Welcome to SSA!

Stealth, I hope your home is enveloped by a volcano, you have proven time, and time again that your insight is generally false. Instead of flaming someone you need to be able to express why you think something over someone else belief.

How many times do I have to say this? Apparently the "All-knowing Stealth" can't wrap his head around this, you design the enclosure around the subwoofer, not the other way around. Enclosure size does not dictate port area, the parameters of the driver does.

I should add that there is supposed to be a processing update on the HTC, I'm not sure when though.

Why? Why "daily" systems should not count on impedance rise - SSA Car Audio Forum

Stealth, stop cluttering Brandon's thread with name calling. If you would like to point fingers and insult me do it in a private message. Brandon, use Jacobs recommendations as it is always best to listen to the manufacturer.

What stealth said is correct, but NEVER count in impedance rise in a daily system.

I wouldn't put 18's in that little space, two 15's would perform better as they would be in an optimal enclosure.

If you would like to stick with your list of woofers, the L7's would be your best choice.

Listing several drivers and saying each will be in the right enclosure wont help you at all. We need to know your goals, as there might be a woofer that isn't on your list better suited for your goals.

More designs to come!

X2. Did you know impedance changes when power is applied? Like when the voice coil heats up? It's called impedance rise.

It looks like total Mayhem!

The Eris runs on Android 1.6, and the Moto is 2.0. A much improved version,the moto had double the processing as well, when you compare the Moto runs circles around the HTC.

Oh my bad

Yup. Windows Mobile or Android, of the two Android 2.0 is far superior. Blackberry's are good too, they concentrate on business though.

Are you sure you need it? 99% of people don't need them.

We should use the exact xmax, yes.

With an EBP of 157, I don't know any program worth using that would suggest a sealed enclosure. If there is a program that suggests sealed w/ a Qts of .2 and an Fs of 34hz....stop using that program. Nick Morgan told me, I don't know which program gave those results either.

The Warden 21" is 59 lbs.

29in^2 per cube(for a 5ft^3 ported enclosure) seems like a lot even if you dont go by enclosure size. If I had the exact xmax it would be more accurate, I estimated it to be 27mm.

Making that recommendation doesn't tell him the exact minimum amount of port area needed to avoid port noise. so you are telling me that he will have port noise with 15-17 per and it will be audible???? are you a dumbass, or just a dumbass. my recommendation is not telling him the minimum amount or port area needed without port noise, its giving him a proper starting point for a daily system with lots of output. While it will reduce port noise your recommendation will make mechanical failure more likely. My estimation gives the OP the minimum amount of port area needed to reduce the likelihood of port noise as well as reduce the chances of mechanical failure. You recommending 15-17 proves your stupidity and your lack of understanding of enclosure design. Stop making recommendations as all of them have been proven incorrect.
