Sorry for the late reply but i think 2- 10" type S gets its job done. It is kind of a tight bass rather than the rumbling bass of a Type R. Its a personal preference whether u like tight or rumbling bass but i love my type S. They mite sound wimpy because 2 subs are only 800 watts peak, but they rumble my neighborhood pretty sweetly. If u like tight, deep bass, i recommend them 100%. However, dont ever get just 1 type S. Always get 2.
