They work just fine, they are a simple capacitor...you should actually be able to find them cheaper. For door speakers I would cut them off near 125Hz or so

um u can go down to circuit city or best buy and nab them for like $7 or at least thats how much they are when i bought some like a year ago

THey do work, but have a very low (3db per octave) roll-off. What this means is that they let a lot of lower frequencies through. Most amps use a 12 or 18 db per octave roll off. I ran a set of 200 hz ones on my dash speakers in my old truck. Worked good, but they aren't the greatest crossovers (stopped my 4x6's from buzzing on bass hits though).

You can also get them at radio shack for like 99cents a piece.

I have some sitting in my room actually haha. I ran em till i got my equalizer. I'd let em go super cheap if you wanted.

Here is a blurb from Crutchfield's bass blocker page:

For smaller speakers (3-1/2"s, 4"x6"s, 4"s), the 600 Hz Bass Blockers work well with low-powered systems, while the 800 Hz Blockers are a better choice for high-power applications.

Speaker Size Cut-off Frequency

6-1/2", 5"x7"/6"x8" — 150 Hz
5", 5-1/4" — 300 Hz
3-1/2", 4", 4"x6" — 600 Hz (low power)
3-1/2", 4", 4"x6" — 800 Hz (high power)

I needed a pair for my Rockford Fosgate dash speakers, so I took the info that I needed to two different Radio Shacks. The first one looked but couldn't find anything like I needed and the second one sighed and said they used to sell stuff like that but don't anymore. ~get with it RS!~
I ended up buying on Ebay for $11.49 including shipping from this guy:

The 600 Hz blockers work great. They do exactly what I wanted them to do.
Just make sure you know what cut-off frequency you want before you buy!

You lose a lot of mid range cutting at 600Hz even if the rolloff slope is 3dB

SMNW2003, what would you suggest as a good cut-off point for 4X6?

150Hz or so with a 12 dB slope, mostly personal preference and where the subs are set
