Professional JBL Sound:

With the long history of professional audio equipment manufactured my JBL, it is no surprise that the Grand Touring Series (GTO) produce some of the finest sound available for car speakers. By integrating the majority of JBL's top car speaker technology, these speakers are able to effectively deliver truly stunning audio, while keeping the price affordable for everyone. For those that are looking for a quality car speaker that will not only sound great, but also keep more money in your pockets. Put your trust in JBL and these Grand Touring Series speakers.

Tweeter-Level Adjustment with Unipoint:

The tweeters on the GTO series speakers are an excellent example of JBL's advanced technology. Made from My/Ti (Mylar and Titanium composite), the tweeters offer a higher power handling, greater efficiency, and reduced distortion. To direct that sound where you want, JBL has designed a Unipoint rotating tweeter pod that allows the tweeter to be directed towards the listener. This results is better imaging and a more accurate sound stage. To top of the tweeter technology, JBL engineered a tweeter-level control switch that adjusts the tweeter dB output. This allows for more sound adjustments after the speaker is installed.




The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

review

The clearness of the voice in very good the bass is ok. Theses speakers are not really made for bass. Also, due to high bass the tweeter which is located on top of the cone, gets hit and makes a very nasty noise!!! I'm running a 4-channel amp with these speakers.

AWESOME HIGHS!

These speakers have the best tweeters of any speaker I have ever bought and I have had kicker, alpine, polk, RF, clarion, pioneer, and more. Such a clear crisp high it gave me goose bumps the first time a turned them up. I have a subwoofer so It doesn't rally mater to me but Bass is ok, About the same as my stock ford speakers but a little clearer. Fit right into my f250 door holes and the stock screw holes lined up to. After I listened to the pair I bought for the front I ordered two more for the back very happy.

Good mids; limited bass

Sound quality is good, but i was expecting more in the bass department. Important to note that i am not running an amp with these speakers.

Big sound for a small speaker

Listed as a 6 x 8 speakers, but they truly are a 5 x 7 that fits original mounts. These speakers provide great bass response, the built in cross-overs and the adjustable tweeters make directing your sound correctly a breeze. I use a aftermarket Alpine with a 45 watt amp with Infinity 5 x 7 front and these GTO-8628 in the rear. Sonic's price made these speakers a no brainer.

entry level

for the price i couldnt beat it. decent bass responsce, mids were alittle muddy at high volumes, as with highs. a good head unit and amp should fix that hopefully. overall im happy with them, but i would get the 4 0r 5 way pioneers if i had to order again. id say middle of the road and price point for most, not awsome, deffinatly not bad. wayy better than stock :)

Great Speakers

I have always liked JBL speakers since I built a home stereo years ago in the 80s. Great speaker for the car. Everyone that has heard my system likes there sound.

VERY accurate speakers for the price

these are very accurate speakers (as mentioned above)...
Woofer Review:
the bass response is tight...no distortion to speak of...at full volume with the bass i get punchy, tight sounds that really give the music more of home stereo feel (which is what i want)...the vocals are very strong and don't get distorted at high levels...

Tweeter Review:
The way that the tweeters are designed is very practical...on normal setups it seems that the crispy highs get driven right into my shins...to the point of not really noticing them..with these GTOs you can adjust the angle of the tweeter so that the sounds can be driven upwards towards the driver so the highs don't get lost in the bass....and the tweeters are really sweat...again no fuzz or distortion just crispy highs...

i have a amp on order for them, but really off of the head unit they are A1 components....I HIGHLY recommend these to budget shoppers and audiophiles alike...

Good Performance

Having had older model JBL GTO's, these have similar voicing.... good bottom end with deep kick, neutral midrange, but the poly/ titanium tweeters need taming a bit. This was without attenuating the tweeters via the switch so that's still an option. I left it as is since they were installed in the upper doors off-axis (Ford Mountaineer) and just pivoted the tweeter angles to point more towards the dome light. The upper frequencies on the EQ were gently sloped down until they sounded more natural. The bottom end was cut off using a hpf of 100hz @ -12db. They can handle going a bit lower to fullrange, but sound cleaner with that particular xover point while still having more than enough upper bass to blend with a small sub.

Powered by a 65x4 US Acoustic amp, they handle power well and don't reach breakup until the deck is turned up to max at which that point, they're LOUD! Mated with an Infinity 860W bridged on the same amp's rear, this was a great match. The overall sound is very good for a deck with limited EQ & Xover, no time alignment.

These are more than worth the purchase if you're on a tight budget. The adjustability is about as close as you can get to having a component set.
