Z-5500 Crossover Adjustment/Hacking

[Uninvited Guest]

Since I'd like to put full range speakers on my Z-5500 system, one of the problems that has been mentioned is the Z-550's built in crossover frequency of 120 ~ 150Hz. Because I don't fancy my sub playing my midrange, I was curious if there was any means to alter the crossover frequency- by whatever means possible.

I've tried googling it, but had little success. Perhaps my google kung fu is weak, but most of the results ended with people asking questions similar to mine with no replies.

Obviously through software would be ideal, but somehow I don't see this working. I connect to the Z-5500 receiver with the 6CH direct setup.

I'm not opposed to warranty voiding modifications- soldering, firmware flashing, etc. However, I'm no coder, so if anything involves hex editing/whatnot it has to either be really simple, or have super step by step instructions.

Much thanks.

I did some googling on this at one point too and came up with nothing. The conclusion I came to was that it just isn't a possibility. Software can't work as the signal, no matter how its tweaked, has to go through the Logitech amp which is ultimately going to dictate that 1x0Hz and under go to the subwoofer.

The question is could you hardware modify the unit by removing the crossover circuitry that's in there and replacing it, and I haven't found anyone that's done that.

err no. that thing can't drive full range anything.

The passive crossover is 150hz and unless you know what you're doing the best you can pull off is bass-redirect and accept a frequency hole in the 100-150hz region as a tradeoff for no midbass leaking into the frequencies.

Btw the midrange is about ~ 3KHz - 8KHz, I doubt the sub is audible at all at those frequencies 😛
