the rca rt151 be good for amplify a quiet tv in a small child 's bedroom . if you have a modern hdtv , you will need a toslink adapter , currently sell on amazon for $ 30 , so figure you add that to the price , or not if you have analog audio output . the rca rt151 be just not good for a primary home theater , amplify in a room larger than 10 foot by 10 foot , etc. . truth be you just can not hear the dialogue that well , even on full power . you control the speaker with a remote control , and the only way you know its working be with a light that flash on the bass . have trouble hear the rear speaker even with my ear two foot away from they . you can isolate audio channel with the remote , with separate speaker volume control for rear , center , sub , and front , and finally master . pro : - good for make a quiet tv , in a small quiet room , sound louder Cons : - not for use in a normal size living room - require toslink adapter - Toslink adapter muff the speaker -lrb- I could have have a defective toslink adapter -rrb- - full power do not compete with most tv speaker -80 watt system do not seem accurate , my 14 watt tv speaker seem like the dialogue be louder . - rear speaker feel underpowered , very quiet , therefore the surround sound effect be lose . overall , I would not recommend this . if you have a small room , you should purchase other 2.1 speaker . if you be look for a entry level home theater system , this be not the one .
