Building your own speakers

Considering building my own speakers for my home audio/PC/decks setup.

Is this actually good value for money compared to buying them seperately?

Doesn't need to be overtly loud, but nice and crisp sounding, basic tweeter/mid-range/sub in a single unit x2.  Running at ~200w I reckon should be plenty.  Will be constructing a straightforward MDF box for them.

Where is a good place to buy parts?  I though about Maplin but they tend to be pretty expensive.

(might even build an amp too if that isn't too difficult?)

    Building your own speakers isn't too difficult, but building an amp is a whole different matter.

    As for drivers, there are plenty out there.  How much cash do you you have and how much space?  One of my favourites is the EJJordan JX92S which would save you all the problems around building and testing a crossover.  Very nice in many respects.

    Cool- I'll stick to a second-hand straightforward DJ/PA amp then most likely.

    For the speakers- I guess I don't want to pay more than £50 for the pair (components).  Need to spend more?

    How much is that kit you're linking to?

    I'm a festival virgin, was pretty good though, but was with mostly couples, would have enjoyed it more with more of the lads lads !

    The women there, fcuk me, like models some of them!  Fat, chavvy women were very much the minority which isn't usually the case on a night out.  Loved the festival atmosphere, really laid back, everyone getting on!  Krafty Kutz, GLC and Stanton Warriors were all great.  I'll post some photos when they get put on Facebook!  (PM your Facebook name!)

    Considering you can pick up excellent speakers cheaply either 2nd hand or from somewhere like Richer Sounds, why on earth would you bother?

    Fun, personalised and more cost effective (in theory!)

    Ah yes of course, fun....

    If you're handy with a saw etc, then I guess there is some level of satisfaction to it.

    I was painted up bright red, face, arms, everything, with a mask on so chances are he'll have seen me!  I spent a lot of time drinking/smoking up at our pitch than I did in the arena to be honest.  Good experience, I'll go again, but a bit more prepared next time!

    I've built speaker cabinets, for guitar amplifiers primarily.
    I've done around 20 over the years, for myself and for other people.

    It is a fun project but unlikely to save you money unless you are already kitted out.
    Once you buy your tools, materials and factor the labour and a couple of mistakes it will definitely be cheaper to buy something from Richer Sounds.

    That said, I completely support your decision to do it yourself- you will learn a lot and have a cool (albeit geeky) skill.

    Why use MDF?
    Why not use birch ply?
    It will sound better.
    MDF is easier to finish, but it is lazy carpentry imho.

    If you have any questions just ask and I will do my best to help.

    For the last year of studying I choose to base mine on building speakers...or at least a set...was prob them most fun year of my life, tho I go carried away with the complexity of the design and components used....



    Kinda initial design

    Speaker components...tho spent way to much on Yamaha ones...





    First basic shell...



    Then the cloest to finished pics I could find...sadly I cant find the ones when they where smoothed off at the edges, then glossed so they had a shiny/ vanished look...





    Would love to give this another go givin the time...and...ehh..money...

    They look great!  My design will be a very simple box-shape though!

    Cu3ed, any places to buy a 3-way crossover?
    Only one I've seen is in Maplin, but I don't know what will make a good or bad one!?

    For the speakers- I guess I don't want to pay more than £50 for the pair (components).  Need to spend more?

    How much is that kit you're linking to?


    If you're going to use an amp like that go and test it first.  I've found that the levels on the channels don't always match up, which is annoying if one is a dB or two louder.  Same issue if they have volume controls on them, the knobs are often unmatched which is a pain.  If you're using an external main volume control and have a good balance adjuster though this wouldn't be an issue.

    £50 for a pair of components is a very low budget.  I'm don't know much about that end of the market.  The ones I linked to used to be about £125 per driver, but they might have been updated since then.  They're nice and simple to build for, and good quality which is why I suggested them, and you wouldn't need crossovers or additional drivers.

    26 They look great!  My design will be a very simple box-shape though!

    Simple box shape will be the best, it's the easiest to get a nice finish on.
    3 way active I presume?  Something like the cx2310 by Behringer might do.  I'd usually say go for 2 way though, and with the power levels you're talking about a two way passive would be the most effective, in which case you would buy it with the drivers.

    Edit:  Just checked the link - an off the shelf three way passive filter!?!  No, just no!  You need to match the components and the drivers carefully, which should take into account not just the drivers but the enclosure as well.  People get paid a lot of money for designing good passive crossovers.

    Cu3ed - did you go to uni in Wales?  I'm sure I saw those speakers at an end of year show?

    A true 200W set with even halfway decent drivers will not be cheap, for £50 you can pretty much forget it. Budget something more like £300 or more if you want something that can truly take 200W and be of good quality. Building a 2 way a *lot* easier than a 3 way... and be cheaper...

    Mouser is talking a lot of sense about the crossovers, generic 3 way passive crossovers will be ****. Crossovers have to be matched to the driver pair to be any good.


    My honest recommendation would be to go to Richer Sounds and buy a pair of decent 6" 50W RMS drivers, and a basic amp to go with them...

    As a bit of a guide, the last thing I did (several years ago now) was a full surround set using 6" drivers. They were comparitively cheap driver units.... but the total cost of drivers, crossover components, and a few sheets of MDF came to around £1200...
