+1 more.

All we know at this point - the MBM-12 unit has the 12 inch driver. The word from T.H.E. Show is that HSU reps were keeping a tight lip on the new prototype and there were not very happy with those attempting to take a picture. The prototypes were in the back of the room and not easily visible/accessible.

My guess is that Dr. Hsu finally has come up with a design using a driver bigger than 12".

Now that would be nice. I guess we will wait and see.

Agree...

You can only take a 12" driver design so far.
post #35 of 2029
So, how are you supposed to clearly 'hear' 16hz sounds? That is below the range of the human ear. haha. Obviously they could be felt, but I don't understand how you could make the former claim.

+1. SVS realized that and now their Ultra 13 is kicking some serious ass.

Remember its a prototype at a show. When/if its released the critics will have plenty of time to confirm or deny its performance. Dr Hsu is always looking at innovative ways to bring affordable performance sound into your system. Certainly Dr Hsu is not the type of guy to BS by making glossy sexed up spec sheets.

Maybe those boxes were for turbocharger ports coming out of the floor! (or those were were just pictures of MBMs and no pics of the 10hz subs are out yet).

Common misconception....you can hear below 20 Hz, the amplitude required is very high though.

I think 20-20k is the "common" human hearing range but it varies between particular indivuals and is affected by age too. Some might hear 16-30k or something like that, but I doubt anyone can hear 10hz
Oh, and there's a certain low frequency range that makes people panic when they "feel" it, isnt there?

True, then Tom Danley invented the dts-20

I think it would be nice to see some bigger drivers from these manufacturers like SVS, JL and HSU

That enclosure was also huge and a folded horn.

Ya I woiuld mind seeing what SVS / HSU could do with a pair of stout 15's.

LOL! True, trueand a 12" with only 13mm xmax to boot.

I'm gonna guess that the new HSU is a 15" PR system. That would be so unlike them though...
post #44 of 2029
If it's flat to 10Hz then the -3dB point should be about 7-8Hz right

i believe he said "heard and felt" if you're referring to post #1

when you step on a 32' pedal stop of a pipe organ which is 16hz if it's the lowest note of a 32' rank, you can both feel the fundamental tone and hear the upper harmonics of the note

it also depends on the "type" of 32' rank you're talking about (Contra Bourdon 32, Contra Principal 32, Contra Violone 32, Contra Bombarde 32 etc.)

some have a lot of fundamental and very little harmonic development, some have both fundamental and good harmonic development, some have little fundamental and plenty of harmonics

and some like the loud reeds (Contra Bombarde 32) with plenty of building-shaking fundamental and plenty of harmonics, both in tune and out of tune

technically, if you're sitting in an anechoic chamber with a 16hz sine wave playing, chances are you will "hear" nothing

but organ pipes are a bit different

*some of the rank info copied from this site:

I used "hear" in a general sense and certainly the palpable feeling is a big part of it. Perhaps I should have said that the 16Hz pedal stops were clearly perceptible.

Regardless, living in LV, I go to CES most years. I've also been to the Rocky Mountain show a couple of times. And I've never heard -or felt - anything like this...

John, were you able to pry any more info out of the Hsu guys or get a better look?
post #48 of 2029
when is the info going to be released? They wouldn't bring it if they did not want to show it off.

We have no idea as I already said HSU been going in a very well interesting direction lately and there marketing has been rather nonexistent.

Sorry Curtis, but no. They allowed the one quick picture of the front and, since it was all against the back wall with chairs in front of it, I couldn't see much more than that. There were 3 cabinets, one MBM and the 2 subs. Each sub cabinet was quite large, about the same size as the VTF-3, and longer than it was deep. The room was very dark so it was hard to see more.

I have a lot of respect for Dr. Hsu, so when he said "I'm not ready to discuss it", I took him at his word ...

See this makes no sense don't bring something your not ready to talk about plane and simple. I'm sorry if that sounds rude but this is a show about getting new product out its not like somoone came to the HSU shop and saw it. I don't know its just odd.
post #52 of 2029
if they're not ready to give a tiny amount of info ... IMO, they should not have brought it to CES.
post #53 of 2029
All of you people that are getting all excited and want to buy one yesterday, calm down. They'll release it when they release it.
post #54 of 2029
Lanion on the Hsu forum mentioned the idea that this could be a unit designed to go from 10hz to 50Hz, and is meant, if not required-ish to operate with an MBM-12 to cover the full LFE range. Interesting idea.

Personally, I find that supposition plausible, given the described size of the unit (in the range of the vtf-3, but a little deeper).

Hsu has our interest now, so easily, don't they? Listen to us chittering and already beginning to argue too funny.

Thanks John.

I think it is fair that Dr. Hsu wanted to use this venue to demonstrate its capabilities, but does not want to talk about what's inside.

Well, they told us it's flat to 10Hz. Isn't that an important piece of info ?

Believe me, at these shows companies show prototypes all the time, spanning all stages of development. There's nothing out of the ordinary going on here - Samsung exhibited an ICE- powered mega-receiver for 3 years in a row that (AFAIK) never made it to market...

I went to there room at the St Tropez and they walked us through a demo with various music and movies, I must say the bass and speaker package from there prototypes were impressive through the spectrum of music and video. Not to mention that they were super polite and eager to see our impressions of it...and talking with Dr. HSU was a pleasure , also ordered a couple of VTF-3 HO's for our homes, kudos the company for a dedicated effort producing these products for us.
post #58 of 2029
I hardly feel it's unreasonable for people to expect such info at a trade show, particularly when they posted an open invite on their website and indicated they would be debuting new products

not really, last time SVS brought along their "vaporware":

they brought in the driver of the 13Ultra
and
at least a lot of info regarding their new EQ.

they had brochures, let people take a lot of pics.

I don't see why they brought it to a public place and don't want people to see it. (or take pics)

they announce it, but it's a secret.

hype machine if you ask me.
post #60 of 2029
What if they gave you more info and then said they have no delivery date as of yet?

What did they actually announce? Nothing. So pretend it doesn't exist.
