New HSU VTF-3 H.O. Specs (1 Viewer)

[Jack Gilvey]

Tuning to 13Hz will greatly increase excursion in the more important areas around 16-20Hz, certainly you'll lose quite a bit of headroom for a pedal that doesn't exist (?). 18Hz makes more sense when you actually think about it.
Also, that's a big "if". You shouldn't expect a "single 1220s output" (not sure what frequency you mean, but anywhere in its bandwidth) at 13Hz. The porting, excursion, and power requirements go up greatly as you go lower.

 

[Jack Gilvey]

Yes, it might. Any idea on cost or actual dimensions with and without the port extension?

 

[CurtisSC]

Jack....I don't have the dimensions or costs.

I think you saw the pictures I posted that compared the VTF-3HO with the VTF-3MK2. I think that gives a good idea of the size.

I still haven't seen the actual "turbocharger".....just descriptions.

Here are the pictures I have from the Hsu Research room at CES 2005.

Thanks Jack and Edward for that tuning point info. I will call Dr Hsu when he is back and ask his opinion as he is the only one to have spent time with it.

We do know this about the HSU Turbo:

No turbo-lag and no premium fuel required.

Also, you could make the argument that the mileage of the HO will be improved by the gas(es) moving through the turbo porting. The thing to remember is that subwoofer mileage is the inverse of other mileage. In this case going from 18 to 13 is an improvement.

There might also be some savings on house cooling with all that air moving through that turbo.

Perhaps the next big product announcement from Hsu will be the VTF-3 HMO? :wink:

 

[Craig Chase]

KenWA ... Man, THAT was BAD !!! ...

 

[Zack_R]

It sounds like you more or less heard a VTF-3?

 

[CurtisSC]

I own an older VTF-3.

At the show, I heard the prototype VTF-3HO which had the VTF-3MK2 driver and amp.

And if it makes a difference...I heard the black one.

 

[Chris Quinn]

The one he heard had the new box and ports.

 

[Jack Gilvey]

Thanks, Curtis. I didn't realize that was a comparison pic between the two models.

 

[Chris Quinn]

Is this the picture you are referring to?

 

[CurtisSC]

Nope....that is the VTF-2HO and VTF-2MK.
