Except you gotta give him more than that nugget to make it less of a joke and more understandable.

It's about length and resistance rating (ohms)

The distance from your AVR/amp to a set of passive subs across the room might require a heavier gauge wire, but smaller gauge wire can transmit a LOT of wattage for short distances. For the purposes of the speakerpower amp which is IMMEDIATELY next to the drivers - you could use pretty small gauge and have no adverse effects.

Take a look at this chart.

Yep. This is good too since you can put in your own numbers.

I bought 14 guage for my back wall subs since I would lose less than .5 of a decibel. I'm so sick of dealing with 10 guage wire and why mess with it if I don't need it.

Man I wanted a pair of S2's so bad and almost had em. The deal I got for my Triax's was a no brainer. Those drivers in the S2 look similar to the original drivers that were supposed to go in the Triax. Never did catch the name of manufacture of them, I am wondering if they are the same. The newer revised Fi drivers added 40 lbs to the Triax's final design.

I've been listening to music for a few hours now. And I really hate the 212s...I'm going to have to dig out all of my CDs from the past 25 years and find HQ mp3s/flacs. They are exposing any badly ripped track, stream, or recording. This is madness.

LOL, and man oh man, there are some horrible recordings! I don't find much older music sounds good, some is ok of course but blah. Pretty much any new aged dub or anything like that sounds awesome though!

Realistically it's not an apples to apples comparison. The PB Ultra is a very nice subwoofer that does exceptionally well considering the Driver is only 13.5 inches. The Cap2400 with its 69lb 18" driver is just that much more capable. The Ultra has a Sledge/ Bash amp while the Cap has a Speakepower 2400wpc amp.
With the differences in the amp and driver the Ultra does not have a chance from the performance aspect. Jeff (JTR) can also sell his products with less profit margin so dollar to dollar the Cap comes out on top again.
There are some on this thread who have owned both so they may add something to the comparison.
Good Luck

Archaea could answer this really well I bet, but countryWV is correct. I other words, the Captivator 2400 should smash the Ultra.

I use to own two of the PB13 Ultras with the previous generation Def Tech speakers. They are really nice subs but the Caps are just that much better. I had Jeff Meier over a couple of weeks ago and he said Jeff is the King of Subs. He said he's never had an issue integrating a JTR in to a system. Said he recommends them all the time. I haven't had a ton of time with my S2 but I can tell you without hesitation, get the JTR.

We have not hit rock bottom yet. It will get worse before it gets better. The ones who can do something about it are caught up in Pettiness while the ones who can't (middle class) pay the price.

It is as simple to see as 2+2=4 yet it still goes completely ignored overshadowed by social issues. Rome is burning while we are mesmerized by the flames.

As you know, QE is the money faucet...turn it off and the market goes KABOOOM!!!!...it might go KABOOOM all on its own as people realize the market gains over the last 5 years are largely artificial smile.gif

Yes, but the sheeple will believe the government and talking heads that it is free markets and businesses that are the cause, and more government control/intervention will ensue. For the good of the sheeple, of course. smile.gif

Having said that, political discourse is generally frowned upon around here since there is always someone with an entirely opposing viewpoint that will get feathers ruffled. biggrin.gif

So I'm going to get back to talking speakers. wink.gif

I saw the Lego Movie last night at the theater. Good sound for a regular non-Imax theater. Now I have to have a talk with my kids about the main villian of the story, the evil Lord Business...rolleyes.gif

Right, this is what I'm pointing out.

The reason I mention it, my non-dedicated HT is open to a kitchen space behind the LP, and I can hear a difference when LCR energy reflects off shipping boxes stacked on the normally empty countertop behind my seating.

I like the diffuse, multi-angular surfaces that make up the kitchen, but have learned the significance of returns off some surfaces can be detrimental spatially.

Get the 2400. And if possible now, or later, get two to balance out the bass...once you hear/experience how two subs improve the movie watching experience, you'll never be able to live with just one. You will save good money if you buy both at the same time, with any discounts & shipping once.

I reran Audyssey and measured 6 location points, per manual which I finally read last night. I'm guilty of trying to measure only one location, which is the MLP and thinking Audyssey should be able to figure it out and it won't make a difference...but it sounds so much better now to me. Huge improvement. So if you're just measuring like I did for one MLP, give it a try and see how it works for you...it does take longer, but worth it imo. Here's the measuring pattern I used since sr7008 manual didn't give a sequence order and just points for one MLP:
4 5 6
3 1 2
(1 being MLP and I kept about 3 ft displacement between points)

Even though I set the shifters +1 on sub, Audyssey set it to -12dB and I just raised the levels on avr to my liking, which is +1dB.

A minimum of 13 dB over reference? If I hadn't spent a lot of time on this thread I would tell you to run Audyssey again since you must have a bad cal run. But I know the bass heads love crazy hot bass, so I'll just say I'm glad you have it where you like it. That is all that matters. biggrin.gif

Edit: I'm curious, have you measured your room post cal?

I know what you mean. I think after I put in some treatments and bass traps, I may not even have to run it that hot. Also, right now I have both shifters corner loaded, so still playing with placement and seeing what sounds/feels good. The entire house quakes nonetheless...bass out of the shifters is so clean, tight, and powerful, its scary.

PopaArchaeasSocket Austin is planning to come by today, so we're going to try to get some measurements.

Great plan. A lot of things could be happening with your FR that makes you feel like you need to raise it so high. Corner loading both subs may increase output, but may not give best FR. For instance, in my room I can only get away with corner loading one sub for best response across all seats. But every room is different, so there's no alternative to measurements.

Haha...don't worry, I've pulled it back some. I was pushing it for a couple of scenes, but have it at +6dB over ref right now. But I saw WOW scene at prior setting of +12 over Audyssey's reference, and man, I thought house was collapsing.

Also, just a few rules I accumulated along the way after many fruitless multiple sub optimization attempts.

A common mistake is to move the subs around trying to get a ruler flat pre-EQ response across your seating. In my experience it will only lead to frustration and at least one "bad" seat when you're done. Instead, the goal should be to optimize the FR for the EQ that will follow. Which means a goal of the same non - flat FR across all seats. The primary objective being eliminating nulls, even if that produces significant peaks. If the peaks are the same across all seats, EQ will smash them flat.

Bottom line is optimize for the EQ which works best on problems that are the same everywhere, and eliminate nulls that EQ can do nothing about.

It took me a fairly long time to figure that out, although when I write it, it seems so obvious. smile.gif

Earlier, a couple guys mentioned Trinnov and Dirac. Anyone contemplating the new Emotiva pre/pro with Dirac?

http://shop.emotiva.com/products/xmc1

I realize that Trinnov > Audyssey, but how does Dirac compare?
