Qtc of 0.889 for sub?

[KEW]

My understanding is this is not a highly damped system. What exactly does this mean from a sound quality standpoint?
I have two TC Sounds RL-S12 drivers, (which I understand to be a re-badged "TC Sounds LMS ultra" per Chris/WmAx).

TLSGuy calculated the parameters in a 2.0 Cu.Ft. box as :

Name: RL-s12
Type: Standard one-way driver
Company: Soundsplinter
No. of Drivers = 1
Fs = 30.97 Hz
Qms = 7.459
Vas = 27.65 liters
Cms = 0.0767 mm/N
Mms = 344.2 g
Rms = 9.097 kg/s
Xmax = 38.5 mm
Xmech = 57.75 mm
P-Dia = 254.1 mm
Sd = 507 sq.cm
P-Vd = 1.952 liters
Qes = 1.114
Re = 2.88 ohms
Le = 2.54 mH
Z = 3 ohms
BL = 13.5 Tm
Pe = 2000 watts
Qts = 0.97
no = 0.0711 %
1-W SPL = 80.66 dB
2.83-V SPL = 80.5 dB

I kind of aborted this project because I assumed higher damping is very important for SQ and I was thinking this was more of a boom-boom car sub driver. Was that a good call or a mistake?

Thanks!

.707 is often he goal, but +/- a bit isn't necessarily a deal-breaker- it depends on room size, required frequency response smoothness, source material, etc.

Using slightly higher Qts can help a speaker provide more impact in certain environments. You wouldn't have problems with 'ringing' until you approach Qts of 1.1 or more and that's why this is used in audio systems for Rap & Hip Hop. They're sometimes called 'One note wonder' systems because that's about all they do well- one note.
