rear channel speaker question

Hey guys. I'm looking to upgrade my stereo system with a new receiver
(Denon AVR-1603) and centre channel (haven't decided on which one, but
perhaps a Paradigm CC-70). I'm already happy with my two fronts,
which are Paradigm Titans (v3). What I'm mostly uncertain about is
whether I should upgade my rears or not. Right now I have what I dub
"poor man rears", or in other words, they are speakers from an old
1998 hi-fi system. To be exact, they are Panasonic SB-AK45 speakers
with the following specs. They sound "adequate" but I really can't
decide if it'd be worth it for me to spend a couple hundred more to
replace them
Type: 4-way speaker system
Speakers
Super woofer: 17 cm cone type
Woofer: 12 cm cone type
Midrange: 6 cm cone type
Tweeter: Plezo type
Impedance: Total 6 ohms
Input power: Total 160 W (Music), Total 80 W (DIN)
Output sound pressure level: 84 dB/W (1.0 m)
Cross over frequency: 200 Hz, 3.5 kHz
Frequence range: 45 Hz - 22 kHz (-16 dB), 55 Hz - 20 kHz (-10 dB)
I guess my major dilema is that I have a major interest in audio
quality, and can really tell high end from low end. But of course,
I'm on a budget sicne I'm a university student, so anything that I
many not need right now I probably shouldn't spend on. Anyway I'm
hoping some of you might be able to tell me your honest opinion of
these specs as my current rears. Thanks!
Which Surround spec are you most concerned with hearing? You need GOOD full
bandwidth real channels AND center channels for true Dolby Digital. I think
DTS is bandwidth limited in the rear surrounds and center channel.
Short answer, if you want to hear true Dolby Digital Surround, you need full
frequency Center and Rear Surround speakers. If you only want to hear DTS
properly then don't worry about the upgrade.
Ideally you want an identical speaker for each channel. (Ie. One CC-70 for
each of the 5 channels, and then an LFE speaker)
If you can't do that, make sure all your 5 surrounds can handle real full
range input. (50Hz - 16Khz is usually the effective minimum bandwidth)
