Building Your Own Speaker

[The Ogrady Roadshow 0]

right, well, i've been using a pair of wharfdale evps15s now for about 2 years i've replaced one driver but in the process i noticed that the crossover circuit board was a little burned should i say, the speakers don't sound bad when i'm running them with the bass bins (18inch MCcoy) but alone their not what they were!! the plan is to replace the speakers,crossover and tweeters, i'm looking at fitting eminence drivers & tweeters into the wharfdale cabs but not sure how to tackle the crossover.

 

so the question is has anyone ever modified a pair of speakers? what did you fit into them and did you make your own crossovers? is eminence a good way to go, thats whats fitted in the bassbins and i cant fault them! what do you think of the big plan? opions please!

 

Thanks Chris.

To be honest you need to take a serious look at your setup or the way you run things...

 

my old set of speakers never needed a crossover or driver replaced in there 3 years I used them and the guy who is now using them for the past 2 will not need to replace anything. that's 5 years of playing every weekend with no problems...

 

my 2 year old set of Speakers again go out twice a week and the only thing I need for them is a new rubber foot on a bass bin....

 

driver replacement would possibly mean your amp is clipping , burnt crossover means your doing something very wrong....

 

by all means replace all the parts but you should never have needed to do this.

Any chance of a detailed photo of the 'burnt' bits?

Some crossovers use high power resistors and these can run quite hot if the cabs are being fed a fair bit of power - this heat will be conducted down the leads and can discolour the board, making it look burnt when in fact nothing's wrong.

 

But if modifying the cabinet be careful if it's a ported design, because changing the driver can detune the system making it sound 'orrible.

 

Tweeter-wise, look at the recommended crossover frequency and buy a crossover designed for that, and the power levels you intend running it at. Building a crossover isn't actually difficult as such, but if you are new to this it's far better to buy a ready made one - they aren't expensive and getting the wrong one or building to the wrong parameters could put your tweeter at risk.

Hi

 

If only swapping drivers was that easy.

 

First , speaker cabinets are designed around a specific driver , so if you want to fit an eminence drive unit, build a box to suit.

 

Go to HERE and download the WinISD program ( its free) , next run the program and select the driver you want , this will give dimensions for a cab to suit.

I agree with DJ Marky Marc , if your crossover is burnt , there's something very wrong.

If you have some woodworking skills , and you want to build some awesome cabs , then check this out.

http://billfitzmaurice.com/ , these cabs are designed for the eminence range.

 

I would advise to buy the crossovers , there cheap these days.

 

Cheers

i can safely say that an eminence driver will NOT fit the wharfedale

 

we had one blown and the customer didnt want to fork out for a proper wharfedale one, so we grabbed an eminence from stock and it wasnt even close!

 

however it turns out that the replacement drivers are VERY cheap from wharfedale and cost alot less than the eminence!!!
