Even thought i didnt say it to him I prefer my panasonic for sound as it the spread of sound is even across the front 3 speakers. the SUB is excellent and I dont notice it drown dialog or distorting. but then on a good movie the sitting room door it rattleing away! lol  Not to mention mines cost 5 times less 6 years ago. Also on Max volume I get little to none distortion, I just have to turn it down because it is get sore on the ears! lol
If I was going to buy a denon/onkyo AVR I would need to use my current speaker and save up a bit for a new decent speaker package.
My only concern is would I have the possibility of damage to either the AVR or the speakers as they may not be matched to each other.
SimonsPlasma , that is the correct number on the subwoofer but it is not a stand alone subwoofer. the only input to the system is via the dvd player. there is a control cable from the dvd player to the sub, where the amp is built in for the surround speakers and the sub itself. can I use the panasonic for just the sub? ie, remove the surround speakers, and run a cable from the preout on the AVR to the panasonic system? |
Bose are rubbish mate!! Over priced all in one tat. If the speakers were 6 ohm all the way across then I'd be happier I'm slightly concerned though that its a mixture of 6ohm and 4ohm with the majority being 4 ohm. Depending upon the AVR you buy that might lead to it running quite hot as it'll be working harder to drive the 4 ohm speakers. Most easier to drive 'real' speakers sit at a nominal 8 ohms. The real monsters will be between 2 and 4ish ohms. Someone needs to have a look at the manual to see if the sub can be driven seperately I'd suspect not though as for an all in one system that would be rather against the point.
Is it an SC-HT870? Ie one of these
http://www.avland.co.uk/panasonic/scht870/scht870.htm
Front 170W x 2 (1kHz, 4ohms 10%THD)
Centre 260W (1kHz, 4ohms 10%THD)
Surround 70W x 2 (1kHz, 4ohms 10%THD)
Subwoofer 260W (100Hz, 4ohms 10%THD)
Total Power 750W
Those figures are'nt actually all that great the give away is that the measurement is at 1KHz not across 20hz to 20KHz and even then the THD is 10% (Total Harmonic Distortion). This implies they are all 4ohms so at least they would be the same load. Definately check that amp you purchase is happy with 4 ohm speakers. This is a standard ploy used by all in one systems to bump up the powah. By using low impedance speakers the amp has to work that much harder hence it uses up more power. The problem is the THD figure that should be 0.x something or better yet 0.0x across the full frequency spectrum that the AVR will be producing the fact that its struggling at 1Khz isn't great. However this is all down to the amp in your system not the speakers. I'd give it a go and possibly be a little careful with the loud pedal on your new amp. As there is no real information on the speakers sensitivity or the frequency range they actually work at.
