really incredible and the use of the "EQ" and "Q" controls makes this a completely different sub. Depending on how these are used you can literally transform the sub into many different subs. Changing these controls is like swapping out one sub for another or being able to have an external EQ with different room response setting for different kinds of movies and music.

I didn't realize just how important the "EQ" and "Q" controls are until I EQ-ed the sub with my BFD. I used my BFD to EQ the sub with the sub set to EQ1, Q=0.7 and had a nice house curve built in. Then by flipping over to EQ2 all of a sudden the curve was the same, but all the frequencies went down and depending on the Q setting, I could even change the response curve. Through the use of the Q control you can have different response curves for different DVD/BD, whether movies, music or just CDs. These features are very useful for say movies that are really bassy and dig deep and you play at a medium volume vs. a BD like War of The Worlds that is way overcooked in the bass and I want to play it loud, but still want to feel that deep extension. I can simply flip the EQ from EQ1 to EQ2 and change the Q from 0.7 to 0.3. Now I still have a sub that digs deep but let's me play very loud too because the response has now flattened out and lowered. The combinations of EQ and Q settings from 0.3-0.7 are ridiculous(in a good way though). You really have to graph out the response curves to see how the changes effect the sub and the room.

Imagine having 10, 12, 14? subs all with different room response curves and you'd swap in the sub you want depending on the material playing. Or imagine having a single sub with an external EQ that has memory settings for 10,12,14 or more response curves. The EQ and Q control combined with ported or sealed modes makes this sub really special. I just need time to graph out maybe three or four EQ and Q settings that fit the different material and the way I like it.

As for the sound what can I say, the sub hits hard hell and sounds fantastic. You can even alter the sound depending on the settings you choose. On the first night I thought "yeah the subs OK, but my VTF3-HO w/turbo wasn't too far behind". Well that changed last night after I learned how to use the EQ and Q controls and graphed the results of changing the settings. Now the sub is a completely different animal. You really just need to tweak this monster to your room. Now the HO isn't even in the same league as the 15H. The VTF3-HO w/turbo is a really powerful sub, and sounds great, but the 15H really is at a different level. It can be smooth or punchy all depending on the settings and it can also have more or less low and/or mid bass depending on the settings.

My theater is in our finished basement, and the theater part is closed off, 13x24 with carpet over padding over concrete. Even in a basement theater the sub really moves a lot of air and shakes the hell out of my room and the entire house. This is one serious sub and I can't imagine having it upstairs on a wooden floor. I played the Iron Man 2, and Matrix Revolutions BDs. I used 1 port open, EQ1, Q=0.5 for IM2 and set my pre/pro master volume at -17 and showed "un-corrected" peaks of 100dB on my RS meter(remember I have a house curve built in and I also get a lot of room gain below 18Hz and the BFD can't EQ below 20Hz). The scene when IM jumps out the plane was unlike I've ever heard it and the scene when whiplash spins his whips and they hit the ground 7 or 8 times fast in a row towards Tony was just ridiculously strong. You'd really have to feel it to believe it. I only played these two scenes, but several times and I imagine the rest of the movie is equally as powerful with the H15.

Then I put in Matrix Revolutions. I tried the scenes when the machine speaks and the final battle with the water ball explosion. The machine speaks and water ball explosions both go down to around 5HZ, so I wanted more headroom and the deepest extension so I used 1 port open, EQ2, Q=0.3. and set my pre/pro master volume at -12(revolutions is mastered at a lower volume for some reason). It was really scary how strong the bass was. With my room gain below 18Hz the water ball explosion has always been a demo scene for me with the HO, but with the 15H it's really is scary how strong the bass is.

I'm going to try some more sub settings with, concert BDs and music CDs. The main thing for me has been understanding the effects the EQ and Q controls have to get the most out of this beast. I haven't even tried it in sealed or two ports open mode yet, but IMO with this subs fit, finish, performance, and the flexibility of the settings, if Hsu had charged 2K I would have paid it, but I'm very happy with the price right where it is..

Just a heads up, be careful when you are pulling the port plugs in and out of the VTF-15 H. I got one a little stuck and I ended up ripping off a piece of the port plug. Not a huge deal, but I thought I'd post this so that others know that's a possibility. Didn't have this issue with my old Hsu sub.

Legairre, when you get a chance can you take a picture of the HO next to the H15 and post it for us?

After reading what others have been saying, I am seriously considering selling both of my HO's and getting 2 H15's instead of just adding one H15 to my 2 HO's.

Decisions.....decisions

I'm sorry Kevin, I sold the HO before ordering the 15H. The HO was eBay with a buy it now and sold in about 12 hrs so yours will probably go quick if you do sell them.

No problem, thanks. If you don't mind, could you PM me and let me know how much you got for it?
post #341 of 5101
I remember when I bought the HO back in '05/'06 I told my wife it would probably be the last subwoofer I would need. I'll just have to live vicariously through you guys

You guys forget, he said "probably", in that sentence. As much as the wife wants to complain, she can't argue with the dictionary, probably is not definitely.

When it comes to this hobby, never say anything like that, especially to your wife.

I would push that "probably" as much as possible.

hey KLee. thanks for the thread

just a suggestion, you might want to put a link to the sub in your first post and links to any other relating articles or reviews
post #347 of 5101
So it looks like this thread has convinced me to buy this sub. I need a favor though. I'm not new to HT, but I am new to adjusting EQ and Q. My current setup just has my receiver adjusting the decibel level for each channel. Can anyone direct me to a good "EQ FOR DUMMIES" post or place on the Internet? This sub will be in a dedicated HT room upstairs on a wood floor so whatever I can do to perfect that sound and not break my house would be helpful.

I've learned to say things like "this sub doesn't work well anymore" and "I'm tired of the blu ray player being so slow". And also pointing out things I see on tv or in mags, "wow that looks really nice, I bet that sounds great". Say things w/o saying that you want to replace or buy new right now. Plant the seed for a later upgrade.
I just got a new sub, but I'm already trying to figure out how I can upgrade to this Hsu VTF-15" next year.
post #349 of 5101
Legairre is a great guy. I bought his vtf 3 ho. This is my first good subwoofer. The vtf3 ho is a beast but from what I have been reading I might winf up getting the vtf 15 maybe next year for my b-day.
post #350 of 5101
Robert, how the heck are you? Great to see you on the sub forum. I didn't know the HO was your first sub. So you got a monster for your first sub. My first sub was back in 98 and it was a 100 watt 8 incher. I think I'm on sub number 8 if I count the little 8" sub.

Now that you've got the sub bug you'll probably upgrade like some of us do and every couple of years when you get upgraditus. Is the HO still pounding your walls pretty good? I'm trying to figure out how to sneak another VTF-15H into the house without my wife knowing. There's just no way I need another, but this isn't a "need" it's a want thing. I may need to get earthquake insurance if I get a second one though.

I forgot to ask did you take the HO out the car alone or did you have help?
post #351 of 5101
Hey! Yeah I got that monster out myself but man what a work out. Yeah the ho is great. But now I got the upgraditis! I need some new front speakers. I'm looking for something with amazing highs and great imaging, maybe paradigm. The vtf3 got the bass covered(smiling). I saw your review of the vtf 15 . Holy &$&@. That thing sounds crazy. When u get a chance u got to come by to here the vtf ho in my house. My wife heard it and thought a plane was flying way to low. Lol

Rick, a good explanation of the features of the sub is here in the Owner's Guide. That is a good starting point. There is also seperate equalizers for bass if you want to be a perfectionist, these are available from SVS and Velodyne, and there is also Anti-mode, which is a bit cheaper and can achieve the same result. Thread about anti-mode here. I would start with experimenting with the settings on the VTF to get it where you like it, and if you aren't happy with the sound then try out antimode.

Which Paradigms are you looking at? If you do go with Paradigms let me know. I know a dealer that will do 20% off.

Congrats and great write up Legairre. Have you found a setting yet where the sub would work with music as well as movies without having to make adjustments to the sub? IOW set it and forget it (wasn't that on a commercial I saw on TV somewhere) So far I'm liking what you all are writing about but I do not think I would want to have to change settings between music sessions and a movie. I do not have to do that with my present subs.

Thanks for the nice comments. I could easily leave the 15H in EQ2, Q=0.7, because I love the low end extension that I was use to with my HO w/turbo. You really don't need to keep adjusting the sub. It's just that it's nice that you can tweak it to find the setting that works best in your room and then set it and forget it. With other subs you don't have a choice and with the 15H at least you can experiment and find what works best then just leave it there.

BTW, I still need to try the 2 ports open modes so I might change my mind as to where I want to leave it after I try those modes.

Good to hear. Well then, I'll stay tuned for any new developments.
post #357 of 5101
I planned on trying 2 ports open over the weekend but never got around to it. I'll have time tonight and will post later.
post #358 of 5101
From HSU Website: "Adding the patent pending turbo doubles the port area for extended bass mode, allowing the VTF-3 HO to move as much air as four VTF-3 MK2 models in extended bass mode with the same level of port noise."

Too bad you sold the HO already, I would love to know if there is any real discernible difference in a blind test.

I'm just the opposite. I've only used it with both ports open, haven't tried with a port plugged yet.

I always ran my other subs with one port plugged.
post #360 of 5101
Ok. My VTF-15H arrived!

Ehhh. I will not bother saying anything, besides it is the best subwoofer I have owned!...As simple as that... WOW!

Will post SPL readings soon with more detailed review, but I am getting new SPL room records.

I am so happy, I even feel Dr. Hsu designed this exactly for my tastes.AHHAH

The feets, the cabinet construction(fit &finish), the triangular ports, the driver, all are excellent... This product has at last ended my quest for a subwoofer, it is really great!

I heard Jurassic Park 3 (DTS), in the scene where the two dinosaurs fight, and the sub ports were literally blowing up the curtains...Since those curtains are very very heavy, this is a first in my room!
I had in that same corner the ULS-15 and the A7s-450, and they were good... but this thing is putting out more bass than the two together...I just can't believe this. It even makes me sick after a while of hearing it.
It has extremely good transients in Die Hard 4, and hard hitting midbass in movies like LOTR3 (Oliphants stomps).
