NHT Evolution W2 Subwoofer System comprising of:
4 only 12″ Subwoofers
2 only A1 NHT Amplifiers
1 only NHT X1 Electronic Crossover
I have used this system in my own home theatre for the past 7 years and it is now time to move on.
Obviously this is a large system, and will suit medium to large rooms.
