    what to do what to do

    tonight I was listening to some jazz when my sub started to shut on and off so I decided to check it out. well before I could get to it it fried. The thing that sucks that it just wasn't the components it was the circuit board that felt the brunt of the damage. It looks like I am on the drawing board for a new sub. I liked the sub I had it was one of the flatest responce subs in its price class but you know nothing lasts forever. oh well it seems like when you just get comfortable with a component it gives you problems. I can just be glad I was hear to keep the burn to the circuit board and not my house!!!!!!!!!!!!

    take a look at the Martin Logan dynamo at www.audioadvisor, it's on sale for about $450 down from $600. Its a real bargain for a non ported sub.

    Yeah I think it was its time for sure. If I would not have been there I think it could have been my walls time as well because it did not quit burning until I unplugged it. Oh well I guess I got 8 good years out of it so I can't complain too bad since I only paid about half of the retail price for it. But I just had other stuff I wanted to add to the system not have to go messing with a sub. Oh well such as life.

    Perhaps you can order a replacement amp for it?
    As for a sub, I would look into SVS. They offer lots of sub for the buck. Should be a big improvement over your JBL. Or you could go the DIY route (making the enclosure) in which case you'll have a LOT more options and a LOT more sub for the buck.

    yeah I am thinking about building my own subwoofer setup. Its something I have been wanting to do for a while but I was going to wait a while but it looks like blowing the JBL is going to speed up this process a bit.

    There are oodles of subwoofer DIY projects and you should definitely look into it. You could have a fine sounding sub for very little. Just need to put a little effort and time into it. Feel free to contact me about it.

    yeah I have been looking at the 1000 watt subwoofer amp from Dayton that Parts Express sells. I figure that if I went with an outboard amp then I could run two different sub enclosures so I can even my room responce out in the bass frequencies. I would just need to pick a woofer with a 500 watt power rating. Something like the dayton titanic or high output or high fidelety dayton woofer would probably do it. Or possibly see what their next sale brings on a high power woofer. But I have heard good things about the dayton high powered woofers. Any other brands to look at let me know

    1 plate amp to power 2 subs is not the best (practically) but I guess you could do it.
    The best is first to look at different drivers and ideally look at how they model according to different enclosure types (sealed/ported)and internal volumes. There is a program for this with which you will learn a lot just by typing in subwoofers' Thiele/Small parameters and then getting an idea of their theoretical frequency responses with respect to the type of enclosure they will be in. You can download the program from here:
    http://www.linearteam.dk/default.aspx?pageid=winisdpro

    Have a look at the following web-sites which feature quality subwoofer drivers:
    http://www.diycable.com/main/default.php
    http://www.soundsplinter.com/
    http://www.tcsounds.com/
    http://www.rythmikaudio.com/

    If you have any questions just ask.

    no I was not planning on using a plate amp. they make subwoofer amps that are stand alone units and I think this is better for a couple of reasons. One is the fact that everything is seperate so if you have any problems with anything its all easier to work on or replace. and two I believe that having the amp outside of the sub enclosure allow the components in the amp to run better without the vibration of the components and the enclosures would be better sealed with just a woofer,port if needed, and speaker connector and not having a big plate amp in the enclosure.

    Yeah I have that program and I have run most of the subs I have been looking at through it and it looks like there are a lot of options for me since I really do not have the space limitations that some people do. Most of my concern would center around flat responce and overall musical ability since music is of more concern for me than theater.

    In that case one of the Rythmik Audio servos may just be up your ally! There are 12" and 15" versions, both sealed designs, servo controlled by the amp. Check out the website and read up on the customer reviews
    If you want to go a little cheaper, the exodus drivers should also be very good, you could mate them with a normal plate amp from partsexpress.com
    To be honest all of these drivers should perform extremely well given you have the correct enclosure. If you need any ideas let me know.
