6.5 woofer: application specific.

it's on "paper", computer simulated, tunnel visioned, jargon. many years ago i was victim to that approach also. until i learned better.

his playing with them was nothing to do with spl farting. it was music, wide band application. and he ran the DD's with no HP protection just to see what they are capable. infact, he even ran them full range.

No, it's scientific fact. My apologies for you not being able to distinguish between the two.

You will not find any woofer, EVER that deviates from the laws of physics. You are greatly mistaken if you think otherwise, as is anyone else.

Linear displacement has always, and will always, determine linear output, when you compare drivers in a similar alignment, and especially if you are comparing wideband output capabilities, with distortion being considered.

Every single facet of a driver is dictated by physics, always has been, always will be.

I don't doubt that the DD has better midrange and upper midbass performance than the 6w0, as the 6w0 was never designed with those applications in mind in the first place, but in terms of low frequency output, the 6w0 isn't going to be bested by the DD.

I would NOT recommend the 6w0 for this user's application, as it is not a midrange. The Extremis however wipes the floor with the DD in all possible ways. There isn't even a comparison between the two.

Now don't get me wrong, the DD is a nice midrange for a conventional overhung design, but it doesn't really compare to more sophisticated topologies which yield flat BL across their excursion range. Couple that with a nice copper sleeve on the pole piece and a lower inductance even before considering the sleeve, and the DD really cannot compete. If you think that's "just on paper", then you have an even poorer understanding of loudspeakers than I originally estimated.

I realize of course many DD users greatly dislike rational scientific analysis of drivers, as such analysis typically does not paint Resonance products in a very flattering light. I suppose that's because science is "tunnel visioned."

lol, you're too much. assume what you will about me in your misconceptions. i have no desire to share with you what i have or haven't been exposed to as far as speaker design and building goes.

have you tested the W6.5LT to see what it's about? if it's before about sept or so, you haven't used the newer one i'm referring to.

go get it and check it out your self. as for me, as soon mpyres components are ready, i will have both the 65x and the 65m in my possesion to play with. and i have no qualms about giving credit where credit is due when i run them against each other.

i don't have a single track mind for any one particular brand as you suppose. i like what i like for the performance it gives and the purpose it serves. ohh wait, i need to hurry and put DD stickers on the cones of those other brands of speakers i own also. don't want any one to find out i'm not narrow minded.

ps- i never denounced the laws of physics. only incomplete formula's.

well im glad some people got to the thread before it disappeared to the next page lol.

i like all the ideas ive been given, but i guess the most difficult part of this is which one will most compliment the rest of the dls 3-way system. i knew from the begining i should have gone with the 6.5's but i didnt. im very happy with the mid/tweeter output, the are positioned well and sound very nice. but it seems that the midwoofers in the kicks just arent doing it, cant blame anyone for myself for that.

i'm still looking and i want to see where things go. i guess the draw for me was looking for a replacement speaker that i will be able to feel the bass on my legs when driving, i need some "ummph" behind those speakers. as i continue to look im giving my setup more time to break in and give it a chance.

Im going to look into the AA mids, what how do you think they'd compare to the IDQ6's??

Im like the Mpyre65, the AA 65, and the IDq6's. I may just have to buy a pair of each to try out.
