Help: Considering Subs for Tuned and Ported box that needs a very small box similiar

wouldn't frequencies lower than 50 be better overall for lower bass? like 40 or so?

Well if you filter it too low then you will be missing out on most of the bass notes actually.. Generally 80 hz is a good place to start. That means it can play everything from 80 hz and below including the low frequencies. You don't really wanna set it to 50 unless your fronts can play down that low. The dayton HO's love the high notes as well the lows so don't limit it with such a narrow range.

yeah i'd like to know a whole lot more about the crossover slopes, frequencies and such. Having the mids stop at a certain freq while the tweets and subs pickup at a certain freq or whatever the languo is //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

in a nutshell if you want to break it down to me feel free //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yeah called the tech and the bandpass xover has an on/off

Edit:

in a nutshell if you want to break it down to me feel free

on correction, it doesn't have an On/Off for the bandpass xover but here is what the tech emailed me:

There is no on off switch for the filter, to run for subs only all you would have to do is turn the lowpass knob all the way down, and the subsonic all the way down too. Then just set your low pass at the head unit around 80hz

That's great news, now you can just do everything through your headunit.

I could go on for days about tuning but to put it simply, there's really not that many choices to choose from on your headunit. When I look at your manual on page 66, it says the HPF is -12 db/octave slope and the sub slope is -18db/oct slope. There are no other choices on slope, but you can choose the frequency cut off though. They are definitely a good start for people getting into this hobby though. You get the most control out of your speakers when you use a Digital Signal Processor (DSP) or a better headunit with active capabilities. I would suggest to keep it simple and work with what you got before you dive into a new can of worms. Work on making your speakers sound the best they can before you even introduce the sub. Are you running stock speakers or going to get new ones? Either way you're gonna have to integrate the speakers and sub to a place where their frequencies meet. Your goal is to not have any huge gaps between the crossovers. I would start with hearing how low your mids can handle without distorting and/or rattling. Hopefully they can handle as low as 80 hz, that way you can just set your sub at 80 as well and call it a day. You can either have the xovers overlapping or underlapping. Up to you. If you feel it's too much or too little in that place, you can always EQ it to your taste.

here's a nice little article on understanding crossovers

will check out that link when I get time tomorrow.

going with Polk audio db 6501s for the front and going to take the kenwood 6x8's out of front door and put in rear deck
