Another question about vented enclosure
I can't seem to get a good response (peaking @ about 32 hz) with the recommended sized box. The only thing I can see working is about 3.5 cu ft at the smallest, tuned to 24 hz. Again, I'm installing these in a car and looking for lows and good sq while I'm at it. I think 7 cu ft total is bigger than I want to go with it, but it's all I see working with the response. Any help?
This is why a sealed enclosure is recommended for SQ and lows from this woofer. 3.5 cubic feet will work although the port would have to be 14.5" H x 1" W x 16" D for a tune that low and you will run into port noise problems with anything over 500 watts. If you increased the port width to 2" to combat port noise the length would increase to 48" to get the same tuning frequency.

I would like to install 2 of these drivers in my 04 Legacy hatchback. I'm looking for good sq and lows. I have been thinking about 3.5 cu ft per sub, because I have one in the recommended 64 liter box right now, and it is clearly too small, and Winisd predicts something better in a larger box. My question is, would 7 cu ft total with 2 slot ports 2 x 14 inches have a good response in a vehicle, or would that be too big?
I would recommend skipping a vented enclosure for these altogether especially if you want SQ. I would recommend 1 cubic foot per woofer sealed.

best layout for max performance
Hi,What the best layout size, if I using with Dayton Audio SPA500 500W Subwoofer Plate Amplifier?With the woofer down to 20db.With a sealed enclouse.if possible can email the layout or link?
The amp you have chosen is great. To determine the best box - search on the internet for a "speaker box calculator" and plug in the specs. For a sealed box - use .707 for the total Qts. It will then tell you the box size and show you a response graph and predict the -3db down point - which is usually flat in a real room.

Down Firing for h.t?
Like to know is it good for down firing option?What size of dimension suit?Which amp will max the performance?Newbie for DIY.thanks
Wire the driver for a 4 ohm load, and make sure you have an amp that delivers 500 watts into 4 ohms. As for downfiring - that works best with sealed boxes. When ported, the driver can end up sagging over time. In choosing a cabinet - plug in the specs into an online speaker box calculator. It will show you response curves in real time. If sealed -- use .707 for the total Qts for flat response. It will then tell you the cabinet size and the F3, or the -3db down point for bass response. Keep in mind this is a number used for acoustic reference. In a real room, the woofer should be flat to this number, maybe lower dependning on driver placement... You will also see ported options. Do some reading and research before making your decision.

What would the ideal dimensions be for using this sub in a sealed enclosure for Home Theater subwoofer?
I have the Dayton Audio 240W amplifier to go with it.
The ideal internal dimensions would be a 14" cube. This is roughly 1.5 cubic feet which will allow the sub to handle low end and high power movie passages without issue.

What is the smallest cabinet size ?
Realistically, what is the smallest cabinet size you can put this into, assuming it is sealed (not ported) ? I have a 18"x14"x11" for my 12" Peerless and it sounds good. Can this work in a similar sized cabinet ?
Each driver has its own T/S parameters. They must be matched with the correct cabinet or they will not deliver the specified frequency response. If you look at the SPEAKER BUILDING TAB and then WOOFER SELECTION GUIDE - you can sort by SEALED VOLUME CU FT to find a woofer that matches the cabinet you have. As for the Epic - sealed it requires .79 cubic feet for a -3db (F3) of 53 hz. That's not subwoofer performance. The Epic performs better in a ported cabinet - but it must bee 2.26 cu ft and then goes down to 30hz.

best HT enclosure size ?
i want loud SPL and high SQ , for music and movies , or trade off more towards SQ , i have a nice amp just need a good sounding sub. i have a room size of 20ft x 14 ft roof is 9ft high any input would be appreciated
This speaker requires a inner space of 3.22 cubic feet. Build your box around that space and the speaker will sound fine.

has anyone used this sub for a home theater?
i dont know much about choosing subs for certain purposes, but the vmax and frequency response of this sub made me wonder id it would be a good choice for home theater purposes. if its not, what would be an ideal 12" sub for HT? i was looking for something around 500w rms.
It can be used for a home theater setup. There are a few things to consider. The first being the amplifier to drive this subwoofer.Most home theater receivers are not going to be able to drive this subwoofer because of the ohm rating and the wattage.The next part is designing an enclosure that is tuned to get the best sound. A standard box from your local Best Buy is probably not going to cut it. Most people are having good results constructing a 2'-2 1/2' cubic foot box. Or you could get the Dayton SWC2-BK enclosure (Or one similar). This enclosure will need to have the hole cut for the amplifier and the subwoofer.For amplifiers, I would check out Parts Express Bash 500 amplifier. The amplifier would power the subwoofer at the 500 watts needed at a 4ohm load and it has a crossover for fine tuning. (The subwoofer will need to be wired in a series configuration to match the 4 ohm load.)If your looking for an easier route you could use the Dayton Audio SPA500 Subwoofer Amplifier and the Dayton Audio SWC-2CO box that has the cutouts already done for you.

Hi, The SPL is given as 86.6 dB, is this measuerd at 2.83V or at 1W?
I am trying to work out whether the lower powered Peerless 830500 is a good substitute seems this TC sub is out of stock. I am concerned that the 150W peerless might not have the power handling capability.
THE MANUAL STATES THAT THE SPL IS @1WATT ABSORBED.

4.25 Cubic foot?
I just purchased the epic 12 and the 500w bash. I am trying to decide on the enclosure volume I should use. I was thing of using a 4.25cf enclosure tuned to 24hz. My only concern is this may be too large. I would appreciate any advice.
Nope, it models quite good in that size enclosure and handles 500 watts with no problem. The bash has a high pass around 20hz (not quite sure the exact number) which should also keep the driver under control below tuning.

Will this work in a folded horn enclosure?
I have plans for a THT from Bill Fitzsimmons and was wondering if this speaker would work.
Hi, I would ask Bill himself. He has a very active forum. His name is Bill Fitzmaurice and the website is: http://www.billfitzmaurice.com/

How would the epic 12 sound with planet audio 2400.1
I'm wanting to run one of these in my crew cab truck with a pa2400.1 amp. But I'm not sure how well it would do. I have about 3 cubic foot to work with. But if I can get away with less that would be better.
The amp will work just fine. Technically it is well more power than you need, but I would rather have the headroom to work with.Considering the application, my best suggestion would be a 4th order band pass enclosure. This way you optimize power handling and will likely get better output into the cab of the truck. the numbers that look best in my sims were a rear (sealed chamber) of 1 cu ft and a front chamber of 1.5 cu ft with a 4" port 13.5" long. You could also do a square port 15" wide x 1" tall 13.75" long or something in the same range and get the same output.If you don't want to build something that complex, I recommend a sealed box around 1.5 cubic feet which would give best results if you did two subs.

Best enclosure ?
I've been thinking of upgrading to a tc 12" epic .As of nowI am running a kicker 12" comp in a 2 cu ft ported Fiberglasbox. Running at 4 ohms on 135 watts Rms measured with DMM.With this little kicker I'm hitting 110 db.What type box would be better suited for TC epic 12 a ported or a sealed ? What cu ft range from small to large. And if ported howmany cu in for the port ? This would be installed in a car. My music preffrances are classic rock, rock, pop,and rap. I do like my bass more on the heavy side. Thanks.
THE TC HAS SEVERAL OPTIONS FIRST THE TYPE OF VEHICLE. THE CABINET SHOULD MATCH THE ACOUSTICS OF THE AUTO. WELL DAMPED, EXERCISE MAT AND HOT MELT ,ETC! THEN A FOLDED HORN WITH 2 SLOTTED VENTS COULD BREAK WINDOWS WITH THE RIGHT AMP, TRY THE CABINET THE KICKER WAS IN SEAL THE PORTS AND LISTEN AND FEEL THE SUBSONIC S YOU ARE LOOKING FOR !! THE PORT TUNING WILL NOT BE SIMILAR, CHECK THE T/S SPECS DO THE MATH AND SORTA COMPARE THEM! A 4TH ORDER DUAL CHAMBER WOULD HIT THE HARDEST , MOST COST EFFECTIVE BUT THE MATH AND BOX PORT DESIGN ARE NOT EASY ...PE /TC SOUND CAN GIVE YOU SPECS FOR SUCH A CABINET , I THINK A PASSIVE RADIATOR FOR CAR WITH 12 OR 15 IN PASSIVE WOULD BE BAD IDEA. THE CLEARANCE T3 SOUND 12 IN WHITE CONE WOULD BE SWEET TO TRY. I ALSO THINK YOU NEED MORE POWER A FARED OR SO TO.

will this suit
will this driver work in an open baffle speaker design along with the tang and WB 1808 full range driver
With almost one inch of xmax, yes, this speaker could be used in an open baffle alignment. The W8-1808 is a popular and well-reviewed driver, in my opinion the two would be quite good together. As with anything audio, your opinion may vary considerably, and there really is no right or wrong answer outside what sounds good to you individually.

What size sealed cab?
Will this work well in your 2cu ft cab sealed? Thanks!
Yes this woofer will work very well in either the 2 or 3 cubic foot sealed cabinets. For music, I would recommend the 2, movies and home theater I would recommend the 3.

Is the TC Sounds Epic 12 much improvement over the Titanic MKlll
or should I use a Titanic 15" MK lll in a vented sonotube
The TC Sounds Epic 12" isn't really much different than the Titanic MKIII series. The main difference between the two is that the Epic has two voice coils which allow for different wiring schemes.The Titanic 15" subwoofer would play lower and provide more output but does require a much larger enclosure (especially vented). Hope that helps!

How well would the TC Sounds Epic 12" work as a car sub?
I am trying to find a good single 12" to go in my car and don't have the money for what it would take to power the TC Sounds LMS-R 12".Also how would box size compare to the LMS-R?
I've used it in a 1 cu.ft. sealed enclosure for both home theater (EQ'd) and car audio. Use about a pound of polyester fill in the box. It was awesome in the car. Deep, smooth, flat frequency response. Fast hard hitting bass, buy it.
