Parts Express 80 Hz Low Pass 8 Ohm Crossover is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from awesome !hi I am very pleased with the crossovers and I had to lower the bass in my receiver. but now I probably need stronger subs for my 12 inch technics because it seams they can't take the power.

Rated 5 out of 5 by from Installed in Logitech Z5500 subwooferMy Logitech Z5500 system (yes I know, I am no audiophile, but it works) has been going strong for 10+ years but the sub's output has gotten muddy for whatever reason. This x-over really sharpened it up and it now produces a lot tighter, more accurate bass than it did new. Super easy to install and super inexpensive on top of that.

Rated 5 out of 5 by from in-line to active-sub...alot of bass and sounds coming from sub which is rated @ 150hz...read some reviews...bought the band-pass 80hz 8ohms...now i get deep/detailed bass...no more extra noises/sounds clean...system now performs THX certified like its supposed to, especially during movies...music sounds great/i don't need to turn my amp up all the way to 20, it now satisfies me @ 5...

Rated 5 out of 5 by from Good Low Pass passive crossoverNothing complicated. Installed in an old set of Peavey T-300 Model 1210TS PA Speakers on the 12" woofer. Clear bass sound. Big improvement. Assembly came out less expensive than buying parts separately.

Rated 5 out of 5 by from Performs to expectationsI bought the low pass filter to enable the low bass function on a pair of Gallo Reference 3.1 speakers. The filter functioned as expected and handled high wattage without appreciable heat. It is large and bulky, but it has to be in order to function properly.

Rated 5 out of 5 by from Optimus Pro 12 Subwoofer low pass modThe pair of 80 Hz Low Pass Filters i purchased here to upgrade the performance of my Optimus Pro 12 subwoofer have proven to be an exceptional improvement, overall;adding rich detailed bass to the sound without getting in the way of the soundfield from my Spica TC 50 or JBL 4301B speakers. A separate power amp is recommended to power the converted sub for best results. I use a classic Conrad Johnson tube amp to power my sattelites and needed a solution to improve the bass from the Optimus Pro 12 sub. If you have this sub and a separate power amp to run it , get these 80Hz Low Pass Filters for this sub and you'll soon be hearing a much better soundfield from whichever sattelite speakers you are using with better bass definition overall.

Parts Express 80 Hz Low Pass 8 Ohm Crossover

I have a pair of towers that have a 1" dome tweeter, dual 6.5 mids, and a 8" down-firing woofer.  The stock crossover is 800/3500 hz phase coherent.  Can i substitute this crossover and wire it to my sub so i just get lower sub frequencies?

I replaced a passive woofer with an active unit in some 3 way towers. It sounds great with extra bass however I want to add a xover to the second woofer so voice is not playing by the floor. Can I add a xover even though the towers have a 3 way xover

If I use this crossover with a 4 ohm subwoofer, can I assume the crossover point would change to 40z?  And would the slope remain 12db/oct?

Asked by: EddieR
yes, The crossover point would "half" in a low pass.

if I need this to handle more power, can I wire 2 of these in series, between the amplifier and an 8 ohm subwoofer? If wiring it this way is acceptable, what version of this crossover (4ohm or 8ohm) will be compatible with my 8ohm subwoofer?

Asked by: jcfogerty
Wiring two of these will change the crossover frequency. If you want higher powered crossovers you will have to swap the components on these boards with higher powered options.

I have drivers rated at 4 ohms impedance. Can this crossover be modified to function properly with this impedance rather than the 8 ohms design parameter?

Asked by: AES577
In order for this to work at the same frequency with a 4 ohm load the component values will have to both be changed. You would be farther ahead buying the 4 ohm version of this filter which you can see below.http://www.parts-express.com/parts-express-80-hz-low-pass-4-ohm-crossover--266-440

ok,got the answer!.so I Am Looking For A 500 Watt Version of this Trying to do this right!!. can you tell me were I may find one?.

Asked by: DJ BobbyT
We do not have any higher powered low pass filters at this frequency available. We do have a couple at 250 Hz that handle about 600 watts, but those are the only options we have.
