Modifying a vented enclosure to sealed.

Postby tomvh » Thu Apr 26, 2012 9:42 pm

I am building a Zaph 2.5 speaker with dual S.S. 8351's and a 6600 aircirc tweeter.
The Vented enclosure is 66 liter. The Spreadsheet I am using based on small signal Theil-Small equations suggests a 40 liter enclosure for a Qtc of .7.
I have the vented enclosures with a port tuning of 30 Hz. If I plug the ports air tight, my Qtc would approach .577 and my F3 would be around 55 Hz.

I would like some feedback or opinions on the best solution. The reason I am dong this is to have a 12 db roll off to match to a low Q sub-woofer.

Thanks in advance for your comments.
