what?

if it is directional at 60 hz then you have alot of resinance. yes a vibrating part can resonate at a higher freq than what its being bombarded with lol

gg links, stop posting, and cross your subs over at 200hz while you're at it...

12 inch mid bass probably had alot of output and last i knew richards midbasses were in the sides of the backseat of the gn...so whats your point?

*sigh* Even with direct quotes on the subject from two experts, you still need more instruction? lol Both the quotes made my point, if you refuse to see that that's your problem, not mine. Like juju said, Ive always found midbass to start becoming directional in the 70-80hz range.

starts but doesnt become for over an octive lol. also depends on what you put with it to pull it out to the sides //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif or isnt that not obvious?

Starts but doesn't become? You are really trying hard to not be wrong here, aren't you? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif If midbass STARTS becoming directional at that frequency, why would you wait an octave to seperate it?
I guess Richard Clark and Scott Buwalda and all those other SQ experts how no clue when they run stereo midbass below 200hz (even below 100hz). Because after all, midbass only 'starts' becoming directional then, it isn't really directional for another octave, right? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

BTW, you've changed your story quite a bit from your first post here on the subject. You now admit midbass 'starts' becoming directional before, but isn't really directional for another octave (whatever that means). You said that like you meant that all along, and yet your first post here on the subject said something quite different:

mid bass doesnt start going stereo until about 200 hz

lol crossed them over at 90 15's at that awwwwww that part of my bird didnt change that only netted a second place at usac and iasca world finals. then when i bought it and changed things around it netted 50 odd trophies from sbn to midwest nationals to regular shows. im not being a dick but im not clueless lol when you are doing a sound stage there are many things to factor in. not just "thats a bad idea". volumes, xover slopes, and positioning can change up things pretty radically. if you dont understand thats fine dont want to thats fine as well just dont preach about what you dont understand. if what i said had "no bearing" then why would scott even try that with a single 12?

Oh now Im the one who doesn't understand? You can't even keep your story straight, mr expert on the subject. Does midbass 'start' becoming directional at 200hz as you first stated, or below 100hz as you now admit after seeing a few others say it? You are squirming your best to get out of the mistake you made (saying midbass doesnt start becoming directional till 200hz), but its not working. No amount of tales of winning trophies will change that, sorry.

As for why Scott tried it, maybe he thought like you did before. But uhm, clearly AFTER TRYING IT he came to the conclusion I quoted. Would you rather take his word for it before he tried it, or after? //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

i didnt change 1 bit about any of my post/posts.

You want to change from a single mono midbass, to stereo midbass (good idea) but then mount them together in the center of your car? That's a good idea gone wrong. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Midbass should be to your left and right as you sit in your car, not just from the center.

Lol...this kid just REaLLY doesn't get it //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif...and I tried to explain it to him before...ho well

Really now?

(in reply to juju saying it starts at 60-70hz)
Clearly you;ve changed your story. Your words are still here for everyone to read, no idea why you are trying to deny it.

Im done with this thread. Have a great day everybody. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i know if he could read the graph on the link he would have answers and midbass isnt nowhere near cut and dry directional at 70hz just starts laying measurable hints measured via a mic not the human ear

 

[audioholic 5,000+ posts]

Yep, Scott Buwalda and RC are wrong, and audiolife is right. lol

Seriously, Im really done this time. Just wanted to add one last laff.

lol depends on form of measument via the human ear or a mic you can easily google your answer. to the ear people argue between 180-250 hz (probably hearing dependant) or you can go by the mic but realize when you do you dont hear nearly as well as a mic can measure.

lol nothing quoted by either of those people means anything to this. richard is talking about distances /(his car 2 big assed horns under the dash, 2 12" mid basses at the sides of the back seat, and 2 15's in the trunk). if anything what he said deams more about NON directivity than directivty. meaning DIRECTION means little as compared to getting the waves to WORK TOGETHER.

You are only focusing on the first of RC's quote and ignoring the second, and pertinent, part of it. He talks about the criticality of PLACEMENT of midbass. Isnt that the discussion here, mono midbass and/or midbass coming from the center? Quit squirming man, nothing wrong be with wrong once in a while. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
And well, if you cannot see the relevance of Scott's comment (a center mono midbass pulling imaging toward the center when it didnt even go up to 200hz), then you just dont WANT to see it.

I think its time to agree to disagree. cya
