That is how i have my dual HO's.

You would be better off adding a MBM-12 to the mix.

Well, after a long, arduous and brain racking journey, I just placed an order for a VTF-2 Mk3 this morning.

I've been debating whether to go for a MFW-15, but decided I just couldn't stand to be subless for the long wait, and including shipping the VTF-2 is $150 less than the MFW.

It may be a bit of a compromise, but my room is quite small (12'x10.5'x8' or just over 1000 sq ft) and this is for a 75% music set-up. I'm sure the Hsu will still give me PLENTY of headroom, right? I never play anything close to reference level. Maybe a bit over 100dB peaks when no one's around.

I'm VERY excited actually!

I'm guessing with my room size and listening preferences, Max Extension mode would be better? I'm only worried about potential chuffing with just a single port open. Anyone experience this? Also, what's the minimum distance from the back wall the sub should be to give the rear port(s) enough breathing room?

Thanks everyone.

edit: Also, what is the wait/shipping time like?

Hey guys, I talked to Hsu today regarding a different issue and just happened to ask him what he new about the new sub coming out.

What he said (and I am not endorsing this or saying this is def true or anything, just relaying information he said to me:

Price was in flux, would be firmed up within 1-1.5 months.

Expected in room freq response was flat to 10-12hz.

(incredulously he added) But the extension will not come at the expense of midbass impact (such as the turbo now does, i assume he meant)


That last part was crazy. So we might have in a month or two a sub that offers what the 3.3 does in MO mode AND flat extensino to 10hz. I basically dropped a hint that "soooo i shouldnt get a mbm12 now, right" and while he didnt comfirm or deny anything, he made it seem like waiting might be a good idea....

Whadda ya think??

Congrats! Yes the VTF MK2.3 is going to be killer in a room that size. You'll have to back-to-back test them, but in my experience the headroom lost to port chuffing (loud extremely low bass moves an unbelievable amount of air) does not justify the extra extension. Again, you'll have to see with your room size though.

The wait was like 1-2 days IIRC. Shipping time is standard ground shipping time to your location from Ca. I think it was 4 days for me.

You may be right. Max Output mode might be better, even with music, but I'll have to do some comparisons either way. I should get a good amount of room gain in the low frequencies anyway.

And I'm just up the coast in Oregon, so I suspect I'll be seeing this guy around the mid of next week. Can't wait! It's going to make finishing all my work before finals a little harder... oh well!

Does anyone have a similar setup. I have dual 3.3 without turbo in opposite corners with a MBM-12 near field. Currently I am running the dual 3.3 in max. output. Would it be better to run the dual 3.3 in max ext. without the turbos?
Now that I have a MBM-12 is it better running the subs in max ext rather than max output.

I read somewhere in this thread that your setup should be in Max Extention mode with one port plugged up, and allowing the MBM-12 to handle the high end stuff.

VTF-mk3, or VTF-1 paired with bookshelves with a frequency response down to 75Hz. Will they pair well? will I be giving too much midbass to the sub? will there be a smooth sound through-out the midbass and low bass range? I know the crossover on the sub only goes up to 90Hz. Does the low end of the sub suffer with higher crossovers? When you cross over is there any overlap in frequencies between the loudspeakers and the sub, or is it pretty well defined? What is the upper limit of the frequency range on the subs mentioned? thanks, noob questions I know. By the way, I care more about tight accurate bass for music than strong bass for HT.

I have dual HO's and an MBM and I have 1 in max output and 1 in max extension. Using REQ, I found this works best in my room.

If you don't have REQ (room eq wizard) I suggest you get it (free download) so you can see which configuration works best in your room.

The great thing about REQ is that it only takes about 10 secs to see how any changes you make affect your system.

Good luck

Just out of curiosity, aside from upgrading the plate amp, are there any upgrades I can do to my 1st gen VTF- 3? I would not consider switching, as they no longer make rosewood (which I can't believe!)

Huge difference. Place it near field.

The space in my living room is very limited at this point. The 2.3 sits to the right of the couch, end table position. The only spot I'll be able to place the MBM is directly behing the couch. So they'll be about 5'-6' apart. I looked on the HSU diagram and they recommend that the subwoofer be placed in the front corner but my setup doesn't allow for that.

Here's a couple pics. Any placement suggestions are appreciated

I would say place the 2.3 on the right side, in front or away from the front speaker, and place the MBM-12 behind the couch.

There's about 8" of space on either side of the front speakers. On the right side are drawers that slide out, if I were to place the 2.3 there they would be blocked. Hmm...I have about 3-4 days until it gets here to figure this out.

Then I guess it wouldn't hurt to place the 2.3 on the side of the sofa and the MBM-12 behind it. Is there a wall on the right side past the drawers? You could place it there.

With my AscendAcoustics CBM 170s and CMT 340 Center.... and my HSU VTF-3 MK3.... what would the best option be for me on cross over settings for the speakers, so that the sub is working with what it should be? It is currently at 80

Yes it goes drawers, mini-ledge, fireplace..so anything placed on that side would basically be sitting in the "middle" of the living room. What you mentioned is what I want to do, which is keep the sub where it is and place the MBM behind me. Just hope them being closer together than recommended doesn't negatively impact the acoustics.

If you don't mind the 2.3's back facing you, you could put it on the front left behind that speaker. Or just place it next to any wall.

Went ahead and took your advice. Put the dual 3.3 in max. ext. with one portplugged and the MBM-12 nearfield. I would have to say the bass sounds alot better on this mode. Thanks!! Still thinking about adding the turbos.
