Re: Amp for Dayton sub

Give us some more info. What's the net volume of the cabinet and the tuning frequency?

The pic of the cabinet shows a port on the bottom. What is the tuning frequency?

Re: Amp for Dayton sub

Understood. A 100 watt amp would be lots since the sub has limited Xmax:

http://www.parts-express.com/pe/show...number=300-802

But the 240 watt amp is on sale for $99.

http://www.parts-express.com/pe/show...number=300-805

The 240 watt amp could be used in the future for a bigger sub if desired.

Re: Amp for Dayton sub

Go for the dayton 240 while its still on sale. Just don't turn the gain up too much.

Where did you find that box design? I'm not sure I'd recommend that. Now, if it was a horn loaded design maybe, but I'd just go for a standard ported box. Any reason you wanted to go with that design?

Re: Amp for Dayton sub

Agreed, 100W will be plenty for that sub unless its in a tiny sealed box. I used the same sub in a vented build about a year ago (Tower Sub in my sig), the 240W plate amp was the same price as the 100W so I got the 240. As predicted, the sub can handle nowhere near 240W. On the bright side: clipping the amp won't be a concern and the 8" RS-HF certainly has a considerably higher suspension limit than it's actual xmax, and the sound the RS produces is smooth and musical.

If you get the 240W amp, set your gain based on audible distortion. That is enough power to make it bottom out unless you keep the gain appropriately low. That sub should sound nice for music, just be wary of stuff in the rumbly range of HT content.
