I'm relatively new to the home audio market, but have dabbled in car audio for half a year or so. *bows for his first post* Anyway, I'm curious as to what the best sub for the money at/under $300 is for my current setup? My speakers are as follows: Front - 2x Sansui S-1117 (8-ohms imp., max 160W) Rear - 2x Linear Dynamics LD-3400 (4-6ohm imp., 110W RMS) If you need any more info about my system to answer, such as the main components, let me know. Also, would I benefit more from adding a sub, or upgrading my 4 speakers? They were handed down to me from a previous system and sound fine, but I am curious as to other possibilities... Thanks in advance for any suggestions - much appreciated.
