A speaker secret possibly used on Amazon Alexa too

At your risk. A very helpful tip on building or making loudspeakers is that the box be much larger than the drive unit, or vice versa that the drive unit be much smallermuch than the box. This can give excellent no boomy and deep bass if the drive unit has a low reasonant frequency. For a closed box this reasonant frequency needs to be much lower than needed since when when the drive unit is mounted in the box the frequency will be raised by acoustic suspension. Anyway a 4.5in Fostex FE127E gives amazing bass on a bigger Pioneer box (see previous posts). And this Christmass present from my brother and his wife to our parents is an Alaxa, Amazon. Inside it is a tiny speaker. But the bass is surprisingly deep for Alexa's size. Do they also EQ?
