Eliminate bass distortion in your speakers

Eliminate bass distortion in your speakers

Protect your new car speakers from bass distortion and enjoy cleaner sound with Crutchfield's Bass Blockers. Each Bass Blocker handles up to 50 watts RMS with a 6 dB per octave roll-off. Here are some general guidelines for matching Bass Blockers to speaker size.

Speaker Size Cut-off Frequency

6-1/2", 5"x7"/6"x8" — 150 Hz

5-1/4" — 300 Hz

3-1/2", 4", 4"x6" — 600 Hz

These models come fitted with easy-to-use quick-slide connectors that make installation a cinch — no splicing or crimping needed.

The listed cut-off points are at 4 ohms. If you use 8-ohm speakers, the cut-off point is half the listed frequency. If you use 2-ohm speakers, the cut-off point is double the listed frequency.

Note: You can connect these Bass Blockers in either direction, as the built-in capacitors are not polarized.

Product Research

Features

Bass Blockers: Bass Blockers stop speaker distortion caused by excessive bass relative to a speaker's bass output capability. They are especially useful with small diameter speakers and tweeters.

Crossover Point: The crossover point changes based on the speaker impedance.

Model 2 ohms 4 ohms 8 ohms
007BB150 300 Hz 150 Hz 75 Hz
007BB300 600 Hz 300 Hz 150 Hz
007BB600 1,200 Hz 600 Hz 300 Hz
007BB5000 10,000 Hz 5,000 Hz 2,500 Hz

Easy Installation: To install the Bass Blockers, slip the female connectors of the bass blocker onto the positive and negative speaker terminals of the new speaker, and plug the male connectors into the speaker wiring adapter harness' positive and negative leads. If you don't want to use the terminals, cut them off, cut the speaker lead at a convenient location close to the speaker, then splice the Bass Blocker into the positive and negative speaker leads and insulate the connections. Bass blockers are not directional, so the orientation of the Bass Blockers on the positive and negative speaker leads is not important. Polarity is important; the white wire is positive and the black wire is negative.

I bought bass blockers because I do not want to ruin my new speakers with too much bass. [ MIKE  Dec 26, 2018 ]
A
I bought two sets of these to be used in parallel on the separate mids/highs in the doors. This will set the cut-off at 75Hz (one = 150Hz, two in parallel = 75Hz @ 4-ohms (per channel)) and above so as to limit the low-bass distortion of the mids. The subwoofer will do all the work below 75Hz anyway. The reduced bass extension of the mids will lower excursion distortion and improve midrange clarity at higher levels. [ Paul  Dec 04, 2018 ]

A
Using these for some 3.5" speakers up on my dash. The speakers have a frequency response down to 80Hz, but no reason to have them reproduce notes that low.

I got these for my 77 Chrysler. The stock AM/FM radio puts out too much bass on the AM side. AM radio, especially talk radio, is all mid-range anyway. The bass adds nothing.

3-1/2" Infinity Reference dash speakers sound incredible but distort low midrange at higher volume (windows down, music up!). Bought the 600Hz cut off as the crossover on the headunit (Pioneer 4100NEX) handles both the dash and front door speakers.

I need to block 80hz and below for my kicker ks series 6x9's. Which bass blocker do I need?
[ Dustin  Feb 26, 2019 ]

A
Well crutchfield only has down to 150hz on blockers. If your set on 80 hz. Google 80hz bass blockers. Theirs 1 that is 80 hz. Parts express.
[ David Cook  Mar 01, 2019 ]
A
Maybe go higher than the 150's. I bought 2 pair however, after I put them in my front 6.5's I noticed that they didn't have any real effect so I never installed them in the rear.

Hi, Dustin 6X9 is a good speaker and will handle good wattage, don't understand why do you want to use the speaker as a woofer.

Q
Can I install these on 3 way kicker 6x9's?
[ Aaron  Apr 03, 2018 ]
4 answers
A
You can, but the 6x9s should be able to handle bass down to 60hz or so. I wouldn't use bass blockers on those unless you have something else to handle the lower frequencies. I use these on my dash speakers (3.5 inch) and let my 6x9s in the rear handle the bass.
[ Jeffery D.  Apr 04, 2018 ]
A
yes you can install them inline with a 3 way 6x9. However, if you do this, you will be limiting the performance of the mid and low range portion of the speaker. In most speaker set ups the bass blocker is used only in line with the tweeter, to limit the low range frequency from blowing the tweeter. Most Speakers designed for multiple ranges have individual limits in place for each of the ranges they cover. My suggestion would be to look at the specifications of the speakers you are looking at purchasing. Find out if they have built in limiters. If not, consider running a two way mid and low with a satellite tweeter.
[ mark  Apr 03, 2018 ]
A
Yes. But you wouldn't want to. It'll block all your bass and a lot of the midrange. I installed these on some little 3 inch full range dash speakers to get rid of the bass and such. They act like a kinda upper mid to high tweeter. With that being said. No, don't install them on 3 way speakers. Unless you wanna take 70% of your speakers capability away.
[ JAMES  Apr 03, 2018 ]
A
Of course
[ Phillip  Apr 03, 2018 ]
Q
I didnt word my first question right. If i had bass blockers hooked up to a car speaker would i be able to tap into the same speaker and still get the line output converter to play bass for my aftermarket sub?
[ Jonte  Jan 26, 2018 ]
1 answer
A
It would be recommended to use a different speaker-level signal to your aftermarket sub/amp than the speakers you have connected to bass blockers. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

Q
I am going to get the Kicker 44KSC3504 in the dash and the doors are going to be 44KSC6504. Do I need these and what frequencies?
[ jared  Jan 26, 2018 ]
1 answer
A
Yes, if your dash and door speakers don't have a crossover. I used factory wiring so my dash speakers were getting the same signal as my door speakers. Installing the 150hz blockers made a positive difference in qualit of sound. I'm very glad I took this step.
[ Drew  Jan 31, 2018 ]
Q
Can you use these with a line output converter hooked up to subwoofers?
[ Jonte  Jan 17, 2018 ]
4 answers
A
I don't think they are designed for use with a "line level" signal, They will cut the low end "< 150Hz" to an amplified signal. I use them to protect my smaller dash speakers from frequencies below their ability.
[ Brian  Jan 23, 2018 ]
A
you could but they block the bass frequency, so if you are hooked up to subwoofer then you will only get the high frequencies. not what you want for a sub.

I can't see why not but why would you want to block low frequencies to a speaker designed for low frequencies? Btw, crutchfield has excellent support, give them a call and they'll get you set up right.

You can use these with any signal. However, be cautious to the speaker you are directing them to as they will affect the output. For example a 150hz bass blocker on a subwoofer would be pointless. But, if you use it for a 6.5" coaxial it would make sense. The point is to minimize low frequency extremes on smaller speakers to maximize output.

Q
If my front tweeters are wired with my 2 Front Door Speakers, do I need to purchase another set for the front speakers and connect the set I already bought to the tweeter wires before they merge with the door speaker wiring?

A
These bass blockers should only be connected to your door speakers. They are not appropriate for protecting your tweeters from low frequencies. If your tweeters are factory equipment they should already have a passive crossover in place, so you only need the one set of bass blockers. If you have aftermarket tweeters you should use the supplied crossovers that came with the aftermarket tweeters and connect them to the door speakers.

Q
I have 2 speakers that are 4" but run at 8ohms. The other 2 are 4x6s and run at 4ohms. I see that these are rated at 600hz at 4ohms. What do you suggest I use for the speakers running at 8ohms?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss the compatible options. They will be able to determine if everything will integrate and help you make the best decision for your system and your budget.
