    Hi,
    I stick my nose in this forum every now and again to see how all the lunatics are doing and also to ask a silly question or two!!!!

    I can possibly pick up a used Behringer Europower EP1500 for a good price but I'm wondering if I should or not.

    What options would this amp offer a first time sub "DIY"er?

    I'm thinking of keeping it simple and going for a single 15" driver sealed sub.

    To be honest I've been putting this project on the long finger for years but if I had an amp it might motivate me to get busy.

    Thanks in advance for any advise and info.

    It should have the balls to power a single 15 with ease so if you can get it for a good price then go for it.

    Thanks for the reply swiftpete. What would be a ballpark fair price for a secondhand EP1500 in "excellent" condition?

    Watch out for the noise, apparently they all sound like trains so need to modify a new fan into the insides, quite easy by all accounts but just so you know

    I was aware of the noisy fan and would change it ASAP.

    Also, it seems I have access to some of the steel ducting that I've seen some members use for a "sonostube" subwoofer which is a bit of a result.:hiya:

    Would the EP1500 be up to driving a single 18" driver?

    According to DV247 they are now discontinued. The EP2000 would be a better bet personally. That is rated at 2000 watts into 4 ohms bridged. I would half that for RMS power.

    I'm looking at a secondhand EP1500, just trying to understand where it limits lie when used with a DIY sub.

    What 15" driver will you be using and will it be ported or sealed? This will make a difference with how much input power you apply.

    Cheers, its very early in the planning process and still trying to figure out what approach to take. In my first post I was going for a sealed box but now I'm thinking a sealed or ported cyclinder as I can get some spiral ducting off a friend of a friend for peanuts!

    The sub would be used in a dedicated room mainly for movies and games so I'm thinking decent output at below 20Hz would be something to aim for.

    As for the driver, I'd be looking to get one of the Fi Q drivers that are recommended frequently on here, 15" or 18" if possible with the EP1500.

    Thanks again for your input

    Thats very decent of you, thanks.

    Are there any other 15" or 18" drivers worth considering in the Fi range available from BladeICE?

    Right here's a start.

    Here are two simulations. One is a Q15 in a 6 cu ft (170l) box(cylinder) tuned to 17hz and a Q18 in a 12 cu ft (340l) box(cylinder) tuned to 17hz. Both with 1000 watts input power.

    The Q15 has a 6" port 39" long and the Q18 has a 8" port 33" long.

    It gives you an idea on the different sizes between the two. The Q18 will need a fairly big box/cylinder.

    Cylinder subs are not my cup off tea but it gives you an idea.

    Here's a simulation to show you the difference between sealed and ported.

    Blue is Q18 in a 170l sealed box. Qtc 0.671 and 1000 watts input power

    Pink is Q15 in a 60l sealed box. Qtc 0.648 and 1000 watts input power.

    Thanks for that joshua2005. My chart reading skills are a little bit rusty to say the least, but am I correct to say that a Q18 in a 340L enclosure is possible....:confused:.

    To my eyes the graphs show serious SPL all the way down to 17hz where it starts to drop off. Am I onto something that is actually feasible?

    How high would the tube have to be if it was a 24" diameter tube to get approx 340L?

    24" internal diameter would give approx 1.2 metres internal height
