WOW so many good choices but hands down 2 Sub2's from paradigm or and I say or because i never heard of Power Sound Audio Triax. These look like they would be awesome, the specs are great Comparison_Mini_Chart_TriaxJPEG.jpg 27k .jpg file

Does anyone have these or heard them before? I am looking to add a second sub, so far I cannot fnd another sub25. The sub2 is out of reach i would say, but the triax is intriging

Since the room is always a part of the system, it would have to be incorporated into and as a part of any dream system. In other words, the dream system starts with a dream room, than you can move onto gear. For bass, you want to contain the air pressure and not let any leak out. A thick concrete wall would be good here. You would also want the room shaped in such a way to minimize nulls and cancellations at the listening position. I'm guessing that the idea room would have no flat surfaces, just curved surfaces to diffuse the waves and prevent cancellation. You would need plenty of power, so lots of high amp circuits available. It should be heavily treated, so all the frequencies sound nice, not just bass. You wouldn't want a large room, maybe something sized in such a way to optimize pressure vessel gain.

Indeed. With the rotary sub I mentioned that would mean significant alterations and a proper space for installation. Might need a proper built house, not just room!

Thanks for describing my room, even though you have not been in it!!! cool.gif Apart from curved surfaces that is.

Thanks for the suggestion.  I have the miniDSP, just struggling a bit with an output issue.  The upgraded AVR equipment rack route is an option down the road, but will likely be next year as I have basically been building my entire system from scratch since late last year.  I still need to upgrade my second sub later this year.  I think I win the award for most mismatched subwoofer combo ever.  For me, WAF goes beyond asthetics.  I have to put some time behind my recent purchases, but I do see my next steps as surround speakers(soon), XS15 as my upgrade to the Polk(later this year), 70"(black friday?), new AVR and rack(next year).  I want dual sub output and eq ability when I change AVR's, and a second zone that can play a different source if that is possible.  Like some music outside and tv inside.

This is with 4 of the IB subs playing, as I can only measure one channel at a time with REW and HDMI. Now double the RE XXX drivers get get an estimated SPL in room, add another 4 x LMS ultra 18's that I have started building for the corners of the room. And as long as I am getting over reference SPL levels @2hz I will never, ever leave me wanting more.



Pics of the 4 subs behind the screen.



Yeah, I know, I have to get my act together and get a few updated pics.

I have 3 and they are amazing. Flat down to under 5hz in my room, even with 2 they were flat to 5hz. I would think they have more and deeper output than the Sub2 (as would the JTR S2)

Here is info from paradigms site about the Sub2

"Our Vibration-Canceling Design Architecture is only part of the story. There's still no replacement for displacement: In a small, compact form factor, six 10" drivers in SUB 2 move more air than a pair of 15" woofers! SUB 1's six 8" drivers move as much air as two 12" woofers. The other part of the story lies in the cutting-edge design of the bass drivers"

The triax has 3 15's

There is a dedicated triax thread here:

http://www.avsforum.com/t/1492820/official-psa-triax-thread

3 - JTR 228's LCR (game room)
4 - DIY Sound Group V-8 Coaxials in slanted boxes (game room)

That is an awe-inspiring system JapanDave. A couple questions, how do measure 2 Hz? Also do you know how clean the output is down to the single digit frequencies, ie what kind of THD are you getting down there, at say Reference? At what SPL point does THD climb over 10% would you say?

Not really, two Magico 18"s would still cost more than your system and only provide a small fraction of the performance.

JapanDave,

at 2 Hz, the wavelength is around 500 feet. Much longer than a room dimension. Unless your room is huge, I would guess that everything below 10 Hz or so would sound and feel exactly the same. Basically the same as getting hit with a shock wave. I'm not sure if there's any benefit at all to being able to play 2Hz at reference as opposed to 10 Hz.

Um they are charging $4k for a sub that uses a mid range 12" driver which retails costs $175. That ratio of parts to assembled unit cost is almost as bad as the Magico. $30k sub/$900 driver vs $4k sub/$175 driver, do the math.

I can only imagine what Bill Fitzmaurice would say about this.... Zu Audio recommends if you run these subs in pairs to place them symmectrically in the front of the room as close to your L&R mains as possible.... Man this is some of the worst placement advice I'd ever heard.

Well, apparently you did the math for me! The Eminence driver isn't pricey, but it does the job! So why the $4K price tag? Perhaps its the internal components, research, made in USA and such? You have judged a book (Sub) by its cover (Driver)!

It's not the worst placement advice. Placing them by the left and right mains will at least eliminate localization. It probably wouldn't be an optimal place for the FR though. In any case, it depends on the room.

Lol, the driver isn't the cover, it IS the internal components. All the rest of the internal components is just going to be stuffing and bracing, and by the way not made in the USA as the amp is Dutch. The 'cover' here is the varnished cabinet. I could almost understand the $4k price tag with those cheap components if it were some kind of complicated transmission line build, but its just a down-firing subwoofer.

In this case it's a pretty significant performance limitation; we are after all talking about a $4000 sealed subwoofer utilizing a single 12" woofer with moderate excursion capabilities motivated by a 400W Hypex amplifier. It's not going to compete well against some of the subs already mentioned on this thread such as the SubM (dual 15" drivers driven by a 2400W amp) and FW18.0 (18" driver driven by a 2400W amp), which notably are North American built (including the drivers & amps), and undercut the Zu on price.

Here we go again. C'mon, guys. Can't there be one thread that can remain on topic without devolving into insults (thankfully that post was removed) or railing on the cost of a particular piece of equipment? It is, after all, a thread that states: "Just a fun thread to see what everyone would choose if money were not an object.  Choose something that would be realistic as far as size goes for your space that you would actually want to have, and what you have now." That means, even the Magico and Zu Audio are legitimate choices.

Music area: Magnepan 3.6, McIntosh MC2205 & C48, SVS SB13-Ultra, Oppo BDP 95 and assorted equipment.
Movie area: EMP Tek R5Bi, PSA XS30, Denon X2000, Oppo BDP 83.

I think confusion is he said flat to 5hz, which I believe that is with a standard FR sweep around 80-90db. I do not think he is saying reference capable down to 5hz.

This is correct.

Here is a sweep I did before I got the 3rd. I can try to do a sweep at a higher lever this weekend. Would i need to do a 105 db sweep or 115db sweep to see reference? I had my avr at around -12 I believe when I did these sweeps.

I certainly didn't expect to get the jabs about the ZU Subs! In my effort to bring the topic back in line, I would also pick the Wilson Audio Thor's Hammer! Its a beast at 411lbs and starting at $21,000!

If money were no object I would put in whatever subs the engineers installing my own personal IMAX theater recommended.

Are we now just looking up expensive subs? You cares what they cost, some of us have what we have because of experiences with certain goals. I have the pleasure of having a small room so reference is easier than a smooth response. I don't need the big guns to get me there or nearly as many as others bu I still have plenty for my room. Showing compression sweeps will tell you how loud one can go at which frequency. Once it starts to compress that is the limit or the response starts to dramatically change. All the hard work for a smooth response goes out the door! Always strive to get headroom at your weakest link then you will be fine.

JapanDave,
What are you using to get a rise like that at 5 hz? Usually it happens two octaves above. Are you using a Bassis?
