Dayton Reference Subs; HO or HF

[SE-Raider]

If used in a sealed enclosure, sized for .5 Q, which driver would be best?

If it's for a sub use the HO version. If it's for a woofer use the HF version

For the first time, I think I'd have to disagree with you, Thomas. I'd say for sub use ONLY use the HF version. It goes lower and higher. Plays louder. The caveat being that the HF version needs the enclosure to be two to three times bigger. Who needs these <1cuft boxes, anyway?

yeah i thought it was HO version for tiny boxes, and HF version for larger boxes

I have the HF for sub purposes and I find it to be rather fantastic. It plays deep good and loud. A little bit muddier then my last driver, but less then half the cost. I feel like the biggest drop is after 29hz. Still plenty audible just seems to be where it lops off the most. I'm not sure what the graphs say. I like to test with my ears... I haven't heard the HO version so I can't really say my thoughts in comparison. Three cubes sealed is a little big (if you ask my wife anyways), but a 1 cubic foot box would have looked too wussy anyways. I only run it up to about 65 hz, but when I build the modula's using the peerless driver I'll run it a little higher.

Volumes for these drivers

What would be the optimal volume for a Q .50 for these two drivers? Also for the RS180 while we're at it. The Linear Team site I usually use for these calculations defaults to .707 with no option to change. Are there other good sites on-line for enclousre calcualtions? thanks

If you download Unibox you can tell it to design the box based your choice of "Q".
