    I picked up a pair of wharfdale modus drivers these are small nominal 4" drivers with a full range performance ... £4 each

    On a second whim I bought 5 x 3m lengths of 120mmx18mm floor boards for £17 [the cheapest timber I could find ].

    I used these to construct a 900mm x 240mm x 150mm box with a 85mm x 120mm port at the bottom front. The drivers were fitted about 80mm from the top of the front panel. A baffle was fitted inside from above the port where it touches the front to 100m short of the centre of the top of the box so as to form a folded tqwt.

    internal wiring was something I got lying about and the speaker terminals were the cheapest maplin do.

    sound..... bugger bugger bugger my wife wants me to get rid of my statics

    fortunately there not quite that good ...and have a very different touch on the music and my build quality is rough.

    Can you publish any plans for the box. Looks very interesting.

    Nice contribution Pete.

    Are the Wharfedale drivers the ones from ebay? If so I have a pair of those too along with other Whafedale bits and bobs like bass drivers out of the Valdus 500, mid/bass out of the Diamond series and a couple of tweeter from models I'm not sure about. For the money (a few quid each) they're brilliant drivers, much better than most of the budget stuff.

    Another nice buy if you need to extend the top end and gain better power response is the 3/4" Audax titanium domes that are always on ebay. Cross these around 4Khz 2nd order and they sound great.

    I lifted the generic plans of a far east forum ...I can't claim credit for them ....but I've modded them slightly as you can see from the sizes to fit my timber.

    sounds like there the same drivers ...might dip in an get another few pairs ...as expect they are limited availability.

    actually the jordan jx92 what its name...may be used in a visaton full range rear horn plan I have.

    hi jimbo

    ...did you build a cabinet for them ?


    These speakers are just getting better as the drivers run in .....there now starting to do a bit of bass...

    latest mods to the cabinet involved an insence stick inside the main chamber hunting for leaks ....a couple minor ones blocked with silicone seal ....

    I also chamffered the drive unit hole on the inside to allow a clean propogation of the rear wave ...I used a dremel sanding cylinder thing .....not pretty but effective.

    I then sealed the drivers to the cabinet with a small ammount of silicone .

    Wow, that looks like exactly the same gas fire as was in the house I grew up in... both sets of speakers look good too ;-)

    So for a complete beginner, how did you slice the boards to length and how are they fastened together?

    Thanks,

    Dr. Matt...

    How does that work - do you see smoke chuffing out on the dub reggae tracks, or do you work on smell. Come to think of it - it should suck as much as it blows :confused: ;)

    I went for the Aurousals in the end. Piano gloss black, so not worth me building them for the price i got them. Pop in one day and have a listen. Jim.

    would love to.......I'll be in touch

    building the speakers ......

    as the wood was 18mm floor boards I placed two cut lengths for the side together and liberally glued...repeated four times
    the front baffle had the tongue removed but not the groove on the other side ...a mistake so if you use floor board cut that off ..

    I used a black and decker jig saw with a straight edge clamped to provide a level cut.

    What do you think of the Aurousals Jim?

    What do you think of them in comparison with similarly priced kit?

    I've got anambition (when circumstances allow) to build my own...but am interested in these too?



    :)

    That's a fantastic diy effort. Gold star for that man. I've also got a pair of jordan speakers and wouldn't hesitate to recommend them

    Hi David
    They are very good as in detail and set up properly surprisingly good bass for the size. They would be perfect diy speakers. Jim.

    Try polyurethane wood adhesive - it expands as it dries plus some sash clamps to hold it together as it dries. Disposable gloves are a good idea as it's very sticky and not skin friendly.
