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.

What would be a good Subwoofer choice (12"), If my preferences were in this order: 1.) LOW FREQUENCY EXTENSION 2.) SOUND QUALITY 3.) SPL ? I have 800-1000w into 2ohms I only Need One Space is not a Issue I am using 8" MidBass 2 would be acceptable

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

Under a rock in Delaware

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.

Specs enclosed with the sub: Fs-25.2 Qts-0.55 Qes-0.616 Vas-47.70L Re-1.47(Parallel) Car Audio and Electronics Specs(December 2002): Fs-25.50 Qts-0.47 Qes-0.54 Vas-36.20 Re-1.52(Parallel) My specs via WT2: Fs-36-37 Qts-0.68-0.76* Qes-0.78-0.87* Vas-33.43L-40L Re-1.6(parallel) *Qts-Qes variations are probably because of testing in series and parallel that i performed and recorded but didnt make a note for my self of which was which but it is the range of a number of passes on the wt2, Fs is in parallel

anyone have access to klippel id let them test it!

I think i am going to keep the pg ti12d and put it in a 2.5-2.6 cu.ft sealed and buy something else and compare them installed on the same amp in there required boxes.

How did yours measure because mine were way off of the manufacturers specs maybe double, something thats really not good if i were using there recommended ported enclosure( id either have one really damged sub or it would sound horrible). And when i did my research on the forums i was told by a number of people that the optimum sealed box is a whole cubic foot larger than the recommmended kind of like the new xxx. I Dont want to be told that a sub is meant for small enclosures just so they can sell a sub, and then when i measure it for myself it comes back huge! Either they are lying or they were talking about a half of sub. But im willing to bet it is the QC.

I got it from woofers etc during tax time, and i dont know if it was measured wrong(maybe i dont know how to use wt2) but the parameters dont seem like it would be good in a ported box( the ported box was, big and peaky on the low end) i dont want to use 6 cubes for one sub, though im willing to compromise my car for the install, a box that size is just stupid for one sub unless ur in db drag, i like to listen while driving not while in my living room

I decided not to go with the 8" for MidBass, Im thinking more like (ScanSpeak Revelator 18W/8531G-7"), or maybe along those lines. Will the 15 be able to blend with this if i were to cross it over at 70 hz-no less than 60hz, how would the enclosure effect it?

IM willing to build my car around my system.

I would like to go 30hz, maybe 25hz fundamental any lower i could get from transfer function/cabin gain. i am using a civic or tacoma

A SSA Icon D1 in what enclosure or alignment and what else would be a good choice i like to have a choice, for instance all of my parameters that i got from wt2 and the pg ti12d elite were a average of a lot of tests, what size Icon should i go with because i have had quite a few subs that were all the same line but the size was different and the parameters and performance were different, also i have only had experience with sealed enclosures because i havent had the balls to build a ported or bandpass, especially not ib
