post #5491 of 6210
Dr. HSU, I moved the sub behind my recliner and ran MCACC. It set the sub at -6.0dB. Does that sound good?
post #5492 of 6210
You might want to lower the volume on the sub a bit so MCACC sets the sub out at between 0 and -3.

Okay, I'll report back after I lower it. I did have two other questions though. 1.On the test cd that came with the sub, there are test tones that go down to 16Hz. I'm not going to hear them because my sub only goes down to 18Hz,right? 2.How many inches from the wall should the back of the sub be?
post #5494 of 6210
Depending on your room, you might still get significant output at 16 Hz. If you are sitting at one end of a 34 ft length room, for example, will give you strong output at 16 Hz.

It doesn't seem as if I'm getting as good as bass as I was getting when the sub was in the front right of my setup.
post #5496 of 6210
I have a VTF2 - MK3 sub and I have a Denon 2113CI to auto calibrate it with Audyssey

I am curious as to which sub setup is best to calibrate in (Max extension or max output)

I have been calibrating in max extension, with on port closed and the volume on the sub around 9 o clock.

Any feedback is appreciated!

Thanks
post #5497 of 6210
That is the right way to do it. After calibration, set it to two ports open. What sub out level does Audyssey set the receiver to after calibration? If it's too far from 0, you should re-adjust the volume control and re-run. It is best for the sub out level the receiver to be within 3 dB of 0 - better auto on function, and less risk of overload.

If the front location sounds better, go back to it! smile.gif

How would a single MFW-15 compare to a single HSU VTF-3 mk4? Would that be a lateral move or a significant upgrade?

Also, how does the VTF-15H compare to the VTF-3 mk4?

I went from the VTF3-MK3 to a MFW-15 at one point.  I would not have considered a MFW to VTF3-MK3 an upgrade at all, maybe the contrary.  Maybe someone else with MFW to MK4 experience can help you.  Not sure the differences between the new and old models either.  I do know that the Hsu had the option to tune lower so absolute low output cap prob would have been slightly better below tuning of the MFW(~19Hz) but seriously a single 12 or 15 isn't doing much down that low.....

 

I would go for the VTF-15H if it were me,  that should be a bit of an upgrade.

It generally sets in anywhere from +3.5-4.5.

Are you recommending I run the sub with 2 ports open but leave the plug in one of the holes?
post #5502 of 6210
No. Open both ports (no plugs) and switch the bass extension switch to the down position. If Audyssey is setting the sub out around +3.5 to +4.5, you can turn up the volume on the sub a little bit more and re-run. Do post your room layout (including adjoining rooms if linked via permanent openings) and indicate where you have the sub placed currently and where you sit in that space.

Dr. Hsu, please see my room layout and make any recommendations that you see fit, thanks so much for the help!

My room is 16 X 19 with cathedral ceilings that vault on both sides to a max height of 11 Feet or so. The vault extends through the room long ways, parallel to the fireplace.

post #5504 of 6210
I need the details on the adjoining spaces, the kitchen and foyer.

Dr. Hsu, please see attached updated diagram to show better detail of the ajoining rooms. Does this help?


post #5506 of 6210
The location for the sub is fine, but you can also try it next to the fireplace to the immediate right of the sofa, if that is possible.

So I re calibrated after turning the sub up and my results from Audyssey are now +2.5, which seems pretty good.

So my question now is, once I make the switch to two ports open, is my sub running 3 dB hotter than reference, because of the extra output that this mode generates?
post #5508 of 6210
No. The sub has higher maximum output capability in the two ports open mode, but the sensitivity in two ports open, EQ2 and Q=0.3 is about the same as one port open, EQ1, Q=0.7.
post #5509 of 6210
Hello,

I am here because I don't know what sub to get. I have heard it is important to get a sub that is powerful enough for you room and that room size and layout matter. But, I don't know hot to figure this out. I live in a town house and I want a sub that is good for music. One that will not sound out of place for movies. Something that can fill my room and compliment my speakers. I am not looking for a bass that will shake my living room because I do share a wall with my neighbor. I want a sub that does enough.

The HSU STF-2 and the VTF-2 MK4 seem neat. Are one of these overkill or are they even enough for my room?

My Speakers:
Boston Acoustic VR2
Boston Acoustic VRC
Boston Acoustic VRX

I have attached a floor plan of my living room. My ceiling is 9' tall. Thank you for your time.

post #5510 of 6210
A VTF-2 MK4 in the front left corner would be great.
post #5511 of 6210
As someone who owned a VTF2 MK4, and upgraded, I'd suggest you may consider the VTF3.

Dont look at it as overkill IMO, sub will just work less hard to run the room.

The VTF-3 MK4 is also on sale while the VTF-2 is not. That makes it even more attractive to step up to the VTF-3...

Even better lol. I love spending other peoples money wink.gif

I appreciate your suggestion about moving the chair further back, but the chair is about 9.5ft from the screen and I feel very comfortable from that viewing distance. I thought the rule of thumb with viewing distance was double the screen size ? That would be 10ft for my 60" and I'm pretty much there. Regarding the sub settings, are those what I use for MCAAC, or after I run MCAAC? I bought the sub because it goes down to 18hz, so will those settings get me there?

What more could a man want? How about a pole?

Just got my 2nd Hsu child last week biggrin.gif Ive my eye on a matching one on Craigs and here for a few months. I got my first Hsu sub from a member here, and as it turned out got my 2nd one from a member here too lol.

I had a VTF2MK3 and added a VTF3MK2 (basically same sub, newer generation, more powerful amp). I have a rectangular room with both subs up front about 1/5 away from the side walls.

I wasnt UNhappy with my single VTF2MK3, and it was pressurizing my room just fine. But there were a few times where my media was a little too much for a single 12" sub (full disclosure: I run my subs about 5db hot). I also wanted TIGHTER bass from all my sources. I knew adding a 2nd would do it.

Boy did it ever! Holy smokes...

I didnt feel the need to re-MCACC my room as my mains and surrounds hadnt changed. But I got my hands on a radio shack SPL meter and wanted to do it right. I set my receiver manually (Pioneer Elite VSX52) to 0db, pulled my sectional out of the way, and moved the subs to the middle of the room one at a time and gain matched them to 85db. Unrelated, but since I had the spl meter I level matched mains, center, and surrounds...MCACC was a little off. I then moved the subs to their respective positions, and after having a 20 minute convo with Leo at Hsu, set the VTF3MK2 to 1 port open and the VTF2MK3 to 2 ports open, Letting my receiver do the coss-over at 80htz.

Then the testing.

There arent words to describe my feelings. I fired up a 7 song test track I have, all bass-centric. Ahem. **** rocked. Hard. Hair on the back of my neck stood up. And best thing, CRYSTAL CLEAR, TIGHT, CLEAN BASS. I mean, freshly bathed baby clean. Then I watched the Avengers. Oh boy. The first 20 minutes of that movie are INSANE. Felt like I was getting hit in the chest. But ohhhhh it was so nice. Again, crystal clear, tight, and clean.

As previously mentioned I run my subs a bit hot. And even though I gain matched both, I adjusted my sub level in MCACC at -1.5db to soften it just a tad. Proceeded to spend the next 2 days re-watching movies and listening to music.

Dr Hsu, you make an amazing product. Im a fan for life. Simply amazing. Here's a pic of my new set-up (Ive since disco'd the blue lighting from the VTF3MK2 as my old one didnt have it...and it looked funny...also, wires and general clutter has of course been since cleaned up haha):

Thank you for you input dr_hsu and gadgtfreek. I really enjoyed the info on sub placement. The size and power of the VTF3 worries me a little. I don't want to be the guy that my neighbor dislikes because my bass is constantly bothering them. Finding that happy medium between enough bass and not bothering my neighbor seems like a difficult road to walk right now. Still, this is all in my head, I have never tried a sub in this living room. I don't ever hear voices or audio between our shared wall but I do hear their kids run up and down their stairs.
post #5517 of 6210
I was so glad to get out of apartments and town homes, and into a house. It's so hard to have a good audio setup without bothering someone.

You are most welcome! Glad you liked our subs... biggrin.gif
post #5519 of 6210
You are most welcome. Note that the sub only need to play as loudly as you set it. A larger sub does not need to play louder. It just has more headroom, goes lower, has better long term reliability and has lower distortion at the same listening level. Regarding neighbors, when tou want to crank it up, either invite your neighbor over to enjoy it with you or make sure they are out before cranking it up...biggrin.gif:p

Hello all, I just purchased a used vtf-2 mk3 from a friend. I ran Audessy on my newly purchased Onkyo 818. BOY, this thing sounds incredible corner loaded in my 13'x31' combo living/dining room. I was hoping Dr.Hsu would look at the crude draing I put together in MS Paint and make any suggestions. I'd LOVE to get a second for near field effect, but haven't found an exact one for sale. I don't think dual subs need to be identical, but someone correct me if I'm wrong. Thanks and keep up the incredible work Dr.Hsu and everyone at HSU Research.

PS
Not sure if it is critical for me to note, but I am running Emotiva ERM 6.2 for L/R ERM 6.3 for center, and ERD-1 for rears in a 5.1 config.
