Super Charger

[ThomasV]

Tell me about the super charger.

[lradden]

You mean the turbo?

[Pete_Hsu]

Good work Thomas! Not sure I want to say anything more though http://www.avsforum.com/avs-vb/images/smilies/smile.gif

FYI, Dr. Hsu originally had come up with a different way to do this, but I pointed out to him that there was a problem if one wanted to keep the height in check, so within a few hours at night he emailed me about a major breakthrough alternate approach that he had come up with that solved all the issues associated with the original idea.

For those who are confused where the reference came from, see this video interview just posted at www.hometheaterhifi.com (http://www.hometheaterhifi.com) .

[lradden]

Ah now I undrstand! OK so when will we hear more details?

[Pete_Hsu]

I'm not sure, my friend...stay [variably] tuned :)

[lradden]

Darn it was worth a try. Of course you know I'll buy anything the Dr. makes. Let me try one more and see if you'll bite. Will the supercharger fit a MKII or HO?

[Pete_Hsu]

Legairre, let's see if I can point you in the right direction: going over the description that was given by Dr. Hsu, is there a reason why this would only fit the HO? :)

[lradden]

The Dr. is just, crazy, crazy I say :D.

[Pete_Hsu]

Yes, I agree, crazy in a good ingenius type of way though :D

[Pete_Hsu]

Here's one more hint, Legairre: did Dr. Hsu mention anything about turbocharger and supercharger necessarily being mutually exclusive? :)

[BradJudy]

is there a reason why this would only fit the HO? :)

I don't this reference Peter, I can think of multiple reasons:

they use different amps that might have different cut-outs

the amps are different heights off the ground since one is downward firing and one isn't

they have different drivers, tuning frequencies and enclosure volumes that would react differently to expanding the enclosure volume

Personally, I would be rather surprised if the same enclosure expansion could effectively be used on either sub.

[Pete_Hsu]

That's not what I meant, Brad. My point was: is there any reason why there can't be a supercharger for the Mk2 series? :)

[BradJudy]

That's not what I meant, Brad. My point was: is there any reason why there can't be a supercharger for the Mk2 series? :)

When phrased that way, no there's no reason why you couldn't make one.

[lradden]

Here's one more hint, Legairre: did Dr. Hsu mention anything about turbocharger and supercharger necessarily being mutually exclusive? :)

Ah Peter, now you're just toying with me. Now that I think of it the good Dr. never said you had to use one or the other. Man it would just be so cool to be able to use the turbo and the super at the same time. Add in an MBM-12 and that's what I call a modular sub system. You aren't joking when you say upgrade your current sub versus buying a new one. :eek:

[Lwang]

So what do you want to know about the HSUpercharger?

[Pete_Hsu]

That's a Hsuper name for it :D

[ThomasV]

I get how it works, but anyone want to sketch what this thing may look like, an HO w/ HSUper and Turbo Charger.
I picture a pretty deep subwoofer.

[Pete_Hsu]

No sketch just yet, Thomas, but I will say that with supercharger, one will be able to either minimize depth (by turning the entire enclosure sideways and placing it along the front wall), minimize width (by placing it along the side wall), or minimize floorspace occupied (by placing it standing up). Also, the longest dimension need not be longer than a TN1220HO!

[JonnyOzero3]

Okay, I can't click the "subscribe" button fast enough. :)

I had always wondered what else was coming down the line after reading Secret's initial review which called the HO a "modular" subwoofer. This is interesting.

[BradJudy]

Well, I think Peter and the Dr have given enough information that one could draw some potential drawings. It's a box that attaches to the amp cut out - it's probably the same height and width of the HO (presumably in the same finish) and the total depth of the HO plus supercharger won't exceed 51" (HO is 25" deep). Peter has said it's smaller than the HO itself, but also notes 2x the air volume. If one was really motivated, one could calculate the volume of an HO, subtract the volume of the driver, amp and ports, and then you'd have the likely internal volume of the supercharger. Based on this, you could estimate the overall size.

I'm not going to attempt the actual math right now, but I'd guesstimate ~12-18" of extra depth to put a supercharger on a HO based on what we already know.

[Pete_Hsu]

Good way to break things down, Brad. While the height of the supercharger can be the same height as HO, it actually doesn't need to be. ;)

[BradJudy]

Ah yes, the ports are on the back above the amp, so you can't have the supercharger be as tall, otherwise it would obstruct the ports and not allow a turbocharger to be attached. That's too bad since it would look nicer if the supercharger was the same height.

Of course, there is a trick that can be done here (okay Peter, if the Dr hasn't already thought of this feel free to send me a nice discount for the idea). The turbocharger and supercharger can be built into the same box so that the result is a turbo-super-charger that is the same height as the HO and has a straight, rather than bent, port extension. The resulting box would look exactly like the HO from the back (allowing you to reuse the existing HO rear panel). It would be both more aesthetically pleasing as well as efficient than separate turbo and super for the HO. In fact, I don't see any reason to make a super that isn't also a turbo.

If the description is confusing, I'll diagram it tonight.

[Pete_Hsu]

Yes Brad, I've thought of that configuration too. The only issue is that it is debateable how useful it will be to use both turbocharger and supercharger at the same time, especially when using just a single subwoofer.

[JonnyOzero3]

So when are you coming out with an intercooler? :p

[BradJudy]

Yes Brad, I've thought of that configuration too.

Dang, no free discounts. :)

[Pete_Hsu]

Brad, about a year ago I emailed Dr. Hsu a picture similar to what you were describing above. :o

I really do appreciate all of the suggestions and constructive feedback though!

[lradden]

Peter any "guesstimate" on what kind of extention(Hz) a HO would have with a supercharger? Also would a HO play louder as well?

[majorloser]

Now I want to add superchargers to my order of two VT-3HO's.

[DrewB]

So the HO will have the option of adding boobs (the turbo) or ass (the supercharger)? :eek: :D

[Pete_Hsu]

Laughing out loud, that is one way to put it, although it may not make it into the brochure description :D

"Aftermarket accessories"

A Dolly Parton turbo and a J. Lo supercharger!

Subs do add more bottom end .......

[JonnyOzero3]

I'm not a fan of J. Lo's rear. I'd take Scarlett's, Sharipova's, or Jessica Alba's anyday over hers....

[davenlei]

How about an 'L' shaped HSUpercharger so it will fit nicely in the corner of the room.....

Make the HSUpercharger connection (opening) to the HO opening on the side of the charger unit so it will keep the overall setup from being really long.
