PAC BB-5PR Pair of 3.5" Bass Blocker

No real drop in output, other then the bass distortion is gone. They are the bomb for small speakers that pop when pushing them, as they won't pop anymore and run with the rear drivers as they should.

was very skeptical about them at first but the reviews here made them seem worth a try and wow these things are excellent no more cracking from my 4in speakers just crystal clear sound i installed 4 of them in my 94 aerostar 2 for my dash 4in speakers n 2 for my lift gate would recommend to anyone with a system looking for clean treble if i could give more than 5 stars i would!!!!

Works perfect on my Fosgate 3 1/2" dash speakers. I kept blowing speakers when I got a new head unit and I didn't know why . I researched bass blockers and gave these a try . Worked like a charm and i am still able to use my blown distorted speaker because it filters out the bass frequency and all I hear now I clear highs. Saved me money on buying new speakers!!!

Kicker 3.5 DS speakers and this bass blocker work excellent. Swapped all 6 factory speakers with no amp in car and having this bass blocker is critical. Was easy to splice and connect to Metra wire harness for Dodge Challenger. I hope it stands the test of time. Also using this bass blocker takes up more space to a cramped front dash speaker area so make sure you connect the wires well.

Not an audiophile so IDK. I was told I needed these for my 3.5" dash speakers. I added a crimp male spade to one end of this, and a crimp female spade to the other end. This enabled me to quickly and easily plug this "inline" on the positive side of the speaker. Inexpensive and easy to install so why not I guess? Their little logo sticker does not adhere well at all, one had fallen off already in the pack.

The base blockers are great quality and good price.

Added these to some 3.5” speakers I installed to replace my 07 FJ dash speakers. Works great and speakers sound clean and crisp. 3.5” speakers are useless for bass and will sound like a paper bag popping over and over again. These bass blockers solve that issue and make my 3.5” infinity reference speakers sound amazing. Mids and Highs come in loud and clear.

These have come a long way! i bought a pair roughly 20 years ago and they would cause the music to cut on and off at high volumes. Not the case. Installed on a set of Hertz 3.5s with an alpine mini amp feeding it 45watts RMS and they sound amazing. Nothing but mids and highs with great sound quality!

No more crackling sound coming from full range speakers! works great combined with a separate sub to replace what's now missing.

me sorprendió, sinceramente, hice el remplazo de los filtros, pasivos de 7khz +-12dbe unos tweeters Pioneer ts-t110, cuyo rango de frecuencia es de 2.5khz a 30khz, como experimento, con el fin de hacerlos de amplío rango y en conjunto tienen una respuesta excelente, se logró el objetivo y a pesar que las parlantes son de agencia, se logra subir y complementar el escenario.

Ok

este articulo facilita mucho las cosas pues no tienes que buscar tu las resistencias, pac tiene las versiones para cada tipo de bocina con las frecuencias correctas, sin duda un gran producto.

100% ok
