Did you try a different source, ie Ipod with 3.5mm to RCA cable?

Put the speakers on baffles, your probably getting some cancellation not having the rear wave isolated from the front.

Your port can't be 14" H if your box is 14" H then.

lol. that would be sick. have a spl sub and a somewhat sq sub. i wonder how it would sound.

Are you doing a slot port?

Spamming it up to sell something.

Yep. I guess market research shows more people add an amp for a subwoofer then for their front speakers. Which is stupid because you can still use the front full range output for sub duty. Are you sure it is only sub frequencies or is it just a non fading output.

Weird they would only put sub out rca's. Every one I've seen with single rcas is a front output.

What head unit is it?

Aaron, newegg has a special on Sennheiser HD 428 for 48 hours. 44.99 with promo code EMCYTZT745. http://www.newegg.com/Product/Product.aspx?Item=N82E16826106295&nm_mc=EMC-EXPRESS091011&cm_mmc=EMC-EXPRESS091011-_-EMC-091011-Index-_-index-_-26106295

Id go with one of each.

He did not have his sub wired at 4 ohms. He shorted one coil and was only using the other coil to power the sub.

I wouldnt suggest using this one, the area to the left of the port could act as "dead" area. Meaning the sub wont use it and you'd have a box way different then you originally calculated.

The gap for a d2 is the universal option, so yes he can.

You can tune a sealed system by using different enclosure volumes. Using the same sub each volume will have a different Fc and F3.

Hard to suggest an amp without knowing what coils you have on the sub.

IA will be having their black and blue sale real soon

Even white boys got to shout.... BABY GOT BACK!

How did you calculate for the multiple aero ports? It all comes down to port area. If you input more then one aeroport, the area of each port is added together, then port length is found for that total port area. Example: 10" circle = 78.54in^2 area. 2 10" circles = 157.08in^2 area. Same as: 1"x78.54" slot port, or 2"x157.04" slot port. That's wrong. You need to divide the box volume by number of ports and use that number and the area of one port. Also not accounting for flares, I wouldn't call it an aero port calculator then.

If you want to keep them the same you can use the SAX 125.2 http://www.soundsolu...%252d125.2.html
