REL Acoustics No.31 Overview

- Hi there, John Hunter with REL here, and we are here to take you through the No.31. Now, where this resides within the REL hierarchy is, this is one down from our No.32. The 31 was actually started before the 32, hence the numerology. But what the 31 has the task of doing, and it's a great one for everybody who falls in love with the No.32 and goes, “I've got to have that,” or “I've got to have a line array of those,” and then looks around at their room and goes, “can't happen, amazingly, I just don't have the room to do it.” 31 is considerably more compact. It's 35-40% smaller in volume. You can see this doesn't even look large on camera. It's incredible. A line array of these comes up to here. It's nothing. So, it flows into almost every room out there.
It is exactly the same quality of construction as the No.32. It's just a bit of a size reduction exercise, but the quality is identical. All right, so the 12 inch driver in this is contrasting with a 15 inch that we use in the No.32, a full carbon fibre cone. Now, we don't go for the single, very pretty, hemispherical piece that's just laid up in a hemispherical mold. They're fine. They don't do what we need them to do. There's a speed and a tactility to REL drivers. And one of the techniques we use to achieve that is we use different carbon fibers for the actual, center cap as opposed to the main body of the cone. And by using two different pieces laid up as a composite, we wind up getting something that's much, much stiffer, doesn't weigh anymore, and you get a much better controlled performance out of the piece.
What we're going for is instantaneous start, stop in the reference. It's extremely important that we not overshoot and lag, and that when it stops, it doesn't continue to make a little bit of residual input. It's got to start and stop with the music. It's got to start and stop with a special effect in a movie. And that's what we go for here. This is a driver that is really, really over designed for the application, but it's because we intend for these to still be running 20-25 years from now.
The amplifier that's used in the 31 is a precise duplicate of the one that's used in the 32. The only difference, and the reason there's a wattage rating is because we deliberately use our limitless limiters a little bit more aggressively here to limit because the driver's a 12 inch instead of a 15. It is all the same components, identically reusing the power supply board and the amplifier boards themselves.
We have two parametric filters on this exactly like the others. It's exactly the same formula second filters that we use in the No.32. It is a duplicate. The only difference is it puts about a hundred watts continuous out less, as I said, that's just to accommodate those. Briefly, the parametric are designed to allow you to gently lift the extreme bottom end up. I'm talking about typically below 25 hertz, just a little elevation because most rooms begin to fall off, the room does, not the subwoofer. So, we need to accommodate that. And then the second filter, the B filter we use traditionally to just pull out, above your crossover point, very subtly. And what it does is it produces a cleaner, more transparent mid-range and high frequency signature. So, let me take you on a very quick, short guided tour of the cabinetry of these bases.
It's simply incredible. First of all, we'll just start at the grill. It's absolutely beautiful. I claim no authorship of this at all. This was inspired by Franco Serblin of Sonus Faber fame. He wanted it on his designs to mimic the approximate strings spacing and things of a violin. Here we are, working with more of a cello or a double base spreading, but it's done in our case principally is a functional issue, these drivers put out huge amounts of very large weight fronts. You know, when you've got a driver that can explode two inches out, it can put out huge amounts of air pressure in a conventional cloth fabric grill, would just stifle that. Frankly, it would probably blow off the front because you're moving so much air that it would eventually just pop it out of the fixtures. - Навчання та стиль
I am going to visualize owning a pair of No 31 in my home theatre room 😊
Six!!!!
Get the 1510, I have a pair in mine and love the output.
@@czwhat328 just got my 1510, having a hard time getting it to hit right with my Klipsch 5.1.2 setup. Still working on it though, I loved my 1205.
I also have an Airship 2 coming in the mail. I'm going to try and take advantage of high level the best I can
@@cainification what avr are you using? Make sure to turn the gain knob to the half way mark
I wish the S line looked more like this No.31. Or with rounded corners at least.
Just ordered a pair!
Thank you for your order, and we hope that you love the performance of the pair of No.31s in your system!
What sub would you recommend To go with my Linn Klimax 350 organic system
Thank you for reaching out. When you have a chance, please write in to contactus@rel.net with the model of main loudspeakers that you are using, the model of amplifier that you are using to power these speakers, and the dimensions (length, width, height) of your room. Once this has been provided our team will be happy to provide a subwoofer pairing recommendation specific to your system.
I want one for Wilson Audio TuneTot speakers. Is it a good match
Thank you for reaching out. The No.31 subwoofer can perform well with the Wilson Tune Tots, though it is possible that one of our other models will be a better match for your system. When you have a chance, feel free to write in to contactus@rel.net with information about your room and equipment and we will be happy to provide a subwoofer pairing recommendation specific to your system.
I have avantgarde acoustic Horn speakers, is rek no 31 fine with that? Speakers: uno fino edition
Thank you for reaching out, and for your interest in REL Acoustics subwoofers. When you have a chance, please write in to contactus@rel.net and our team will be happy to provide a subwoofer pairing recommendation specific to your system.
How much better is it from the carbon edition?
Thank you for reaching out. While the Carbon Special is an exceptional subwoofer, the No.31 offers a substantial improvement in performance comparatively. For more information about the differences between these two models, feel free to write in to contactus@rel.net and we will be happy to assist.
So 1hz per click but on everything else it's logarithmic so hard to work out what the crossover is set too 🧐🙄
when you think of it, then the Hertz scale is in itself logaritmic. You gradually increase the frequency, but you will gradually increase it less and less per click. So even that is logaritmic. A linear Hz scale would not be like one Hertz per click. Because when you go from 10 to 20Hz, you go up one octave. And you go up one octave from 20 to 40. and 40 to 80 and so on.
