I have owned and listened to the 6 foot Magnepans every day since 1977.
The .7 series designed under Mark, son of the founder Jim Winey, simply does not go as low in the bass as the previous 3 series. That is my experience having heard the new .7 and .7i 6 footers in stores and in homes.
The .7 spec is a frequency range without any +/- dB listed.
The actual bass response is determined by the quality of the power amp, room setup and size of room.
The IIIa has the largest bass panel, and had a claimed spec of 32 to 40Kz +/- 4 dB.
I have heard all the 6 foot 3 series, and the IIIa goes noticeably lower than the others.
I have measured flat response down to 30 Hz with my IIIa, and 33 Hz with my 3.6 in various rooms.
I use the 3.6 in my living room and IIIa in my home theater currently.
