JL 13W7's

Discuss..

I may be getting one from a friend for $300 in mint shape. Looking for a loud sub that remains civil enough for daily driving/rock. I know install is 80%, but woofers make a difference. I have a 12" SX, its loud as all hell, but a little harsh to me.

... my friend has 2 of em, each powere by a 1000/1 with a kinetic 1800 (i think) in the back, and a kinetic under the hood, in a slotted box about 4 cubes internal in a ranger... and this is by far one of the loudest and cleanest sounding systems ive heard in person. Hell, it rattles my brain and made me shiver... and this was with the windows up. With em down, i couldnt stand it too long.

I like the way it sounds, i want to find out the positives and negatives about the sub... i.e. what kinda box it likes, how much space... etc.

regardless, 300 for a mint 13w7 is a good price.

I'm no expert, but I'd say for $300, it'd be hard to beat the 13w7. My friend has a 12w7 and it's definatly LOUD. I want one myself but can find a good deal. But I'd take it for $300 for sure. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

i absolutely despise the sound the subs make its a hollow sound for lack of a better term... same sound the old XXX makes... but for that kinda money pick it up and sell it on the ebay //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Let's just say I prefer the sound of the W7 over the sound of my L7. //content.invisioncic.com/y282845/emoticons/blackeye.gif.66a1670f5aaf7f406e783a63e3387dc5.gif

But I know what everyone means when they say W7's sound "hollow". But like stated before $300 is a deal. You could always sell it to me for a small profit just becuase you are that cool of a person... //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

$300 or a 13W7 is an excellent deal. I've never listened to one but even so, they could just be re-sold for a small profit if you didn't like how they look.

u sir are an idiot, whatever you claim you hear is your inability to design a system or your lack of application of music/sound/low distortion.

please try again.

***YOU FTL***

....get out of my thread nub.

nub? Who is the one asking if a W7 is better than an RE SX, have you even looked at your subwoofer before?

Sell your SX and buy a real driver, thank me later. Oh ya, its 100% install idiot.

Hoffman's Iron Law states that the efficiency of a woofer system is directly proportional to its cabinet volume and the cube of its cutoff frequency (the lowest frequency it can usefully reproduce). The obvious implication is that to reduce the cutoff frequency by a factor of two, e.g. from 40 Hz to 20 Hz, while still retaining the same system efficiency, you need to increase the enclosure volume by 23=8 times! In other words, to reproduce ever lower frequencies at the same output level you need an extremely large box!

 

However, box size isn't the only variable… You can continue to use a small box by accepting a much lower efficiency. In order to retain the same sound pressure level (SPL, meaured in dB's), though, this requires both a very large amplifier and a driver that can handle a lot of power and move a lot of air (requiring high excursions). Furthermore, it must be able to do so with minimal distortion. This is exacerbated by power compression, a phenomenon where the power heating of the driver's voice coil results in a non-linear relationship (read "distortion") between the electrical power in and the acoustical power out. Another variable not often mentioned is bandwidth… You can provide the perception of violating Hoffman's Iron Law by using a bandpass design, which can provide a lot of bass primarily across a very limited bandwidth. In all too many bandpass designs, the impressive bass is produced around a single frequency. This is often referred to as "one-note bass". It can rattle the furniture and impress your friends, and may even be OK for sound effects in action movies, but don't expect too much accuracy when listening to music with a lot of low bass content.

 

Summarizing, Low-frequency capability, box size, and efficiency form the three key aspects of system design. To increase any of the three, you have to give up something from the other two, with box size being the most sensitive. The often unpopular bottom line is therefore to plan on using the largest box you can comfortably live with. This partially explains the popularity of subwoofers, which can be both large and hidden from view, and often include their own built-in high power amplifier.

The W7 owns the SX in BL product and linearity all night long... just like me + your mom = all night ...

all night

Your thread is over, now stop posting and buy the W7 for 300 bucks.

STFU NUB. What is the title of the thread. "JL 13W7's"

Did i say, "which is better, RE SX or W7?" FUCK NO! Shut UP! Jesus. Nobody wants to read your "I googled to look intelligent cuz im a nub and don't know any better" responses. No its not 100% install, or everyone would use pyle subs. End of story. Go take your sony equipment and "thump" at your local Pep-Boys.... with your 100% install system.
