I saw a review of some very nice Krix speakers the other day, the review was quite well written and low on bs but then I saw pics of his set up, he had speaker cables with silly little stands to keep them off the floor!  :palm:

I just can't take anyone seriously who thinks these have any use whatsoever!

They let you sweep/clean underneath the cables.  That's a use. :)
It increases the cable rating as its in free air and can thus deliver a purer sound to the speakers and a higher wattage as well, thats a real bonus is that  :-DD

I am missing something? They don't say what it receives. There's certainly no Free HD TV floating around the airwaves anywhere near me. Is it just a fancy DVB-T antenna?

Bryce.

Yes, it's for DVB-T.
Just conventional terrestrial TV Stations.
The Digital TV broadcasters we have in Australia, are commonly called "Free to Air"(FTA).
Of course, they aren't all HD, but many of them are.

Free?---- we don't have TV Receiver licences, so the National Stations ( ABC) are paid for by the taxpayer, & the Commercial Stations by advertising revenue, so indirectly, we do pay for both.

As we pay whether we use,them or not, they are, effectively, free.
You can certainly get better antennas than the one shown, probably cheaper

Here in Germany you pay a TV license, but that only gets you standard resolution TV and there's not many of those left anyway. Anything HD costs extra. So DVB-T is pretty much empty unless you pay for a HD subscription (about €70 per year).

It might be true for some types of floor.

The wrong sort of floor could turn the cables into inductors and that would wreck the sound.

Have you seen the Cables AudioPhools use? Those things use more shielding than what you'd find in state of the art RF / EMP hardened Military gear!

FWIW, here's the review: https://www.stereo.net.au/reviews/review-krix-esoterix-altum-bookshelf-speakers

and the cables in question!  :palm:

Fools, don't they know that hard, shiny surfaces like that floor for instance actually colour the sound and so they are not actually listening to the pure sound but slightly distorted sound. Secondly, the quoted frequency response of those speakers is 40Hz to 40Khz, why? I say why because it is a fact the the human ear can only hear frequencies in the 20Hz to 20Khz. That means that only animals can appreciate the upper infrequence between 20KHz and 40Khz. So not only are they missing out on 20Hz of pure joy, deep bass but the speakers are also supposed to to be able to produce sounds 20Khz above the human capability of hearing, why???

Thats proof enough to demonstrate that there are people around who are clearly deluded  and are easily parted from their money. And that cable and the fancy stands for the cable is another clear example.

Lol, I personally have carpet in my HT room simply because I dislike the reflections created by hard floors. My system (w/400w, 300mm active sub) goes down to 16Hz which you can definitely feel more than hear (which is kinda the point with movies).

but yeah the 40Khz top end response is pointless considering the only way to perceive frequencies above 20khz, is via bone conduction ... which would require you to strap the speaker to your head! :palm:

I thought bone conduction was only good into the 3khz or so. I played with transducers and found that so.

If you can tell me how you can get 10's of khz through bone conduction, tell me.  Maybey your cochlea still has to work there?

You could well be correct, I'm no expert on the subject but I did read it somewhere on the internetz once, so of course it must be true.  :-DD

9 out of 10 fruit bats said they preferred these speakers. :)

@Fungus: The cable would have inductance no matter what floor it was lying on, just some floors might increase the value.

That's just the point, in the demo room they have wall to wall carpet and the other speakers on test are huge. In that case it is easy get the audience to select which ever set of speakers you want them to by selecting the audiences by their preferences. Take my wife as an example, she hates deep bass and large speakers preferring small unobtrusive ones, find similar people to make your test audience and you get the smallest speaker picked as the winner. Simple as that, big speakers get written off from the get go purely on sheer size and then because they will also produce the heaviest and deepest bass, bingo ladies and gentlemen your winner was predetermined.

There is also a world of difference between bass and boom.  Boom, is when the speaker just makes a nondescript noise whenever a note below 100Hz or so is played. In the worst cases it's not even possible to tell what instrument played the note.  :-//

The audiophools dote on boom though. Especially the car audiophools.

Real quality bass is well defined and not just a one note samba that you tend to get the car audio lot whose main aim in life seems to be moving as much air as they can with their sub woofers. Anyone who has been in a large church/hall/theatre where a pipe organ is playing will of course know that part of the deep bass is also the ability to feel the bass in your body and the lower the note, the greater the feel and less actually hearing the note.

Now to my mind, the job of hi-fi and speakers is to try and reproduce the sound and the feeling that you get by being there and if the equipment is not capable of such reproduction then it is not true hi-fi and in the case of these speakers referred above, how can they be classified high end hi-fi speakers when they are incapable of giving you that lovely spine tingling deep bass that you can actually feel?

I've had the sheer pleasure of being in a theatre when a Wurlitzer pipe organ was being played and some of the bass notes are really deep and prolonged and down in the infrasonic range and speakers that cut off at 40Hz just don't cut the mustard.

Those speakers are total trash. They look like cheap podiums from the 1970s, and they have little horns (an absolute no-no for modern speakers) meaning the drivers are weaker than bluetooth speakers making the sound "hollow". (this would explain the terrible frequency response) I bet those damn things sound like crank phonographs. :-DD

I want one of those (if it actually works). ;D More of a "because it can be done" novelty than anything practical. At least it's cheap, unlike most audiophool crap. Although it would probably be more fun to DIY.

We should send one to Paul Carlson and see if he can figure out what it is. >:D

... and not just the air, but the boot lid, windows and door panels.

While a few car owners have addressed this, there are so many that drive by and all I can hear is some muffled music (at least I think it's music) from within the vehicle accompanied by the dominant metallic buzz of the boot lid as it alternates between the boot imploding and exploding.

Considering the money put into such systems, I just laugh to myself.

I myself have an upmarket sound system fitted to my car, not an after market option but manufacturers option on the particular model I have and sometimes the bass on it can cause various parts of the car to vibrate and rattle on really deep and high energy bass and thats to be expected. However to go to the extents that some people go to with the whole car being in effect a mass of speakers and huge great power amps in the boot which effectively turns the car into a music system on wheels and thats all its all its good for as there is often no passenger space either, is simply ridiculous.

These nerds will be stone deaf before long...

That's a really cheap unit and I bet it would struggle to deliver the quoted power output and has sky high distortion figures and has poor frequency response to boot.  :popcorn:

It's got a class D amplifier which makes that a perfectly credible specification. I cracked it open - has a Chinese IC in it. Possible to get THD down to 0.03% easily with those. Haven't measured it but it sounds pretty excellent even with shitty Fiat default speakers. And I'm throwing Ralph Vaughan Williams' Lark Ascending performed by the Royal Philharmonic Orchestra through it which has an excessively large dynamic range and no compression.  :-+

The thing is regardless of the promises, it delivers 99% of the performance of something 1000% of the cost which makes it a good value proposition. Good job China  :-+
