building a sonotube enclosure, need advice
I've built a sonotube before for my old old fosgate 100w rms sub. it was sealed and didn't sound too bad. not the best setup and not the most powerful. Now I'm building a new system in my newer car. I got a 10" Alpine Type R (1021D) sub and plan to power it with around 300-500w RMS. I was thinking because this setup is quite powerful I need to build it ported. I was also thinking of maybe spraying the tube with something that will give the sonotube walls more rigidity. I want a sonotube due to space and weight.
Anyway I could use all the advice I could get right now so please post away on the topic. I'll be building the tube next week.

I wouldn't suggest using a sonotube for a sub enclosure...If you're strapped for space, why don't you build an MDF enclosure (10 x 10 x desired length) for the 10" sub?
If you're stuck on the sonotube idea, I guess you can put a few layers of fiberglass resin on the inside...

Well I already got a piece of sonotube that I used for my 12" before only this time I want to put more time and effort in it. Last time I bulit it in a matter of like 3 hours all carpeted and stuff. But it looked like s#!t and probably was leaking in places. I want to go with volume recommended by alpine for ported enclosure and then cut out the end caps to consist of 2 pieces per side glued together where one sits tight inside and the top part sits flush on top of the tube.
What size port I should go for, for best results? I want to get nice tight, precise but deep bass out of it. Would a simple straight port work fine? or do I need to maybe curve it inside somehow? Because I remember seeing one like that long time ago.
