Balanced out my 3 1/2s nicely

Balanced out my new JBL 3 1/2s nicely. Prior to adding the Bass Blockers, my new speakers were drawing too much bass from the factory head unit, causing distortion and the need to position the Fader almost 80% to the rear. Luke from Crutchfield helped me to pick the right Blockers for my setup, which includes 4 new Kickers 6x9s from Crutchfield that I installed about a month ago. Thanks again for the help and advice. The system is balanced now I'm my '23 Jeep WL

These do a great job limiting the low frequency from my 3 1/2 speakers in my dash. It has taken all the distortion out of the music and my system sound great now.

Only lasted a few years

Lasted maybe 2-3 years then they started cutting out. Finally got around to diagnosing why my front speakers weren't working, thought it was the head unit. Nope. both bass blockers crapped out.

Easy to use product that clearly work as advertised, although I ended up leaving them out (for now). The recommended 600 HZ ones for my 4" Focals was too much bass cut, at least until we add amp and sub which is on the list. Then they may go back in. Only giving four stars because I think the documentation around these could be better and suggest whether to use when doing only direct stock speaker replacement.

Simple install with new infinity speakers in dash. Very necessary to get a clean sound from a stock head unit. Upgraded the rear 4" speakers to the Kickers just for comparison. All sounds much better.

Changed the Overall Audio Experience

The 3.5 inch speakers on my FJ cruiser perform much better after installing the 300hz bass blocker. The same output is shared by the 6X9 door speakers and the 3.5 inches dashboard and I had to settle for low bass setup due to the distortion from the small speakers. After installing the bass blocker I can enjoy clear bass from the 6X9 without any distortion.

Worth every penny, Amazing results

OMG! I have a set of 6 1/2" 2 way bookshelf speakers in the garage with a 10" sub. They sounded fine at low volumes, but if you cranked it up the little 6 1/2" didn't like playing the very low base. They tried really hard but they are little. I added the Bass Blockers to them so they don't even try to play the low bass. The bookshelf speakers are 6 ohm, so they roll off around 110hz, the sub takes care of everything below 120 hz. Now when you crank it up, no more distortion from the bookshelf speakers. Pretty impressive change for the price!

Bass blockers really work. Almost too well

Work great. Block the bass. Maybe a little too much, but they still work. My system uses JL Audio XD600/6v2, I have the JL C2 3 1/2 in the front dash with the 150mhz blockers and they seemed to let just a little too much bass through so when I put more of the same speaker in the tailgate I went with the recommended 600mhz blockers. The 150mhz definitely sounded much fuller and louder, so maybe something in the middle would be better.

Bass blocker

These were recommended for my 3.5 kicker dash speakers. I was skeptical of how much this addition would enhance the sound but after installing I can say well worth the money and effort. The speakers had nice clarity before but felt like they were screaming. These bass blockers balanced the sound significantly. Would recommend for smaller speakers with bright tweeters.

Protects small speakers

Most people probably use these for tweeters, but I use them for the 4" Pioneer dash speakers I installed in my 2006 Scion xB. I used 300Hz blockers. Before I added the blockers, the little speakers were working too hard, vibrating the whole dash while trying to keep up with every bass note -- even just voices on the news or podcasts! The blockers were a cinch to install, and now the speakers give highs and mids in balance with the door speakers, without working too hard. I think 600Hz blockers would have been fine, too, but I appreciate having some extra mids in the front. Highly recommend to other first-gen xB owners!

Worth their weight in gold

These blockers are a must even if your speakers have built in crossovers. At least I've found that to be the case when installing mids of 88 sensitivity or less. They really smoothed out the rumbling caused by lower frequencies. That they are compact and affordable only sweetens the deal.

AVOID

Great for making your speakers not work. Wired these in with a factory head unit (2021 F150 Sync4) and RF 6.5" component speakers and was surprised to get nothing out. I verified the install (which is not complex), and found that speakers with these installed produced no sound. Removed them and the speakers worked. I'm not sure if there is a wattage cutoff or if there are signals that these don't get along with, but in my case they made an otherwise working speaker non-functional until removed. I have no idea if I got two consecutive duds or if the documentation is crummy, but my strong recommendation is that you test this before using or buying more than one. If I were using a crossover or had better control of the DSP on my factory head unit, I would say that's the better solution regardless.

I needed bass blockers for my center channel 3 1/2 " JBL Club speaker in my '16 Toyota Tundra DC. I am using my head unit amp to push it. My other speakers have their on amp and crossover set to 100hz, however I needed the bass blocker so my 3 1/2" center speaker wouldn't be over extended by low frequencies. It was the perfect solution and literally took me minutes to install. Now my system shines like it should.

Titan XD Pro4X center channel

I used the Crutchfield 600Hz Bass Blocker on the center channel speaker in my 2017 Nissan Titan XD Pro4X. I attached these to a Sony 3.5 inch midrange driver to keep the vocals from being muddies up by lower frequencies. I got exactly what I bargained for. The Crutchfield Bass Blocker met my expectations and kept the vocal clean and clear for the production of a wonderfully imaged sound stage without pesky distortion at higher volumes. The Bass Blocker were very easy to connect inline with the speaker. One note, the capacitor should be wired inline on the Positive terminal. I was a bit surprised that the product did not come with any installation instructions, or at least a simple wiring diagram. But, I YouTube'd it and was back in business in no time. Great product! I would certainly recommend to anyone looking to clean up the lower end of the frequency spectrum when using a driver not intended to reproduce bass.
