Hi, what do you do not get anything for your cinema feeling in your own four walls. In addition to the purchase of a regular TV and BluRay player, the acquisition of a befitting audio system is mandatory. I recently purchased a Pioneer AV receiver KSX 521-K and wanted to connect it to my existing Magnat 5.1 speaker system. The speaker verichten since 12 (!!) years their service reliably and should remain. After the receiver was connected was the disillusionment ... the subwoofer could no longer be addressed. Therefore I SW 40 ordered me to Kenwood, with just under 80 euros a rather low price device. Yesterday I calibrated and connected everything. One would expect from such a subwoofer not magic, but the sonorige sound and punchy bass is a real asset to my system. The subwoofer has moreover a rated output of 85Watt ... the 100Watt would also provide the subwoofer only very briefly and only once. My living room is about 20 square meters and space for this size of Kenwood Sub is more than aureichend. The subwoofer will add just a rich "base" in the sound of the home theater system with BluRay playback effects are powerful and very present, XBox360 Games are well staged. The bass pressure is certainly not a "punch in the stomach"; Reviews also "to bring the sound pressure to bursting window" that speak of it I think is questionable. But if, like me, from the "the subwoofer must annoy the neighbors" -age is out and a suitable accompaniment for coordinated audio experience studied, one can confidently pick up the Kenwood SW-40; for the price you get a very decent product that is very neat processed and high quality. A star deduction is available for the available ports ... single RCA input: the wars.
