The JBL GTO Series

The JBL GTO series speakers are the perfect upgrade to your existing speakers. They are designed with a carbon-injected cone material to accurately reproduce music the way the artist originally intended. The three ohm voice coils allow the speaker to operate at an efficient 4 ohms once they are being powered, allowing them to utilize every watt of power your head-unit or 4ohm stable amplifier can produce. These speakers feature a vented magnet with a high thermal-capable voice coil which effectively dissipates heat, ensuring the longevity of your investment. The edge-driven speaker cones allow greater sound levels with the same amount of power. The wide frequency responses that these speakers provide will leave your ears very satisfied when you're listening to your favorite songs. If quality is your goal, the GTO series speakers by JBL have the technologies to make that happen.



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.

Excellent Speaker

The following review is for a previous version (GTO428).

I bought these along with the 528's as re-placements for my MTC...Because they are 2 OHM they effectively double the power of my head unit which is stock....( and cannot be re-placed )....I have gone to full volume with these without them distorting , which I find amazing.

Exceeding my expectations

The following review is for a previous version (GTO428).

I dropped four of these into my 2009 328i - couldn't believe how bad the stock speakers were. Amazingly bad.

I have always been impressed with JBL speakers and thought at this
price, I would give them a try. Best $100 I have spent in a long time. I can even play the system at the maximum volume w/o any distortion. That is more a function of the head unit / amp, but either way I am sure the speakers will last a long time because of this compatibility.

I did have to get a little creative with mounting, but nothing I wouldn't do again.

JBL GTO Speakers

The following review is for a previous version (GTO428).

I own a 2010 BMW E90, great car but the BMW Professional sound system is awful, especially the rear deck 4 inch factory woofers (BMW bean counters took out all the tweeters and the amp on this car in 2010). One of my factory rears was crackling, and degrading the sound to the point where I couldn't stand listening. Rather than have BMW (under warranty) replace the poor factory speakers with new poor factory speakers, I selected the JBL's because they are 2 ohm (like my OE), and coaxial. They arrived fast, looked very well made, and installed easily (when I took out the OE, both sides had the magnet and voice coil separating from the plastic cage). The JBL's sound great, clear high's and mids (even though the head unit sends high pass signal only to rear). The whole car sounds "acceptable" now thanks to the rears being better. Cant wait to work on the fronts speakers next, but this fix gives me time to do it right.

Working Great

The following review is for a previous version (GTO428).

I got these because I needed some 2 ohm speakers to replace some broken bose speakers. They are working great. Sound better than the $440 bose replacements the audi dealer wanted me to buy. It would have been nice if they had made another 4 attachment tabs around the edges to better match my asymmetric audi door mounts but that's not realistic.

The following review is for a previous version (GTO428).

First JBL product I've personally used I was very satisfied with the clarity from such a small 4 inch speaker I would suggest buying these if your in the market for such a speaker

great speaker, great sound

This speaker rocks!! Installed them on my 2013 BMW K1600 GTL motorcycle, and the sound is vastly improved over the stock system. With only minor modifications they fit snugly in the original cut outs. I tried and blew the MTX 4 inchers and the Polk dbi 4 inchers. They have both high sensitivity power handling for their size. A can't miss!!
