Cool

since they are dd knock-offs they can probably take a little under what is put on the dd9500s. probably could take 6000 burp depending on the note. you could do more power with a higher note

soundqubed is just built dab cheaper but are still god subs thats why you can use dd for comparison. not trying to dis the company or anything. the soft parts arent the strongest so be careful when burping unless you have recones on deck

oh almsot forgot but for daily it depends on your setup. certain enclosures allow you to dump more power but running more than the rms on those subs isnt recommended. my friend with 8 15 (hdc3s) runs a little over 10k and does 159s in a 6th order. so just give those subs about 2500 daily should be fine
