Right now I have an hsu VTF-3 MK3 without a super charger and have paradigm studio 60 v3's coming (which have good bass).

I am deciding on 3 different options each costing around $500

1. Add the super charger to the VTF3 and add an hsu MBM-12
2. Add a SVS PB12/2 (this would be the hardest to get and cost a bit over 500)
3. Add a paradigm ps-1000 AND a pdr-10

Right now I am unhappy with the mid bass of the vtf-3 alone and want more...

Right now I have an hsu VTF-3 MK3 without a sub......................Isn't the hsu VTF-3 MK3 a sub?

Right now I am unhappy with the mid bass of the vtf-3 alone and want more...How have you set it up, particularly the crossover and room arrangement? Why are you not waiting to see what the Studio60s will do?

Honestly my vtf3-mk3 has been nothing but a hunk of junk...

At anything over 50hz at a loud volume (like movie watching!) it will make a VIOLENT flapping sound. Dr. Hsu had me test the woofer and it seemed ok so he is taking the amp back to look at it... If it doesn't improve I definetly need to add something to handle from 40hz and up. it is still driving VERY low but thats all it can handle.

My solution is to add somethign else to handle most frequencies because if there is no fix to the problem then I may as well let it do what it can do best and fix the problem with another sub.

The studio 60's will most likely be set to "full band" and let the subs double the bass frequencies (reciever setting)

I am still new to all of this so feel free to correct me in any and every way.

I have no idea what your expectations are, what your room is like or how you have it hooked up. However, it seems as if you are very demanding about bass and mid-bass levels.

If so, I would not run the Studio60s full-range (I have 3 of them in one of my systems) but cross over to the sub at 50-60Hz. This will prevent overloading the Paradigms on big LF signals and will let your (new) sub handle the load. If this ain't enough, raise the crossover to 80Hz.

Also, make sure you have properly set-up, configured and calibrated your system using all the tools in your (un-named) electronics.

I picked up a MBM-12 used for cheap so I'll give it a shot... So far my VTF has been a nightmare that distrorts with horrible flapping noises I have never heard from any sub before at anything over 45hz...

It just sucks to set the crossover to 80hz because then the MBM will only handle 80-50, and the vtf only 45-18...

I guess once I get it back from HSU I will work with them to get it fixed. I hear so much great stuff about the vtf and mbm I just want to expereince it!

Oh and I am using an onlyo 805 which fdr hsu himself should be fine...

I'd say the sub is calibrated incorrectly, or there is something wrong with the sub.

As a former VTF3.3 owner, I must say something is wrong here. :confused::confused: How are you running your 3.3? Do you have it set to MAX Output OR Max Extension mode? I have owned everything from the Mirage S12 to the SVS PB10-NSD to the PB12-NSD. Then, later I opted for the VTF3 MKIII and currently own dual Outlaw Audio LFM-1Pluses. Out of all of these, the 3.3 was the best imho. ;);) I only ran my 3.3 in Max Output mode meaning no ports plugged. Likewise, the same holds true for my LFM-1Pluses. My advice is to talk directly with Dr. Hsu and narrow it down step by step until you both find some sort of a solution. My guess is, you have something set wrong somewhere. If not, then the sub is defective. None of my subs ever did what you are describing. Hope this helps and good luck in ascertaining a solution to your dilemma.

Cheers,

What are your room dimensions, where is your listening position situated (in terms of the room's length dimension), and where is the subwoofer located. Is the bass stronger elsewhere in the room? If so, it is possible you are sitting in a null and you just need to move your chair. It is also likely you may have to move your subwoofer to a more acoustically optimal location.

... and post up your Audyssey settings, particularly sub level. Bear in mind that there have been issues with this particular AVR's Audyssey function...

How much gain on your 3.3 dial?

Something is wrong with your setup or the sub as it will rock you out of your chair I have two and believe me its SCARY!!!!!!!!!!!!!!!!!! :D

That's about as good as saying I have 500 horsepower, but not disclosing if it's in a highway truck that is hauling 70 tons or in a 3,000 pound car.

Maybe the original poster has a 7,000 cu foot room, and you have a 2,000 cu ft room? Who really knows. Need more info!
