What subs do you think will pair up best? (1 Viewer)

Velodyne DD 18, Infinity Intermezzo 1.2s, and/or Def Tech SuperCube 1.
And please don't start with "It depends... "

Pair up with what?

It depends on the room, the speakers, your goals, your budget and your constraints. But out of the 3 you listed, I'd get something else. We are partial to internet direct subs as a best value.

With each other.

A quick search shows that the Infinities list for $1,800 each so along those prices, I'd go with:
SVS PB-13 Ultra
Epik Subwoofers Empire
Hsu Research ULS -15
Rythmik Audio FV-15
If you can DIY, you could use the same budget and go completely nuts.

I'm no sub expert (like Robert_J) but unless you're trying to deal with main speakers that have very inadequate mid-bass or are dealing with a very large room, I would rather get one good sub (or a pair of identical subs) than try to mix and match two different subs in a room.

One sub that reaches down to 20Hz plus another sub that reaches down to 20Hz won't magically combine to reach down to 15Hz. Using multiple subs can help with increased headroom and with reducing room nulls for a more even response, but again, IMO, that's easier to accomplish with two identical subs, rather than two different models.

Also, I know you didn't want to hear this, but "it depends" on your room geometry as well. There is no single "right" answer when it comes to speakers or subwoofers.

What Jason said. If you want more than one, they should be exactly the same or you will spend a lot more time calibrating.

I kept my questions general because I wanted a full range of responses. (But, regardless of the forum involved, I get tired of the responses which begin with: “It depends…” or “I have not tried it, but… ”.) I already have an Infinity Intermezzo 1.2s. I have an opportunity to purchase a used Velodyne DD 18 (2007) for $1,700 or purchase a new Paradigm Sub 1 for about $2,200. This conundrum is a matter of opportunity.

The DD18 probably plays lower than the IM 1.2s. It might even be louder.
Everybody I know with the DD wants to sell it for a DD+.
The Paradigm is great as well. And lastly...
How are we supposed to help in "rare turf"? How many members on this forum have any one of those three subs. And let alone, how many live close enough to attempt a "showdown"...
I like my big M&K.

Here is my equipment:
Pre-Pro: Anthem AVM 50V
Amplifier: Anthem PVA 7
Center: Paradigm CC570 v.3
Fronts: Paradigm Studio 40 v.2
Surrounds: Paradigm Studio ADP-590 v.1
Rears: Paradigm Studio 20 v.4
Subwoofer 1: Infinity Intermezzo 1.2s
Subwoofer 2: Paradigm PS-1000
Subwoofer 3 (new, unopened, not in use): Def. Tech. Supercube 4000
Source Blu-ray player: Oppo BDP 95
Projector: Panasonic PT-AE4000U
Power management: PS Audio Power Plant Premiere AC Regenerator
I have a vaulted living/dining room that is 24’ long and 15’ wide. The screen is at the front (8’ end) of the room and the listening position is about 12’ away, with the remaining 12’ behind the seated area. The vault is 16’ high, at the back of the room, behind the seating area. The floors are hardwood and the walls are sheetrock. We have two sofas, two bookcases, a table, a buffet and some things on the walls. The main use of the HT system is for movies. The sound, especially the dialogue, is not as clear as I would like (i.e., not as clear as the theater I built in the basement of my old house). I have an opportunity to get a subwoofer at a great price: A used, 2007 Velodyne DD 18 (with room correction) for $1,700, or a new Paradigm Sub 1 for about $2,200. In reality, most of the problems with the sound are due to the acoustics of the room, but who can pass up a deal like this for one (or both) of these subwoofers?

More... The front, right half of the room opens on one side with a ½-high wall to a closed hallway, and the back, right half of the room opens to another hallway and also to a second open area to a den. Basically, the back half of the room - with the vault - is open.
The CC is directly in front of the seating position and is tilted up about 30 degrees to aim directly at the listeners’ ear. The CC, fronts and Infinity sub are on a similar line facing the seating area, with nothing in between them and us. There is a large rug on the floor between all the speakers (including the CC) and the seating area.
The suggestion of buying one Sub 1 now and getting a second one later is a good idea. I like having two subs and having them matched will probably improve what I am hearing/feeling.
The last issue, that I didn’t want to muddy the waters with, is that we will probably be moving in 6 to 12 months. Unfortunately, we don’t know where we are going. But at least, we will be taking our HT equipment with us (again

we will probably be moving in 6 to 12 months

Had you stated this earlier or at least posted your location, I would not have suggested internet direct companies that either didn't ship outside of the US or made it extremely expensive to.
But if you are heading this way, then I suggest you wait. Then go with SVS, Hsu or Epik when you get here.

This thread has been moved to another thread: "What are the sonic differences between…" at: http://www.hometheaterforum.com/t/323797/what-subs-do-you-think-will-pair-up-best .

Since I don't see any easy way to combine these two threads that make any sense, I will lock this one and let the conversation continue in the "other" thread.

Note to OP, please keep continuing conversations confined to one thread.
