Will this work as a sub?

post #1 of 21

I already built some ported enclosures, and the bass is weak. I think it is the woofers. So will these provide enough subwoofer-like bass, or will i need a real sub like this?

I don't want to have to spend any more than necessary, so i would perfer the first one(I have to buy two).

Either one will work just fine. The actual subwoofer you linked hits as low as 30Hz, the other goes to 37Hz....both frequencies are lower than you'll ACTUALLY hear from an 8" driver though. I'd say its more than likely your box that's giving you the problems. Why not try a slightly bigger driver (10" or 12"), and use a sealed box? You can also use a car subwoofer as well...just make sure to match your resistance up properly. If you have a 4ohm stable amp, make sure to use a DVC 2ohm sub, or a SVC 4ohm sub.

just curious when your building the cabs are you doing any sort of modeling on them with taking their T/S parameters or just estimating on how things should go?

also as far as that first speaker it is more of a woofer rather then a sub. I don't believe you will get the performance you are looking for out of that. could be wrong though but I don't believe I am on this one.

for ported enclosures, there VERY small(when i built them, i didn't know about any of that, right now im not to sure either, anyway, the enclosures are 10" tall by 7" wide by 12" deep, and a 12" flared port 2"dia.)

as for being a woofer, my question is, will it get a heavy bass drum, which is what mine are lacking now.

the amp doesn't specify what resistance its for, but is says 120watt. I need 4ohm though for the crossover to work(if you could call it a crossover lol).

another note, the port seems to be tuned well enough, but i feel very little air coming out of the port.

Ported boxes need to be "tuned" to each specific subwoofer. It sounds to me like the box isn't tuned right. If you're not getting the sound you want, its more than likely either your driver (subwoofer), or the enclosure at fault. For a subwoofer, you typically want it to hit 25Hz or lower....8" drivers usually cannot do that. Either one you listed will sound almost the same. I only know sealed boxes because they are much easier to make.....and in my opinion they sound better if made properly. Like I said, I'd go for a slightly bigger sub (10" or 12"), and just go sealed with it. It'll be nice and responsive on almost all the tones you want it to hit.

that might of been part of your problem. speaker boxes need to be tuned for the specific speaker you building. you can take two 10" subs one might require a 1 1/2 cubic foot box the other might take a 3 cubic foot box and that is not counting the port length. also with ported boxes generally they need to be larger then a sealed box also generally. if you build the box and port length wrong you usually end up with either a one note wonder box or a box that just can't play any frequency that well.

take a look for a program by the name of winisd. it might help you a little bit.

I won't deny they are easier to make (Sealed box that is) but generally they don't go near as low as a ported unit or is their frequency response quite as flat or wide. But they do have their downsides. if built wrong they can sound like crap and also there are some phase, and group delay issues you get more with a ported box that you don't get with a sealed box.

it's all in how you build it and what drivers you use though as many ported systems can sound really good if built right.

I can agree with parts of what you're saying. However I've always used Pioneer subwoofers (go figure with my name), and I build them in sealed boxes slightly larger than what the manufacturer states (I figure in the size of the woofer as taking up space, so I add that into my measurements)....and they have ALWAYS hit below 30-25Hz depending on size (10" - 12" respectively), and they've very responsive all the way up to roughly 80Hz to 100Hz (12" and 10" respectively, roughly). Its all about the speaker AND the box. I know for a fact that Pioneer branded subwoofers SOUND best in a sealed box. And since that's all I've used, that's all I can personally recommend.

However I do know and understand ported boxes CAN sound right. But 99% of them usually are very frequency limited. They usually have roughly a 20Hz range they hit (like 40Hz to 60Hz), and that's about it. Ported boxes are a royal pain, and to somebody who may not have much experience in speaker building, I wouldn't want them to start out trying to build a ported (or heaven forbid a bandpass...4way or 6way). These are all reasons why I suggested a sealed.

And you are also correct in another way. Ported boxes ARE BIGGER period. For an 8", and this is just a guess, but I'd say you'd need probably at least a 1.75cu ft. box....and I have no clue about port lengths or whatnot. The ONLY ported box I've successfully made was a slot ported box with 4 feet of port behind it. That box was roughly 3cu. ft (guessing here) and it was just for a 10" Pioneer Premier subwoofer. The thing pounded louder than most 15's though. I can upload a rough image of it if you'd like...the box (however it'd be made in paint, and completely rough estimates).

ported boxes generally have quite a bit wider bandwidth then a sealed box IF they are built right. problem is generally they aren't as you said and end up being a one hit wonder. sure maybe great if all you are after is SPL and only play at that frequency range, but to tune them right does take more work and still then many are willing to give.

larger sealed boxes don't always mean lower frequency response either. it might flatten the frequency out a little bit but usually going for a larger box then what is required is also going to hurt efficiency. if you want to go deeper then ported would be more efficient.

as far as your sub being able to go to 25hz. I would almost doubt that it would do it on it's own. chances are you are experiencing two things. the first is some psychoaccoustics. the first being that with harmonics if you play the harmonics for 25hz even without having a 25hz tone you will still hear it as though it is playing at 25hz. the other thing is your car itself is giving gain to the lower end frequencies making it sound as though the sub is playing louder then what it is. cars are great for that . that is also what is leading me to a problem I have with my own older infinity perfect. designed for a car and as such designed for the room gain that a car has to those lower frequencies. in the car in a sealed box it sounds great. nice and loud and plays fairly deep but bring it in the house and it's low end goes away. or even worse play it outside and wow it has no low end at all.


one last thing I want to say though. I haven't heard many ported boxes that sound well. I myself would rather not build one if I don't have to, and for a more or new guy trying to build a box would say go sealed as well. it might be lacking in a few things but with how much easier they are to build and how much more leway you have to mess up it would be better. a messed up ported seems to sound worse then a screwed up sealed. and with sealed it is just that much harder to screw up anyway.

to the OP if you want hit up diyaudio.com this is something the guys over there do all the time. you should be able to get some good pointers and help picking out a sub.

I would have to agree partially. I have used test tones from Bass Mekaniks and myself as well, and in the car, my subs in a 1.75cu ft. sealed box (Pioneer Premier 2000SPL's), they go down to 20Hz successfully....listening to it, and watching it play from the trunk, and they go as low as roughly 5Hz watching them.

In the home however, the EXACT same setup hits the same viewing frequencies (obviously, the box hasn't changed any), and goes as low (hearing wise) as 25Hz. And in both cases, they go up to roughly 80Hz without changing MUCH in the levels. Once I pass about 70Hz, they start to fade out slightly, but after 80Hz they fade out very quickly. Every Pioneer subwoofer I've had has done this for me....they seem to have excellent response in sealed boxes.

Other subwoofers probably vary...okay, well I'm sure they vary. Now in the ported box I made for my single Pioneer Premier 10" sub, it hit as low as 30Hz successfully in the car, and about 35Hz in the home. I'll make an MSpaint picture to show you the basic design of it. Its just a rough guess though.

I know where you're coming from rx7speed, just understand I do know a little something about car audio as well . I may not know it all, but I do know how my own setups have performed. And in most of the enclosures I have personally used, the sealed was best 99% of the time...and had excellent response.

But that's just me...other people prefer other box types. Its just like computer cases, everyone has their own taste.

Okay, here's an EXTREMELY rough drawing of the design of that box. I could be off on the measurements, but you get the idea. The air had to move I believe it was 48" total length before it exited the box.
