Speakers in the right enclosure will be loud and sound good, not a good way to describe what you want. We need better goals than that to help you out. i like low clean bass i was thinking the the ssd cone area would acheive thjis better am i right about this? Cone area usually plays a role in louder than low clean bass (that will be achieved with the sub in the right enclosure tuned to your listening preferences). The only way to really tell is to buy both sets off subs and test them yourself, but if it were me I would go with the FI SSD's. I did hear the Audioque's do get loud though. see i have the hdc3 in a center console box but they not getting as low as i thought idk if its my box are what i also have an ssd 12 that i use to have in a single sub setup and i loved it thing is to sell the hdc3s they are brand new.
