Hi Brian,

I would prepare to ship the woofer to us so that we can take a look, as this is almost certainly the advice that you would get from techsupport. You can call sometime tomorrow morning to get an RMA number to write on the box, and then send it over as soon as you can.

Sincerely,

Pete - Hsu Research

So in order to remove the driver do I need to take off the amp plate as well? I took all the screws out of the driver but can't seem to get it out as it is lodged in very well.

Any suggestions?

What set up would you guys try first or think would work best according to sub placement of my VFT-MK3
To the left is a corner. Center is mounted on top of TV. And I have a gamma pad.
The TV can be positioned proportionally to the speakers as this graph is off somewhat.
Though I would prefer choice A.
Thanks so much

Actually I have found that placing the sub 2 inches BEHIND the sofa, or next to it, with the sub firing into it, is the very best position.
Pete_Hsu advised me to do that, but I didn't until 2 weeks ago, and was stunned at the difference.
Max Extention mode with one port plugged (If you don't have the Turbo) will yield the best results.

It has to be in the front.

Usually it is easiest to remove the amp first (unscrew the perimeter screws), so that you can use the amp cutout to assist in supporting and lifting out the woofer.

Thanks Pete. That makes sense.

If anybody wants any pics of the internals or drivers I'll take some tonight after I've removed the plate.

Yes. And the personal customer service that goes along with it, such as Pete frequenting these forums, also goes a long way.

I have been on the fence as to which way to go for a sub and I'm almost 100% sure it will be a Hsu. I just need to decide which model?

I am looking for a low-end that suits music audio rather than HT, although I will be using it for both.

Well if music is your main goal, then HSU is your best bet.

There is a complete writeup about the build quality of HSU subs on Audioholics. They gutted one out and discussed it here: http://www.audioholics.com/reviews/s...-build-quality

Based on those pictures and the description of the problem Brian it looks like the driver may be hitting the port for some reason.

No, I don't think that is it. The ports are well out of the way of the driver, even though it may not appear that way in the pictures. Also note that those are pictures of the VTF-3 MK3.

I will be buying an MBM-12 really soon and I have a few questions.

1) I prefer the nearfield placement of my 3.3 with Turbo, can I place the MBM at the front left position instead?

2) What setting should I use for both on the subs?

3) Should I maintain my 80Hz crossover setting in my Onkyo 705?

From my understanding because the lower frequency bass waves are bigger they are better experienced when the sub is not nearfield and the opposite is true of the mid bass thus you're better off with the MBM nearfield and the 3.3 with turbo in the front left spot.

You will have to adjust the gain individually but first set the crossover on the 3.3 to 50 which is where the MBM naturally rolls off. The gain settings will be based on your individual needs and best measured with test tones and a SPL meter or something like Room EQ wizard.

Depending on where your MBM is put you may find you can localize it if you cross over higher than 80 but if you can't localize it you can set a higher crossover. The MBM is very capable at least up to 150 hz. The benefit of setting it higher depends really on what kind of main speakers you're running but you will be stressing your mains and Onkyo less if the MBM is handling more. From everything I have read the MBM is very capable.

I wish I had a wife who would accept me having 4 subwoofers simulaneously then I could have compared 2 MFW-15s to a VTF-3 HO + MBM but I don't.

Agh! So the amp plate is out, positive and negative disconnected, screws that hold the driver in place from the exterior out and it is still stuck in the beast like the sword in the stone!!

Maybe I'll pm that guy from audioholics!

Any pics I'd take would look the same as above by BluLove aside from the driver is different.

I run two MBM-12's (farfield), one with each main and a 3.3 Turbo (nearfield) behind the seating area. The bass is like WOW!

Is there a wall or partial wall on the left side? I ask because you don't want to put speakers where there is a wall close (closer than 2-3 feet) on the side due to reflections. At least ideally.

So my instinct would be to put the sub on the left, then the speaker. But you can always experiment with some bass-y music, test tones, etc. to see which spot gives you better (read: smoother, less peaks) bass, before you even put the speaker there.

Blu, could you do me a favor and describe your room for me again (including room dimensions)? Is your VTF sub placed sideways behind the couch right now?

Generally, it is best to place MBM either in the nearfield, or flanking L/R front speakers. Some people prefer it one way, some the other way, although flanking L/R front speakers would tend to work best using two MBM. So I would suggest trying some different locations to see what works best for you.

Yes, if the MBM is in the nearfield, you should use an 80Hz crossover setting on the receiver. Set the MBM crossover switch to 'Out', and set the VTF crossover switch to 'In' with crossover knob at 50Hz. Feel free to experiment with inverting the phase on the MBM to see if it makes any difference.

Assuming that the front left corner in your drawing is an enclosed wall, then I would probably go with postion A.

Yes the left side is enclosed, and also my preferred set up. Gonna do that and call it a day.
Pete , got that gamma pad, it's cool and sweetwater,(where i got it) like HSU is awesome.
