Hi guys,
I'm Seb and new here and to the world of DIY audio. Sorry if this wasnt the right area but none of the others seemed right either.
I have a project, and very little understanding of how to do it. Two years ago in boarding school I savagly attacked a pair of speakers i owned, crammed the drivers from both enclosures into one enclosure along with a car radio and a 12v LiPo. Believe it or not it worked, but the cheap amp I used distorted quickly and the speakers were choked for space.
So my project is to redesign from the ground up. I want to keep the drivers as they have been with me a long time and have some amazing memories but other than that I am willing to completly replace. I don't have a huge budget, but also don't have a deadline so if I can't yet afford something I can simply save.
I am CAD able and have a well equiped workshop at my disposal. My plan was to design and order a custom pcb and solder up my own amp (with inputs, potentiometers and bluetooth). My problem is I can't find any information on my drivers. The drivers are from a pair of Wharferdale Laser 80s and I can give more info if needed.
My basic question is how to work out what AMP would work well (to power the drivers well and run off battery power (I read that I should look at lead acid rather than lithium ion?)) also how to work out acceptable enclosure dimentions (I don't want to sacrifice fidelity but also dont want to sacrifice portability). Lastly, how can I design a crossover? I read that its dependant on the enclosure so the ones I already have from the original speakers won't work. But how can I design and build my enclosure before knowing where my crossover will be and how much space it will take?
Sorry for being clueless, figured I'd ask rather than continuing to try and learn on my own.
Thanks
Seb

Hi Seb, no, the crossover is not dependant on the enclosure but on the drivers, so you're ok.
Well, there's a little to be said about it ( the radiation from full space to half space and so on ) but since you said it will be portable ( i.e. quasi- full space) the original crossover filter will be ok.
The woofer chamber should be the same, either.
