Hello Guys,

Needed your help in understanding whether speakers with rear port will suit my current set up. i feel due to irregularities in the backgrnd on both the speakers it's giving me a very boxy sound. do you think front firing port will help me overcome this problem and No, there is no one like prithvi over here who could lend me speakers to test the same.

Pls find below images of my room.

first, rear ported speakers should have space of atleast a foot or two. I dont think you have that. Secondly if you box your speakers in within wall mounted furniture, you are bound to get boxy sound. Speakers should be kept open and free.

Actually Irregularities and Wood actually do good to the sound ! they help dissipate/absorb rear wall reflections.

Of you can find the space you might like a pair of rear ported as well. I think Jamos can be placed close to the real wall for good effect.

Would suggest you do not worry too much about rear port/Front port. the manufacturer recomendation on distance from rear wall is good enough to go by

hey Benk, i'm not sure wht standmount means, if it means speakers meant to placed on stands then yes. i wud refer to these as bookshelfs (only refer, actual defination wud not be the same ).

hey neckie. yeah standmounts mean bookshelves.
anyway, for the kind of music u listen i think u need one which is dynamic rather than detailed. but detailing is a bonus if the speaker can reproduce joe striani or sepultura satisfactorily. but for that kind of music dynamic speakres with low end grunt is what is needed.
I don't want to make suggestions cause i have not really heard that many standmounts for enought ime to comment on.
The others are more knowledgeble on this.

Ben

Most of the speaker i auditoned had a minimum depth of 9 1/4" and the total space available to me is 10" now i donot have the option to leave even an inch for the rear port to breathe. now the problem is no one would give the speakers for testing, i would have to buy it and test it out myself, whcih is risk i do not wan to take. also i noticed that rear ported speakers gave a much detailed sound than the front ported ones...dazed and confused...guys....help!

Hmmmmm.....I dont know how do you justify that.

With the amount of space you have mentioned, I dont know why are you still thinking of a rear-ported speaker !!!! In my opinion you should concentrate on front ported ones and get something of your choice...

Rear ported better than front ported is no way a convention...

that is true Neckie.
rear ported speakers usually sound better cause the midrange is not muddled by the sound coming out from the port as it is away from the listener unlike a front ported design.

Hi Benks,

That would be too much of a generalisation, I guess.

I have come across some very detailed sounding front ported ones.

By this yardstick the best design would then have to be, after a sealed port, a side ported one and I dont think there are too many of them around...

i personally prefer a front ported design as i can push it closer to the wall ,something u cannot do with a rear ported one unless it was intented by the manufatureer.
there are many detailed front firing speakers. it is basically dependent on the design.

Hi Neckie,

Generally speaking, placing speakers on book shelves give you the lowest quality of sound. Placing them on sturdy wall mounted brackets would be a step upwards, whereas good rigid metal stands would make them perform at their best.

Your furniture unfortunately does not look like the best place to setup speakers. You do need around a foot of space between the wall and the speakers to let them breathe.

You could check out some Sat/Sub systems, maybe in your kind of environment, those would be the best option.

Good Luck!

Hi Neckie,
My advise to you again is not to worry about where the port is. The positioning of the speaker is more important that the port !

positioning nearness to a wall has more to do with the room interaction of the speaker than the port, the tuned freq of the port, the response curve of the speaker etc etc but on an average Most speakers, no matter where they are ported need to be kept at least a foot away from the wall.

eg a Harbeth 7ES2... a wonderful front ported speaker..but needs to be given a bit of a room to breathe.
the Ref 3a Dulcet/ a wonderful back ported speaker which needs to be kept only a foot away from the wall.

Hence just go by what you hear.. make sure that when you do a demo the speaker positioning is very similiar to what you plan to do at your place.

basically when u push a speaker to a wall u get an image of the speaker because of the sound that is reflected from the floor and this adds roughly 3db to the output.
likewise when u push it into a corner u get 3 images of the speaker when in reality there is only one actual image and hence u get arnd 6db gain.(like a horn effect)

Hey Neckie,
How about going by the 2nd option Big-Ears provided ?

I mean why dont you try rigid wall brackets !! That will save space on your bookshelves as well as make the speakers sound better.....

Wall brackets are not really very user friendly for Stereo... If you suddenly want to change the separation for soundstage adjustment, the task can be very painful !

Personally for me that itself is a reason not to go for it !


For an HT setup yes it makes things very easy..

neckie,

there are a few locally made stands available from hi-fi dealers. There are also branded ones from Jamo, dynaudio, lovan, cadence, wharfedale, etc. Buy ones that fit your budget, speaker size and probably room decor. Stands on tiptoes(spikes) are a must. Preferably ones which can be sand filled for resonance control.

Manek.
