The sales person told me I should buy them after hearing what Focal speakers I had bought. But the tweeters already come with them so I did not need them.

Pros: Price

I purchased kicker tweeters and they came with speaker wire with capacitors. Wired in vehicle and tweeters started to buzz and crackle at higher volume. So I purchased these as a replacement and they work excellent!! I now have really great highs!

Pros: Easy to wire into existing speaker wire.

Cons: None thus far.

Used these to keep factory tweeters as they were wired in with the door woofers during speaker upgrade.

Pros: Easy to connect

Cons: Had to look up wire colors on internet. My door speaker wires were different colors than head unit. But also not hard to find.

Crutchfield customer from Torrance, CA on 4/18/2019

Verified employee purchase (What's this?)

Solid bass blockers for your tweeters. Crutchfield makes it really easy for installing these in any stereo setup with the black and white wires. I shortened the wires leading my tweeters to get the unit as close to them as possible and attached them via spade connectors so that they could be removed if needed without cutting wires. These units cut the bass going to my tweeters really well and resolved the clipping noise I was getting at higher volumes. You will need to tune your EQ to get the most out of your system once these are installed.

Pros: Quality construction and easy install

Cons: NA

30hz rolloff its not.

randall from Louisville, KY on 5/18/2018

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

This was to take the rumble out of a brand-new transport rig (IH) -monsoon- which had a bunch of non-livable rumble on SOME FM signals. Clearly this is the wrong item. I thought I was buying a 30hz bass-cut 12db filter. It might have worked. The factor that we seem to have found here is BREAK IN, and the nasty rumbling that I had encountered is becoming less and less. I wish they had this device marked 30hz; the way search seems to think it had found.

Pros: nice poly bag.

Cons: not usable in my system.

Needs install guidance

Peter from North Canton, OH on 4/29/2018

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

These work but I have an issue with install. My understanding is that these are directional (and phone tech verified this as accurate). That is, the input and output side does make a difference. They do not come with male/female ends to help guide that directional connection. There was no marking on the filters. Tech was not sure how to figure out either. I had others from Crutchfield and looked at all the online pics to see which side the input and output wires entered and exited. I hope I have connected correctly...they seem to work well (crystal highs). But they should come with directions or guidance on this. It would suck to put hundreds of dollars into speakers then waste in due to an inexpensive part with bad instructions. This is not typical of Crutchfield's usually great products and services. But it should be clarified. If they are not uni-directional, the phone tech should know that or instructions should say "hook up in any ole direction."

Pros: works as it should affordable

Cons: no directional/install guidance

Crutchfield response on 5/2/2018
Thanks to Peter's review, we're updating our online presentation for the Crutchfield Bass Blockers. Our Tech Support guru, AJ, pointed out that the capacitor in these Bass Blockers aren't polarized, so they are not directional. You can connect them in either direction. We'll update our training for our Advisors as well.

Bassblockers work fine

Eric from Dothan, AL on 12/22/2017

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

Bought these to install in on some after market tweeters that would normally use a crossover for the woofer and tweeter combines. The tweeter location is in the A pillar of 2012 Ford f150 making it a nightmare to try and run wires for through the door jamb. I dumped the aftermarket crossover and used these instead for the tweeter and it works perfectly. Way easier than messing with running wires.

Pros: Capacitors are configured for a tweeter install so you don't have to guess the size needed. It does as it should and blocks the low frequencies.

Cons: Not really any cons.

Bought to Help Factory Tweeters

Stuart from Mankato, MN on 12/10/2017

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

I have a 2004 Volvo S80 with stock tweeters that had started to crackle a bit at high volumes. They were wired in parallel with the front door woofers with no crossover, so I bought a pair of these to block the low signals that the 6 other stock speaker can handle just fine. They no longer have a crackle when the volume goes higher, so they do their job! For $10, they are an excellent quick upgrade for a factory tweeter's performance.

Pros: Simple, nothing fancy. Cut the lines, solder these in the middle, and you're golden.

Cons: None, they do their job and that's that.

Bass blockers

Justin from COLORADO on 10/23/2017

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

I recently installed these inline bass blockers on my tweeters and they seem to work really well the clarity of the sound has improved greatly since these were installed

Pros: They are really easy to install and our relatively small. I just wired them in and tape them to the door so they wouldn't rattle

Cons: I was thinking about adding some amp power to the speakers I wish these bass blockers could handle higher RMS not sure if I'll run a amp now

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 .

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.

As I'm a novice, I purchased these to help protect my tweeters against low frequencies. [ Bobby  Oct 18, 2017 ]

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!
