In general, is there a big difference among subwoofers in how well they produce the higher frequencies?

All of our subs are flat up to at least 200 Hz, more than enough for a subwoofer. 100 - 120 Hz is not an issue for our subs. The only issue with a high crossover is the sub tend to be a lot more localizable. You need to place it up front between the two main speakers, or directly behind you.

That's great to know! Thank you for your reply.

Just took a trip to the factory and picked up a Hybrid 3 2.1 system! Can't wait to set it up and hear it now!

Thanks to everybody at the Hsu factory for making this a great, easy pickup!

That is a great setup, I ran some HB-1s with a VTF3 for awhile- I hope you like to rock because you got some rockin' speakers.

ordered a vtf-2 mk4 this morn. my first "real" sub lol & can hardly wait for it to arrive!! home audio is a great hobby even for those of us on a budget. currently using a bic f12 as i really had no clue what i was buying or why a year ago. since then, i researched subs til i was blue in the face & am confident i made the right choice. thx dr hsu & avsforum & will post again when i get it all set up.

I have 2 older VTF-3's that I believe are almost identical to the VTF-2 mk4. I can safely say that you will be thrilled!

Seth,
did you give the sub a break in time?. i'm asking is because they do need to be breaking in and get loosing up etc. that's a great sub btw you'll be happy with it

How long is the break in period?

I would say at least a week of bass heavy music at moderate to loud levels should do the trick.

got my new vtf2-mk4 yesterday, was like a lil kid on christmas morn lol, so much to my chagrin when i discovered a bad nick:eek: on the right front corner when i pushed the plastic back sigh. so new sub is going back today & hopefully another will get shipped today, if not tomorrow then. good things come to those who wait huh hehe. box looks like a blade from a forklift went thru it perhaps, hard to say i guess, even tho the corners are double boxed!! shame on fedex! first time i've ever had a prob so guess it was bound to happen sooner or later...cool.gif

i realize it's not the company's (yours) fault but fedex, was just soooo disappointed that i didn't even get to hear it or use it after all the anticipation lol, but like i said, things do happen even tho this sub was/is extremely well packaged with reinforced corners even, just watch the news lol. so maybe by next mon or tues i'll be able to tout the virtues of my new listening environment since fedex picked up the damaged sub this morn & i called hsu research & let them know so hopefully the replacement can go out today!!rolleyes.gif
post #5355 of 6210
the waiting is the hardest part lol, but at least the new sub is en route, should get here monday. funny how a little piece of equipment can bring about this level of anticipation!! biggrin.gif
post #5356 of 6210
Guys, I had a separated thread about this and think it is probably best to ask here. Hopefully i can get some guidance here from you guys and Dr. Hsu.
I am currently running a Hsu vtf2.3 in my dedicated theater room about 2700' ^3 (14x19 with 10' ceiling) used 100% for movies. I like this sub a lot. The more I am reading here has made me thinking about making it even better. Should I get a vtf2.4 and run it with the older version vtf2.3 i have in a dual subs configuration (any problem mismatch two different versions of the same sub here?)? Or should I just get the vtf15 and use it singlely without my vtf2.3? Or should I add the vtf15 to my vtf2.3 for dual subs (again any mismatch problem here?)? I am using the Denon 3312 as receiver. All sub will be placed in front of the room between the front L/R speakers (WAF- no other option here). What would you do? Thanks.

Looking forward to getting new equipment is always exciting. biggrin.gif

Would an HSU STF-1 have about the same performance as an Outlaw M8? Both are around the same price (Outlaw slightly less) but the M8 is ported on the bottom rather than the rear. Has anyone matched these up and put them to the test?
post #5359 of 6210
I do not know much about the M8 as that is not a Hsu designed sub.
post #5360 of 6210
Other than the amp power and twin port design, are there any other differences between the STF-2 and VTF-1 MK2?

The VTF (Variable Tuning Frequency) allows a user to choose various operating modes and compromises to suit his or her goals.

The woofer on the VTF-1 has a larger magnet as well.
post #5363 of 6210
A larger magnet means the voice coil would need less energy to propel itself against the magnetic field, is that correct? So, everything else being equal, a driver with a larger magnet ought to have greater excursion?
post #5364 of 6210
What would you guys choose? I have the Paradigm DSP-3400 and 3200 but selling the 3200... My room is about 3000 cubic feet and its mostly for movies with gaming and some music!.....I like dual subs but I know your not supposed to mismatch subs and why I am curious on the selections. I want something that will last a very long time!

1 - Buy a SVS PB13-Ultra up front with the 3400 in the back = around $2000
2 - sell both 3400,3200 and get 2 SVS PB12-Plus's = about $3000
3 - Sell both and get 2 HSU VTF-15H's = give or take $2600-$2800 since I live in Canada

Question - Would 1 SVS PB13-Ultra beat out 2 HSU VTF-15H's?????

Option 3 and no to your last question or at least by my math collocated.

Would two VTF-1 units have more punch vs a single VTF-2? Is there a "break in" period for any of these units in the beginning?

The larger magnet in this case means lower driver Q, tighter bass, even more so if you turn down the Q on the VTF-1 MK2 amp.

Two VTF-1 MK2 should have more mid bass output than one VTF-2 MK4, but does not have the same bass extension. How much more mid bass output also depends on where you place the two VTF-1s. You can place them to get more even bass distribution but no higher headroom or place them to get maximum headroom increase, but not much change in bass distribution.

Stylz, this is just speculation, but I think that a PB13 would have stronger deep bass, and two VTF15hs would have better frequency response and more even room response. Two subs would do be much less localizable as well, as long as you don't place them right next to each other. There are pros and cons to each option.

The PB-13 will have to be incredibly powerful to have stronger low bass output than two 15Hs. First, two 15Hs will have more port cross sectional area than the PB-13. Second efficiency would be much higher since two 15Hs will have much larger total enclosure volume.
