Is room size considered when they design speakers?


Never see speakers saying best used in a 15 x 15 room.   
Also, why do speaker cabinets tend to be larger as they get more expensive? Not easy to answer. I know bigger handles bigger drivers but is this the only reason?

I too have long wondered why manufacturers don't limit their sales by telling customers they only really work in certain limited situations. Also why would they charge more just because they need to use more material to make the product? Fascinating questions. Can't wait to hear if anyone is able to come up with the answer.
Like selling a +200hp car for 130km/hr speed limit? 
Many mini monitors are too expensive and many towers with multiple drivers are too economical.
Also some manufacturers claim use for their products in limited or larger space.

Maybe you could consider asking the specific manufacturer or respective dealer  the question. When I was looking to purchase Daedalus Audio speakers one of the things I discussed with Lou was my room size/layout and he went through which models would be better suited to my room. Likewise, when I purchased JM Reynaud speakers Bob at Amherest Audio and I also had that conversation going through JMR’s lineup.
Great questions!  I too can’t figure out if big speakers work better in big rooms or small ones.  Manufacturers of speakers give no guidance as to what speaker works best where.

2 companies that come to mind are OHM and Canton, both give guidance as to what speaker works best in what space.

And another great question is why does a 7 series BMW cost more than a 3 series?


Ohm speakers do exactly that. Website lists the proper size for a particular size room. Larger room needs larger speakers. Larger speakers cost more. Very simple and easy to choose.  The design scales up and all sizes deliver the same sound set up properly.    Nobody else does this that I know of.  Makes it easy to pick the right speaker for your room. 

As originally intended the buyer would sit cross legged in the room, not even need to connect the speakers, merely chant the name Ohmmmmmm ohmmmmm ohmmmm ohmmmmm ohmmmmmm over and over again, after several hours inducing a trance state in which transcendental audio performance is imagined. Then someone pointed out the many insurmountable problems with the speaker itself. But being a small company they could only afford to tackle one, and so the name was shortened to just Ohm.

Who about what? millercarbon always about Tekton.
BIG speakers that move a lot of air, work better for me in a ported ROOM...Large Baffle speakers that DON’T move a lot of air but have a wide baffle add a LOT of early bass reflections BACK to the sweet spot. The smaller the room and the larger the speaker, the more I open the room up. I open two rear 36" french doors. It "ports" a lot of the extra bass and depressurizes the room plus tames the low mids. Those waves are still pretty long. they go right on out the doors behind the seated position..Along with Xtra bass ect.. works quite well

Look at the speakers I use the forward facing baffle is only 6-8" wide and the speaker is over 390 lb and 74" tall The rear baffle is 16"

The smaller version for smaller rooms is close in width but only has a 8" rear baffle and 48" tall. Either works just fine, there is a larger and smaller version too. Understand, these planars alone will handle 300 watt on the small ones and 500 on the Elixirs, They will leave you DEAF and calling 911.
Add the bass 300hz and below which (NOW) is comprised of columns (of course) 4 12" MB and 4 12" subs. THEY move the air.. the planars don’t.

You stand in front of those planars and turn um up, YOU’LL catch on fire. LOL. You stand in front of the MB columns, LOL it will push the air out of your chest... The subs, do what subs do... NOT MUCH...
Put on 50 cent.. hee hee.. Tape the windows on the french doors they will back the screws out of the sheetrock.. YUP.. No nails in that room..

With OB servo bass you can close the doors. weird.. Completely different how the room pressurises.

SIZE counts... I guess..

millercarbon, have you ever considered useful responses?


I have, and have come to the conclusion the most useful response isn’t always the one that takes the question the most seriously. And here’s one for you: have you noticed how when people attack me personally as you have just done, that’s okay? For example, it seems to be just fine for the usual schlubs and schlemiels to get on my case for recommending speakers, and they always do it in the most childish boring direct way imaginable. Like, scroll up, "millercarbon always about Tekton."

What is that like, third grade? No. Actually a lot of third-graders write better.

Me, I take the time to craft clever prose, which you must admit Ohmmmmm had to crack you up, at least a little. Probably more than a little. And the guy in question, he’s always going on about how great Ohmmmmmm are, you get the same perfect sound anywhere in the house. So he must be in a trance. It’s not useful to know? It must be stated in the same plodding style every time?

Consider creativity! Celebrate diversity! Or if you find that too hard, well at least maybe not be such a schlub?
millercarbon,

"What is that like, third grade? No. Actually a lot of third-graders write better."

Hanging around school playgrounds a little too much?

To craft your clever prose a little more readable, how about this...

"What is that like? Third grade? No. Actually, a lot of third-graders write better."

Looks better? I know, you may need to stay practicing during recess.
This is just my guess. I think that to a certain extent they consider the room size a certain design is optimal for. I don't think they would expect a customer to use standmounters in a large room, for example. Same as you cannot use a Tannoy Westminster in a tiny room. They don't go as far as providing room measurement specifics since it may cause audio nervosa and potentially turn away some customers because their room does not measure 15 x 15. 
I am not sure how they go about sizes, but they do not seem to care as much about speaker placement and room treatments as Audiogon crowd does...

I am of mind to say larger speaker size should get along with smaller and larger living type rooms.  SQ in a smaller room can readily handle a larger high end speaker.  
I don’t want to know sound is coming from speakers.  Larger speakers do better filling room. Secret is to get speakers away from walls, and smaller rooms limit this.  Just want sound to fill room, hate dealing with sweet spot issues. 
in fairness, this is not universal.  Scansonic literally offers guidance to us and to consumers on what type of room to use each speaker in and as you rise in their line, the recommended room size increases.  

I am sure there are others, but this one in particular springs to mind.  

As a speaker maker, I don't want to "limit" who will buy my speakers but in the same token, if someone comes to me and says they want to use my speakers in a small room, up against the wall, I am going to tell them explicitly not to buy them.  All its going to do is make them unhappy.
