So I am trying to improve the WAF of my space. The one thing left, according to the Squaw, if the giant black box in the room - the HSU VTF-15.

I was trying to find a smaller footprine sub that could give acceptable(or even better?) performance to the HSU, and came across the Paradigm seismic 110.

Does the group have any opinions of how the Seismic would compare to the VTF-15h, and also any other suggestions for high waf subs?

as always, thanks -

MK

You will definitely lose performance. It will be very hard not to going from a large enclosure to a small one. I don't think a Seismic 112 will measure up at all. I would go for a SVS SB13 Ultra or a ULS-15 or a Rythmik F15HP or E15. Still none of those will give you the VTF15h's output from around its tuning point.

Seismic 110:
- 10" high-excursion driver
- 850W RMS / 1,700W peak
- 18 Hz (DIN) extension
- 13.5" (h) × 13.75" (w) × 12.5625" (d)

You don't list size restrictions or a budget, so I'll suggest piano black version of:
- JL Fathom f113
- SVS SB13-Ultra
- Rythmik F15HP

Or a rosenut HSU ULS-15.

Or a red- or black-stained Funk Audio 18.0C.

I'd say budget around $1500.

Size restrictions is tough to say - there's no defined biggest size. All I can say is that it needs to be smaller and more WAF friendly than the VTF

Pretty big....about 40x20 with 8-10 ft ceilings. It's pretty enclosed though - their a staircase that enters into the area, and that's the only opening.

I wouldnt change the sub. The HSU you mentioned is a great sub. going to anything smaller is just going to be a downgrade. I would try and explain that the HSU is a compromise already. A room that size really should should have 4 subs if not more plus the staircase being open adds more volume. Pitch that and see what kind of response you get. Otherwise the most comparable are going to be the svs sb13, or JL audio subs. The JL's are around $4000. Or better yet, show her a paradigm sub 2 lol.

TC, someone has to tell you this and I see most couldn't bring themselves to do it so I will.

I need for you to grow a pair. Not to offend but as the above poster stated, that space you have really needs about 4 subs to do it justice in the bass department. Having one 15H isn't really enough for that space. I need for you to take a stand and explain why you need to keep the sub and not back down from it. There's no point in having a system if you're going to neuter it.

Sorry, but I had to show a little tough love.

He might still be able to get a halfway decent sound with a single sealed sub. If you can get a acceptable response with a single sub, he can still get some good bass above 30 Hz or so with a sealed. His system can still sound good, it will lose a lot of low end but could still prove to be nice and punchy with a good sealed sub. After all, his wife has to share his living room with him too. He can just movie his VTF15h to his 'man cave' or whatever.

Big area with room dimensions that would benefit from multiple subs.

Yeah, I've been told is multiple subs would be needed - never going to happen though.

The thing is, I'm more than happy with what the HSU gives me in this space. I've never measured, and I know I'm missing something, but I think in this case ignorance is bliss.

You don't want multiple subs and I can respect that but you have the 15H for a reason. I won't try to impose on how your household runs but I think your wife will respect you for taking a stand where you are. My wife has told me several times that she hates it when I'm not firm on decisions....ones she agrees with and those she may not.

I guess I should have specified-it's not a hard and fast WAF opinion that the HSU *has* to go. It's more of a "is there a smaller option available".

If I poke around and don't find anything - oh well.

I just thought - on paper - the paradigm looked like a win-win

Ok, understood. I hope you find something that works just as well in a smaller form factor.

Little late here, but I have a VTF-15 and 2 Seismic 110's. The VTF-15 is definitely more potent than a single Seismic 110. The Paradigm is amazing for what it is (tiny), but you could fit 4 of them inside a single VTF-15. I use the 110's in my office and kitchen systems. The kitchen didn't have a sub previously and required a small sub for WAF, and in the office the Seismic replaced an HSU VTF-3 MK III (can you say overkill?) which had previously replaced a VTF-1. For 2-channel and gaming in the office I don't feel like I lost anything, and if anything the bass tightened up a little with the PBK, but in the HT I would only consider replacing the VTF-15 with the pair of 110's, and in that case I would want to have a good listen before making the change final. I was originally planning to buy just a single 110, but the seller had 2 of them and the price was right. I sold the VTF-3 for $100 less than I paid for the 110 for the office, but I'm in Canada and the cost of shipping a big HSU here is about $400.
