...what do you think would sound better...
To me, the key words there are "what do you think", in that what I "think" (or what anyone else may "think") sounds "better" is often a highly individual choice, …a matter of personal taste.
However, I also feel that over forty years of designing, building, operating and touring audio equipment for a huge variety of purposes may mean that I can at least offer a credible "real world" opinion, albeit one that you should feel free to either consider or disregard.
My feeling is that, regardless of the style involved, the propagation (or "spread") of bass is absolutely critical for dance applications, because that bass region is where most of the rhythm "lives" …and not only is that rhythm information fundamentally vital for the basic coordination of tempo, but also it's the "heartbeat like" kick drum frequencies that are often the primary motivators of the actual urge to get up and dance.
Couple those observations with the facts that
- The bass region is also the first to suffer when speakers are outdoors, lacking an enclosed volume in which to operate and
- Subwoofer "energy" (when compared with that from the mid/tops) is the major contributor to any overall impression of "loudness"
…and you can see where I'm headed.
You guessed it.
For any dance application, I honestly reckon that any (possibly) "extra" cash is far better spent on a pair of (or more) "subs", rather than first allocating it to bulkier and (hence) harder to elevate mid-tops.
Given that "outdoor" generally also implies "temporary" and/or "touring", having subs not only for "bass", but also as "bases" (for the convenient elevation of pole mounted mid/tops) is a great way to speed the rig and de-rig process, while simultaneously eliminating any need for the separate (and hence more bulky) tripod stands that would otherwise be required to distribute music over a field of gyrating bodies.
