For 2 years this well is entirely satisfactory ... HP's 300 Watt 15 "Eminence in its full capacity in a Ebenisterie idalie calculates ... punch, the bass, the sound is really clean, no vibration even full power in short nothing to do with cheaper products which are nevertheless of the same quips 15 "Eminence ... hsitation without counsel, the IDAL is to join him a 18" to get in HK the sub-bass.
