Well this is in my bedroom but I like to be able to feel my music which the EP175 really didnt satisfy me but it was fine for movies. I didnt understand what sirquack meant about setting the DBs I dont think my A/V even has that setting or it has it called something else. It does have what it calls "channel level" which is in DBs but my manual says in general to leave the LFE level to be adjusted to 0dB (however the recommended LFE level for some early DTS software is -10dB) I dont really get that yet I still am a rookie. It does have auto calibrate with the microphone which I tried and I didnt like how it sounded when it was done so I did not use those settings. Now back to the channel level which I have at 0dBs on all the speakers according to sirquack I should put it at 75dbs Is that right??
