    Hi again folks,
    I noticed an interesting advert in HCC by IPL acoustics who supply subwoofer kits to build yourself. The kit prices seem very reasonable but i suppose that depends on what the end product sounds like.
    Has anyone ever tried to build their own?
    What were the results?
    How difficult is it?
    Please let me know your thoughts,
    Regards,John.

    go this this site if you haven't before and checkout the "diy and advanced projects" section. They are mad about building their own subs and are very pleased with them. They havn't tried the IPL kits (i think) since they are in America. But loads of useful info on the area in general.

    IPL Acoustics is a UK company (Devon) the sell a subwoofer kit 10 inch sub and a sealed box, but it uses equaliation to get good sounding low bass from a small space.

    It is good for music or movie use.

    I am probebly getting one, they have had good reviews on this forum.

    I notice from their site that speaker kits come '' with dual terminals for bi-wiring (except A.V.)''. Why would the AV speakers be minus a bi-wire crossover??

    dual terminals on a sub usually mean its got a stereo voice coil - you attach left and right speaker cables to it . in av use the .1 is a mono signal, so you`d drive both terminals in parrallel (or series if they`re 4 ohms each.)

    i reckon.......

    One of those kits would certainly be an "easy" way to build a DIY sub - I'm looking into it all too, and there's a lot to consider if you want to start from scratch.
    If you don't have the tools/space/skills/time to accurately cut all the materials yourself, one of the kits may well be a good idea.

    They seem to imply that it is all AV speakers not only subs which feature this design of crossover.Point i was making was why design the ''Hi-Fi'' speakers with a bi-wire crossover but none of the AV designs?

    I built my own sub from using 2 kenwood 300w 10" drivers and a custom made box. Then built a 40Amp Powersupply to drive a 140w mono ALpine amp via an active xover. Run all this off the sub preout from the Receiver and have a good solid solution to LFE.

    Its cheap as i had all the bits for the job and sounds pretty good too.:D

    Only just noticed this.

    The IPL sub is a good one by all accounts.

    The sub I've built would probably be a little on the large size for what you want, uses a 15" Adire Audio Tempest driver. The sub is around 0.5x0.5x0.85m in size. It's too big to be practical but does reach down very low and is gret with music.

    I'm going to build a new smaller nice and compact sub for Uni. use should be about 0.3x0.3x0.4m in size using twin 10" JL drivers.

    Retro - where did you get the Adire drive unit from? I had the feeling they could only be got from the States.

    You can get them from the UK distributor who is GaryG on these forums.

    I think he usually has the Tempest and Shiva's in stock.

    garyg@adireaudio.co.uk

    I think, I have not got his email address on this PC.

    I have a pair of KEF THX AV1 subs which do give a nice bass output. I have built many boxes for ICE installs, infact, just did one yesterday for my brother inlaw, this housed a pair of 12's with a total internal of 3 cuft.

    What size box does the 15 need and what sort of freq response could you expect? Am keen to see on paper what a pair of 15 would do for my HC.

    Hi.

    Tempest Applications

    Expect high SPLs, very low extension, tight bass.......and a large enclosure.


    Cheers

    From reading all of the IPL threads 18 months or so back, I seem to recall that that the results were very good. The main thing you need to do is ensure you seal the box properly when you build it.

    I don't think there is much doubt over the quality of the components. The driver is solid and from all of the hints on IPL's website, the amp/crossover is made by REL's supplier.

    I'm seriously thinking about IPL's new SW3 kit (REL Storm clone by the looks of it).

    HTH,
    Joel

    WOW. This is an old thread (over a year old), I have had a IPL Acoustics SW2 built for over a year now, It is a nice subwoofer, very simular to a Velodyne CHT 10.

    The newer SW3 does look like a pritty nice subwoofer, It should be even better than the SW2 it has a larger enclosure and better subwoofer driver.

    While we're all here, the RTP-15 was finaly created this year! It was made up and running by Mr Taz who had the chance to run it in for a few months while i was away at Uni.

    Had it running at home for a few weeks now and it's doing a damn fine job. It's partnering a pair of Acoustic Energy AE100i SE speakers and basically providing the bottom end of a 2.0 system running of my PC. The AE's are powered by an Arcam P75 power amp.

    For more info see: www.retrotaz.co.uk :)

    Yes. If you have any questions, fire away.

    Just for clarification as this thread has been resurected, I'm no longer the UK distributor for Adire Audio.
