Mark did not review the turbocharger. He mentioned port noise tendencies only in the extended bass mode with port plug, which is exactly the situation we were trying to move away from with turbocharger. Port noise is definitely not an issue with the turbocharger.
Sure one could design a larger enclosure, but even that would see a performance benefit from using turbocharger instead of plugging a port to reduce port tuning. The idea was definitely to make the unit install in a modular fashion.
That makes sense.

It is a great product and innovative design, no doubt though. Why not make a new sub that is a bit bigger (enclosure to house everything) with longer, straighter ports? Problem solved. I can see it as a great add on to existing sub systems though.
