Keymaster@schurter may I recommend you upload those as pictures versus attachments? It allows us to flip through them without having to download them.
As for the stain, I haven’t used that Verathane before? Have you used it successfully on that plywood? I only ask because Pine is not the easiest to stain evenly. I have had very good luck with General Finishes Gel Stain on pine before. You can usually only buy it at stores that specialize in woodworking (ie they aren’t sold in big box stores). It is high grade stuff and a little goes a long way. Anyway, it is just a suggestion if you have not used the Verathane and know it works well with this material. I don’t even know if General FInishes has a color you like.

ParticipantYes I will, I thought I was uploading them , I can see them on my side when I open the thread.
Feel free to have any suggestions, very open to feedback !!
The stain i have used on my devastator that’s about 3/4 finishes on the same wood. Driver is backorder.

KeymasterOh good. I know sometimes certain things don’t do well with pine. That’s good to know that the very thing works well. I might have to try it sometime. I went ahead and updated all of your threads to pictures for you. I did that last night. All is well. I just wanted to give you a heads up. You’re putting a lot of work into this thread and I just want to make sure people can fully appreciate it.
I’m so disappointed that those woofers are on backorder. They have an incredible distortion profile. Some of the best if not the best that I’ve used in this size. They are very clean sounding. Did they give you an eta?

ParticipantParts Question
Going to place my order for the xover parts ,
Dayton Audio 0.90mH 18 AWG Perfect Layer Inductor Crossover Coil – not in stock , can I put a 0.7mh and 0.2mh together , or what ever equals 0.90 ?

KeymasterYou can combine, but layout on the board becomes a little trickier You can go with the 20ga if the 18ga is sold out or use that McBride you linked. Either will work for this purpose.
