The home theater system BRX-610 from Yamaha provides eien very "thin" Bass. To fix this, I have the subwoofer Pioneer at Amazon purchases (low price, a lot of good reviews). The speaker was fast and packaged very well supplied by TSN. Then there were only problems. The subwoofer is a cinch cable to the subwoofer output of the BRX-610angeschlossen. Also for the optimum configuration of the BRX-610, the bass performance was no better than a "normal" connected subwoofer. Here, the volume control on the subwoofer was on maximum volume! In addition, the subwoofer had every newly made / are turned when the was BRX-610 eye on! It did not matter if the standby function was on or switched off. The BRX-610 has been switched on again there was no bass! To this was then a very unpleasant smell of "electronic", when the subwoofer has been operated for more than 1 hour. Very disturbing is the aussergewöhlich light power indicator of the subwoofer. But that would not bother me, because one could somehow, cover the display. Ultimately, there were demands for at TSN and even with Yamaha not solve the problem, so unfortunately I have returned the subwoofer. Again, the settlement by TSN was exemplary.
