KU40 sent you a pm, didnt want to thread jack.

Me and you are basically in the same boat, Im trying to make that decision myself between 2-12"s and 1-15". Ive never had a 15" sub before and want one but dont want that to be my reason for buying one. Like they say more cone area + more motor force = louder in some cases but what happens when you get a monster 15" does that same equation still hold. Hopefully we can get this answered together.

I dont know the answer to this but wanna take a shot, I know more experienced and knowledgeable people in this field will chime in. I think its because it takes more power to make lets say a 20 or 30Hz to get as loud as 60Hz. So if you set it at 20Hz when your reaching full output at that frequency level, then you will probably be throwing to much power to the sub when it its a 60Hz tone or start clipping the amp. IMO but I may be wrong, Im waiting to see what the answer to this is.

The amp will do better since its made for subwoofer type applications, a voltmetere is a device that will measure you voltage so you can tell if your having electrical problems. Yeah batcap 800s are good, I owned one before on less than 1600 watts and it did fine, no light dimming or big voltage drops. Make sure you re-do your big 3 wiring also to 4 gauge or better.

I was thinking a single 15" in 4 cubes. Do they make preamp subsonic filters? Just curious. Yeah actually they do make preamp sub sonic filters.

Thank you for the response. However, I am aware of the port length application. * Lower power handling noted The problem lies in the conundrum wherein the port length to obtain a super low tuning (20-25 hertz) is long enough to force my plans to increase the enclosure size to compensate for this length, unless I lessen the planned port width. That leads to a subsequent question. Relatively speaking, would decreasing a slot port width from 3 inches to 2 inches be inadequate for a 15" driver? Please do not go below 27Hz for Port Tuning and that depends on what subs you will use. Port width can be as wide as you want but you want to stay within the recommend port area (12-16in^2 per cube of internal volume), but 2 inches may be a little too narrow. How bout this list your goals and what you want from your next ported enclsosure and we can go from there. Cool. My goals are, in order of highest to lowest priority: Sound quality, low frequency response, SPL I'm curious as to why tuning should be 27 hertz or above. If I went with a slightly higher tuning, it would work, as my rockford p1000.1bd has the subsonic filter at 28 hertz if I turn it on. I'm not going to ask the redundant question of ported vs. sealed. It appears ported is recommended moreso. Anyway, I plan to use a single 15" driver, whether, Icon, FI Q, or SSD. Depending on money I may go with IDmax, but most likely not. Well the Q wants tuning 28Hz and above, Icon wants tuning 27Hz and above and the SSD wants tuning at 33Hz. So tuning below 27Hz wouldnt help you anyway since the company's dont even recommend that low tuning, then your box will kinda become a one hit wonder and music usually doesnt go that low unless you listen to a lot of chopped and screwed music or cd made by a pipe organ. With that set sonic filter you want to tune above 28hz, if you tune below it then the feature will be useless. mm, not so fast. Lowering box tuning will not make the setup a one note wonder. Raising the frequency will, not lowering it. Lowering tuning frequency expands the frequency response range of the driver and makes it more flat. The lower the tuning frequency is, the more the ported box behaves like a sealed box. I'm not sure how you got the findings that say that any of those drivers "want" a tuning frequency above what you listed. We could plug any of those subs into a HT application with the tuning frequency at 15 hz and they would be brilliant. Well I was speaking in a car environment they would want a lower tuning, know Im a little bit confused. I remember when we had this discussion about my ported enclosure I had for my CVX's tuned to 26Hz, everyone was telling me it was a waste and why tune it so low. I know that a sub could be put in a Home Theater application and shine, but for a car whats the lowest tuning that should be used or is there if any. Everyone was saying its absurd, blah blah blah and now you say its fine.

More info and read noob posting guidelines before posting again. hey faget im not a noob i no my shit i was just asking to see what everyones opinion was I love people who think there tough over the internet, what did you just accomplish nothing (you just let your emotions get the best of you, a females trait). Regardless if you know your so called shit your still a noob on this forum, now read the rules and repost that simple. And obviously you dont know your shit with that question up there, what subwoofers have good spiders and magnet.

I need to get at you about those batteries, could you pm me how much for 2 shipped to 76011 (brand new)?

To me its still useless, plus its only 65AH that sucks, group 34 battteries have around the same AH and their 12v batteries (so why get a battery made for another purpose to replace a battery that does the same thing for the purpose of what you need it for). Its one of those why bother questions, but if you want to get them because someone else runs them and is selling them then go ahead and be my guest.

Yeah no problem at all.

Everything plays into affect, but you missed what I said music does not trypically go that low so you wont be gaining anything from tuning that low (you will be losing a lot of output). It is a waste of a box and equipment because it wont benefit anything. Either sub will do and get the job done, whichever you buy you will be happy with.

First of all what amp are you running and any other equipment info that affects this? A wire melting is a good sign of over-voltage or the wire just isn't thick enough to handle the power going through it.

Haha, yeah you went to far, naw just playing. But I been wondering the same thing, not exactly worded how you put it but that design has me thinking.

I would go sub and port forward.

Lets get this show rolling and good luck man.

Lets get this build going, coming along nicely product rise.

I vote yes for the Christmas build, looks .

Actually those Seleniums 6.5" snd 8" are more mid-range speakers than mid-bass, they do sound nice and get loud but Eminence Alpha's are better (have experience with both of them).

That amp will do fine, eventually you may want to get a one channel amp that does around 800-1000rms @ 1 ohm. I would ditch the cap and by a voltmeter (if you run into dimming problems or low voltage then you will need to buy a extra battery or bigger stock battery), you should be fine.

Nice looking box man, when is this box going to get built?

I doubt it, havent heard of it or seen anything from them on this forum.

So people like you who have questions can get the right answer instead of just throwing some BS out there. Its easy man just follow the rules and make your life and everyone else's that much more easy. Thats a personal problem and something you need to work on, never let your emotions get the best of you (that's a females trait).

Why buy something if your not going to use it for its purpose, thats ridiculous. If your not going to change to a 16 or 17v setup then dont waste your money, buy only what you need.
