geoff. Posted October 15, 2021 Share Posted October 15, 2021 I’m looking for a pair of CF-5. Dual 15” woofers and the K-510 in the middle crossing at 800 hz. Anyone got the plans yet? LOL! 1 1 Quote Link to comment Share on other sites More sharing options...

billybob Posted October 15, 2021 Share Posted October 15, 2021 Someone posted a couple of years ago a speaker pic of the de appolito, but not as efficient, as the Roy CFs. No plans though. Could well be posted in the CF thread. Since talking 510 horn, guess above poster with the 904 idea could work. Roy may or not have considered a 5...

Which might be my next speaker some day. 2 15" drivers flanking a coaxial horn, so, now a three way design. 3 Quote Link to comment Share on other sites More sharing options...

Could go higher, but I think lower would be pushing fatigue at live levels. Most of the pro stuff lets the woofers exercise a little higher and I am sure there is a reason for it. I think the CF-4 crosses at 1500 hz. Quote Link to comment Share on other sites More sharing options...

What do they compare to in the heritage line? Guessing they might be closer to RF7s? I picked up my CF-4s in February for $1500. They were pretty mint and version 2, as I'd expect for that price. From what I understand, version 1 is the best, with 2 being near as makes no difference as good, and 3 being notably not as good as 1 and 2. I think my $1500 was on the high side, but like I said pretty mint, good version, and I looked for months to find a pair in the color I wanted so I was ready to jump even at that price. Here in the Minneapolis metro there are some Oak CF-3s for $800 on Facebook. https://www.facebook.com/marketplace/item/302311454620549/ 2 Quote Link to comment Share on other sites More sharing options...

Maybe someone will correct me if I'm wrong, but it seems to me that the mid horn/driver pair has less distortion than a woofer / subwoofer cone. I play around with an online tone generator when chatting about tonal ranges, or working on crossovers (just so that I have a mental gauge for what "X" hz works out to be): https://www.szynalski.com/tone-generator/ 1 Quote Link to comment Share on other sites More sharing options...
