I'll ask again...where are your mesurments ?... If you have none with your use of the 8060's my post stands.

The 4.5 drivers are mid drivers....do research on the deftech's then validate your reason why...thanks

The built in "subs" kick in below ~130 hz and the 4" drivers are never tasked with high spl/low frequency duty. Ever. Even set to large. (It's like nobody even reads...rolleyes.gif)

Josh, yes, I've done the measurements, I'm not foolin ya, and have no incentive to.

Those numbers are usually unobtainable. They do rarely exist but they don't exist for the vast majority of all speakers that people talk about on these forums.

Of course you can try to prove me wrong and correct the data I post with the results of actual tests. ;-)

You seem to be the one to need to ask about the numbers....your numbers don't pertain to the 8060's and you've not done your own tests so I'll say again your numbers are basic numbers and don't reflect numbers related solely to the 8060's....just a basic accepted theory as you put it.

It is true that my numbers pertain to imaginary 8060s that use SOTA drivers. I've repeatedly asked you to provide more accurate numbers and instead of doing that, you keep making impossible demands.

I've revisited my analysis and found some real information about the 8000 series drivers here: http://www.definitivetech.com/downloads/Bipolar%20White%20Paper_newLogo_2012%20web.pdf If I apply this information, it drops my predicted bass versus frequency numbers for the 4 1/2 drivers by about 3 dB.

You should follow your own advice and research the Def Techs and you'll discover that I'm not pulling your leg. Maybe perform your own measurements. After all, I could doctor my results to support my claim, and how can you trust me? I could be one of those high paid forum schills for all you know.

In reality, I did those measurements months and months ago, had no reason to save them, and don't care to crack out the gear for a new reading just to placate your dumb ass. You'll just have to take my word for it.

I know the 8060 has 10 woofers but I still wouldn't set them to large. Speakers are placed for great imaging and not great bass reponse

Proper way to set the BP8060's

Set the main channels in your AVR or Preamp to LARGE
Run speaker wire
Set LFE to YES , If you have dual out's , awesome.
Run LFE to both towers.
Calibrate with Bass level around 10 o'clock. They tend to get a bit boomy after that. They are strong woofers and can fill a pretty big room with ease.
Set all other speakers in system including the powered center 8060 to small , if you can crossover the center to 40hz , this will make for a huge improvement. It can not reproduce frequencies below that well but you can run it in large and just miss he last end of the center info. I tend to use Small 40-60hz setting if you system allows , running it at 80hz is ok but it can cleanly perform well below that. The 8080 center digs deeper and I prefer it.
Surrounds to small crossed over at 80hz. This is where they perform their best. Clean and tight yet punchy and very dynamic.

This is a very good system and is fantastic for home theater use. No external sub required unless you have a very large room and at that point you should have got the 8080 system.

Hmm..OK claiming to do mesurments then not saving them seems counter intuitive and cussing at me does nothing except show your age...15?..maybe...so say what you will...and a post count of 12 doesn't help...prove me wrong if you like with more cussing I bet and screaming....thanks...and I own the 8060's so I might know something...smile.gif...and schill?...I'm sure....high paid?...doubtful.

Have you heard the 8060's in your room?...if not then your post is speculation...which is OK...just not fact...smile.gif

Based on your extensive posting history, it's clear you believe in magic wire, you don't believe in empirical methods to examine those beliefs, you deny perceptual science, and don't even have the ability to realize the weakness of support you provide for your own claims. You really don't have a clue, do you?

Sorry, bub, respect is earned, and so far you just haven't earned it.

Arny, or anyone else, I'll gladly PM you with my results, but I won't give the troll what he wants, other than the attention of this post.

So you admit you've don't results then say you've not saved them...then say you do have them and you'll P.M. others the results...credibility?... Keep your so call results private...makes no difference...and respect?...I've got that on here...you?...not so much.

No wonder folks became aggressive toward you in previous threads. You're a class A troll. I think your delusions about your reputation are only eclipsed by your delusions regarding magic wire. Anywhoo, welcome to the ignore list.

And your delusions about measurements...block me and call me what you wish...doesn't change anything...cheers...smile.gif

I don't have data...but again I'll ask you...do you own the 8060's?...and everything I've stated in the anti cable thread I've stated as my opinion...not fact...not once did I say I've got data to back up my claims...just my opinion of a product....get your facts straight before you accuse me of anything...thanks
post #51 of 59
Not accusing you of anything bud lol. When we did ask you about the wire facts you did say do the research:) just had to make a jab for fun!

Anyways most speakers are placed for. Imaging and not bass response so that's why I wouldn't set any speaker to large. plus id rather have the sub amp do the heavy work instead of the avr or speaker amp

I take it that you completely discount the predictive powers of accepted science.

The maximum acoustic capabilities of speaker drivers is set by their cone area and their Xmax or amount of linear travel.

Any test anybody runs on a real world speaker is going to be either a little less (SOTA speaker) or a lot less.(cheap speaker).

Deftech brags about having a high Xmax driver in their speakers but they also publish this:



The effect of BL curve on Xmax varies, but many use the 70% point. That's about 6 mm on this picture. Pretty good but does not compare with the 10 mm that Dynaudio claims for their 6 1/2 inch. Note that larger drivers naturally have proportionately larger Xmax for geometric reasons but that does not explain the big difference.

Dynaudio and Def tech are in 2 different classes. Both are excellent speakers IMO as I have owned both.

I don't know that that means: "2 different classes". Presumably you are using marketing-speak. Since I'm not selling anything there, my preferred dialect is technology.

As far as Xmax goes, it doesn't take spending a ton of money to get SOTA Xmax. One cheap but effective approach is to build a smaller speaker using the motor and spider of a larger speaker..

The most effective way to get good dynamic range at low frequencies is to use a larger diaphragm driven by a larger motor. Some place around 12-15 inches it is possible to use the largest motors generally available and have something like 30 mm Xmax.

I suppose so , not really wanting to take you off topic here. Comparing Definitive Technology to Dynaudio to me is Apples and Oranges , just my opinion. I see where your going with your posts , please carry on.

I had the 8060's myself. I took them back,I didn't like the metallic sound of the tweeters. Didn't like the looks either. Just do yourself a favor and just pick up some Martin Logan Electromotion ESL's and don't look back,that's what I did smile.gif Way better speaker anyhow. Add a sub ,set the xover at 80 and be done with it. You'll be in heaven.. biggrin.gif

If you didn't like the Tweeter and the looks of the speakers , why did you buy them?
post #59 of 59
Because I hadn't heard or seen them in my home. After I did,I didn't like them. I broke them in for 100 hours,and heard no difference. Now having said that ,I had them hooked up to an onkyo 805,now I have an 818. It might make a big difference,but even if it did,I don't like how they looked in my house.. For about the same price,the logan's are much better.
