I got my hands on 2 qsubs and a B2 today. I ran them underneath one Q7.
Interesting.
I'm going to post some shots off smaart 6; I hope they come through ok.
Measurement was EW M30 about 6 metres in front of the boxes, 1.5m in the air.
Source signal was pink noise out of the sound card of my notebook, and a cd.
From what I can tell, it looks like the B2 doesn't put out much energy above 80; whereas the Q subs seem to put out more above 125.
I'm trying to decide on purchasing between 4 q's and 2 b2's.
I'm not sure with pre-recorded music and pink noise which one I prefer. The Q's have more around 125, kinda gives it that "lots of bass" sound; but the b2's just deliver solidly on the bottom end. Kinda like there is a gap between the b2's and the tops.
yet, the spectragraph seems to show the B2 as a bit more smooth I think - yet with a dip at 125. Louder on either side. It looks like there is a shift to the right with the q7's - frequency response is allover, just a bit higher.
I've got 4 pics attached (i hope); first 2 are pink noise fed into the system as a whole (q7 and the subs); the second pair are just the subs playing the song "what kind of fool" at about 1:30 in; Streisand and Gibb. Where the bass and kick start in the song.
I'm not sure what i'm hoping to gain from posting this. Your thoughts but on what ?
Am I really asking... Do I want less 125 in my PA or not ?
Do I really need to try these out live ?
4 q's are more expensive than 2 b2's; the D12 will be the same either way; if I go the q's, i'd find a way to strap them together so that I move a pair as one.
2 q's take up less floor space.
there really isn't a lot between them.
Thoughts ?
I've got the speakers tomorrow so thought i'd post here and seek some opinions in the hope that in 10 hours time you may have some ideas for me to try.
I've got access to protools and some multitrack recordings; I may try a mix through that and see how it goes.
Thanks in advance,
Andrew
