All the stuff came Monday and looks amazing

We are going to try to get some bread boards from radioshack for the xovers and pickup some 6" pvc for the mids if that will work idk how long of pvc to use for them.

Ok me and my dad are ready to start putting together the crossovers we just had one question. The components are very close together on the bread boards we found so we were wondering if any if them are going to interfere with each other? For example the coils. Heres a picture with them laid out on top of the board.

Need to separate the coils ( 200mm ideal )and re-orient at right angles to each other for best results

You think the bread boards are large enough to hold them all tho?

Skip the breadboards, Just use a scrap piece of MDF and drill holes to run zip-ties through to hold components down, and then once you have a final arrangement worked out and confirmed working correctly, glue all the pieces down to the MDF.

Good idea so if they are not big enough that's what we will do. Me and my dad don't have off at the same time so it's hard to get together with him and work on it I really hope we can work on it soon.

As others had mentioned, try to get your coils further apart so they don't wind up effecting each-others value. Rather that pile all the coils in the middle, try to somehow get them towards the outside corners or along the outside edge of the "board." You might also consider making 3 separate small boards, in order to isolate the 3 x-over segments, reducing complexity as you build since they will be physically separate not just logically separate.

I think my dad is able to move the coils to the edges and not have a problem he still hasn't gotten around to wiring them up although we did take the back and front panels off one to see what were dealing with and we definately have to change the fill. They have old orange fiberglass inside so he picked up some poly fill from walmart. We were not able to find PVC over 6" and the speakers are 6.5" but my dad found paint buckets that look like they will work as mid range enclosures. He wants to put the port on the top front, we don't have that much 4" pvc pipe left so we are thinking of just doing one shorter 4" port per box I told him with them being large boxes and having 2 10's that we might need to do 2 but what do you guys think? I am hoping 1 4" port will be enough tho.
