You can get an analog SPL from Radioshack at around $20-$25. I was lucky and got mine on sale for just under $20. It helps a lot when trying to find out what your sub can do and to fine tune the auto-calibration.

If you have Audyssey you do not need an SPL meter however, I would get one if you are going to do the subwoofer crawl.

I own the HSU VTF3 MK4 and I hear that adding a mid bass module would make the system better. What does a mid bass module do different from what I already have? How is it better to have my sub along with the module?
post #5434 of 6210
I just unpacked my vtf3 mk4 and HOLY COW this thing is HUGE!! lol. Only problem is that there is no power cord in the box. Is there somewhere specific I should be looking for the cord? Either I'm really tired or I'm crazy. lol.


***EDIT***

I found it. It was inside one of the ports attached to a string rolleyes.gif I'm tired i swear. lol.

I have an Hsu STF-2 that is connected to my receiver (via the Sub In) and has been calibrated using Audussey. I have disengaged tthe crossover switch by moving it to OUT. I've read the manual for the Hsu and my receiver and am 72% sure I know the correct answer. smile.gif Does it matter what I set the Crossover Frequency Control on the back of my subwoofer? If so, what should it be set on? Thanks!

Leave the crossover at OUT and make sure prior to running Audyssey that the phase is seet to 0. Also make sure the crossover knob on the sub is at the highest point to run Audyssey.

I have a VTF2 MK3, I am using near field placement and running it in full ext. mode. I have a TX-NR609 which only has Audysssey 2EQ auto cal so it does not calibrate the SUB as fine as a the mulit-EQ, this I know.

I decided to move my furniture a bit and in turn felt the need to re-run Audyssey to compensate for the changes in my room. The Sub did not move, I just moved the Couch/chairs orientation. Either way after running it I tweaked my settings, adjusted cross-overs and distances to be accurate. I will have to re-run it again as the sub volume is a touch high- was EQ'd to -8db, I brought it up to -4. After doing this I used the CD that came with the Sub to check SPL and it is pretty much +3 or +4 db across the board, except at 63db where it runs -2. This is just in part an issue with my room. With that said the bass is just where I want it for output and sounds great. I can tell you I almost never run it more than -20db of reference. The sub is high passed at 100hz btw.

Do you guys think +3 to +4 db with volume at -20db from reference is running it too hot. If I run it this hot will is there any negative effects on the clarity of the bass?

I am bringing this up because I realized that for the last 3 or 4 months I have been running my receiver using Direct audio mode which I only recently found removes Audyssey calibaration. Oh and when changing it from Direct to Straight Decode (Audyssey enabled with no extra effects) there was an immediate difference in clarity of the bass.

Thanks ahead of time for your input.

When the crossover switch is set to 'out', it does not matter where you set the frequency to - the crossover is bypassed.

+3 to + 4 dB should be just fine. You should be the best judge for whether it affects bass clarity. Bass clarity is subjective and only you can decide for you. Simply reduce the sub out level by 3 dB and see if the bass clarity improves.

Adding an MBM will give you wider dynamic range, and for some room layouts allow you to have nearfield mid-bass without sacrificing deep bass performance. Please post your room layout including adjoining room details if linked via permanent openings and I will determine if an MBM is beneficial for you or not.

Hi all,

I just bought a VTF3 mk4 about a week ago, and i'm having some second thoughts and could use some advice/thoughts.

My room is relatively small, but is open to the kitchen and dining areas behind my listening position. I attached an image of the room, with the position of my couch and sub indicated.

My system is a yamaha RX-A2010 AVR, Emotiva XPA-5 amp and Polk LsiM bookshelfs/center/surrounds with some small def. tech mythos gems for surround back channels. I watch movies and listen to music, perhaps leaning slightly towards movies, but both are equally important to me.

I have the VTF3 in 1 port open, EQ1, Q 0.3. I ran the yamaha YPAO room setup, then recalibrated sub levels using a SPL meter.

The VTF3 sounds and performs very good, so its hard to fault it for anything. But i think i prefer the sound of a sealed sub.
My previous sub was a sunfire true subwoofer mk II, which i liked a lot. it sounded and performed great, with lots of very clean deep output, and no bad behavior, just a smooth roll off in output.

Where i noticed the VTF3 lacking is when it runs out of steam at very low freq. at high volume, such as bass mekanik's "bass i love you" track. in the lowest parts of this song all i hear from the VTF is port noise..

I think that a powerful sealed sub may be more what I'm looking for..
So, im considering returning the VTF3 for a ULS-15 or possibly SVS SB13-ultra (when its released later this summer).
I'd think that one of these should still give me plenty of output in my room, with better deep bass, and better behavior when it does run out of output...

Any thoughts or suggestions for my situation will be greatly appreciated!

Thanks!

You stated open to another room so it would be helpful as to give dimension in feet including ceiling height also what is the sub level set at along with the AVR output.

The room is 14'4" x 16', with a 8x9' dining area, and appox 9x10' kitchen (with counter between kitchen and living room). the ceilings are 9'. Its not a very straightforward layout, so the image i attached shows it more clearly..

AVR is set at -4 db, sub volume is at ~10 o'clock (though i crank it up a bit with some songs depending on how they are mixed/recorded). Ive mostly had the Q setting at 0.3, but I've been playing around with it a bit at 0.7

Try setting it to two ports open, EQ2, Q=0.3. Post your room layout including the adjoining rooms and indicate in your drawing where you sit and where the sub is placed. You may want to do the subwoofer crawl to determine where to put the sub for highest deep bass headroom. Any flexibility in where you sit? That can also greatly impact the amount of deep bass you get.

Hi Dr. Hsu,
I attached a pic of the room layout, but i should have embedded it, so here it is again: (actually, my room is a mirror image of this layout, but was the only pic i could get without sketching it myself)


I don't really have much flexibility in seating position or sub placement, though i could change the orientation of the sub (its currently placed with the ports facing the wall about a foot away, and the sub driver facing the couch (again, my room is a mirror of the picture).

Maybe I'm just feeling a bit of the "grass is greener on the other side" kind of thing regarding sealed vs ported, as the VTF3 really does perform well, but how would a ULS-15 compare in my room?

Thanks!
post #5447 of 6210
Try keeping the door to your bedroom open and see if that helps with the deep bass. Try the sub with two ports open, EQ2. You should still have great extension down to 20 Hz and a lot less port noise - you are doubling the port area.

It is hard for any sealed sub to put out as much low bass (20 Hz and below compared to what the VTF-3 MK4 can do.

If you love low bass, you should also try placing the sub in the front corner furthest from the garage. Any port noise will also be a lot less audible if the sub is up front.
post #5448 of 6210
I just saw the energy spectrum of 'Bass I love you'. It has strong signal in the sub 10 Hz range. No subwoofer will be able to handle that (other than getting the Eminent Technology rotary subwoofer). I saw some You Tube JL Audio woofers going crazy with that music.
post #5449 of 6210
hehe, yeah, its a pretty crazy song. I guess its unrealistic to expect any sub to "handle" that song. but i think I'm just used to, and like, the behavior of the sunfire subwoofer at its limits. it never did anything odd or different or bad, just got quieter.

i usually have the bedroom door open, haven't specifically experimented with open/closed..
There really isn't any where else i can place the VTF3. its just too big to go anywhere else in the room. I might be able to fit a smaller sealed sub up in the front corner, which is one reason I'm considering changing to a sealed model.
I'll try it in 2 ports open, EQ2 over the weekend.

Thanks again for your help!
post #5450 of 6210
You are welcome. Going to a smaller sealed sub will mean a lot less deep bass.
post #5451 of 6210
I'm going to pull the trigger on the VTF-2 MK4 within the next 2 weeks,. My receiver is a Pioneer Elite VSX-01TXH and it uses MCACC and not Audyssey. Do I use the same settings that are recommended for Audyssey with MCACC?

post #5452 of 6210
Yes, but you do not have to set the sub to one port open, EQ1, Q=0.7 for running MCACC. Simply leave it in two ports open, EQ2, Q=0.3 for the auto calibration. As far as I know, MCACC does not apply equalization in the bass.

Thank you. I ordered the sub and it will be here on Wednesday.

When you run your Advanced MCACC and the standing wave measurements you will yield 3 freqs it will fix. My situation has these that it recognized and fixed with 2 of the 3 being within my sub range. My problem freqs were 63hz, 74hz, and 96hz. Now with a crossover set at 80hz, 2 of these standing wave fixes were within the sub signal verified with adjustable Q values and freq adjustment all within the receiver. My listening distance to my ear canals is 14 feet for my subs. Fwiw, I love my Advanced MCACC and now have over 60 hrs experimenting, adjusting, and multi point testing.

Reference: Elite VSX 30

Good to know! I have always used their non-Elite models and those do not have any low frequency corrections.

Yes, Advanced MCACC and THX Select 2 processing and certification. You friend have a solid receiver. Mine does not have the THX processing, sucks for me!

With your on screen menus you should access the pro EQ thru the manual selection. When it comes to the correction point it should ask if you will be measuring multi point standing waves, select yes with the last point being your listening position. This is completely different from the multi point measures if you sit in multiple seats which in my case allows up to 6 different presets. The multi point measurement is by far one of the greatest things within a room correction. You will need to choose your processing delay as well and mine has the following choices to process: 0-20ms, 20-40ms, 30-50ms, 50-80ms, 80-120ms. I can suggest the 20-40ms for extreme resolution and clarity with a listening distance of the mains being 12 feet or so and subs being 14 feet to main listening position. The 30-50ms is also sufficient for said listening distance. Advanced MCACC allows a reverb measurement seperately which really is the same as the multi standing wave measures. With the reverb measure also multi point you will see on screen the response and if you download the program from Pioneer site you can save your results to flash drive and view your results with every bit of acoustical information for PC viewing in 3D or 2D. All this is exactly why I chose a Elite receiver, so much to explore!
