Doing a simple factory door speaker upgrade on my 2017 ford focus titanium. Using 2 sxe 1750S components. They dont come with a passive crossover so i got these as a cheap and simple solution to cut out any midbass frequencies to my tweeters [ Atrayou  Jun 11, 2019 ]

A
the toyota sequoia 2003-2007 with JBL premium system has separate wire sets driving front front tweeters ,mids and woofers. when bypassing factory amp (in my case using a new component amp and eq/line driver) these will cut any unnecessary lower frequency's that would otherwise diminish sound quality. great thing is i didn't have to search for them because crutchfield has done the research for you and automatically is an available option with the components i chose. gotta love this company .

I have some older stock tweeters that share a signal with the stock woofers. I'm replacing the woofers but not the tweeters (for various reasons) but the bass blockers will help them keep sound quality at higher volumes. [ Stuart  Nov 25, 2017 ]
A
Because Paul, my cust. service rep. suggested them for what I was trying to do. Paul had A LOT of patents with me. I wanted to try and save my factory speakers from the Aftermarket headunit I am putting in. He let me know that what I need to do is replace my speakers (for the best), but I did not want to do that yet and I know I would not be able to afford nor pick out the speakers I would want yet. [ Jim  Oct 30, 2017 ]
A
As I'm a novice, I purchased these to help protect my tweeters against low frequencies. [ Bobby  Oct 18, 2017 ]
A
Previous 1 inch tweeters I used had bass blocker at 2800hz. Current smaller 3/4 inch tweeters recommend 4500-5000hz cut off, so decided to try these. [ John  Oct 15, 2017 ]
A
i need them [ Victor  Sep 29, 2017 ]

Q
Should I put these between a component speaker and its crossover or would they even be necessary?
[ Chandler  Oct 05, 2019 ]

A
It depends, some components come with their own, or built in... I used them to hookup factory tweeters when I swap the door speakers and removed proprietary electronics which probably had a hpf...
[ David  Oct 06, 2019 ]
A
Your crossover will handle the mids between the speaker and the tweeters, you would need them on lets say a front deck set, since those normally would be inline with your door speakers.
[ Joseph  Oct 05, 2019 ]
Q
What would the frequency cut off be on a 2 ohm (metered at 2.5 ohm) JBL tweeter?
[ Charles  Jun 11, 2018 ]
1 answer
A
If you use 2-ohm tweeters, the cut-off point doubles; making it 10,000 Hz instead of 5,000. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
