I am planning to get these speakers and would love the audio gurus to comment on the same .

SpeakersJBL GTO948 Highlights
• Proprietary Plus One® woofer cones
• 2-Ohm high-efficiency design
• Edge-driven My-TiTM tweeter
• Built-in tweeter-level control switch
• UniPivotTM rotating tweeter on selected models
• New low-distortion, low-Q woofer motor


Features
New My-Ti Tweeter
• Stiff, light and with high efficiency, the new Mylar®/titanium-composite tweeter offers far better high-frequency
performance without the high-Q breakup mode associated with metal domes and cones.
Edge-driven tweeters
• With more voice-coil surface area to dissipate heat, these tweeters provide higher power handling than smaller balanceddometweeters.
Reduced nominal impedance
• The new GTO speakers have a nominal impedance of 2 ohms. Therefore, they extract all the power from amplifiers and head
units, which are normally designed to increase their power when driving 2-ohm loads. The actual minimum impedance of GTO
speakers is around 3 ohms, thus offering enough safety against potential overheating of low-quality BTL amps in less expensive
head units.
Low-Q woofer design
• The improved woofer parameters (lower Qts) offer good bass extension and better transient response in typical mounting locations (e.g., doors and rear package tray).
Plus One® (Patent Pending) cones
• By offering more cone surface than competing models of the same size, the new GTO speakers provide higher efficiency and better bass response.
UniPivotTM (Patent No. 6,002,780) Rotating Tweeter
• The tweeter is mounted in a 15° angle and can be rotated to point at the listening position. This leads to more uniform high-frequency response between left and right channels for speakers mounted in off-axis factory locations
.Built-in Tweeter-Level control
• Most models feature a switch to reduce tweeter output level to match personal listening preference or different mounting locations.

Can any of the audio gurus like Sam Kapasi and others please give your thought on this set of speakers.I am getting these for my swift .

I've only listened to the 938.
And they're real good.

Well thank you nitrous ji , Then I think the 948 must be a little better than the 938 also.
It looks good too. Wonder what the button on the speaker does .

[sathee46]

The button is for tweeter level control

Oh thank you for clearing my doubt , But still puzzled by what it does !
Purpose of the thing ? And when to use it ?

a quote from the jbl wesite

.....a switch to reduce tweeter output level to match personal listening preference or different mounting locations.

In other words to make it sound less/more brighter

Aah now I get it . Thanks a lot buddy.

Real good speakers, got them in my lancer. You really dont feel the need of installing an amp/woofer after hearing these. Had the 938 in my accent and those were Bad, nothing close to these. i Got them for around 4k with bill and warranty here in Mumbai. Hope this helps.

These are very capable speakers but there is no difference(technically speaking) between the 948 and 947. They are the same. If you want to buy them try listening to both before buying. There isn't much of a difference.

[blueraven316]

the 948 is old wine in a new bottle, I cannot differentiate a lot between the 938 / 948 / 947 etc, powerful speaker Don't know how the 400Watts equates to 100 RMS, cos the 938 is also 100 RMS and is 300 WAtts.
JBL's most popular speaker line GTO, next year we need a real upgrade, not some 958 or 949....

I dont think even Sam "the JBL guy" Kapasi (also known as The Yeti) can control that.

@Sathee46:
OT: Are you going in for an ICE upgrade, what does the ??? mean in your signature.
What are the options being considered?

Monsieur Andy Wehmeiyer sure could.

On this topic, I have to say that I'm not too pleased with the direction JBL is headed.
For eg. Toyota used to build the Supra, the celica, etc. And now we have Prius, Corolla, Camry. And the new Honda "sports car" CRZ is a hybrid.
