how would one sound? they are kinda pricey so im trying to decide if one would sound good inside my car or if i should get two of another kind.

 

What is the size volume of the box you're going to mount it into?

The box size can make or break the sound of any subwoofer.

 

i was going to get one of the ones off of ebay that you can put under the strut bar in the trunk

 

The W6 woofer has been rated the number one sound quality woofer on the market. It sounds great and provides a decnet amount of Spl.

 

If you're talking about the Zenclosures $99 box here's a chart for the math. I measured 0.75 cu.ft. and went with two woofers. The 10W6 isn't a very bad match but not a good one. It all depends on what kind of response you want from the speakers. The 0.96 Qts will give you a bit of extra bass - follow the red line on the above graph.

I went with the nearly identical and twice as cheap Infinity 10.1dVQ and got an extra bit of bass response for the savings. The Infinity's F3 is 42 Hz, the JL's is 48. I doubt I'll hear the difference but that it a bit of an octave down that low.

The Infinity has about 6 dB more effeciency meaning you'd need an amplifier four times the size to make the same SPL level with the JL's. Getting a more sensitive speaker is a whole lot cheaper than getting four times the size amplifier.

 

hmm thanks.. so the infinity and the rockford fosgate are the two that would sound the best. what kind of amp are you using also.

 

I have a w6, my box is 2.3 cubic feet ported and t sounds bad ***. best sub Ive had by far.

 

In theory 0.707 is the flatest sound you can get. Any thing above that or below that changes the sound from way the recording engineer recorded it. With today's music that's a good thing. Faithful sound reproduction really isn't needed or desired with rap music. 15 dB worth of gain in the bass region - not enough!

I know the sound that I'm looking for and that's been in speakers with a Qts of 0.9 to 1.0 - that's my music, my ears, and my tastes.

YMMV.

Check the F3 - the point where the woofer's response is down -3 Db to get another reading on how much bass there is. I balanced cost, Qts, efficency, and F3 to pick my Infinity 10.1dVQ's.

There isn't a right or wrong speaker within a certain range. Manufactures like JL make a wide range of speakers designing them for different sized boxes on purpose. You can normally find their recommended sized box information on their web site.

 

I went with Infinity amps as well.

Electronics don't sound - it's really hard to hear a 50W from a 50W amp by another company once the gains are adjusted to match.

The Infinity's had the best wattage output to dollar cost.

My subwoofer is the 611a which is watts too many output and the four channel is the one that puts out 111W x 4 which is nearly too many.

 

LMFAO.. are you kidding me. Is this a joke? I am not trying to be a ***. But you cannot seriously tell how a sub is going to sell by charting it in Winisd. By your little charts one would think the Infinity as well as the Rockford would sound better. In real life application the W6 will sound much cleaner then both of those woofers hand's down. I am not bashing on either rockford or infinity But its the truth. They are not in the same league as the W6. Ask anyone who truely knows SQ or car audio. They will tell you. Infact head over to elitecaraudio.com and ask this question. Bar graphs and specs mean nothing.

 

I am not familure with the measurement of "cleaner" - would this be a lower THD across a given frequency band driven to a certain SPL? (**** enginers)

Don't argue with me, argue with Thiel and Small.

There are a whole lot of people who will argue that a $1200 woofer has to be better than a $600 woofer. These people can't hear worth a damn anymore because they've blown their freaking ability to hear. I have heard plenty of people with $5000 systems that sound quite frankly like carp because they've mis-matched gains, Thiel-Small parameters, got their crossovers jacked as poorly as their parametric, mounted their speakers in poor locations, have their speakers out-of-phase ....

When I'm done with my system I'll run a calibrated lab mic and do some RTA on the system to see just how badly I've done. Numbers, science, and engineering can only go so far - agreed. If the Infinitys don't match the rave reviews that I've read and my listening experience in the local car shop then they'll get **** canned. Where I work I can tote out whatever I need to test my stuff ...

Funny you missed the disclaimer where I said that your mileage may vary (I did say that didn't I?). I would hazard a guess that your not me, that you don't enjoy my calibrated ears, my music, my listening levels, or any thing else. But we both live in the same world governed by the same laws of engineering. Laws that aren't broken. The work of Thiel and Small has gone down in science - those bar graphs, charts, and figures are used by every manufacture on this planet that sells speakers (I would hope!) including JL Audio. It is possible that someone will come along with more acoustic laws to better describe the driver/box interface but I'm doubting it.

You can't argue these pure science laws. But whatever floats your boat - they are your ears, SPL levels ... etc. If there were only one set of ears that we all shared we'd all agree on the same set of speakers (which would be Klipsh Corner Horns or possibly La Scallas for the poor people).

I will agree that it's possible at some stupid loud level that the Infinity or Rockfords will be driven into higher levels of THD - first off due to the measured fact that the Infinities are nearly 6 dB more efficient. After a few hours of those levels it won't matter any more so same it. I'm not into "competition" but I did the engineering (cheating!) that earned two of the guys who worked for me in the Pugent Sound area first place SPL levels in their class. When listening to the JL's next to the Infinity VQ's I liked the sound of the VQ's (YMMV).

I've got next month's car payment in cash that says I think the Infinitys sound better than the JL's ... want to bet?

As a profession broadcast television engineer I happen to value my ability to hear, and so does my employer. While living in Japan I was able to purchase equipment directly out of the downtown showrooms of Yamaha, Nakamichi, Akai, Pioneer ... and did so for about five years. I spent weeks auditioning my investment in speakers carefully comparing speakers pairs against each other - one pair at a time verses one other pair. The manager of one audio showroom allowed me to come in after closing hours to battle the best American, Japanese, and European speakers in his custom made listening area.

Speakers are now the only personal part of a system purchase. It use to be I'd include record cartridges (needles) in that area but they are getting hard to come by. Listening to incredible sound pressure levels is like looking into the sun ... it damages your senses forever. In my home system I have a VMPS "Large" woofer with a Yamaha M-60 amplifier - the thing will peel paint but it rarely sees 10 watts worth of power as I plan on remaining employed in my chosen profession.

I argue with people about analog verses digital television quality. Analog TV has about 260 Mb/sec of data - "quality" high definition has about 8 Mb/sec. People listen to CD's or worse, MP3's and rave about how "good" it sounds while comparing it to nothing else. Have a listen to an analog recording from a vintage Akai GX reel-to-reel or Nakamichi three head deck playing back metal tape. The sound of a 12" virgin vinyl half speed mastered record simply can not be reproduced with an MP3 of any quality. All these people argue from their point of view that the MPEG video signal is great and that the MP3 audio rocks ... whatever.

I would trust that you're not of that ilk correct?

Buy the speakers that you enjoy, not what 9 out of 10 certified audio engineers enjoy, not what all the cool kids are using, or even what I say - PLEASE! For goodness sake do not buy a set of speakers without auditioning them - to do otherwise would be like buying a car without a test drive. Bring your music in with you and spend some time going back and forth between pairs - just do a couple at a time. Beware that you'll have to match the gain of each amplifier to match the speaker as a louder speaker can sound better. Also the mounting location of the speaker will vary the performace (see Thiel-Small ). 28 years ago I installed one of the first ABX systems in Chicago (AutoComm Electronics) - you need to find a similar type of A/B/X system to audition with.

You will not however do better than to follow the Thiel-Small calculations, those "little charts", when matching the driver to the box. The JL 10W6 is a good fit for a 0.75 cu.ft. box, as is the Rockford and the Infinity I highlighed in the little chart above.

Listen to those three as a start at least.

 

I do appreciate a educated response. Your right, everything comes down to your own personal ear. We can sit here and bicker all day long about what sounds better but like you said.. I bet you 600 dollars that I think the w6 sounds the best. I have just personally sold all three brands for several years and know what 9/10's of my customers prefer. While the infinity is a nice woofer the reproduction is not to the level the w6 is "in my personal tests in various enclosure sizes.
