First time buyer looking for insight
Your gonna want more lenses. Your gonna get in a situation with a walk around lense where you want to zoom in on something 50 feet away and you are going to run out of lense. Just like M5 said ur not gonna gain much in quality with a few mega pixels. It's all. In the lenses. You can see in a few of the pics especially the bird in the grassy water is a bit pixelated. That pic was taken with a 50-250m lense (50meters to250meter zoom) and I still ran out of zoom. That bird was only about 50 feet from me.

Get the 5500 and spend the extra money left over on lenses. You'll never see the quality difference between the Nikon and Cannon. However I personally like the The feel of the Nikon in my hands it's more comfortable and doesn't feel as cheap. If your not concerned about bracketing I'd even step down to the 3200 and spend even more money on lenses.

ShiZZZoN's Build #2 The Epicness of 2011-2024

ShiZZZoN's Build #2 The Epicness of 2011-2024
I don't know how the brake lights work on your car but every car I've worked on the brake lights are independant from the brakes. Do you have an aftermarket alarm? Maybe Maybe the shock sensor or such is is malfunctioning making the lights come on during acceleration. Or maybe the switch is at the break pedal is broken or needs to be adjusted. un screw it from its mount and shake it and see if your llights come on.

Need your input on frames/subwoofers...
I dont have plans for a pure spl sub, there just isn't a large enough market. However every MMAG motor will have the option of using a long coil to turn it into an over hung motor. For example I have a MMAG motor coming that when used as intended it's got a motor force factor of around 600. But with the use of the big 8 layer 100mm long winding it has a motor force factor over 3,000. Fs should not be an indicator of how low the sub will play. Especially when looking at small signal t/s numbers, your typical big sub on the market with a foam suround that has a Fs of 35hertz will in fact have a Fs of mid to high 20's with in it's working range.

simple to do really however, a sub that size would be massive in weight. You need a ton of motor force to control a sub with a moving mass of 4-5 pounds moving 3 inches one way 50 times a second. So, packaging would be excessive as well, including a wooden baffle that the sub would be attached to. similar to a JL w7's packaging. So you'd just use that as a templete.

standard OD sizes, but remember they are oversized cones so on the lower xmax sub's 30-35mm excursion you are looking at roughly 25% more cone area compared to conventional set-ups. If I eventually get into anything over 18" they will be oval shaped to stay under the window line of vehicles.

One coil I've got coming from Precision Econowind is and 8 layer aluminum coil with 100mm long winding width. Although its the largest coil they have built for a sub they estimate it'll handle well over 100,000 watt test tone burst. It is excessive for 99.9999 of use but I'd rather have the option there since time and money has to spent in tooling a custom connector to fit the frame anyway. It'll have adaptors like distrobution blocks do to allow the use of smaller wire. I am using FINEcone (fea program from LoudSoft) to design the soft parts to make sure they will be able to handle the xmax correctly. Once I have the soft parts made then we will do a rapid prototype of the frames to ensure no modifications will be needed.

Not at all it's only a few hundred bucks to tool connectors. And thermocouples are extreamely cheap to manufacture, only a few bucks.

Need your input on frames/subwoofers...
Basic math using ohms law. current = square root of watts/ohms so for 10,000 watts at one ohm you're looking at 100 amps. There are competitiors running 10's of thousands of watts. The maximum AWG current loads can be googled for different wire sizes. A thermocouple can be helpfull for people running more than recommended power, i.e. competitors. Heat causes the glues on coils to loosen causing the magnet wire to unwind. If you know the temp of the coil then you will know if it is safely handling the power being put to it.

...after all you are the ones who will be buying them. These frames will be used for subwoofers with an xmax of 30mm or larger and will handle massive motors. One of the motors samples I have coming is pushing 100lbs. They will be Osd (oversized sd) to allow for massive xmax and retain sd. After all what's the point if high excursion 12 if you have the sd of an 8. The below sketches are of what the frames might look like (have to do a few mods for added features. This frame has and OD of 12.5 inches and will allow a surround of 2.75 inches wide and still keep the same amount of sd as typical cones being used on current 12 spoked bakets. It has enough clearance for 90mm of one way xmax plus another 60% of clearance between xmax and xmech to assure no bottoming out. Its spider landing is large enough to handle a 11.25 inch spider. What I need from you are ideas you have always wanted on a sub but no one offers. For example these frames will use 1/0 wire connectors (with adaptors for smaller wire) and will have connectors for the option of a thermocouple built into motors to monitor coil temperature while in operation.

Icecream-Man Suburban
I can reach Alaska. And on clear nights I can hear a little Russian. I'm in south east Louisiana. I only get in it late at night. My closesst neighbor is about a mile away and it disrupts his direct Tv reception. It'll make the fluorescent bulbs in the house glow a little too.

Where to Deaden Front Doors on 2012 Fusion?
Beat on it. If rattles or resonates than apply to that area. If it don't resonate and you only need to stop road noise then u need MLV.

three sample motors coming with Ethos production
I have added the big MMAG to the list of samples. OD is 270mm just like the above overhung motor. I'm gonna use a 50mm long 8 layer copper coil as the standard coil. I'm also gonna try out a 100 mm long 8 layer aluminum coil. If it doesn't completely destroy the softparts ill offer it as a SPL coil.

It's really pointless to use Small signal parameters to model the higher output subs that are being manufactured today as they don't acuratly represent the driver in its normal operating range. Due to the characteristics of the materials being used and the stiffness of the suspension t/s parameters will change greatly from 1watt (small signal) which will only move most subs less than 1mm compared to 40 or 50 watts (large signal) which is needed to get most subs in their normal operating range. For example you will typically see manufactures recommend 1.5-3 cubic feet for a 12 but when you model the t/s parameters you come up with a figure around 1/2 cubic feet. The reason being is the creep factor of the suspension and surround on the sub. Most suspensions aren't too bad and doesn't affect parameters a whole lot but the surround does. The typical wide suround's Fo is in the mid 40's at 1mm but in normal operating range can be in the high 20's. The cone's Fo is directly related to the sub's vas which is directly related to box volume. So this sub which will measure say at 45 hertz Fs at 1mm will have Fs of 30 hertz in its working range which in return can increase vas from say 15L up to 25L which is why the sub works well in 1.5 cubic feet but when modeled the program tells you that you need .5 cubic feet.

Stetsom Service
No, caps charge and discharge almost instantly. The spark you get when you first hook up a power wire, that's the caps charging. They will remain charged (or charging and discharging if operating) as long as main power is applied and keep charge for a while even when main power is disconnected.
