I'd like to use the 3Pi with my SE300B amplifier but I read several messages on the forum the Thermionic-series are more suitable for this task, however you send me the plans of the Theater-series. Can I just use the same material thickness but alter the dimensions of the box to the Thermionic dimensions ?

When using the Smith-horn on top of the cabinet, should I replace the woofer upwards or just leave it as is ?

Thanks,
Jim
