Now that I think about it, I had just came across a good bit of info from this site. http://whealy.com/acoustics/behaviour.html In that section, it speaks about diffraction. And just based off of that image you posted, I have a some what understanding of why that ring is shaped the way it is. "There are many more ways to scatter sound besides using rough or convex surfaces. In addition to identifying the effective upper limit for the transition region of a sound field, Manfred Schröder invented a type of diffuser known as the Quadratic Residue Diffuser (QRD). It is formed by breaking up a wall surface into “wells” of different depth." The ring around it, it has different groves and dips to diffract the sound, just on a smaller scale than the technique found in Auditoriums. At least this is my thought after the reading and looking at the image you posted.

150 at 33hz, jesus!

Incredible man!

He'll yeah!!

Yeah, during the last few weeks, a lot of my educational material has seemed to link me over there! Lol. No matter, the more Intel I have, the better understanding I have. Rather it be right or wrong.

This looks like a great read, thanks for the link!! I will study it sometime tomorrow.

You are being meaner on your doors with that choice Yes....and then the OP tells about wanting an audience to hear as well. This is a game changer, but also self defeating since your first post specifically asks for an SQ option. Good long distance and short don't mix. You are now picking for the ones outside the car and not the ones in. I could never make that choice or compromise. And this is exactly why I am still wet behind the ears. To my knowledge/thinking. If the response was good at short distance, it would/should be good long distance. Honestly, I've never thought about how distance could effect, or could be a compromise rather, in car audio realm. So to reiterate, the distance where you want the most output is a deciding factor/compromise to make when selecting a loud speakers? See, now that I ask that, lol, I essentially answered my own question. And of course, you can't have your cake and eat it too.

Also, I do not have the tools to model the off axis response of the beyma, I guess that would be a good start lol

awesome pics, in for vids

lol, the rms is not power handling, it is the thermal rating BUT, obviously, if you put it into a 20cubes box, and bottom out the piss out of it, or anything, you will damage. What I mean to say is, no matter the rating, a user can still very easily damage a sub at ANY power level.

Awesome!

I wouldn't worry. You wouldn't believe how stinky/hot I've seen these get, IN PERSON. Lmao. Last year was getting demo'd during Slamology. Buddy had 4 18 sp4's in a wall, and I swear, it felt like he had an heater inside that damn van from how hot/stinky the subs had gotten. No failure ever occurred though.

Grab some ZCONS man, or ethos.

Hey brother, Thank you so much for this response. I really did smile while reading this. Means a lot to have so much support from you and other members. At this time, the Beyma has already been payed for as of This past Friday. SBN 2014 is literally right around the corner, so I wanted to get these in and tuned prior. I have no idea on lead time for the Beyma's, not sure if they are already built or built to order. But again, I cannot thank you for all the help you have provided thus far. Once they have arrived, I will be uploaded a crap ton more content. Ahhh! Finally, some relief! lol. I really do hope that these work out for me. And to you Honda, as well as others, I know that, once I have these things mounted in and playing, that my response will not sound so good, nor will it be optimal. I Just wanted you guys to know that yes, I acknowledge all of the downfalls for mounting these in the doors. I did not want to make it seem as if I'm being hard headed or seem I don't want any further help, as that is NOT the case. Thanks to all the input, now I know exactly where/what to target once these are installed. I know where my weak points will be, and will attack them accordingly. Getting the Beyma within 45 degrees from the passenger door shouldn't be a problem, doing so from the driver side, WILL be an issue, I'm sure. So that being said, 95honda, //M5, Impious, J, and whomever would like to chime in. What is the best way to mitigate poor performance due to the listener position not being within 45 degrees? The driver has already been selected, so saying buy a better off axis speaker is not what I need to hear, as I acknowledge that already LOL.

WOOOOOOOOOOOOOOOOOOOOOOOOO haha, I"m so drained right now, will post full response tomor!

Louder than justins 4 18 evils?Do you know how many decibelz its doing im curious? Well, idk. It was extremely low, I will say that. On the meter, 6 ft away, he was doing a 130.x but at like, 25hz. Its not sealed from the rear, so, just imagine, a astro van, with a wall, but feeling all this pressure coming from the sides of the wall. Plus, no power. rumor is to be 16bc5500s and 40batts when its all said and done. His goal is to take down Steve Mick.So your saying my truck was 5db louder 6ft away with only 3 subs and half his power? And he wants to be louder than Mick? LOL Thats 12db he has to make up for. Sounds to me like Justins Blazer with the Evils would shit all over this build. Not hating on it..... just sayingLol. You must have missed the part where he said the pnp score was on 25hz. Doing 130+ at ( it was actually 27 hz) is absolutely insane! He just got some 16v batteries and there should be more updates soon. Ill text him now and see if he has pics. Yeah, 130db+ at 6 ft away at 27hz LOL

The Beyma does not have an phase plug.

Oh yeah, and if dualing demos is how you describe, horn loaded low end with the apeture firing out the back would decimate your opponent... About the only time I would suggest such a thing... Picture of what you mean? Haha. I would love to get some ideas.

Wow! Siiiiiick

Hey Honda, thanks for the input, as always, amongst every other person opinions. As stated in the very first page. I gave as much detail as possible. We, ssa, preach about listing as much details, goals, existing equipment, and orientation or whatever as much as possible. I listed all of said information, but yet, was still consistently pushed to go against what I was looking for. Besides a few, other members were against the idea. Which I understand, you are trying to help me to sound better, that's fine, I get that. But the size I wanted, for my goals, was given. I compete in MECA under Dueling Demos. This is new York style vehicle in front of vehicle where the crowd picks the winner. So yes, this includes booth doors being opened, with listener up to 50 ft away. So yes, output has a huge impact on driver selection. With the copy and past you've provide, this shows me that the cutoff goes to poop, that's fine, that's at 1250khz. I will not have my mid crossed that high. So this is not an immediate issue.
