More powerful STF offering?

[aps1ngh]

I noticed that the STF-3 12 inch subwoofer was a past offering of the HSU research line. I am very interested in purchasing a HSU research subwoofer but I would like a 12 inch subwoofer that extends as low as the VTF-2 MK 3 without the variable tuning circuitry. I also believe the STF-2 to be inadequate for my setup. Is there any intention to bring back a more powerful, deeper extending, 12 inch STF subwoofer?

Is there any particular reason why you wouldn't prefer the VTF-2 Mk. 3?

There's no need for the STF-3 anymore. The VTF-2 Mk. 3 is a much better subwoofer at the same price as the STF-3, if it was still one sale. The STF-3 only extends down to 25 Hz whereas the the VTF-2 Mk. 3 goes to 18 Hz in ME mode. The VTF-2 Mk. 3 has a better driver as well. In the sub world, bigger amp does not mean better. It's all about efficiency and design. Thus, Dr. Hsu is wise to discontinue the STF-3.

Essentially I was assuming that a newer STF-3 variant would use the VTF-2 mk. 3 driver and amp locked in ME mode much like the STF-2 does for the VTF-1.

What I was trying to say in my initial post, but failed to articulate properly, is that I would love to see an updated STF-3 (an STF-3 mk. 2 if I may) which gives us the locked ME extension of the VTF-2 mk. 3 without the variable tuning circuitry and at a lower price (much like the STF-2 is to the VTF-1). Are there any plans for such a subwoofer because I feel like that would help diversify HSU's subwoofer line and I would be first in line for such a sub given my budget and my needs.

Personally i think the 2.3 is worth the price even if you don't use variable tuning. It one hell of a sub at that price point imo. Plus i dont think a little drop in price to meet a few customers needs justifies designing a new sub.

If that's the case, then why design the STF-2 as a single tuned VTF-1? It's $100 less expensive (which is quite significant). It's not like it's a major design overhaul especially since they would be putting a more simple amplifier (one I'm sure they already have the production plans on considering the sheer amount of research they probably do when developing new products) on the same subwoofer driver.

Second, I'm not arguing that the 2.3 isn't a great sub for its price point. In fact I'm sure it's an absolutely fantastic sub for its price point. That doesn't change the fact that its not offered in a less expensive STF variant. I've read a lot about Dr. Hsu and his philopsophy of offering the best sound quality for exceptional value to all consumers and I respect him all the more for it. It is for this reason that I am all the more puzzled that an upgraded STF-3 isn't a part of their product line.

But I didn't create this post to get into arguments about Dr. Hsu' business/marketing strategy or even criticize a man or a company that I respect very much. All I am asking is whether or not a sub of this type is going to be offered by HSU Research anytime soon. I was hoping Pete would peruse this thread and could possibly give me an answer or that anyone else with some knowledge or insight into the matter could perhaps share it with us.

While the VTF-1 may be similar to the STF-2 as people mistakenly assumed, it is not. Pete kept insisted this fact, but no one seems to understand this. The VTF-1 uses a different driver (and heavier) in a better built cabinet. The VTF-1 has a flatter frequency response with bigger magnet. Thus, if you look at the specs of the VTF-1, it is 56 lbs (shipped weight of course) versus 44 lbs (shipped weight) for the STF-2. Given these facts, one would argue that the VTF-1's sound quality should be better objectively and subjectively.

Now, regarding the Variable Tuning feature, whether or not you use it, it may be beneficial in some environment. In addition, the premium finish with the VTF series is a plus for those who needs a more decor-friendly or WAF-friendly subwoofer.

I guess the bottom line is, if I understand you correctly, you would want a STF-3 for around $449 using a 12" driver with a 200 amp plate?

250 watt, but yes please. :p

I was actually quite unaware of all of this information. I appreciate you giving me this extra info. I was unaware of the flatter frequency response and the cabinet and driver differences. Again, this helps a lot. Thanks.

No problem! It took me some time to realize this fact, but when I heard somebody over AVS mention about the weight differences, I finally understood. I was planning to get one during the special sale, but waited out for the VTF-2 Mk. 3 sale instead.

For someone in a smaller size room, the VTF-1 could do quite well. Performance should be quite comparable to the SVS PB10-NSD with just a slight shorter bass extension and hence the similar pricing given. However, we are only speaking about output. Quality-wise, the VTF-1 should sound better as well as the fact that the VTF-1 has a better finish even in satin black versus the standard matte finish on the PB10.

Hi aps1ngh,

I do see what you are saying. Just as we have a lower cost alternative to VTF-1 (which is the STF-2), you would like to see a lower cost alternative to the VTF-2 MK3 (which would be in the form of a new STF-3). Unfortunately I don't think this will happen, because this hypothetical new STF-3 would be so close in price to the VTF-2 MK3 when it's on sale, and so close in price to the VTF-1 regular price.

Sincerely,
