New member Username: YinyangCA Post Number: 3 Registered: Oct-04 | Equipment used: Alpine CDA-9833 Infinity Kappa Perfect 6.1 and 5.1 Component Systems. No External Amp. I know nothing about how to use an EQ and Crossover. Do I need to adjust anything to the Alpine's EQ and Crossover? I don't think I would have to since I have premium components all around, but do I need to adjust the Alpine's Crossover at all? Won't the Perfect 6.1's and 5.1's external crossovers do all the adjustments for me? I'm a bit confused on what I should adjust. Please, help with any opinions. thanks in advance. |

New member Username: YinyangCA Post Number: 5 Registered: Oct-04 | ok, maybe I've got ppl. stumped about this question of mine. Let me try and make this simpler. Since my components already have external crossovers... do I NEED to make any crossover and or EQ adjustments to the Alpine CDA-9833? |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 5145 Registered: Dec-03 | set XO on the alpine to 100Hz high pass for both component sets with a slope of 12 or 18dB/octave. that'll prevent them from bottoming out. if you use subs, set LPF to 80Hz, 18dB slope. EQ settings are personal taste unless you have an RTA to set them for accuracy. |

New member Username: YinyangCA Post Number: 6 Registered: Oct-04 | The XO option menu on the alpine goes in this order for a 2-way setup: step 1: Desired parameter: LOW (Subwoofer) -> MID -> HIGH step 2: Adjustable frequency bands: 20Hz to 200Hz (in 1/3 octave steps)(adjustable for each parameter (LOW, Mid, High)) step 3: Adjustable slope: (adjustable for each parameter (Low, Mid, High)) 0 (Flat (OFF)), 1 (6 dB/oct.), 2 (12 dB/oct.), 3 (18 dB/oct.), 4 (24 dB/oct.) step 4: Adjustable output level: -12 to 0 db (adjustable for each parameter (LOW, Mid, High)) My question is when I set the Mids to "0" (FLAT) why do I hear much more bass coming from the mid-range speakers and will it be better to set them at 24 dB/oct. rather than at 18 dB/oct. like you suggested? If you can provide better settings for all the functions above that I've just listed; please do so. I need the correct setup. I'm a newbie at this so thanks for your guidance and patients Glasswolf. P.s. what do you mean by "bottoming out"? |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 5165 Registered: Dec-03 | the shallower the slope, the more sound you'll hear below the crossover point. each octave is half of the previous frequency, and the dB setting is how much quieter the audio is each octave down. at 0, there is NO roll off. for midrange, 12dB is fine for roll off. subs, you want to roll up and off steeply to preserve the sharp bass, so its not boomy or muddy. use a steeper slope like 18dB for subs here's more on slope: http://www.bcae1.com/xovrslop.htm and EQs http://www.bcae1.com/elecxovr.htm bottoming out means the speaker is trying to produce frequencies lower than it can handle, so it just distorts instead of actually playing the notes. blocking lower frequencies from the speakers lets them play louder without distorting. |

Bronze Member Username: YinyangCA Post Number: 12 Registered: Oct-04 | GlassWolf, Here are my XO settings in the Alpine 9833 HU so far. 2-way XO setting: Lows -0 phase, 80Hz, 18 dB/oct Mids -0 phase, 100KHz, 12 dB/oct Highs -0 phase, 125Khz, 12 dB/oct Question: will it be safe if I set it up so that the Mids are 80Hz instead of 100Khz and the Highs at 100Khz instead of 125Khz without worrying about damaging anything? Appreciate the help. |

Unregistered guest | How do I know what the output level should be set on to send to an alpine amp for sub and amp for other speakers? |

swiftsword69 Unregistered guest | I've got a 9835. Heres my current settings, SUB W @ 80hz -2 12gb slope. Rear coaxial @ 100hz -2 12db slope and front components set @ 80hz -3 24db slope. I prefer a bit more punch from my 12 inch sealed box sub, but i dont want it to dominate the mid range. I would still like to hear detail from the mid range coming out of the speakers. Are my current settings ideal to achieve what i want? or any suggestions for changes?? Any help appreciated |

New member Username: FirlefanzPost Number: 2 Registered: Jul-05 | @JTran your first question was, if youd need to change settings in the HU when you do have external XOs. If you want to use the external then the answer is no. If you want to control the frequencies from the HU , you have to change the as in the post above. But you need to wire each speaker seperately. Depending on the quality of the XO's you should be better of using the HU. |
