All depends if:
1: You're a relaxed track day kind of guy.
2: A competing MSA touring car racer.
3: 2nd or 3rd off grid in Formula 1.
If you are relaxed track day guy then no problems at all using G Subs with mini scoops, full scoops or even bullets with no crossovers playing bass. Just sit back, plug it all in and relax to some great music with your favorite bevy.
If you're a competing MSA touring car racer then you have some competition and should have a greater knowledge of your sport. Reflex with a mini scoop is doable in the same band, but you better know how to measure an impulse response and transfer the results to useful time and phase settings to get the best from your setup.
If you are competing in F1, then you won't even be trying to make two competing pieces of equipment work together. You simply go out and use the best equipment with the highest specs for the job, as you have the budget and years of knowledge of how best to use the massive funds you have available.
Do note that options 2 and 3, even though the initial setup costs are higher will pay for themselves, both financially and rewardingly. Option 1 is easy, sexy and brings frustration as you realise you were much more than you previously thought.
