Actually now that I am rereading the thread, I don't really think the Hsu's in themselves can give what eccoboy is after. To recap, eccoboy earlier stated:

The tower speakers with larger sealed enclosures holding 1 or more 7 or 8 inch woofers tend to give me that big sound that I like. Of course a properly placed subwoofer paired with smaller speakers can sound big too. I don't get to hear different speaker setups too often and I certainly can't think of any specific examples. This is just what I have experienced.

I think the HB speakers can give you that as much as any other speaker, but you have to give them the proper room as much as any other speaker would need it. That "big sound" typically refers to effortless dynamics, and if properly dialed-in, these speakers can whoop your ass, so yes, they can sound big.
I suspected the room might be apart of the issue with his sound when he said the Ventriloquist got loud enough, but he still wanted a "bigger" sound. I will state a few thoughts on a "bigger" sound, a word you hear a lot here, and what it might mean.
I think what is meant by "big" in relation to sound is dynamics, and especially bass. Think about "big" and bass for a minute here. Only "big" things produce bass in life, like earthquakes and thunder and freight trains. Big speakers do it to (though not always). You can't have a "big" sound without serious bass, and eccoboy, your sub is meant for small rooms.
Another thing about "big" sound is room acoustics; a big room sounds "big", usually due to a slight reverb. The main screens at commercial cinemas sound "big", even though they try to dampen the sound. Many receivers try to reproduce this effect with their DSPs in environment settings like "hall", "opera", "arena", etc. I think my Onkyo even has a "sci-fi" environment effect. Anyway it is difficult to recapture that effect in a smaller room, and the receiver DSP effects never quite actually do it, at least to my ears. Some people attempt to use big speakers in their room to achieve that particular sound, and you see this quite a bit here on AVSforum and elsewhere, but I think they don't quite realize it has a lot to do with their own room, not their speakers. If the room sounds small, no speaker, no matter how big, will change that, and no DSP setting can really make it sound bigger either; that room's sound signature is going to be there no matter what. One thing that can be done is to dampen the room to take it out of the equation as much as possible, that is, the room can't sound "small" if it isn't contributing to the sound at all.
To eccoboy, I think you might be contending with both your room and anemic bass.
For the room, see if using Hsu's recommended stand-off distances help: that should reduce acoustic reflection. Also, experiment with different toe-ins. Some people have preferred the sound with the toe-in crossing in front of them rather than right on the listening position, others seem to like the toe-in behind them. Also, try using the speaker with the grill off. Outside of that you will need to look into room treatments and acoustic dampening.
For serious bass, you could try placing your sub in different locations, many times that can dramatically increase the bass at listening position. However, there is only so much an STF1 can do. In the end, if you want a big sound, you are going to need a subwoofer with a much larger driver than a 8". If you really want a big sound, get two serious subs and place them near your left and right fronts. This helps a lot to defeat subwoofer localization, which can really contribute to a small sound.
Anyway, sorry for the long post, hopefully something in here can help. Also, if you let me know the size of your room, your distance from the speakers, and your subwoofer placement, I might be able to offer more specific advice. One thing I can say is that if you are sitting close to the speakers or are in a small room, you might try some speakers with dome tweeters, they can project a wider sound stage with more emphasis on highs and so perhaps a bigger sound in those circumstances than more directional horn-loaded speakers
