100 Hz Low Pass 4 Ohm Crossover

Convenient crossovers that work great in any application requiring economical and flexible filtering. Also for use in car stereo installations with component speaker systems. Low pass, band pass, and high pass models complement woofers, midranges, and tweeters. Designed to be wired in-line between amp and speaker by using .205" disconnect terminals or soldering. The crossovers' compact size facilitates mounting virtually anywhere you desire.

Specifications: • Approximately 250 watts RMS • Type: Low pass • Driver impedance: 4 ohm • Crossover frequency: 100 Hz • Roll off: 12 dB.

100 Hz Low Pass 4 Ohm Crossover
100 Hz Low Pass 4 Ohm Crossover is rated 4.2857 out of 5 by 7.
Rated 5 out of 5 by from Nicely builtI am using this for a subwoofer project (see pics). I bought a powered JVC 10" sub box for $5 at a pawn shop. I ripped the guts out, and added a Dayton Audio SD270A-88 DVC 10" woofer. For my set-up I found that there was too many high freqs coming through. So, I bought two of these low pass filters. They work like a charm! 100Hz is perfect and nailed it the first time. Seriously smooth. The JVC box's structure is too weak for this woofer and the baffle inside for the filters came loose (it rattles at high volume). Right now that is being fixed with Gorilla glue and wood screws.PROS: The filters are WELL built, strong, and heavyCONS: The 4 mounting holes on the ends had to be drilled out to accept wood mounting screws. Needs some type of harness.

Rated 5 out of 5 by from Does exactly what I want it to do.I crossed over a 6.5" sub and now it is relatively quieter (as expected) but the bass hits harder and lower.It's really just a barebones crossover but it's all that most people should really need. If you want a higher quality or more specific crossover, just build it yourself.

Rated 5 out of 5 by from Works Great With My Subwoofer and 2-channel Amp!I have a two-channel amp, Kicker ZX200.4 to boost the power to my rear speakers. I really needed more bass so I bought a passive subwoofer Bazooka Tube for the trunk and my only option to install it was in Bridged Mode on the amp. This low pass crossover works Awesome! It sits in-line between the Amp and subwoofer and now my audio system sounds Wonderful! What a difference the subwoofer makes. Sounds almost as good as my home system! Kicker recommended a four channel amp to drive the subwoofer, but that was another $175 so I decided to try this crossover.

Rated 2 out of 5 by from It will cause interference on other speakersIt will cause interference on other speakers, it dos filters highs. It will send interference to receiver and spreads through out all speakers.

Rated 4 out of 5 by from OEM PerformanceMy Def Tech 300w low pass amps went south. D/T said woofers crossed @ 100hz/4ohm. Installed these, bypassing the amps. Wow! Cleaner/tighter bottom end. Now they are "clean & green". Those active speaks use a lot of juice. I let the NAD 2700 do what it's supposed to do, everything.

100 Hz Low Pass 4 Ohm Crossover

Impedance of crossover

What is the Impendance of this crossover that will be added to the amplifier?
Asked by: Shelso
This should have a 9mH inductor which if these use the 18 awg I core sould be 0.56 ohms.On a side note if this does indeed use the same 18 AWG I core inductor as part 266-578 it is cheaper to buy these then the inductor by itself, but that makes me question if these do use the 18 awg inductors.

for a dvc (2+2ohm)...

if i combine both 2ohm coils on a sub to run a 4ohm load from amp, do i still need two of this, one for each coil, or can i use the 2ohm coils wired together/4ohm with a single one of these low pass filters?
Asked by: m.oreilly
If you wired the coils in series for a 4 ohm load you only need to use one low pass filter between the subwoofer and amplifier.

Two drivers using Hp & Lp ?

Building my first project speaker.I'm going to use a 15" Boston Acoustic subwoofer and a Goldwood GW-10PC-4 10".What i want to know is, if i'm using a 100hz Low pass Filter for the 15" and a 100Hz high pass filter for the 10", will my impedance will stay a 4ohm because i'm using filter ? Or it will drop a 2ohms ?Thanks
Asked by: Sebthesoundmaster
It will stay at 4 ohms but may drop to 3-3.5 around the crossover point. This is fairly typical, if you have an amplifier that handles a 4 ohm load this will not be a problem.

What type of 2nd Order Crossover?

Is it Linkwitz-Riley, Bessel, Butterworth, or Chebychev?
Asked by: Alan
This (and all our pre-made crossovers, unless otherwise stated) is a 2nd order Linkwitz-Riley configuration.

Will this work with 2 8 ohm subs wired in parallel?

Asked by: Noisegoon
Sure will. Two 8 ohm subs wired in parallel gives a 4 ohm load.

Will wiring a 4 ohm crossover to a 4 ohm speaker reduce overall ohm load to 2 ohms

Asked by: QuadFather
No, crossovers are designed for specific loads, 4 ohm, 8ohm, 16ohm, etc... if designed correctly the impact on final impedance of the speaker should be minimal.Since the effect of the capacitive and inductive reactance depend on the load impedance different values of both capacitors and inductors must be used for speakers of different impedance values.To achieve the same crossover frequency on a 4 ohm load as an 8 ohm load you must half the inductance and double the capacitance. The opposite is true for a 16 ohm load vs. an 8 ohm load.
