Hi,
Here is my first attempt to build a pair of speakers using Philips(Boston) driver - HQ48414 / 25W / 93dB. It also has a tweeter from Alpine

I need some help from experts. While I am happy with the rich mids and sweet highs the speaker produces, wondering if anything can be done to improve the low end response.
Can I convert this from a sealed enclosure to a front ported box to improve the low freq response. If so what should be the dia and length of the tube ?
Inside dimension of the box in cm is 21.5B/33D/38H. So I guess volume will be roughly 27L including space occupied by the driver. This was the biggest box I could build with the half sheet of ply I had
hyeah:
By the way , initial testing was done with no sound proofing inside. My reference is an MA BR2 speaker![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
