I wonder if they're going to include a high quality audiophile grade USB cable so no bits are lost in transferring their files...

*edit: Actually in the comments there's people arguing over whether or not you'd be able to tell the difference between a flac/wav and a 320 mp3 "on a decent pair of speakers". I have an entire rack of kit for my PA which enable me to run the system completely flat from 30hz-20khz. I've played MANY mp3 files on it and compared them to wavs and flacs at high volume. I noticed no discernible difference, certainly gently caress all to care about.

...so what do they mean by 'decent' speakers if a flat system gives up very little in terms of difference?

They have products in every price class, for instance their selection of speaker cables extends from a modest $735 for the basic model, to $30,500 for the 25th anniversary model. Both prices are for a set of two 2.5m cables, finished with spade lugs. Cables for longer runs or bi-wiring cost extra, naturally.


Oh hey I have that speaker cable! It cost £50 for a 100m roll and I made up my own Speakon cables with it for my PA kit. Same gauge. It just appears they've put some braiding over the rubber outer and cleaned off the powdery poo poo from the + and - inners and popped some spades on. That justifies the price alright.

Every time I see poo poo like this I genuinely question whether or not I should do it too. The cash would be loving lovely.

I feel like trolling some audiophiles.

I bought it from an ebay seller called Pro Line Audio and it was a bargain, they're currently not selling anything but Thomann has basically the same thing on offer for a few quid more (but still farrrrrrrrrrrrr cheaper than what they're asking)

100m of 6mm for 280 Euros/2089DKK. 6mm sits between 10/11AWG which is thicker than the poo poo they're charging 163,500DKK for... Bargain! Get some braid, a bit of shrink tubing and some spades and nobody will ever know the difference.

Today I was thanked by no less than six people after being forced to speak up at a seminar to point out that a well respected audio industry figure fundamentally misunderstood digital audio. He was trying to A-B test a cheap USB cable against a ridiculously expensive one to show how much warmer and more detailed the expensive one was.

Whilst telling people which was which.

On a PA system, which was purple. The cable was purple too.

By unplugging one and plugging the other in whilst a tune was playing continuously. Of course he was using Fidelia. And a £4000 soundcard. And mentioned skin effect as a potential cause.

On the whole it was good but you could blatantly tell that he drank the audiophile kool aid.

Is it a weird thing that I quite like having actual copies of music I like as opposed to just streaming it all? I just have this mild loathing of streaming ever since someone tried to entertain a houseparty by using a non-premium version of Spotify complete with adverts. It just boils my piss for some reason. If you like the music why wouldn't you have a copy, even if it was just a 320? Seems stupid to me, like a slacker's version of entertaining people.

When people come over to my place for a party I have hand selected playlists ready to go because it's great fun. Spotify just seems like a non participating way to listen to music, passive listening.

I was under the impression that twisted pair cabling was used to get rid of the kinda poo poo that audiophiles are always banging on about that wrecks their soundstages and such...

My Driverack PX comes with a calibrated microphone and can do room correction (as well as crossover, subharmonic synth, parametric/graphic EQ, compression, limiting and feedback elimination). It costs $600 MSRP, but can usually be found for around $375 new. I bought mine for $220 used. It does everything that stupid player does, better and for less money.

Oh yeah, and it has only analog inputs/outputs, but everything internal is done digitally. The workflow goes PC->DAC->preamp->ADC->processing->DAC->class D amp, in order to really piss off the audiophiles.

I have the Behringer version of that in my PA rack. It honestly amazes me how many sound systems local to me just have EQ and not RTA... First thing I do when I set up the system is run the RTA to get everything flat and then tweak from there. It's weird hearing an accurate PA system in a room, it sounds just like a massively powerful hi-fi. :awesomelon:

Sub-20hz tones can affect the middle ear if played loud enough, and that can cause nausea for some people.

True but that thing is so loving tiny there's no way it's capable of outputting frequencies that low. It's a little box with an LED on it, pure audiophile grade toss that doesn't do anything. None of the poo poo on that market does.

I know a fella who runs iNukes on his PA system for days on end from a generator (which class D amps loving HATE) for illegal raves in abandoned warehouses and such and he raves about them. They're nowhere near the ratings suggested (they used to include the actual ratings in the manuals online but removed them) but given a sensitive system they'll run hard for a long time and sound decent too.

...but then again they're Behringer so they can't possibly be any good.

I reallllllllllllllllllllly need to move house and get a place with a decent sized garage so I can get back to making speakers and selling them to chumps with too much money people with discerning tastes.

I've recommended active monitors to quite a few people for small room audio requirements, not many people take my advice but those that do are more than happy at how nice they sound. poo poo, even the low end of the monitor market are pretty decent for the cash (though they tend to be pretty ugly).

If you're a bit handy with wood, and especially with veneers, you can make some really beautiful boxes. For home use, it's probably 90% aesthetics and 10% sound that sells. And of those 10%, it's mostly about the thump-thump. Expensive-looking box + cheap drivers = profit like woah.

I REALLY loving hate veneer though, it looks so loving cheap and nasty. I like wood. Real wood. Not MDF with a thin sliver of wood over the top. gently caress that poo poo. :/

This year I'm going to play around with a few designs in acrylic I think, a friend has seen some speakers he likes in clear acrylic but the actual design itself is a bit lacking so I want to have a play and improve that a bit. That shouldn't take too long and then onto some wooooooooooood.

Doesn't MDF have sonic advantages because the density is uniform? At least it should be easier to design with.

MDF is used because it's cheap as gently caress. It's sawdust and glue. It's barely related to wood as it is. I like using plywood, the top quality birch stuff, it's actually really pretty and I want to make some big folded horn PA subs out of it and put a nice stain on it because as it's wood, it has a grain and takes it really well. I built some PA speakers previously out of it but painted them and I now realise it was a mistake as they would've looked sharp with a stain. That said at that point my woodworking skills probably weren't quite up to scratch to pull it off.

I like wood because it's a real material, MDF is just really crappy to build with. It crumbles when struck, absorbs water like a sponge, is heavy in comparison to equivalent sized plywood, isn't as strong as you think it is and is loving carcinogenic so is actually dangerous to use unless you've got a mask and decent filtration while you're cutting it. Anyone selling you on the idea that MDF is a great material is trying to hide the fact they're trying to cheap out on you.

I know what MDF is, but isn't the fact that it's denser than plywood (and uniform in its density) an advantage when you're designing a speaker?

Plywood is also uniform in density. I suppose you can call a higher density over plywood an advantage if you want to skimp on actually designing a speaker properly. It'll be an advantage if you don't want to think about adding internal bracing to say your sub design. But I'll take internal bracing, lighter weight, strength and all that other stuff over using MDF every single time. In terms of something like sub building, if your design is good then it'll spend its time rattling the room it's in rather than rattling itself all over the room. The designs I've built previously are all 12mm birch ply internally braced, the subs capable of silly loud volumes (120db+ outside measured from 5m) and yet didn't move an inch hitting said loudness.

So basically you have to do more work to make plywood work as well as MDF, which is OK if that's what you want, but don't act like you're not making a tradeoff when you choose either.

Spending 30 minutes cutting a few braces on a particular design isn't really a trade off in my opinion. You can no doubt make a speaker with no bracing out of ply if you wanted to, the designs I've used are braced for lightness but you could definitely go to 18mm ply if you wanted touring grade toughness. If you were to make them out of MDF the only advantage would be they'd be cheaper. In every other respect it's a worse material. I get that some people are cool with it and that's fine but I've used a better material, it's far nicer to work with and that's what I'll be using from now on. My floorstanders are manufactured from MDF and a veneer and it's fine for those but for something I'm making myself I wouldn't use it for all the aforementioned reasons.

I've never built a speaker box, but I feel qualified to comment on this because I spent a decade doing finish carpentry for a living and I still do it as a hobby.

For painted work MDF has taken over the carpentry industry because its easier to machine, easier to finish, cheaper, better looking, more stable, etc. As with every material choice you're making tradeoffs, but to act as if MDF is the obviously inferior choice is just wrong, wrong, wrong.

It's inferior for my spec for the reasons listed above, I'm not suggesting you can't use it to put together some speakers as it's evidently possible but for what I need a material to do it's not fit for purpose.

ABX is dumb and won't work, because music is art and science can't quantify art. It can also be thrown off by having parts of the system set up wrong, where the distortion can overwhelm the part you are trying to hear, eg cables being plugged in the wrong way or CDs being played live without an anti-jitter treatment.

I'd also be very interested to know the set-up they chose; were each set equally burned in with (at least) 200 hours of white noise?

Wow do you even know anything about audio? Cables must be burned in using PINK NOISE. Using white noise just gets you cables that are burned in on the high end but muddy and indistinct on the lows.
