Soundsplinter RL-p15...port surface area?

[MOState]

Hi there, first post on this board. Im building a coffee-table/speaker. I plan on putting a Soundsplinter RL-p15 in there with a Behringer EP1500 on it. Im going to be giving it 4.5 to 5 cubes, tuned to 16hz. Obviously I don't want this to be a HUGE table...which brings me to my question. Im torn on how much port surface area to use. Obviously I don't want port noise, but I'm also slightly limited on space. What is the bare-minimum surface area I should be giving this/these ports? I was contemplating using If I use PVC I don't know whether to use 1 or 2 ports. Im assuming 1 4" PVC pipe is not nearly enough...so I thought about 2. Im also debating on making a slot port...again I don't know how big. Either way, I plan on beginning construction on Tuesday.

I also have one more question. Im building this out of MDF, and I was planning on using a black lacquer to finish it. What kind of primer/sealer do I need to use to obtain a good finish?

Thanks for any help,

Shaun

If you look at the numerous threads where people are building ported subs with the RL-p15" you'll find that the smallest recommended port is 6" diameter.

If you model whatever size box you want to build, you'll find that there's a problem using doubled 4" ports. They get really long.

Personally I wouldn't use a slot port with a high excursion driver ...

There are probably a 1/2 dozen recent threads on this forum dealing with applying a gloss or piano black finish. A search will find them....

Post #10, this is how i went about the piano gloss finish, and it has worked well. Hopfully it treats you the same way
