JL Audio W7 Subwoofer Driver

The W7 embodies JL Audio's commitment to pushing the envelope of speaker technology. It features over half a dozen JL Audio patented technologies - Including, an OverRoll™ Surround, W-Cone technology and a Floating-Cone attach method which are just a few of the JL Audio exclusive assets that set the W7 above any other "high end" subwoofer driver currently on the market. These drivers have set the bar for drivers wanting to provide the deep transparent lows of a Sound Quality woofer and the hard hitting power of an SPL sub. The W7 is able to provide its sublime sound quality and extreme output by efficiently dissipating thermal buildup and optimizing its staggering linear excursion.

Although the 8W7-3 Subwoofer can be driven with as little as 200 Watts, for best audio performance it is recommended to run an amplifier capable of between 400 - 500 Watts of continuous power per driver, like the JL Audio JX500/1D or JL Audio XD600/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosures, needing 0.875 cubic feet of air space in a sealed box and 1.00 cubic foot in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)

Every 8W7 subwoofer is built to exacting quality standards in JL Audio's Miramar, Florida factory. Each of the four models is a completely original design from surround to back-plate (even the bolts and screws used in assembly have been purpose-designed and manufactured to our specifications). Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

JL Audio is the ONLY option

Once you try JL you will never want to buy another brand again. I previously owned 2 JL 10" W3's and was very nervous about having to downsize my system because of space. This 8" W7 is amazing! W7 is the only way to go, especially if your looking at a little 8" woofer. This thing kicks @$$!

JL Audio 8W7-3

Bought 2 of these and built a slot port enclosure out of mdf according to the factory specs. I am using a 1000/1 v2. Just broke em in and they hit so hard for a set of 8's. All my rca and power cables are monster 400 series and the clarity and sq with these subs is amazing. Only downside is I need to go buy more dynamat. Make sure u get the bass remote. U need it for quick adjustments between rock n rap.

amazing

My order was packed and shipped the same day my order placed. Very quick arrival time. Extremely high quality product. The JL Audio 8W7 is AMAAAZING. Previously I owned two 10"W3's and was worried about having to downsize in my new vehicle to an 8". But JL has definitely pulled the rabbit out their hat! If you did not know that it was only an 8, you would guess it was a high-end 10 or a nice 12!

lots of power for 8

this is probably one of the most powerful 8" subs on the market. it is hard to believe it is only a 8" plenty of bass when hooked up to a 500/1. I like the tightness and quickness of the 8" sub compared to the larger ones.

ol yea, lil bulldawgs

If you think you need (2) 10's or 12's forget it.. I have (2) 8w7's on a PPI D3000/1 feeding it appox 1000w plus @ 1.5ohms talk about SQ/SQL.

Yea, the JL w7 line is expensive we all know that BUT when you have (2) 8's that sound better then (2) 10's/12's (maybe NOT louder but BETTER) thats when JL's quality shines. Port these lil bulldawgs and sit back and enjoy. One ported can do it, but two will be perfect. The key too these are properly tuned enclosures and feeding them nothing less the 500rms per.

I have these in 2cf after displacement, tuned to 34htz.

Great

I would recommend this sub to anyone. Top notch sound quality, low-end extension, and the impressive power handling of this 8-incher make dreams come true. Not cheap, but you get what you pay for here.

Great Sub!

Great Subs. I got the 8" to fit in my Dcab Tacoma. It sounds great for an 8" sub. Still fills out nice and low. It is in a sealed box and is very accurate and tight sounding. Very comparable to the old Rockford Fosgate HX2 Power series. Would by again.

Great sounding woofer... lots of output.

Awesome sub, well worth the money. Beats the 12" and 2 10" subs I had in my truck before and sounds waaaaay better. Have it in a slot port box.
