Fallen Kell writes "From the anouncement, "Polk Audio LCi-IP Ultra High Performance In-Wall/ In-Ceiling Loudspeakers are the world's first active Internet Protocol-ready Loudspeakers. They were created for IP networked systems such as the ground-breaking NetStreams DigiLinx system but also provide vast convenience and performance benefits when used in analog systems. Integrated digital amplifiers eliminate remote amplifiers connected via hundreds of feet of lossy, performance-robbing speaker wires." I had the great pleasure of having a demo on September 16th, 2005 of these speakers. The ability of connect to a wired network for sending the audio stream is simply amazing and wonderful innovation in the audio world."

    I couldn't load TFA from my PDA, so take with that knowledge:

    Remote digital speakers are a great solution for lowfi and mid i systems, but true audiophiles will not accept them.

    Integrated amplifiers greatly reduce customizing, additional ADCs and DACs reduce resolution, increase the noise floor and change the sound.

    Also, IP isn't my favored priority stream transport. I'd recommend a separate network for sound and I'd be weary of any delays incorporated in the IP transport. Think ping times! Also, encoding with the ADC does not include encapsulation into an IP packet, which can lead to worse lip-sync problems. Even 20ms delay makes me crazy (~1 frame). Of course, if its digital all-the-way, things can look brighter.

    But a start is a start. Here's to hoping it continues to improve. Polk has a decent hifi range and a great R&D team. If anyone can find a better solution, its them.

      Most of these "true audiophiles" are the kind who swear by valve amps, separate elements stereo systems and expensive gold cables. The truth is, there's no reason why well-designed TCP/IP-based speakers would be less good than analog ones, especially over 2m from the amplifier.
      • I don't buy into the ridiculous claims some people make regarding cables, but tube (valve) amps *do* sound noticeably different from solid-state in that their distortion characteristics are different, as any electric guitar player can tell you. A tube amp usually won't have better total harmonic or intermodulation distortion numbers than a solid-state amp, but the distortion sounds better and is often perceived as "warmth".
        • If you can't give numbers to the difference, then the difference doesn't exist. This "warmth" doesn't exist. Its the same thing as the gold cabling.

            It is a quantifiable phenonenom. When solid state devices are overdriven , the tops and bottoms of the waveforms are sharply clipped off. The result resembles square waves. When tube devices are overdriven, the tops and bottoms of the waveforms take on a rounded "squashed" appearance. Both of these effects can easily be seen on o-scopes and heard by not particularly discerning ears. The distortion produced by overdriven tube equipments sounds more pleasant and accounts for the "warmth".

            If we are talking about correctly designed playback equipment being operated properly, there is no audio quality reason to prefer one over the other. Clipping only occurs when an amplifier cannot amplify a signal further. This is not the regime you want your home stereo equipment to be operating in. Tube playback equipment that is not particularly linear (the amplification curve of indifferently designed tube equipment is gently "S" shaped) can sound "warm" even when not overdriven. I'd rather leave how the audio should sound to the artist and trust my equipment to accurately reproduce the artist's intention. Other than basic adjustments like volume or compensating for speakers that don't have a very good low or high end, I don't want my stereo coloring the sound for me.

            If we are talking about playing music rather than mere playback, then tube amps have considerably more merit to them. A guitar player may intentionally choose to overdrive his amp or preamp as a way of altering timbre. Tube guitar amps are even set up to allow control over when and how this overdrive occurs. Typically, this will done in a preamp rather than the final amps as any device in the overdrive state is running very hot and using more power. For that matter, even solid state guitar amps can be intentionally overdriven although the idea is to intentionally introduce harshness rather than warmth.

          The Audiophile appreciates how music sounds on a high-watt system that's driven purely in the linear response region, has inperceptable distortion, crosstalk and noise, has a frequency reponse from 15Hz-22kHz that need not be flat, but must be pleasing to his ear.

          The Audiophile understands that a great system starts with the speakers and works back to the source.

          The Audiophile understands that spending time moving his speakers and furniture around the room will give you the best bang-for-buck improvement in sound.

          The Audiophile understands that the difference between a CD player worth $200 and one worth $2000 is not as important as the difference between a set of speakers worth $200 and that worth $2000 - doubly so if you are keeping it digital until the tuner.

          The Audiophile knows that the person who spend $1000 on each speaker cable is a wanker, while he calculates the per meter-resistance of his quality OFC cables and ensures that the paths to the drivers are as close as possible.

      I built a networked DAC a few years ago at university. Not too hard- the complex bit is making the timing and sync accurate, with the limitations of tiny chip controllers and rather unaccurate ethernet chip documentation!

      Due to TCP/IP delays e.g. switching, you need some sort of buffering, which ends up meaning expensive memory on small chips. Once you have buffering e.g. 0.2 seconds, you should be fine. I ended up using a couple of little Burr-Brown PCM54 DACs, but the system was designed to feed digital into a decent professional DAC.

      That may be the perception, but in many cases (but not all), it's wrong. Integrated amps allow the manufacturer to to cutomize the amp for the specific driver which can greatly improve the performance of the overall speaker. for example:

      • the amp in the Sunfire sub [sunfire.com] (which is rated for 2kW, but doesn't actually deliver that kind of power to the speaker because of the back EMF [hometheaterhifi.com] properties of the speaker magnet - any other amp would be eaten alive), and
      • the BeoLab 5 [bang-olufsen.com] integrated amp (I've written [cross-spectrum.com] about the BeoLab 5 before).
      • Heck, even if you hate Bose speakers, try listening to externally-amplified Acoustimass-series speakers, and compare them to the internally-amp'd models - the self-amplified models sound much better.

    They'll be heavier than non-powered speakers because they'll need to contain an integrated power supply, an amplifier, and a microcontroller to do the interfacing. It's completely useless to bring up the "lossy speaker cable" argument, because if you were going to spend the extra money and waste an extra power cable for powered speakers, you might as well just use standard analog speakers with XLR cables (which have been VERY well established as nearly noiseless and lossless for point to point audio distribution). You can reliably have a couple double-shielded XLR cables ran from your pre-amp to your self-powered speakers for less than having speakers that speak IP.

    having multiple IP speakers on a network in the same room may also introduce phase offsets, since there's ALWAYS an inherent delay between receiving the network packets, decoding them, and sending the data off to DACs before the signal gets to the amplifier. Even a 2ms difference difference in delay/phase between two speakers in the same room is noticeable, and WILL screw up accurate stereo imaging. 2ms is not uncommon as a delay on an ethernet network.

    Of course, mixing analog and IP speakers in the same room is right out.

      Ethernet-level would have better latency than an IP stack, sure, but ties to back a platform-dependent transmission medium---you may as well use a speaker wire. And you have to write your own underlying network layer. If each speaker is running the same stack, it's going to have pretty much the same latency anyway---the worst problems arise combining digital and analog speakers.

      The advantage of TCP/UDP/Music-Transport-Protocol is that the medium suddenly becomes less relevant. Take wireless, for example. Imagine being able to cart your Big Speakers outside for a patio party without running a single audio wire. Or just to install speakers on the other side of your house (or in your shed) without having to grovel through the attic or crawlspace.

      Imagine how useful this could be for concerts: the sound board now has one wire running to it---the power line. Likewise with your front, middle and back stacks, and your monitors.

      Another plus is that we have a nice bidirectional protocol, as well as a chance for side-channel data: speakers can report their health back to the control panel, or to other speakers in the same stack. And since each speaker is doing its own DSP anyway, getting the equalization right for a given speaker is a matter of sending it a message.

      I'm sure we'll read about that in Slashdot sooner or later. If you don't catch the first article, you'll be sure to see the dupe.

      Airport Express.

      I know... it probably doesn't use TCP/IP, but it _is_ wireless...

      • Now we just need someone to write an "Audio Hijack Pro Airport Edition" so it can be used outside of iTunes...

  • The damn power supplies alone cost $800. How much does a pair of speakers cost?

    I have three computers in my office, three different OS's etc. If I could have one pair of speakers that I can plug into my switch and have all systems share would be really nice. (Assuming they opened the spec so someone would write linux drives for them)

    Right now, the only solution I've seen, has been to buy a mixer, but that would be more cables to string around. so I use three sets of $20 speakers...

    Wireless audio.

    No, wait, that's not new.
  • The catalog listings are a bit vague on what's running in the "speakers". Can I configure these to connect across the Internet to my Shoutcast server, then ship them to anywhere in the world with broadband, expecting them to just pipe in my audio? That makes overseas deployment and maintenance seem a lot more feasible for small companies who just need remote audio installers, rather than remote IT pros.

  • One question in my mind is how they get the delay to work...

    I can imagine mixing normal speakers and tcp/ip speakers and
    ending up with out-of-phase or echo problems if there are unequal
    delays. I could also imagine tv pictures out-of-sync with speakers.

    Anyone have any idea/experience with this?

  • So `cat /boot/vmlinuz >/dev/audio` is obsoleted ?

    I sometimes do that on my wife's laptop if she does not pay attention, or I am in the creepy mood ...

    ahm yes :) she refused winXP when I offered to put the original hdd with the stock XP on it back into the laptop :)

    more on the topic: somehow i do not see myself turning to networked speakers .... maybe my audio cables are just fine for my office/video room (6x7 meters) and my low-end sony DTS amp

  • This means that the music will be encrypted/DRM'd at the microphone and then routed to your speaker, but only if you've paid the RIAA thier extortion. Circumventing it will fall under DMCA as a felony. And don't give me the hacker crap of "The speakers will be analogue, so we can tap the signal there" - sure - You Can Do That, and fuck up a really expensive set of speakers AND set yourself up for a felony under DMCA. If Polk/Bose/B&W/Dynaudio/Infinity/Sony/Panasonic/et c . all get on board with this, it
