    Tube Subwoofers...

    Ok I ran a but didnt get much. I heard some people saying they didnt like them. I am curious are they any good. Most dont seem to be high RMS wattage either. I am asking cuz a friend of mine could hook me up with one but I dont think they are as good as a normal woofer.

    Also, is it hard making a enclosure for a normal subwoofer?

    I am new to car audio but am big into stereos and music quality, thanks.
    Thanks.

    Naw, just make sure it's the right volume for your woofer, and seal it up proper. I had a tube sub for a while, it was basically a round band-pass box. Sounded ok, but only had an 8" woofer in there.

    My bro has a 12" tube, and it is LOUD. I guess it depends on design and quality. Though I think all sealed boxes have a cleaner sound than tube, vented, or band-pass boxes.

    Its like anything else, there are good ones and bad ones. The bad ones suck and the good ones rock. If you spend the money and have one properly designed for THE speaker you are using, it should rock. Unfortunately most are just a shotgun design made to "fit" just about any woofer. Talk to someone with bassbox pro or a similar program, and get the spec sheet for your sub. From there you can design a proper enclosure. An off the shelf one from KMart will suck.

    Speaking of off the shelf I just saw this.
    http://www.overstock.com/cgi-bin/d2....PROD_ID=661440



    Metrik 12-in. 480-watt Powered Tube Subwoofer
    Features include:

    * 12-inch tube speaker with amplifier
    * 300 mm paper coated cone foam edge woofer
    * 480 watts peak power
    * 120 watts RMS
    * 20-200Hz frequency response
    * 80-120Hz(adjustable) outlet
    * DC12V-14.4V negative ground power source

    I never heard of the brand either. One of my friends is looking for something for his 98 Ranger XLT. He needs the back seats parts of the time so wouldnt a tube woofer fit his needs? Because arent they able to be taken out quick/easy?

    For me, I think I will just stick to a normal woofer.

    Thanks for the help/info so far guys.

    yea, that 480 watts is BS.

    anyone that has ever owned a Orion 225 hcca amp (2 channel 25w per channel, I had 2 ) knows what a TRUE 50 watts is. And its no joke! Their 480w is "creative math".

    I never look @ peak anyways, I know better than that. But hows the RMS tho? And does anyone know the answers to my other questions?

    the answer to your question is right there: "Most don't seem to be high RMS wattage". so regardless of the shape, the bigger, is the better.

    no, well depends on your previous skills. can you follow measurements? can you cut a piece of mdf in a straight as possible line? if you have lots of guts then you can sure able to built one.

    i build my own sub (check the pic). it is a cheap 10" 130wrms in an airtight enclosure. with the correct volume i managed to make it sound really good. i can adjust the volume of the enclosure to accomodate a tube exhaust which can add 2db of loudness but i prefer the solid sound of an enclosed one.

    Thanks for the info. I got a radial arm saw. Most ppl who work with wood probably have one. Think mitersaw but where the blade and handle part slides forward. I can make perfect cuts @ all degrees unto like 2 ft wide, plus it converts to a table saw w/ the saw ontop tho.

    Where can I figure out how much volume and the specifics I will need? Do I get it from the speaker manufacturer? Also, will a fully enclosed one give good "punch"? Or will I need a port on it?

    Any help is appreciated.

    How good are you at math? This page: http://www.diysubwoofers.org/ has some formulas to help you get the right dimensions for you subwoofer. Bear in mind that you need to pick out your woofer cone first so that you can use the woofers specs in the calculations. Once you have your dims you can cut your wood and start putting it all together.

    Ported vs Sealed is entirely up to your preference. Ported will use a lot less power but you'll be giving up sound quality. If you can affored more power, the sealed generally sound better. Your results may vary and everyone has a different opinion.

    I read through alot of that stuff but theres alot to learn, lol. Well my uncle is a audiophile and knows about construction so I guess my best luck is just to ask him.

    Also, danon why didnt you put carpet on your sub?
