Dayton Audio DCS450-4 18" Classic Subwoofer 4 Ohm
Sealed enclosure specs anyone? HT and Music Duty Use...
I am thinking of purchasing this driver for an HT sub, but kind of worried I won't get much low freq extension if going with a smallish sealed configuration... Does anyone know or have experience in placing this in a sealed enclosure? I am wanting to stay in the 3-3.5cu ft range if at all possible and it will be for 50/50 HT/music duty. If not I suppose I will go with a 15" I am working with a 350w rms plate amp at 4ohms. Thanks in advance.
Actually the software sims show the driver working superbly in a 3 to 3.5 cu ft sealed enclosure. There is a very small rise around 65 hz which, when combined with typical room gains should make for a very good in room response with an f3 around 35 to 40 hz. For HT it may fall off just a little higher than I would like, but not badly. If it were me, I would make the enclosure either down firing or corner loaded if possible to take advantage of loading the room and extending the low response into the 20s while keeping the sealed response and power handling. Should work great!

Good sub for live sound?
I would like to know if this would be a good subwoofer for live sound applications. I am thinking about putting two of these in a 5.0cf box and porting them but I am wondering if they would project large amounts of sound at pretty high levels. I need to know if they are durable enough to withstand long periods of heavy use and if they will really provide the sound reinforcement I need.
This Dayton Audio 18" speaker has design characteristics good for either sealed or vented enclosures. Power handling is 300 watts. Your question is a little difficult to answer because I don't know what you require from your sub.If you desire big kick drum, bass axe and wish to cover mid to large venues with one 18" sub, then noway. A small venue a little kick punch and bass assist it will help out a lot. Getting good smooth solid sub low end requires moving a lot of air. This means the more cone area and the more power the more you get.How much do you desire? This is a great speaker for the cost and would be a good replacement for many branded boxes .

What will be louder when ported this 18 or a Dayton titanic 15?
I just want most SPL for the buck
In the appropriate enclosure for each speaker, the Classic 18" will be just slightly louder than the Titanic 15". The difference is less than 2db @ 77Hz (where the SPLs are closest).

Anyone have plans for a 4th order bandpass
I am wondering if anyone out there has built a 4th order bandpass for this sub and if so if they could share measurements.
Hi KA 4th order box will give you a very narrow bandwidth.In this case will be arround 23 - 62 Hz with a substancial loss of power.The ref point will be - 3dB.Anyway, the volume of the chambers will be 229 liters for the rear and 126 for the front chamber with 1 vent 4" dia 2.5 inches long. The resonance frequency will be arround 37.3 HzI strongly recommend a well braced system, glue and screws, It will rattle a lot if the cabinet is not very sturdy. If you choose plywood, try to find BALTIC BIRCH first quality. Dont use construccion grade. Is not perfect inside rattling "inside" the wood.And cheap baltic birch is only good on the outside.BestDavid

Is this sub good for an IB application?
Absolutely yes.In an IB arrangement Qts is equal to Qtc. Qtc is an expression of how compliant a system is, (how "flat" the response curve would be,) When you design a speaker with a Qtc of 0.707 it is considered "optimal". Lower and the curve rolls off sooner, but at a slower rate. Higher and the curve gets sharper around the driver's Fs.at 0.47 the Qts of this driver is still high enough to keep the cone under control, but low enough that it will likely roll off at nearly the same rate as your room gains start to push on. A higher Qts speaker would get louder but in a smaller range of frequencies.Use multiples, four of these have the same surface area as eight 15" drivers. Surface area is the real defining factor in making bass, smaller drivers use increased Xmax to make up the difference and these monsters have respectable Xmax anyways. This driver will be louder than even a Titanic 15" because it has the surface area of two 15" drivers no matter how far they move.

would this driver work well in a car/suv?
i have a suv where the size of the box dose not matter and was thinking of purchasing two of these drivers and was wondering if these subs could put out some serous spl close 150 db
.yes, if you put it in the right box and have room it would sound great. Lots of thump .
