    Ran across the URL in another thread and wondered if anyone had built any of the speakers from the kits they sell? They've got plenty of letters of endorsement on there, but they could've written them themselves.. :clown:

    Was looking at the A2 kit specifically, but any comments would be appreciated..

    Do they sound any good and what sort of speaker range/price are they akin to..?

    PS. What's the difference between 'Transmission Line' & 'AV/HiFi'..?

    :confused:

    :D

    The Transmission Line range of speakers use a different techniquie to vent the sound from the back of the drivers compared to a standard port.

    Quote from http://www.diysubwoofers.org/tls/

    "The transmission line system is a waveguide system in which the guide reverses the phase of the driver's rear output, thereby reinforcing the frequencies near the driver's Fs. Unlike sealed, ported and bandpass systems, transmission line systems are theoretically non-resonant, and therefore are capable of producing very clean and uncolored bass - if done properly! The transmission line system affords uncolored sound due to the lack of system and cabinet resonances, provides extended bass support, and all at moderate efficiency."

    The transmission line speaker is more complicated to design than normal sealed or ported speakers but this is already designed for you. Building the speaker is a little more complicated as well because of the wave guide so it is not used commercially expect in highend speakers. If your unsure which speaker to go for email IPL, as the previous post states they come highly recommended in these forums.

    You cant go wrong, your money is paying for decent components and design in the speaker.

    I'm not really convinced that you can save that much at this end of the market, if indeed you can really save anything at all.
    Economies of scale mean that the established speaker makers can produce some very good stuff at prices you'd struggle to match, even DIY.
    Go higher end though and the makers lose that economy of scale, and their prices start to ramp up quite steeply - if you are careful, you can certainly match or better these type of speakers for less money.

    However, (and it's a big caveat IMO), you won't know what they actually sound like until you've finished them, unlike premade speakers.
    Also, unless you are a very good DIY cabinet maker, you'll struggle to match the finish of many premade veneered speakers (true, that doesn't affect the sound, but we all have to live with speakers in our living rooms etc).

    IMO, the best area to make savings by DIY is with subwoofers - you can make a very decent subwoofer for a fraction of the price of some of the established makes, and much better than the budget units available for similar money!
