Frequently answered questions
Is it possible to use three Q-SUBs in CSA mode with Q1s in a ground stack?
Yes, three Q-SUBs on a riser with the centre cabinet reversed for CSA performs very well. Though musicians may at first be concerned by the lack of bass energy on the stage. Please refer to TI 330 available at the Documentation/White papers/Technical information section of this website.
What happens to the low frequency distribution when all the Q-SUBs are flown?
Q1s with CUT selected still produce some energy down to 80 Hz. When the total vertical length of the array is large the vertical dispersion will be reduced drastically. With the pick up point at a 10 m height you will find as you approach the array from the front that you will start to loose bass energy from approximately 20 m in front of the loudspeakers. The low frequency energy right underneath the column will be considerably reduced. This might be perfect for a corporate event, but for live music performances there might not be enough low frequency energy in the areas close to stage.
Can you use the Q-SUB with the B2-SUB?
Yes, the B2-INFRA mode allow both subwoofers to work together.
Does Q-CalcRig and Stack include all Q-Series loudspeakers?
No, the spreadsheets contain the Q1, Q-SUB and enables a single Q7 to be used as a downfill in the Q-CalcRig version, however the Q10 loudspeaker is not included in either. These calculation tools are available in the Support/Downloads/Array calculators section of this website.
Can you rig a column of Q-SUBs so that there is a similar curve as the column of Q1s?
No, this is not possible. Q-SUBs can only be mounted without additional splay angles.
Can the Q Flying frame be used upside down to support a ground stack?
Yes, with the Q-SUBs placed on top of the frame it can be used to build a ground stack, for example of three Q-SUBs and two Q1s.
Are there Macintosh versions of the Q calculators?
Yes, the Q-CalcRig and Q-CalcStack calculators can both be run on Mac and Windows platforms.
What is the difference between the Qi loudspeakers and the standard Q loudspeakers?
Acoustically there is no difference at all. They only differ in cabinet hardware and front grill.
Can J-SUB be combined with a Q-SUB / CSA arrays
Basically yes. J-SUB in principal is designed as 3 xQ-SUB / CSA but all in one box, more compact, can fly, less weight, tuned somewhat lower in frequency and, last but not least, therefore cheaper. Of course approbiate spacing between arrays have to be obeyed.
Can a B2/Q-SUB/J-SUB/J-INFRA be used in conjunction with the B4 subwoofer, and can a B2 be placed next to a J-SUB?
We do not recommend mixing omni directional and cardioid subwoofers.
How far off the wall can it be positioned?
It can be placed the wheel distance from a wall as this does not adversely affect the performance at the front. The main thing possibly influenced is the cardioid performance which happens behind and to the back sides of the speaker. This is valid for the B4-SUB, J-SUB, J-INFRA and CSA setups.
