Hello, I recently purchased a Dayton Audio Titanic MK3 15" I would like to build my own enclosure for it, there is an enclosure design listed on the site for the i bought subwoofer though it is not the manufacture website. I am not very expirenced in building enclosures but I thought the enclosure looked pretty good. Though I have one issue, if you looked at the specs, you will see that the sub box should have a 6" wide port that is suppost to be about 33' long, though the box will only allow about a 22" port. It is noted on the site that port will have to be "angled", I can only assume this means that there will have to be an elbow the redirect the port in ordeto make it 33" long. I also am having trouble finding a 6" diameter PVC pipe and i would also want flaired ports buit I cannot find a good one. So I was woundering if running two 3" ports would effect my tuned port frequency drastically. If the effects will be very different from the original design, how do I correct that for use with two ports, also the box size given by the recommened enclosure is slightly smaller than the recommened size of the subwoofers specifications. I heard that stuffing an enclosure with foam would give the effect of a larger enclosure, would anyone recommend this? Lets say that I used two 3" instead of one 6" port, how much shorter would the port have to be in lenght? I am aware that people are going to want to know my listening habbits, I will use the sub for about 70% music and 30% movies. I do enjoy listening to rap at high volume levels and i would like the sub to hit at least 25hz, prefrebly around 20hz.I will be using the sub with a set of Paradigm Monitor 7s and was thinking of using a Denon AVR-1505, would anyone recommend another reciver for the Paradigms?
