I built a 5 cu ft vented cabinet for an RSS390HF With a 4" x 12" port. Box tuning is 21.5 Hz with an F3 of 23. The lowest it will go 30 Hz. Come to find out that sometimes WinISD looks good on paper but not in reality. So, I figured I have the box I should just replace the woofer with something that will give an F3 in the low twenties. I'm looking for recommendations. The port is removable. Tommy D

Is that the 15" HF driver? If so that is a small box for that driver and with a 21hz tuning the response will be rolling off at 30hz. Also the single 4" port will likely get overloaded by that driver easily. What is the amplifier used? It may have an ssf engaged.

Yes, it is the Dayton 15". I did have another sub in the same corner with good results. I did a near field in the center of the room and it started rolling off at 30HZ. It is powered by a Dayton HPSA 500. I did try boosting the low end and that didn't help. Tommy D

I tried the amp on another speaker (Peerless XLS12 w/ passive radiator) and it went down past 25HZ. I have had others say that the cabinet is too small. A bigger cabinet would be hard to meet the WAF. So, an IB could pass the WAF if the RSS390 can be used. That would save $$$. But, I'm not going to rule out another speaker. I'd rather just get another speaker. Less work. Tommy D
