If it makes noise when you adjust the volume control, it most likely mean some dust got into the volume pot. Does it make the noise when you move the volume control with no music playing? If so, move it rapidly up and down 10 - 20 times. That usually clears it.

Yes it does. Sounds like soft static. Or port chuffing. Without anything plugged in except the power chord. Thanks for all your help and the awesome product. If it were up to me I'd buy one or possibly four of everything you make.!!!!!!!!! In the mean time I'll be banking up for your mbm and your 15H's!!!!! Thanks!!!!!!!!!!!

Hey all. I'm researching various subs and several of the HSUs peak my interest, specifically the STF-1, STF-2, and VTF-1 MK2.

I recently purchased a Denon AVR-1712 and am expecting delivery of a pair of Ascend CBM-170 SEs. I will use them for movies, video games, and music. Some time within the next several months I would like to get a sub. Budget is $400-500, which includes shipping and any applicable taxes. If I can achieve what I want with a $400 sub great. If not I am willing to go up to $500.

I have a square room, measuring 11'x11'x8', which presents a lot of problems. I've researched a lot and some people have very strong opinions on the issue. For example, that a sub will do more harm than good and is not worth it in a situation like mine, UNLESS expensive room treatments are used. Even then it's not ideal.

I need to figure out if a sub will most likely work in my room (sans treatments) and then which one to choose. I could use some help.

Here's my room layout: 11'x11'x8'



The X's mark proposed speaker placement.

I am looking into replacing my dresser with an AV furniture stand, one that has a center opening. I would then get rid of the small AV rack on the left.

I read that Dr Hsu frequents this forum so I'm hoping he responds as well.

That was it. No more static sound. perfect. smile.gif and have decided the hum is EMI. Appreciate it!

What size space does the door lead to? Leaving the door open will help breakup a very square room. Also, how deep is your closet? That again effectively make your room less square. Acoustically for the bass, the closet is part of the 'space'. e.g., if the closet is 2 ft deep, then your room is effectively more like a 11 x 13 room. Given your room layout, I would place the sub between your AV rack and the dresser. A VTF-1 MK2 will give you the ability to fine tune, and get a more musical result, while an STF-2 should provide adequate bass.

Thank you for responding.

The door leads to a hallway that is 25 ft long. The closet is 2 1/2 ft deep and 5 1/2 ft wide.

Here's a layout that includes the space outside my door



If I replace my dresser with an AV furniture stand and get rid of the AV rack should I place the sub in the same spot, between where the dresser and AV rack were, or in the upper left corner?

So even given my room dimensions I should look beyond the STF-1?
post #5833 of 6176
I would stick with the STF-2. Front left corner should be fine. Crossover at 80 Hz. Keeping the door to the room on the right side (on the other side of the closet) open (and of course your room's door open as well) will give you much better deep bass.

Thanks dr hsu. Appreciate the help.

I didn't think to include the closet and area outside my room as part of the equation. I was thinking that my door would have to be closed for ideal acoustics. Out of curiosity, how would the sound change if my door were closed?

I know this is the hsu thread, so I don't want to take the thread offtrack, but I was hoping you could provide some insight on some other subs I'm considering, specifically the Outlaw LFM-1 Plus, SVS PB-1000 and SB-1000. The last two are relatively new, so even as good as SVS subs are, I'm not sure about them. Is the LFM-1 Plus too much sub for my room, if there is even such a thing? I hope you get what I mean. What model in the hsu line does the LFM-1 Plus compare most closely to?

I may spend the extra money if I can get an appreciable improvement, but if I can spend less and get a sub that performs well for movies and music in my room, I'm fine with that. I won't be listening at reference levels, more like low to moderately high.
post #5835 of 6176
Drove down the Niagara Falls yesterday to pick up my VTF3-MK4's, man were those boxes big, squeezed it all in my SAAB 9-5. One had to come out of it's box. I also picked up my Emotiva XPA-3

When I built my theatre I had wired the sub connections in to the sides midway between the front and back. I know understand that this is not a good place to put subs, so I squeezed them in the front on either side of my mains. The only other option is going to be behind my seating in the back corners.

So far I'm extremely happy with the sound, it will kick you in the chest, but it's nice and tight. I have the Q control set for .5, one port sealed, crossover at 60 (even though my denon takes care of it), phase 0 on both, operating mode in EQ 2 and the volume just below 9 o-clock.

I put Thor on this afternoon, and wow is all I have to say. With the subs and the Emotiva my system has really come alive. (mostly from the subs).

Any thoughts on sub placement would be appreciated. The room is 16' d x 13' w, closed, one solid pine door front left. Carpet with dri-core sub floor, 7.5' ceilings etc.

I attached my old plan, you can see I never did a raised floor in the back, not enough room. But the main dimensions and locations are correct.

Cheers.
post #5836 of 6176
Welcome to the Hsu family! The front locations are great. Keep them there.

Lol I don't think the Dr. wants to openly discuss his competition, that wouldn't be tactful. I will tell you there is no such thing as "too much sub". You can always turn the volume down if the bass is too much, however you may hit mechanical limits if you try to turn it up when it is not enough. A sub more powerful than your needs has advantages. First, when it doesn't have to constantly operate near its mechanical limits, this keeps distortion down by a great deal, so you get a cleaner sound. Second, when you don't have to push your sub hard, this is better for the long-term reliability as the amp won't get as hot and the woofer doesn't have to flex as much. Third, it's always good to have extra headroom. It is very easy to get compressed peaks in bass at your listening position, lots of headroom is good so you get less compression and a more faithful presentation of the recording.

The LFM-1 Plus is roughly equal to the VTF2 from Hsu. It might have slightly more output due to the more powerful amplifier, but it wouldn't really get much louder, maybe a decibel or two. The new SVS subs look to be on the level of the VTF1, their specs are one the level of the VTF1 anyway, and they are said to be about 3 db down from the NSD subs which would likely put them in the VTF1's range of performance. This is all just my own speculation, but I don't believe I am wrong. If I had to choose between any of those and the VTF2, I might swing for the VTF2 because of the inclusion of the Q control and the performance lead it will hold over the SVS subs.

Thank you. I was hesitant to ask the question. redface.gif Since dr hsu designed the LFM -1 Plus I thought he might answer. I think I've got most of the pertinent info regarding the LFM-1 Plus, including it's comparison to HSU.

The VTF-2 is beyond my desired budget. At it's current price the VTF-2, with the inclusion of shipping and taxes, is $655 for me. I can get the VTF-1 for $529 and I still get the Q control, which would be nice to adjust for movies and music.

Has the VTF-1 gone on sale in the past and if so how frequently? I'd be willing to wait if I could save money. I thought about B stock, but according to the HSU website "All sales are final, no return, no exchange, no 30 days trial offer for B stock or clearance items." I'd rather buy new.

The Hsu subs seem to have a sale cycle, they usually go on sale for a couple months for a couple times a year. I wouldn't balk at buying B stock as its still covered by the normal warranty if I remember right.

I'll keep my eye out for sales then. Hopefully the VTF-1 goes on sale within the next few months.

B stock have the normal warranty. If that was my only real option to get a discount I think I might bite, especially considering that I'm doing my homework, finding out as much info about subs in my price range, and therefore I doubt I'd return the sub I buy.

Hi,

I am expecting my 15H delivered today. I was reading the "Owner's guide" earlier today and came across the statement "Keep the subwoofer at least 4 feet away from computer hard drives in order to prevent the hard drives from being erased."

I am hoping to place 15H next to (8" ~ 10" with media center wooden plank in between) my 1st Gen PS3. Any suggestions?

Technically, I shouldn't be bringing my Laptop next to 15H? or am I paranoid?
post #5842 of 6176
I have had my HTPC suspended about 12” above the top surface of a ULS-15 for about a year and there’s been no problem. Additionally, I have attempted to erase or damage hard drives using bulk magnetic tape demagnetizers but the target drives remained unaffected. I conclude modern hard disk drives are a lot more immune to stray magnetism than we give ‘em credit. That leaves the longer term effects of spinning in a magnetic field unexplored and while the potential for harm cannot be dismissed, I’d be surprised if problems arose. I continue to monitor. smile.gif

Sorry to interrupt but my sub vtf3 mk4 is side firing with 2 ports open from the back of the sub. The ports are like 5 inches from the wall and the side firing woofer is about an inch from my wood component rack. How far away does the rack need to be from the sub or is an inch distance ok?

I am sure it would not be an issue. I would be more worried about vibrations if you put the PS3 on top of the sub.

I would go for 2" spacing. Do you have the grille on? If it's an inch from the grille to the component rack, simply remove the grille. That would give you the necessary clearance. 5" for the ports is fine.

Yes the grill is on but I will just move the rack further away since I like the grill on. Why would an inch from the rack be bad? Sorry I am just learning here. Thank you!!
post #5847 of 6176
It becomes more of a 'slot loading' effect if the gap is too small. Effect is minor. Even if you cannot make the extra space, it should still be fine.
post #5848 of 6176
dr hsu, if I go with the VTF-1 MK2 and position it in the upper left corner, either next to the dresser or farther to the left if I get rid of the AV rack, what direction should the ports face? How far from the top wall should the sub be?

Appreciate your insight. I have the PS3 inside the media center. 15H will be on top of auralex gramma next to media center on the floor.

I would certainly go by Dr Hsu recommendations for your room. BTW very nice set up. Those VTF-3's do rock !!biggrin.gif I have two as well and very happy with them. I have mine placed in the front right and left corners. I was going to place them on the side walls midway, but I have a love seat on one side and a small bar to the right so It would be hard to put mid wall.

Here's more info on placement that is suggested by others about the mid wall being a great spot for a rectangular room.

Figure 1a. Two Sub Midwall Placement
If you are running two subs, the ideal locations for them in a rectangular room are on opposing vertical or horizontal midwalls. Two subs configured in such a method work nearly as good as four subs configured via our 4 Corner Placement recommendation. You will however need to stack two subs for each location to achieve the same output as the 4 Corner Placement unless you chose two subs with twice the output capability of the four subs you were planning on using.

Although it's been incorrectly touted as ideal to place four subs at each mid-wall location (since it offers consistent frequency response for each seat); this is NOT recommended because it acoustically less efficient than just employing a single subwoofer! Thus the maximum available output level of four identical subwoofers placed mid-wall will be LESS than one subwoofer located in the front corner. In our opinion, this is a waste of power and money. We recommend avoiding this option for four subs unless you are stacking them for two locations
