I am dipping my toes into speaker building and have just purchased a 2nd pair of Oris BD150 horns that I can fit up with a pair of Coral Flat 8 II drivers. In an ideal simple world I would like to build some bass cabinets and fit a woofer and a simple XO and drive them all off a 22W SET 845 amp.
To be honest Xmax and Qs are a strange language to me and I dont want to stuff this all up.
What is the best driver choice for the LF driver?, I would love to have super tight musical Bass and I dont need it to go Super super low (but it does need to cross over around 150hz.
I am happy to listen to all suggestions because I really am a bit lost

How big, how loud, how sensitive (you want at least a couple more dB than the Coral in the Oris. BD150 reaches 150 Hz? And how much budget?

Hi Dave,
Thanks for the reply, I will run some tests on the Corals when they are in the horns to work out where they are at sensitivity wise, a recent T&S sweep of the drivers came back around 92.8DB per driver, I expect the horn will bump that a bit, budget is a little bit fluid, less is better, but I would be comfortable up to around $600USD per driver.

Dave, I will be talking to you in the new year about an Onken design for a pair of Goodmans Axiom 301s that I am having rebuiltHow big, how loud, how sensitive (you want at least a couple more dB than the Coral in the Oris. BD150 reaches 150 Hz? And how much budget?

Only from the lower cutoff up 3 or 4 octaves, above thatteh Coral is a direct radiator.

I have done a monster miniOnekn for the Axiom 201. So i expect 301 will work too.
Note that a miniOnken is not officially an Onken, they have quite different tuning.

does that mean the horn has little effect on the efficiency of the driver?
Only at the lowest frequencies, why usually drivers with rising response are used. A horn is only good for 3-4 octaves then it unloads.
