Mixing up?

make sure the big floorstanders are av recvr friendly and have a impedance of around 8 ohms....you should be fine.


You may end up with better sound...if thats what you are asking.....and just may end up not buying a sub.
manek.

yup it's 8 ohms and the floor standers have 8inch LFD , 4 inch MFD, 1 inch HFD plus bass relex and in addition i add a sub( can't help it ,it's in the HT package). but the receiver claims 100wpc and the speakers are 40wpc..any suggestions

yo sub,
what's happening. give us some details on the speakers and the receiver.
many companies claim a high rms rating but end up producing barely half that(yamaha is one of them....their low end recievers atleast) except for a few notable exceptions like Harman kardon,rotel...

hi benke

any receiver you can assume with 100wpc rating in the YAMAHA or ONKYO category.The question is interested in the answer being specific to tech stuff or other variations generally occur and not comparision of brands.so any pearls of wisdom from your side

well, from what i have heard and seen,the best example would be bose ht system.
i mean the soundstage may be great but it just lacks the depth. you may say wow at the first time you hear it but beleive me it really tires my ears after listening for 10 minutes. you feel like switching it off. besides the bass extension you get from larger drivers is unquestoinable (mind you, generally as the drivers get larger, the sound quality tends to suffer. eg- its better to go for a 10" than a 12" if you are looking for SQ. but if it depth that you want increase the driver size and you can go to really low frequencies). the smaller speakers are more concerned with producing a surround environment.
but let me not stereotype it. there are some very good subsat systems that perform well both in stereo and HT mode. personally, i think the best speaker to have for stereo would be a 3way with 12" LFD, 6.5" MFD(a dynaudio or audax driver) and a titanium(jbl) or silk dome tweeter.

let me add that the speakers need to be efficient, atleast 89Db. if you have noticed in one of my posts i have said that my receiver is probably the only weak link. i say this because my 8.4s and diamond8 center are all pretty inefficient and gooble up power. my yamaha 450 runs out of steam and i get scared turning it up real high as i am afraid the receiver may start clipping. i generaly turn up the volume 60 to 75%. beleive me this is high. but it has always made me want more. its very important as Manek points out to have a capable amplifier with true RMS power or have a pair of very efficint speakers(>=91Db).
cause when they say 510 watts Rms(All five channels driven) you will be lucky if you get 60% of that when all the channels are driven. another thumb rule is that the heavier the amp the better(higher va transformer, higher capacity capacitors, better heatsinks, construcion,etc). when it comes to audio power is very important but so is the way it is delievered( read 'SQ').

IMHO, you would end up sorrier, because the tiny centre of your speaker package would not match the large floor-standers. If the floor-standers are sensitive and the receiver powerful enough, you may find the dialogue getting overwhelmed by the sound effects emanating from the fronts. Or, say, you have a scene in a movie where there is a lion striding left to right across the screen, roaring. You don’t want to be in a position where it begins as a roar, turns into a mew or a squeak when the sound pans to the centre speaker, and changes to a roar again.

Okay, that may be a little exaggerated :D, but in HT, to get seamless sound, one should ideally have matching fronts and centre. The rears would not be that critical.

Also, if you are looking for good HT sound, the way it was intended to be heard and felt by the movie director, I feel you cannot really wish away a sub. A decent mid priced sub would go down to around 22hz, whereas the floor-standers would go down to 45-50hz – you would be losing all the LF information that the director and sound engineer have so painstakingly fed in for you...

Hi big ears,

man iam not gonna junk the sub and i shall be using it. I thought so I can add up floor standers instead of the tiny matchboxes.....or rather call it fronts will enhance the bass response(65hz to 250hz) and not low bass as the sub will take care of it.

There is something wrong there.
Wharfedale Diamonds are actually pretty "efficient" (I presume you mean sensitivity..efficiency is an altogther different Ball game !) and even a 30 W amp can drive them to ear breaking levels in a standard minimalistically damped 12 X 14 room.

benkenobi, is your receiver power rated at 8ohms or 4ohms ?(Onkyo gives x 6) hence the power into 8 is much lesser !


I run bose speakers (rated at around 86 db) with a 65W onkyo receiver and have no problem reaching ear blasting levels in a 500 Sq ft hall !

Agree with Big ears..floorstanders do sound much better on an HT, but usually is is size& Placement Vs Performance decisions which caus problems

whatever big ear said about the centre channel is true...get a good solid centre and preferably timbre matched with the fronts....very important.

Hi Sub Boss,

Of course, with your moniker, I guess you would be the last to trash the sub .

To share with you my experience, I began my HT tryst some 9 years back with a Bose Acoustimass system which had 3 identical cube speakers for the left, centre and right, and a passive bass module. The rears, I made up with Bose 201s. The receiver I think was a Yamaha, with 75W x 3 for the front plus 35W x 2 for the rears. Subsequently I went in for a pair of transmission line floor standers which were absolute bass meisters for the money. They were wonderful for audio, and certainly enhanced the sound and the bass for HT, but they also brought with them a very irritating feature. The action effects kept swamping the dialogue. I had to sit throughout the movies with the remote in my hand constantly increasing the volume whenever there was dialogue, and reducing it hurriedly whenever there were action scenes, lest my neighbours came a calling. This mismatch was most frustrating, to say the least. I got rid of the Bose system and bought myself a solid dedicated Infinity Centre which matched well with the floor-standers and life was pleasant once again.

With that lesson in mind, throughout my subsequent upgrades I have ensured that I do not compromise on the centre speaker. For movies, the dialogue is the most important part, if you cannot hear clearly what the characters are saying to each other, you really do not understand what is happening on-screen and I am afraid you are losing the essence of the movie.

What speaker package are you using?

what's timbre matched fromts and centre
