I recently aquired a pair of Altec Lansing Santiago's (878B) circa 1974 / 75 with the following components:

HF Drivers 806-8B
Horns 811B
LF Drivers 411-8A (Recently refoamed)
Xovers N801-8A
HF Attenuators 30904

Is it possible to increase the bass output and quicken the bass response by porting the cabinet?

If it is possible, where should the port be located (front or back) and what are the correct port dimensions?

What do you think the ported cabinet would sound like?

Could a JBL LF driver such as a 2231 or 2235 be used to replace the Altec 411-8A?

What would be the difference in sound between the Altec and JBL LF drivers?
