I'm in the process of designing an active subwoofer, I'm using a HiVi SP10 subwoofer which requires a very small enclosure. Meaning the subwoofer's huge magnet will be an inch or two away from the power transformer (toroidal) on the amp.

Will this cause any problems?

Any reply will be a great use, Thanks

Welcome to the forum Snufflycube.
I would test it out first. Attached the sub to the amp and bring it close to the toroid to see if you get problems. Better to find out before you built the enclosure. Try keep the speaker wire away from the toroid and twist them tightly. Let us know how you make out, I am curious to know too.

Also, here is a link to Adam's DIY HiVi SP10 Subwoofer Project.

Cheers, Gio

Thanks for your quick reply Gio. I will be receiving the sub soon, yet wont be getting the amp for a long while, So I have no way to test it. But just to be on the safe side i will increase the box volume to have the sub as far away as possible. around 1.1 cuft

I know this thread is just about transformers but Adams link you sent me got me thinking. Adam used 1.5 inch MDF on his ported enclosure, meaning not much pressure exerted on the box, I'm building a sealed enclosure so the pressure will be a lot more, Yes?

What thickens should I use? 2 inch all round and braced

Thanks alot

Dan
