About the JBL Stadium GTO750T

Stadium highs

JBL's Stadium GTO750T tweeters help bring new dimension to your music, thanks to an edge-driven PEI polymer dome that enhances sound dispersion and delivers natural-sounding highs. Super-compact inline crossovers send the appropriate frequencies to these tweeters, making them just a little bit easier to install.

Stadium highs

JBL's Stadium GTO750T tweeters help bring new dimension to your music, thanks to an edge-driven PEI polymer dome that enhances sound dispersion and delivers natural-sounding highs. Super-compact inline crossovers send the appropriate frequencies to these tweeters, making them just a little bit easier to install.

Awesome power-handling

These tweeters can handle up to 50 watts RMS, so you can add them to just about any system. Their 2.5-ohm impedance safely draws a little more power from your radio or amp, while their exceptional efficiency delivers strong volume and detail even with lower power.

Installation-ready

No matter how complicated your car's interior, JBL's versatile mounting hardware gives you plenty of options for flush- or surface-mounting these tweeters. Whether you're replacing burned-out tweeters or adding tweeters to brighten up a dull-sounding system, these JBLs will add detail and dimension to your music.

Installation note: You'll need a pair of our universal backstraps to install these tweeters in the factory locations.

I purchased these to replace the factory tweeters and enhance the treble since I have two 12" woofers in the back.

Pros: Great sound and excellent appearance! Match the factory tweeter pod grills perfectly.

Cons:

Purchased these to replace factory tweets. Sounds so much better than factory. Can hear the highs now, other factory speakers used to drown out factory tweets.

Nice tweeters

Purchased a set to add to my 2017 Toyota Tacoma with factory JBL system. I wired them to the existing dash speakers and surface mounted in the door sail panels without using the included high pass filter. These integrate really well. Exactly what the factory system needed.

Pros: Very nice sound Good price with holiday sale

Cons:

Just what my 2009 Highlander JBL system needed

Gary from Austin, TX on 8/30/2018

2009 Toyota Highlander

Verified customer (What's this?)
Verified employee purchase (What's this?)

The JBL Stadium tweeters added what my 2009 Toyota Highlander JBL system missing. For some inexplicable reason, the JBL system in the Highlander only has midrange speakers in the dash and woofers in the front doors. The new Stadium tweeters fix the problem and them some. I used the enclosed crossovers for the tweeters and added an inductor coil in series with the midranges for an approximately 2000 Hz crossover to the tweeter. Even though the tweeters are 2.5 ohms and the midranges are 2.0 ohms impedance, the Stadium tweeters are more efficient than the midranges. They are somewhat bright in my setup. It would be nice if JBL included some kind of adjustment switch on the tweeter crossovers, say -1db, -2db or -3db, so as to better blend the tweeters with the rest of the system. I set my stereo receiver to -2 for the highs and it sounds good. Next, I plan to replace the awful 6-3/4" rear door speakers with JBL Stadium speakers. Please note, these tweeters were a challenge to install in the Highlander! They come with a surface mount housing, but I found that they stuck up to high for my liking, so I used the nicer looking mounts that required much more drilling and cutting.

Wrong Description

Frank from Dunn, NC on 8/7/2018

2010 Kia Soul

Verified customer (What's this?)
Verified employee purchase (What's this?)

There is a crucial error in the description for these tweeters. They are not soft dome at all but edge edge driven PEI material and the sound is harsh and shrill.

Pros: None

Cons: Not soft dome as described. Edge driven PEI material!

Features

Mounting: The edge-driven soft dome tweeters can be mounted several different ways using the included hardware:

  • I-Mount System: The tweeters can be surface- or flush-mounted with JBL's I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and inserted into the hole. The large plastic locking nut is threaded onto the housing (from behind the mounting surface) to hold the assembly securely in place. When flush mounted, the tweeters may be angled for optimum imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Bottom Mount: Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under 3/8 inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.
