Notes

The PSI 18 recone of an Elemental Designs 13AV2 motor wants a somewhat larger enclosure than the 4.2 cubic feet available in the 18 sealed test enclosure so the response ends up rather peaked but it would only be marginally flattened even in an IB and most end users or engineers want to utilize smaller enclosures for many reasons anyway. It does not appear that there are inductance combating measures in the 13AV2 motor or if there are, that they are not as effective as they could be. Also for whatever reason this driver has a rather high deep bass distortion despite a generous amount of stroke being available. It has plenty of output headroom available across the 10-100Hz bandwidth it just has some extra distortion below 20Hz. This is not a standard driver sold or designed as a complete unit so it could have any number of causes. Still a few of these employed in a vehicle or home theater would be plenty capable of prodigious sub bass with a little bit of signal shaping involved. It would be best to cross this system over at or below 100Hz due to the top end roll off.
