I bought these to cut some bass out of the cheap 6x9s i accuqired from a friend, they worked great and cut out the distortion from the speakers. Its been six months now still going strong!
I had stock speakers and my headunit was over powering my 6x9s. I threw these in and ended up working pretty well.
I purchased this product in the process of creating a overall good sounding system. I have two 15 Kicker CVX subs powered by a Hifonics 1700, so needless to say I had plenty of bass, the speakers I had were getting distorted when loud. I picked up 2 pairs of these and it was a world of difference. Great overall product.
the easy install my(4) 6X9 sound great shipping was fast
Helps a lot!
These were perfect to cancel out some unwanted frequencies going to my alpine and Rockford Fosgate speakers. Now there is less chance of them getting damaged when I crank my tunes.
They stop the rattle!
Added these to my door speakers (Infinity Kappa 5x7s) since my Kappa sub does all the low end work - solved my door panel rattle. Does good job of rolling off beneath 300hz. Wish it was adjustable, but thats what a crossover is for.
Blocked the base to my tweaters in my 2002 Mustang with factory Mach speakers.
exactly what i needed
I called sonic electronix and told him what I needed... exactly what I needed and works great
Works great… for 4”x6”
Threw these in a order with 4x6 NVX speakers to get free shipping, they worked great in helping those little speakers keep up with the 6x9 NVX speakers I had installed previously. I don’t know why these are advertised for 6x9 when most car speakers are 4-ohm instead of 8-ohm, I could see a 6x9 needing to be cutoff at 150Hz but not 300Hz
So when I had first bought this I was worried knowing I had a inline converter to my back door speaker to my sub well not only did it stop alot off bass coming out of the door speakers it also made my bass sound more clear I was impressed what these little things can do
These worked wonders for my 4 6x8s hooked up to a 4 channel amp
