Rear fill?

Okay, I have a question about the necessity of rear fill. I was talking to the guy that does all of my install work the other day and he was telling me I should really think about putting some speakers in the back for rear fill. I have always believed rear fill to be unnecessary, especially in my little Honda Civic Si, and it seems like most of the knowledgeable people on this forum would consent. However, he said that most of the music recorded is designed for full range sound and I'm probably missing some material in the music by not having rear fill. He also said it would simply sound a little better having rear speakers, kind of like a surround effect for home audio. He suggested just getting some midranges and playing with just enough volume to help fill in the sound, nothing too loud though that would distract from the front stage. What do you guys think?

I'm not the most knowledgable person on here by far but that is also what I intend to do. I personally like the way it sounds having a little more fuller midrange/midbass in my setup. Also about those Infinities just let me know when you are ready to sell and we'll talk more about it. Also you said they are in perfect shape so I am assuming that you have all the original packaging and stuff?

i cant stand my tunes without some rear fill. it sounds average without it. the rears give it a fuller sound. i like the music to sound like its coming from inside my head. like im "ON" the stage with the band, not looking up at them like frontstaging will do. the music should surround you. its much more immersive and true sounding like that. frontstaging sounds not so realistic and weaker but its all just my preferences. well tuned frontstage systems sound awesome, just not as awesome as rearfill systems IMHO.

Hey Aaron, yeah I should have all the original packaging for the Perfects. Believe me, they have not seen much use and are probably just now reaching the end of their break in period. You would be very pleased with them. I'll be sure to let you know when I'm ready to ship them out after getting my other set, which hopefully will be within a week or so. Thanks again.

with a proper front stage and subs, you'll have full range. no need for rear speakers.

"He also said it would simply sound a little better having rear speakers, kind of like a surround effect for home audio."

in a home theater, you have 6 discrete channels, so rear effects or surround are a separate signal. surround is also strictly midrage, ambient effects like crowd noise, traffic, etc. no need or want for this effect in music which is ideally stereo 2.0

"He suggested just getting some midranges and playing with just enough volume to help fill in the sound, nothing too loud though that would distract from the front stage. What do you guys think?"

read this. print this and give it to your man. see what he says.

Hi Glass, in some paragraphs you mentioned rearfill frequency range 200Hz to 3KHz, and in some places it is 300Hz to 2KHz. Any correction?

It even has graphs that show the phase anamolies that rear fill causes in a car.

within half an octave either way on both specs. it's personal preference.
heck, you can go 150Hz-5000Hz if ya want.
I just like to keep it in the range of 200-3000Hz
it's not going to be an exact frequency anyway with tolerance differences of the capacitors and coils, and the fact that they won't come out to exact numbers anyway. just get it close and you're fine.
