498 sq inches does not equal .288 cu ft wrong again....there are not 1728 sq in one cubic foot. go with around 8 cu ft net for the solo...they love big boxes. The solo 12 would be in a 3-4 cu ft enclosure

no here as made a clear answer. When talking about enclosure volumes its either gross volume or net volume. Total volume does not specify anything. Net volume is the only volume of air the speaker "sees"...after all displacements Gross is the volume of everything inside the enclosure...driver, port, bracing, etc.

People use PA speakers with FS in the 40s and 50s all day for HT sub duties down to 20Hz. I would go ahead and try out a 40Hz t-line...if it doesn't play low enough than start adding stuffing. The enclosure should not be that hard to design if you have sketch up. Start with a long trapezoid with the ends the throat and terminus...throat is the bigger end and terminus the smaller. Then start folding it. Or you can just design a stepped taper which is easier

Actually it is plenty of power area...these subs are not high excursion subwoofers nor is the power application high at all. 24 sq inch of port area is basically two 4" round ports...plenty for a couple 10 inch subwoofers. The 12-14 sq in per cube is just a general guideline...mostly it depends on the size of the enclosure, sub specs, and applied power...doesn't have to follow the general guideline. There will be no problem with 24 sq in of port area

Have you ever owned 15L7s??

synonymous

for HT I would go with a tapered line starting between 120-150% sd and tapering down to 75-100% sd

wrong...a transmission line does not HAVE to have a 1:1 ratio for the effective line length

transmission lines do have volume. And there can be a chamber...its called a chambered t-line. People have been building them for years and years. The line ratio can be anything you want...depends on the specs of the driver. the 1:1 ratio is just the "general" basic start.

any enclosure implementing a port is ported. most people think of bass reflex when the word "ported" is used. As ported is very general.

well you need to figure what tuning frequency you want first. I would recommend four 4" round pipes. sticking the ports in a 4.5 cu ft gross enclosure will make the net volume not 4.5 cu ft

Look like an ass...apparently you have no idea what a ported enclosure is. I quoted the dumb fuck on craigslist you tard. How about you read my post again instead of you looking like an ass on here. I know about enclosures and feel no need to back that up. If you knew about 4th order bandpass enclosures you would know that they are not always louder than ported. The bandwith a bandpass will play is dependent on the enclosure. It can have a wide bandwith or narrow. Its all about the design. I'd suggest you stop looking like the ass here. Pwn

I would not go 3.5 cu ft. Too small. I have a 95 camry 2 door. A 4.5 cu ft enclosure will fit

your 10s can be louder in a BETTER enclosure. Also saying its loud turning the volume up to 8 usually means your gain is turned up too high

Enclosure is the difference "built to factory specs" means nothing

lol "Louder than ported"...bitch the box is a ported enclosure...dumb fuck

not even enough to port

Everyone over on ROE has already informed you that the 18 will not work in that small of space for a 4th order. As for the chamber sizes and tuning. That is ALL dependent upon the application. You can go for a low efficiency design with a wide bandwith or a highly efficient design with a very narrow bandwith. Design, build, test

solder connections on the box terminal look like cold solder joints to me

Passive radiator is just another form of a port...and your statement about the cones moving in opposition is false.

there is absolutely nothing wrong with running one coil on a DVC sub

designed a 4.3 cu ft tuned to 38Hz box for those...slammed hard down to below 30Hz easily.

flaring will help a little but a 4" round port would be much better...But fitting the length needed you would have to go with external ports

RE Calculator is not spot on accurate...but it is close enough for some people.
