I would do a 10in port for an 18, I'm gonna use an 8in for my dd 2515

Just switched out my 2 6" aeros for an 8". Just fixed my 18 a few minutes ago though so havent gotten to try it yet.

1 8" > 2 6's. Single port is more efficient both acoustically and space-wise. To achieve the same tuning with 2 6's you would need the 2 6's to be longer by a couple inches. Plus you can just pick up an 8" sono tube from lowes/hd for like $5. And for an 18 I would use a 10" port.

Hm.... **** a 10 inch port seems so big for 1 18

I gues im going to try out the 8in port to see if it makes a difference

8" port = ~50 in^2 of port area. 10" port = ~79 in^2 of port area. A 10" port is about the max I would use for an 18 if you wanted to do a daily setup that wasn't too peaky. If it was a slot port I wouldn't go over around 90-100 in^2 of port. An 8" port should be very musical though it might not have the loudness you're looking for, in which case you could bump it up to the 10".

Personally I would keep the dual 6" setup, if you have access to a cheap way to try out a single 8" port then go for it, but you will likely have a drop off in "SPL" in most cases but not all.

However, a single 10" wold be a nice setup and would be very fun to play around with if done properly.

The real issue with flared round ports and output is that there are many different views on it. I don't know to many people that actually agree. Most result to testing and then just use what works best your particular application.
