DANGERDAN Posted August 18, 2011 Posted August 18, 2011 Im sure this has been covered somewhere but i could not see anything, from measurements taken on my system it actually looks to be 7" in diameter including measuring the suspension. Whats this all about exactly that makes them 8" on the specification table ??. Quote
pite Posted August 18, 2011 Posted August 18, 2011 Can you describe, how you measured it? Out to out of the woofer basket frame or just the woofer? Quote
DANGERDAN Posted August 18, 2011 Author Posted August 18, 2011 From the circumference of the suspension not the basket itself, with the basket its 8" but i would have thought that when stating woofer size that the measurement would be from the actually woofer cone itself and if anything the suspension as well.

pite Posted August 18, 2011 Posted August 18, 2011 I think, it's basket what they use in the measurement...I don't know if it's like this from begining or changed at some point in AV world some time ago! Quote
DANGERDAN Posted August 18, 2011 Author Posted August 18, 2011 Couldnt that mean they could increase the basket size to a much larger size and then promote fake information on the build material ??. Quote
pite Posted August 18, 2011 Posted August 18, 2011 Couldnt that mean they could increase the basket size to a much larger size and then promote fake information on the build material ??. Yes, they can...But there comes other very important constraints! The designers has to weigh in the resonance of the speaker basket, weight increase, width of the speaker, etc. And thus, it wouldn't help them! The thing which certainly helps them is that instead of saying 7" speaker (the size of the woofer cone) they can say 8" speaker by adding the 1" worth of basket frame in the diameter! Quote

On that note, I'm pretty sure that RF-7 II's woofer won't measure 10". The speaker including basket rim will certainly measure 10" - and hence the 10" driver! Oh well, IMO, RF-7 II sounds really nice with great authority in low frequency region! Quote
DANGERDAN Posted August 18, 2011 Author Posted August 18, 2011 Actually its 6" without the suspension 7" with and then 8" with the basket included, i dont mind that anyway as i like the thought of a the speaker being smaller as it physically can handling mid frequencys better then if it was a true 7 or 8". If someone could meassure their rf7/II and see what it is that would be something interesting to find if it is or not because it looks significantly larger than the RF 83's woofer with only 2 inches on it.

TNRabbit Posted August 19, 2011 Posted August 19, 2011 It's all advertising games. ALL companies fudge the size on woofers through this type of trickery. Quote
CECAA850 Posted August 19, 2011 Posted August 19, 2011 Men have been overestimating the size of things for years. Quote
Dingman Posted August 19, 2011 Posted August 19, 2011 Men are certainly more visually oriented than women. Thus the difference in perception that you refer to. Har. Har har har. Quote
Dingman Posted August 19, 2011 Posted August 19, 2011 I agree. Used to have a buddy in advertising. He freely admitted to taking psych classes to learn how to cause specific responses in consumers. Here's the kicker... he said he often just resorted to lying. Often hard to check the facts and even harder to make people care he said. EDIT: I don't know if you allow political comments here, but my buddy also frequently remarked on the excellent "fear" campaign that GWB used. Apparently, the fight or flight response is not something easily resisted but it is easily triggered and was used to great effect in the campaign. EDIT02: apologize for hijacking thread. It's a habit and actually an art, tho under appreciated. Quote

CORRECT, THEY DON'T ALLOW POLITICAL COMMENT.I have many opinions on a whole host of political issues, I'm certain the forum as a whole really don't care to hear./read Quote
GBShade684 Posted August 22, 2011 Posted August 22, 2011 I noticed that as well when I got my RF-82's. I have yet to actually use them, so I can't say whether I appreciate this small fudging of the numbers or not, but I was kinda disappointed when I pulled out the old tape measure. Quote
pite Posted August 22, 2011 Posted August 22, 2011 Well, one thing is that they state 'Driver' size and not the size of the specific component of the driver, e.g. cone, toroidol, basket, etc... I think, as a customer, most of us are informed or can research to a depth one wants and decide which speaker to buy... Not trying to favor the manufacturer, but, at this time, it's almost a industry norm! Quote
GBShade684 Posted August 22, 2011 Posted August 22, 2011 Just something that kinda shocks you as a first time buyer. I don't think I would have even noticed if it hadn't been for my brother in law pointing this out. One more piece of knowledge aquired by experience I guess... Quote

If someone could meassure their rf7/II and see what it is that would be something interesting to find if it is or not because it looks significantly larger than the RF 83's woofer with only 2 inches on it. For RF-7 II the measurements are as follows, Woofer Cone: 8" dia With Suspension: 9" dia (With Suspension Frame: 9.5") With Basket Frame: 10.5" dia Oh well, I knew that the 'woofer cone' is not going to be true 10" in diameter when we bought it...
