Well, I had been talking to SVS about an upgrade path and I was looking at one of the cylinders, possibly a Plus because I have a fairly large room and the PB-10 always did well, but wasn't quite moving enough air for this room - 19x20, high vaulted ceiling, open to the kitchen (total is ~5K+ cf). Around the same time, I was talking to a buddy of mine who likes to build his own subs and he mentioned he was almost done with his new project, so I asked what he was doing with the old one..."I'm selling it. Why, you interested?" ....

Check out these numbers in my room (corrected, NO EQ):

Freq. dB
160 - 75.5
142.5 - 74.5
125 - 81.5
111 - 82
100 - 84
89 - 86.5
80 - 89.5
71 - 81.5
63 - 87.5
56 - 80.5
50 - 81.5
45 - 85
40 - 87.5
36 - 86.5
31.5 - 87
28 - 83
25 - 83
22 - 79.5
20 - 79.5
18 - 78
16 - 74.5

Calibrated from listening position. Gain is at just about 30% on the amp which means there's a LOT more available, subsonic filter set to 14Hz (sub is tuned to 17Hz). It's flatter than my PB-10 at the top, though I still have some squiggles in the 125-63 range. Overall, I'm very impressed with this guy. The first time I fired it up, with 50% gain without calibrating, I was literally startled by the output

I popped in Master & Commander because it was the first thing on hand, and all I could muster was a stupid grin and "Holy crap." The rumble from the cannons was simply jaw dropping. I tried out a number of the standards; all being quite impressive. I have not tried out Incredibles or "Darla" yet, but it should suffice to say, this one is a keeper. I do have pics, but I'll have to shrink them down to post them later. I still have the PB-10 too......though it will be up for sale soon (there are a few people in line, if those don't happen it will be up).

Dat sub is woke'n...


Can we get an idea of what you paid for it????


I know it is a little rude, but it sounds like you may have gotten a deal of the century with those numbers.

[John Garcia]

That's a secret You really don't want to know...though I will say it definitely is up for an award for deal of the century Many thanks to Jeff for the deal!!!

Not exactly petite (not it's final home, it went in the corner):

But you can't see it at all with the way my system is set up.

It's a 73L cylinder, 48" tall, 18" in diameter, tuned to 17Hz I believe. Downfiring dual VC 4 Ohm 12" Adire Tempest driver, single top firing port (low Q design).

Whoa ! You sure your house is built to take it?

[Dustin B]

John, not that it really matters, but could you check with your buddy again about what the design is. Are you sure it isn't a Shiva instead of a Tempest. Also allowing 8" of the height to be legs and end caps that works out to an ~160L enclosure. Take away port and driver area and you get an enclosure that is pretty close to the EBS allignement recommended by Adire. Or in other words, something very close to a SVS 16-46CS.

Since the new drivers haven't been released yet, there is no 12" Tempest. If it is a 12" model, it's a Shiva. They are only available in dual 8 ohm models. Dan did sell an overstock 12" model with "VAMP" stamped on the dust cap that was a dual 4 ohm voice coil configuration.

Quote:

single top firing port (low Q design)

The low, mid and high Q alignments are all sealed boxes. Ported alignments suggested by Adire were called the Adire Alignment (85L, Fb=20hz), SBB4 (94L, Fb=22.2hz) and EBS (142.5L, Fb=18.1hz).

With an 18" diameter sonotube that is 48" tall, you are approaching close to 200L of enclosure volume.

There may be a lot of amp left but in an enclosure this large, you are limited by the mechanical excursion of the driver. The Shiva is an excellent driver but only has 16mm of xmax.

That's great. When you are ready to upgrade again (and you will), drop by the DIY section and we can help. We may even be able to re-use your current enclosure.

It's an older sub, I think he built it a few years ago (so it's only new to ME, not new). He definitely built it before the drivers were discontinued. Maybe it is a Shiva though. I didn't check the measurements of the cabinet volume, I just looked at the site figuring what they had listed were still the old drivers, since the new ones haven't been released. Jeff said it was called a low Q design because it used a single, long port and has lower output but also lower extension; it's very clean. I don't remember who gave him the specs to build this guy (possible Adire), but it isn't a "normal" alignment. So 160L? When are the new drivers scheduled to be released?

Will do. I can't see needing more than this for the forseeable future, but you never know Thanks. I've built my own subs before (sealed dual 10") with great results, but nothing like this guy.

Next month. That's been the rumor since summer.

Sounds like a monster for sure. Congrats.

I'm eagerly waiting for my new HSU STF-3 to be delivered today.

[John Garcia]

Oops. I thought it was weird that it was a 18" tube and such a large volume for a 12" driver. It's a 15" Tempest, NOT a 12" driver, which I guess would have made it a Shiva, as was mentioned by Robert_J.

Can I just say that War of the Worlds was pretty scary with this thing?
