To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
They got the job done. Will they save your Twitter for being blown due to bass, yes. But they do have a scratchiness to them. The factory crossover that killed my kicker which was smaller than these sounds much better but it died and I can't get them anywhere else so here we are. for the record I'm a audiophile though so my standards are higher than the average.
I took a chance on these bass blockers after my expensive Infinity Kappa tweeters blew up due to a bad installation by a professional installer. The Infinity tweeters came with their own cross-overs but they were not supposed to be wired into the cables of my co-axial Alpine door speakers. They did not last long due to the over-whelming bass impact and excessive power that they were not intended to handle. These bass blockers did the trick to prevent my cheaper replacement tweeters from blowing up the same way. They are also specific as to their power rating.
I was worried there wouldn't work well with my factory radio, but I was wrong! These caps work great and do not muffle or lower Volume at all, and only let the highest highs through. 5khz.
Do not hesitate to buy these if you are installing component speakers but don't want to drill the door panel to run wire for your crossover. This is the solution, just wire this inline positive with your factory full range signal and you'll be rocking!
Changed the tweeters in my car but they didn’t have crossovers built in like my previous set! So once I played music it was distorting bad because bass was being played through, now with these installed they sound like tweeters should! Worked perfect just put on the positive end and your done!
Extremely satisfied with the amount of bass it filters out of my new tweeters! I drive them with a 200 white receiver that was built in the 80s and the sound is amazing and I am extremely satisfied with these filters as they are doing exactly as they were advertised! Extremely easy to hook up and And I think the price is spot on.
Works Perfect! Very easy to install simply spice into the positive speaker wire. Some cars may have a limited space b/t the tweeters and the enclosure and this bass blocker may not fit. You may have to take the door panel off and splice into the wires there. Fortunately on the 2000 mustangs mach 460 system there is just enough space to squeeze everything together!
*edited: my wife drives a 2016 Mazda CX-5. Audio sucked. I put Polk tweeters in the vehicle and less than two years later both Polk bass blockers went bad. Replaced with these. These are excellent and are super easy to install!
Replaced a stock Polk teeter bass blocker that somehow went bad. The item worked perfectly. They are small and get the job done. They have nice length of wire on each end as well which made the job easy.
If you wanna block bass a have twitters for years but this. By the way they are good for horns and twitters multiple output just hook it up on the main line and no more replacing twitters after every gig. I keep ordering more and more.
These Blockers let all the volume through and no bass. I put these on a set of Kickers because the crossovers quit. The crossovers killed just a little bit (as they are made for full range amps) with these all the volume is there and crisp sound all the way. I would put these on the next set of Sept-rets hands down!
