Product Research

Features

Inverted Dome Tweeter: The tweeter is an inverted aluminum and magnesium dome, producing a broad sound stage. The tweeter has a Neodymium magnet to provide a powerful magnetic field for the voice coil, while still maintaining the tweeter's compact dimensions.

Note: When flush mounted, the tweeters are pressure fit into the opening, with nothing holding them from behind, so the cutout diameter is very important.

Mounting Options: The tweeters include flush mount and angled surface mount housings:

  Flush Mount Angled Surface Mount
Mounting Height 0.312" 2.105"
Mounting Depth 0.658" 0.875" (screw depth)
Frame Diameter 1.957" N/A
Cutout Diameter 1.74" N/A
Width N/A 1.968"
Surface Depth N/A 3.114"

Crossovers: The included 19" tweeter wires have integrated crossovers. The tweeter ends of the wires have quick-slide terminals that easily connect to the wires soldered to the tweeters.

Customer Q&A

8 questions already asked

Q
what's the free air resonance in these tweeters?
[ Peterdemas25  Jul 07, 2020 ]
1 answer
A
From my understanding of free air resonance is you dont need to enclose these speakers to obtain optimum sound and performance. Where as your typical speaker requires an enclosure to try and get the fullness.of what that typical speaker has to offer. This is my opinion from personal experience.

Q
what's the resonant frequency in these?
[ Peterdemas25  Jul 07, 2020 ]

A
That is 2600Hz
[ Paul  Jul 19, 2020 ]  Staff

Not sure what you mean. They sound good very dynamic with a forward presentation. Give them a little bit of power and you won't be disappointed.

Q
what is the wire polarity on these??? i have a clear and a copper wire - NO LABELS!
[ craig  Apr 12, 2020 ]
1 answer
A
Should be a black line down one of the wires should indicate ground.
[ Jered  Apr 12, 2020 ]
Q
Are there matching woofers? The component sets from focal on this site don't seem to include horn tweeters
[ Henry  Feb 16, 2020 ]
2 answers
A
No woofers. These are tweeters only. Very happy with my purchase of these though. Plenty of clarity, nice low profile crossover and come with a couple different mounting options.
[ Jered  Feb 17, 2020 ]
A
The tweeters were the only size I could make fit in a sony woofer tweeter speaker system. I drilled out the old ones and glued these in. Not ideal but the car is a 1987 911 Targa and sound quality isn't that important since I can't hear much anyway. Seems to be working though.
[ John  Feb 17, 2020 ]
Q
I'll be wiring these in parallel with a full-range coaxial. does the inline crossover filter out highs from the coaxial? or would I end up with highs coming from both the coaxial and the tweeter?
[ hot ham water  Aug 30, 2018 ]
2 answers
A
nice! sorry for all the reply questions. do you have them wired in parallel with your door speakers? is the built-in crossover part of the wire or is it inside the tweeter? did your hummer already have tweeters that you replaced with these or did you add them? are your door speakers stock or after market? Thanks!
[ hot ham water  Aug 31, 2018 ]
A
I have had one too many train whistles blown in my ears, so I am not a sound expert in any sort of way. These speakers don't seem to cancel out the tweeters in my door speakers and sound much better than the stock speakers that came standard in my Hummer.
[ Thomas  Aug 31, 2018 ]
Q
Says they fit rear pillar of Toyota FJ, but don't list as a fit for dash (Similar Size). Can you confirm they would fit? More importantly do you supply mounting hardware, beyond wire plug?
[ Eusebio  Feb 22, 2018 ]
