Does this look like a scam? http://cgi.ebay.com/ws/eBayISAPI.dll...m=140360494826

Supposedly its 1 sub and the box.

 

shitty box

 

the pro wedge is shitty?

 

What about http://www.rtboxes.com/catalog/product_info.php?products_id=1091{5}219

 

Tuned way too high

you wanna be tuned around 32-34 for a daily box

 

Prob shld just get http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT

and let a local shop make me a custom enclosure.

 

w6 would be a nice choice

i'd still go with the q though since it can dig lower and get louder

 

They will perform slightly different in the same enclosure. This is due to the changes in the voice coil to achieve the different impedance options. However in an optimized enclosure, SQ should be identical. Or at least any differences should be inaudible.

 

Not the IDQ, right? I was told by one of the guys at ID himself that the W6 will outperform in nearly every way.

But in the end I've learned just how important the box and setup is. My W6s were a little disappointing until I finally got them setup just right for the TL (the bandpass). But now some people think I've got 8s or 10s in there with rock with the punchiness and can't believe how deep they will dig on rap. The range is truly amazing. Thanks to CSW Biggs for that.

Eggy, I wish you lived in my area. I think you would be impressed with it.

 

Nah..fi q

I love the w6...just think the q is better.

 

I've got a buddy of mine that's a huge fi fan. Haven't gotten to hear his new system but I'm looking forward to it. In fact, I would like to write a completely unbiased comparison once I do hear it. However it will be in different cars with plenty variables so you know how it goes.

 

which fi is it?

 

Where's Bakersfield? I'm in SW Ohio, but drive all over the midwest for car stereo competitions. I'd love to hear your setup.

 

It's in central California. I know it's far but if you're ever in the area, you're more than welcome to hear it and I would like to hear yours. I'm always looking to improve on my own system so anything that puts mine to shame is welcome.

 

Oh bummer... That's quite the drive... I guess it depends on whether or not I can find a competition that would make the drive worth it...

Yikes!

 

Mine: Total Travel Estimate: 32 hours 51 minutes / 2219.08 miles

 

i grabbed a jl 500/1 amp for 150 shipped. Now just gotta decide on the jl 10w6v2, 10w7 or the fi-q 10 inch. All depends on the prices i can get. Gonna try to get a used one in great condition.

 

You'll be more likely to find a Fi Q on a car audio forum. The biggest classifieds section online (that I've seen) is at caraudio.com.

 

you can probably sell the 500/1 and get the 1500d

 

Would you take the 10w7 over the 10w6v2? I might be able to get a w7 for same price a w6v2 would cost me. My main concern is that 1 10w7 is same weight as 2 10w6v2 and i dont want to add that much weight. I could always take the sub out tho for track and autocross events.

 

w6 is better

 

ill jump in on the travel time bandwagon Total Travel Estimate: 36 hours 18 minutes / 2434.84 miles straight line across the country bishes I also vote for the 1500d

 

To the OP; from someone who knows a lot about subwoofer design I can assure you the W7 is better than the W6 (hence the higher number). It will have more output capability, better low frequency extention, and better SQ. So unless you are looking for a shallower mounting depth or a tad smaller enclosure requirement, the W7 is the way to go.

 

i wanna know how the spl woofer has more sq than the sq woofer in the line..

 

Why do you think it's "the spl woofer"?

Here is why it is a better SQ sub:

1. Cross-drilled holes in pole vent: Although these are stated to be used for cooling (mainly due to possible patent infringement if they specified their true useage), they actually help reduce stray flux in the magnetic gap. This linearizes the BL throughout excursion and therefore reduces 3rd order harmonic distortion. Here is a DUMAX report of a 10W7 showing this in effect: http://www.adireaudio.com/Files/JL-10W7.pdf As you can see the BL curve is pretty consistent with excursion. Here is a DUMAX report of a standard overhung motor: http://www.adireaudio.com/Files/IDMAX.pdf As you can see, the BL curve is very parabolic. This means that BL decreases with excursion exponentially which produces distortion. These changes in BL with excursion are responsible for about 70% of the distortion produced by a sub operating within it's linear range.

2. Excursion: Having higher linear excursion benefits us two-fold. First of all, it keeps the sub operating in it's most linear range for a given output. And as mentioned above, higher linearity means less distortion. Second, it is useful for low frequency extention. For every halving of an octave, excursion must increase by a factor of 4 to keep the same output level.

I've installed many W6 and W7 systems at work. While the W6 is a very nice sounding subwoofer, the lack of distortion in the W7 really gives it a unique tonal quality over the W6.

 

I respect your opinion but I disagree.

Watt for watt the W6 is louder. It has a more detailed bass and definately better SQ. Of course throw the W6 in an average box and the W7 in a good box and the W7 will beat it in every category. They're not that different sounding with the main difference being the power handling and excursion. I've fallen in love with a properly designed bandpass box for the W6, something you can't do with the W7.

I believe in keeping excursion to a minimum for SQ which this bandpass accomplishes.

I'm not for a second saying the W6 will compete in SPL or that there's much of a difference in SQ.

 

The w7 is not the spl woofer in the line? do you know the normal power handling of sq woofers? go look @ any sq oriented sub from the lines of focal to morel, most are rated @ 300-600 watts.

 

lolz yea man come on the w7 is spl and w6 sq maybe sql like said

 

i ended up buying a 3 month used in perfect condition 10w7 from someone for 250, so too late to get the w6 now. Im sure ill be happy with it tho.

 

Nice....now build a nice ported box for it.

 

Keep in mind that with a bandpass enclosure, you aren't technically hearing the sub as it is tucked away inside the enclosure. What you are hearing is the output of the port.

When discussing SQ, I think there are two different points of view. You have objective SQ and subjective SQ. The latter is completely someone's opinion which isn't very helpful for your own choice. How do you know someone elses experiences, goals, hearing abilities, or tastes match up to your own? When I worked at Adire Audio, we used our own patented motor topology in our Brahma that had the same results of low distortion like the W7. While most people absolutely loved the SQ, we did find some that didn't like the sound of the sub. They were used to subs with decent levels of distortion and they found our sub to sound dry.

Objective SQ looks at the data available to find which has the highest fidelity. Fidelity of course is being as faithful to the music as possible. This IMO will be of the most help to someone actually looking for a great SQ sub.

Now I've provided objective evidence proving the W7's superior fidelity to the W6. All I've seen from the other side of the argument is subjective opinions. You guys are more than welcome to your opinion that you like the W6 better. Just know that the W7 is JL's top SQ sub from an objective standpoint.

 

So if you are basing your definition of SQ and SPL purely on power handling, then tell me how having a lower power handling makes a sub sound better. Keep in mind that a power handling rating is just a made-up number that often times is based more on marketing than actual performance. JL is widely known to be very conservative with their power handling ratings compared to their competitors. Also we are talking from 600w to 750w. Does that extra 150 watts of power handling really make it an SPL sub and not an SQ sub?

The Brahma, which I mentioned above, is still highly regarded as the best SQ sub many have ever heard. And it had a rated power handling of 1600 watts RMS. This was devised using the IEC 268-5 test method.

 

Thank you for the insight. Of course mine is subjective. I have no way of measuring it so it's an opinion based on what I've heard.

I would not say that the W7 is not an SQ sub either.

I've never heard a W6 and W7 under the exact same conditions but in the setups I've heard, I prefer the W6's sound.

Your points on the build of the woofer, wouldn't they make a larger difference at higher excursions?

There is a graph somewhere that CSWBiggs posted on here of the frequency response of this bandpass. I'm not sure if that's the sort of info you're looking for but it was pretty much perfectly flat in the region it's being played in.
