Re: Building Custom Subwoofers!!!!

The 2000 would be enough for these subs but the 2500 could also be used for a future project. It's up to you.

Re: Building Custom Subwoofers!!!!

Procast - I saw another post of yours and wanted to clarify something.

An EP2500/4000 won't overpower or damage your subs (unless you run it at excessive levels). It'll have power in reserve and handle peaks well - but you actually want to overbuy wattage - rather than underbuy.

You're more likely to have clipping and higher levels of distortion - if you buy a small amp, and then power speakers that have a higher wattage than the amp (and run the small amp at high gain).

A higher wattage amp just means you adjust the gain lower to get the desired output.

Re: Building Custom Subwoofers!!!!

It would have to be a 4" flared port like Parts Express sells, the air speed is high. The port would need to be 22.5" long.

Should I stick with building a slotted port or do the tube port.

Re: Building Custom Subwoofers!!!!

Personally I'd go with the slot port, it will have a lower air speed.
