hi guys am planning to add a centre channel to my setup soon (currently using a phantom centre)consisting of diamond 8.2 fronts. i was just thinkthing that instead of buying the dedicated diamond CC spkr why not buy a pair of 8.1 bookshelves which wld cost abt rs.500-1000 more. which wld mean for the same price i wld get an extra spkr (which i cld use as the surround back). are there any disadvantages to this, u think? also since i hv an rptv i will be mounting the CC spkr (whichever i decide) on the wall behind the tv; so size is not that big an issue. appreciate your input. |

Hi Filmguy, I definitely think, there would be a disadvantage as you are not using a dedicated CC. Going by your name it seems you are a movie freak ![]() |

hi abhi.pani actually i got this idea when i read somewhere that infact the dedicated CC spkrs which are usually 2 drivers placed horizontally are not acoustically the best and infact it wld be better to use the same spkr that one used for the fronts; so if u hv towers then its better to use towers and so on.. but i'm not 100% sure of this thats why i'm looking to u guys for feedback.... |

You can try it out. ![]() If you are not satisfied you can use the pair for rears and then buy a diamond 8 centre. ![]() Just curious what AVR are you using to drive your 8.2s? |

hi... Alymangy - i am using a marantz sr-4300 AVR..ur idea of giving it a try is sound but unfortunately i dont hv that kind of a budget. i am quite ok with my sony hifi spkrs that are doing duty as surrounds right now..i'll probably look at upgrading those later this yr but for now its the centre (and sub) that i'm looking at. manek, arj, others, any thoughts on using bookshelves as centre.. |

Ive never come across book shelves used as cenres and I feel centres are more biased towards mids - the dialogues of movie..so I don't think a book shelf can give you the same performance as a dedicated centre channel....... |

i think it can be done. but you'll need to connect them properly so that the impedance is right as u will be connecting both to the same channel. audition them and see. it may end up sounding better than the dedicated center. the important thing to consider is the crossovers. the crossovers will definitely be different between the bookshelves and the center. as in dts or dolby specific frequencies will be given out in specific channels. so you may end up losing some of the freqs. if i had the cash i would probalby look fo rsuch a solution. frankly speaking, iown the diamond8 center and have'nt looked back since the day i bought it. i just finished watching the Lord of the rings-two towers and wow that center channel really is a cornerstone of my system. there are absolutely no distortions and this is in default mode. i am now fiddling with the equilizer settings and speaker setup. happy listening. |

Hi filmguy, Centre speakers, with their MTM design, may not be the best possible way of delivering the widest dispersion horizontally, when placed on their sides. Then again, a dedicated centre, with two mid range drivers and a tweeter, would be optimized for vocals, unlike a book-shelf. It is a trade-off basically, with good manufacturers doing their best, to let us have the best. Your suggested location, behind your RPTV and on the wall, would also need looking into, as the RPTV would be larger than a normal TV. Ideally, the centre should be placed close to the screen, reason being, voices should seem to be coming from the lips as you see them moving on screen, especially during close-ups, and not somewhere else. Try experimenting with your Sony speakers as the centre, in the location you are thinking of, to see how well (or badly) they perform there. But as I have said, you will need to ensure wall mounting does not in any way compromise the dialogue delivery, especially in close-ups. I am also somewhat confused by the mathematics. Where would you place the remaining bookshelf? Is that a 6.1 channel receiver you have? |

hi big ears yes if i go this route i will use the other spkr as the surround back (the "6"th.1"). unfortunately other than the exactly on top of and on the wall behind the RPTV are the only 2 options that i hv for placement. and on top i am avoiding bcoz its quite thin (5 inches) so i dont want to place a spkr there and hv it fall of by accident.. the whole reason i came up with the idea of using a bookshelf as the centre was i read an article on one of the audiophile sites where the writer said that in fact the horizontal CC's were bad for the harmonics and they were made like that only for the convenience factor and the best situation wld be to hv the front 3 spkrs of the same type. i wld try the sonys but they arent of the highest quality and so they wldnt give me a true picture... |

Hi Filmguy, A peculiarity of speakers with a vertical MTM driver array is that they offer the widest dispersion area in a horizontal plane. A horizontally placed CC, of normal MTM design would, on the basis of this logic offer wider dispersion in the vertical plane. Now, if yours is a typical living room with 3-4 people seated abreast watching a movie, a good CC would do the job well enough. If however, you have 10 people sitting abreast in front of the TV, then those sitting at the ends would obviously not be able to get the best out of the CC. Sure, three identical fronts would be a great option to have, but if your L and R are towers, then the Centre would also be a tower, and in a normal living room how would it end up being placed? You would need a dedicated HT room. There you would have a gamut of options. As said earlier, the normal CC is a compromise addressing most of the problems. Higher end CCs have offset tweeters, or even 4 and 5 drivers, to offer better harmonics and dispersion. But then, they don’t come cheap. You are right about the Sonys not giving you the right picture. Not being timbre matched, they obviously wouldn’t. But at least you would know if the location was okay. For eg, if in a close-up it sounded as if the voice was coming from over the shoulders and not the lips, then you would know for sure it wasn’t the best position for the CC. You could also keep the CC in an area close to the TV throughout the day, for the sake of safety. Then, when you watch a movie, just plunk it over the top… |
