Ported vs sealed 2 ways

[plasmodium]

I was hoping some of the learned would offer me some advice....

I am about to build a pair of two ways using vifa drivers
d25ag35-06
p17wj-00-08
the plans I am using call for a 23.5L ported enclosure

I have read on another site that diy-ers are better off with sealed boxes - more room for error etc

what differences would be caused by using a sealed box..... should it be a different volume to the above?

If anyone can point me to some good sites about this issue I would be grateful. cheers

nearly forgot.......

would the xover need changing if a box was sealed instead of ported????

cheers

not sure if i classify as learned but i'll reply anyway.......

firstly, the drivers - I've used these and they are both decent units. you might want to consider the D27TG as an alternative tweeter. i prefer the sound personally, and i think its a little cheaper (could be wrong there tho).

as for the sealed versus ported, i wouldn't say vented boxes are any more difficult for a diy-er. there's just as much margin for error in the volume too - i find it best to tune the port by ear by changing the length until i get the bass response i like. some people seem not to like vented boxes because of low frequency transient characteristics and things like that, but for a two way i personally think you're better off with an extended bass response than worrying about phase issues too much.

for a sealed box your volume would need to be different. there's plenty of freeware programs which will calculate this for you.

hope that helps.

And if you do decide to go with a sealed enclosure, you won't need to modify the crossover. I've paired two P17WJ-00-08s with a D25AG35-06 in a ported enclosure and I really like them alot. Hope your project works out well for you.
