If you have an iPhone/Pad, you might try this:

"Leverage the camera on your iPhone or iPad to measure rooms and generate accurate floor plans in just a few minutes."

You can put your hand on the surface that you intend to place the device with the HDD. If you don't feel tremendous vibration, you should be fine. Placing the device on a shelf that is attached to a wall may not be a good idea. An equipment rack sitting on the floor is most likely fine, especially if it's a concrete floor!

That's bad ass. That would've been really helpful a couple of weeks ago when I posted my turd of a layout picture

Darn! The App says it's not compatible with my iPhone 3GS! I will try it on the iPad tonight. Looks way cool!

I am listening to a CD of Saint-Saens: Symphony No. 3 "Organ" and my VTF3.3 with Turbo is producing some bass that I can hardly hear, but only know that it's there due to my couch, windows, and picture frames rattling and shaking. I love it.

Nothing will find "rattles" in a room better than a HSU subwoofer and a good organ recording! A quality pipe organ can play cleanly down around 16Hz. My friends can't believe it when I turn up the volume when you really can't hear anything, but your chest cavity shakes! I find I can't play it for long, as I start to feel sick.

One of my favorite organ discs, was the second CD I ever purchased around 1986, Bach's Toccata and Fugue in D minor.

Hi dr_hsu,

Just bought the VTF-15H recently, in the process of hooking it up.

I had a general question before I even begin to experiment with settings (I'm pretty sure I'd be evicted from my small apartment soon )

I plan to use Belkin BG108000-04 Conserve Energy-Saving Surge Strip to switch off:

1. HSU VTF-15H Subwoofer
2. Pioneer Kuro PRO-141FD Elite 60" Monitor
3. B&K 200.7 Reference Series Amplifier
4. Onkyo RC-270 Receiver (with Pre-out)

Would this be ok or do I need to invest in something else?

My intent is to switch off the devices not-in-use.

Thanks,
Kris

I would just use the auto on/off function of the sub standby consumes very little.

You can certainly do that if you are really green, although as oztech said, the 15H does not draw much power with no signal.

Last weekend I purchased a Hsu VTF Mk2 off of Craigslist. The owner was knowledgable and had obviously taken good care of the sub, which worked perfectly when he demoed it.

After taking the sub home, I plug it into the outlet and the fuse immediately blew (power was off; volume low). A trip to the hardware store later, I saw the sub blow two more fuses immediately after being plugged in. Again, the power switch was set to "off," the volume was minimized, and nothing else was plugged into the sub.

I'm really hoping that there's something obvious I'm missing, because I'm confounded as to how something could have happened to the sub. I was extremely gentle when transporting it to my apartment.

Does anyone have an idea what might be up?

Sorry to say that the amp died.

I have the same problem with the blown fuse issue. Seems like a flaw in the design. Not sure what good a fuse is if it doesn't protect the amp. I have been doing some research and it seems common for hsu subs. It is not my intention to bash hsu but just want to see if something can be done to help us deal with our now dead amp.

Debating between the VTF-3 MK4 and the VTF-15H. I have a great room that includes Living and Kitchen area. Living room with HT is 20x20x12. Kitchen adds another 5x20x12 to the great room. Couch is 11 ft from the TV.

60% movies / 40% music. Was set on the MK4 until I started reading 15H recommendations for rooms my size. I don't need heart palpitations, but want to feel the low rumble in movies.

What do you guys think? Would the MK4 be enough to get a decent compression in my living room?

Thanks!

Are there large openings that lead to other areas? Please post a sketch of your room including adjoining rooms if linked via permanent openings. Indicate where you can put the subwoofer. Sounds like you are sitting close to the middle of a square room, not good for deep bass.

The purpose of the fuse is to prevent any fire hazard when something major failed in the amp. Putting a smaller fuse that lead to the need to change fuse when you play too loud just increases your maintenance cost and frustration.

Depends on how old it is I see amps of all brands fail as they get older most are do to bad caps or caps that are borderline failure.

Can the VTF3-MK4 work with satellites or small monitors crossed over at 100 or 120 hz?

Thanks

Attached layout. There are 2 entryways to the dining room on the right side of the room, but they arent huge. Living and Kitchen is all open air.

Thanks!

Really? Examples of these so called common failures?

the mk3 modals were tested to have a flat response above 200 hz, I don't think the mk4 would have changed that, so I believe you could use them with satellites.

The VTF-3 MK4 will go up to several hundred Hz without any problems. We normally do not recommend crossing over very high because higher frequencies are directional, so it's easier to localize the subwoofer (unless you place it in the front between the main speakers), and the image may be a bit narrower. With 100 or 120 Hz crossover, it should not affect the imaging much, but you may want to place the sub up front somewhere between the main speakers to make the sub non-localizable.

Can you include the dining room in your sketch? What I need are the dimensions of the adjoining room. Does not matter that the entryways are not huge. Bass will energize the dining room. Is you sketch to scale?

I have my VTF3.3+Turbo with crossover at 110Hz and it is fine. You can localize it though, so I have it placed directly behind the center of my couch, firing into the couch. It's great.

If you do a quick search, you'll find some but maybe you can ask Dr HSU who sounds like a very nice gentlemen if he can tell you how many have the blown fuse issue. I did a search trying to find out if anyone had a fix because it is really not cost affective to pay for shipping and service cost for a sub that cost $500. I do like HSU subs and would like to get some help for us owners on how to we can get the blown fuse issue resolved. I'm open to a DIY option.

Thanks to you and ShadyJ Good to know.

That must really have some impact.

So even though the sub is in the back of the room by placing it in the middle it doesn't seem as though the sound is coming from the back of the room? Is that a correct assumption?

I would likely be placing the sub in the front right corner or close to it.

Mid wall behind the sofa is also a possibility as I ran a wire back there. Can't wait till the house is done and I can start playing with the different locations.

Now I just need to decide on speakers.

Thanks

Revised the layout to include dining room and dimensions for all rooms. Unfortunately, it's not to scale. Only have Excel

Thanks

We have tried 150 Hz directly behind us and it's not detectable! Has tone directly behind, not to one side.

Place the sub about 6 - 8 ft from the left corner. A VTF-15H would be best for that space.

I did a couple of years or so and it worked great. Works better with my HB-1s
