I'm selling a brand new Clarion EQS746 7-band graphic equalizer/crossover. I purchased it to try to band-aid a small issue with my system, but realized that it wasn't going to cut it. The unit has been tested, but never installed. It still has the plastic protector sheet on the top. MSRP is $149.99, and I'm asking $90 I don't have a pic of mine cuz my camera's dead, but here's a pic from Clarion's website: Here's info from clarion's website 7-Band Graphic Equalizer 6-Channel / 7 Volt RCA Outputs (Front/Rear/Subwoofer) Adjustable Master Volume Level Control Adjustable Subwoofer Level Control 2-Channel RCA AUX Input with Adjustable Gain Selectable 12dB Low-Pass Crossover (60Hz or 90Hz) Gold Plated Terminals Dimensions:7"(W) × 1"(H) × 4"(D)
i will inform my friend. he has been looking (or having me look) for a EQ so he can chop the mid range out of his subs. i am kinda curious if cutting mid will help alot, he claims it will and he took audio engineering classes. but the mids dotn really bother me. hmm.... anyway i will tell him tommorow about it.
Ding Ding Ding..... Subs should never see over 100Hz, I have mine crossed over at ~90Hz (and I would like to go to 80, but I have other issues). Any higher than 100 and you will start to get massive "boomy-ness" and the sound will become directional. Dynapar, your friend may want to retake that class...
Not always the case, depending on the drivers, processing, and intentions your x-over points can be set all over the place. (i.e. working with room modes, etc...) But yeah, 9 times out of 10, and in rather simple systems thats quite correct.
I have yet to see a true "subwoofer", used in a proper situation, that supplies freq above 100Hz. Anything higher would be a "woofer". But, no need to argue on the details....either way they should NEVER be producing mid-range.
I've routed up to about 150Hz throuh sub cabinets before, but it was for a very specific reason. We were trying to fight a really nasty node in the performance space that hit right around 130Hz, and covered a large audience area. It was from a room generated reflection that was causing a minor comb filter. We didn't have time for a full phase re-alignemnt, so opted for the bandaid fix. Took two of the sub cabinets and used them in a different location to try and fill the void. It worked ok, but was just a bandaid for a time based problem. Either way, apples and oranges. That was on an EV X-Array Line Array system/procs with a MIDAS H3000 console. A system worth well over $500,000 There are applications, just very rare, and probably never in car audio.
