PD2150

Anybody know where I can get cabinet plans for PD2150 drivers.

You will have to decide what sort of cab you want. I.E. horn loaded, reflex, band pass etc. If it's a reflex cab you want, you could decide how large or small you want it to be, and then tune it accordingly.

Yes, I guess the question was a bit lacking ! I`m looking for a reflex design - I intend to use them ( I have 2 ) with a Bass guitar 5 string. As for tuning I don`t really know much about that sort of thing, I understand port size and length and also volume all come into it but that is about all I know so I`m looking for some cabinet plans which have already been tried.

I assume you will have something above the 21's in the system. Also, the cabs will be quite large. Reflex cabs are easy, so bearing in mind the size of the speaker, tell me what size you want the box and I can tell you what size to make the ports etc. you don't really need a drawing for a square box. just sizes.

Yes I`ve got some 10 inch for the top end. I think I`m correct in that the low B is around 31 Hz, so whatever is needed to get that low properly. I will use 2 seperate cabinets. Give me an idea of how big they need to be from that and also how flexible the length and so on can be given the same volume.Thanks for your help.

From memory, I used around 400 liters for the 21. work out your ideal dimensions from that. I only ever built 21's with 25mm ply. that's something else you will have to think about.

BP Sound has some very heavy duty Cray cabs that may suit?
I know he needs space..
