Audiopulse Epic 8" Enclosure Questions

[audiophyle_247 2]

I have an AP Epic 8" sub coming in the mail from Mike @ soundsplinter.

I have yet to ever hear or play with these and want to know what others have had good results with.

(enclosure size, tune freq, port area)

ask ///M5 about his rl-i8 enclosure. that would be the berries for your epic. damn near the same driver, if not the same.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

small enclosure requirements equals a pretty long port lol.

it is fun making a slot port box for them while trying to limit the amount of turns in the port.

///M5 on here very often?

Any links for his build?

[mrray13 30]

he's on here daily. just drop him a pm, he'll give ya the specs. basic rundown....

gross enclosure size was over 3.5 cubes, because of port. net size was well under one cube, lol.

my sealed box for my rl-i8 is .17ft^3 net. box barely big enough to hold the woofer. IIRC, ///M5's ported box is .65 net. which is in the ballpark.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

mrray13 what do you think of the sealed .17cuft box?

That is almost ridiculous in size.

thats all it takes for one sealed

you can put two . 5 cu. ft. ported and get a good response only prob. is it needs a port like 75 or so inches long.

iirc with the motor having such a high bl it will not require a large box, i may be mistaken on this.

You have a PM, but I'd also add on the sealed front that .2 is too small. I would pick to do around .4cuft a piece (at least for the Rli8, which I would venture to guess will be really simliar). I had mine in .3 and .4 and much preferred the .4.

[audiophyle_247 2]

AP site claims .5~1cuft for sealed, and .8~1.5cuft for ported, which is so far larger than anyone has used or recommended thus far.

Thus the need for getting feedback.

Hmmm....those specs sound about right for a 10''. Seems a little big to me for an 8''.

[mrray13 30]

the .17ft^3 sounded just fine in room, more then enough for the power it was getting. in car was a bit different, although it still works. will the larger ones ///M5 suggested work better? i'd lean towards yes, he's a bit more anal about sq then i am.

the biggest ported i built for the rl-i8 was 1.25ft^3@35hz. i can't remember port size though. it got very loud, and even took 1700wrms for a bit, but was definitely peaky. to be honest, .65-.85ft^3 net, tuned low to mid 30s, should be a great enclosure.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

WOOHOO!!

Fedex brought me a present today!!

I forget sometimes how small an 8" really is, and this thing is tiny. I think the motor structure really makes the woofer look smaller than it actually is. I cannot wait to get this box done to see what this little monster can really do.

I am planning on .8cuft tuned to 28hz, or as close as I can get with a mostly FG box.

Hope to have it finished within a week or so.
