boy.kroy

Oh thanks now i understand i guess i should have looked at someone elses post before taking pics and posting, sorry for wasting eveyones time.

but if you must close it sorry and please dont ban me i have no clue what im doing i dont even have a digital camera someone let me borrow theres

Im sorry but i dont see a thing for attachment i only see insert link and insert image and the both require a url, sorry this is my first time posting anything in the classifieds

there is a link in my post for pics https://picasaweb.google.com/def.soundz/ForSale?authuser=0&authkey=Gv1sRgCPf2wIHIp4qs6QE&feat=directlink

I know this is an old thread, but you cant use the IB3 in a Scion XA Because you dont have a trunk you have a hatch, and that sub is Infinite Baffle Only which means you need a trunk!

By The Number of RCA's Im assuming the six channel

How much will it cost if i miss the pre-sale and order after May 1

Any one have any experience with Zuki Eleets Amplifiers

Does the FI Q have any Shorting rings, do you guys use rings on any of your drivers

The mechanical components in typical speaker drivers may change over time. Paper, a popular material in cone fabrication, absorbs moisture easily and unless treated may lose some structural rigidity over time. This may be reduced by coating with water-impregnable material such as resins. Cracks compromise structural rigidity and are generally non-repairable. Temperature has a strong, generally reversible effect; suspension materials become stiffer at lower temperatures. The suspension also unergoes changes from chemical and environmental effects associated with aging such as exposure to ultraviolet light, and oxidation which affect foam and natural rubber badly, though butyl, nitrile, or SBR rubber, or rubber-plastic alloys such as Santoprene are more stable). Foam is highly prone to disintegration after 10 to 15 years. The changes in behavior from aging are rarely positive, and since the environment that they are used in is a major factor, the effects are not easily predicted. Gilbert Briggs, founder of Wharfedale Loudspeakers in the UK, undertook several studies of aging effects in speaker drivers in the 1950s and 1960s, publishing some of the data in his book, Loudspeakers. There are also mechanical changes which occur in the moving components during use. In this case, however, most of the changes seem to occur early in the life of the driver, and are almost certainly due to relaxation in flexing mechanical parts of the driver (e.g., surround, spider, etc). Several studies have been published documenting substantial changes in the T/S parameters over the first few hours of use, some parameters changing as much as 15%+ over these initial periods. Other studies suggest little change, or reversible changes after only the first few minutes. This variability is largely related to the particular characteristics of specific materials, and reputable manufacturers take them into account. While there are a great many anecdotal reports of the audible effects of such changes in published speaker reviews, the relationship of such early changes to subjective sound quality reports is not completely clear. Some changes early in driver life are complementary (such as a reduction in Fs accompanied by a rise in Vas) and result in minimal net changes (small fractions of a dB) in frequency response. If the performance of speaker system is critical, as in high value or heavily equalized systems, it is sensible to measure T/S parameters after a period of run-in, and to model the effects of normal parameter changes.

Some caution is required when using and interpreting T/S parameters. Perhaps first is that manufacturer values may not match individual units. Their values are almost never individually taken, but are at best averages across a production run. In addition, there are inevitable manufacturing variations across a driver's production. As well, driver characteristics change somewhat after they enter use. And so the T/S parameters which apply to a particular driver will be, to some extent unique and can only be found with certainty after a period of use. It is also important to understand that most T/S parameters are linearized small signal values. An analysis based on them is an idealized view of driver behavior, since the actual values of these parameters vary in all drivers: with drive level, with voice coil temperature, over the life of the driver, etc. Cms increases the farther the coil moves from rest. Bl is generally maximum at rest, and drops as the voice coil approaches Xmax. Re increases as the coil heats and the value will typically double by 270

Whats the difference between Fo and Fs

I thought that was a little wierd also that the Fs was the only Spec that Was way off, but the wt2 also gives a fo measurement that is more consistent with the factory Fs spec but i thought the Fs and Fo was the same thing.
