If you can find it, audition Charney Audio speakers. They employ a fairly large quarterwave rear loaded horn on 8” drivers. The bass is remarkably good. Voxativ does the same. Doing it right involves some fairly complex woodworking for the cabinets which means it is not a cheap approach even if there are savings from having just one driver and no crossover.
How much does rear horn loading add to full range driver?
Found a tower speaker using a single 3" full range Tang Band titanium driver. The rear wave is horn loaded via the 43" tall tower. The speaker had some pretty good reviews.
I listen at lower volumes in a smaller room.and actually have some Norh 3 drum speakers using a 3" Tang Band driver. The enclosure is roughly LS/35A size and ported. For vocals they are loud enough. Norh claims they play down to 75hz.
How much volume is gained by horn loading the rear wave? Would a horn enclosure 43 x 9 x 6" inches be likely to play lower than a ported shoebox size speaker? These wouldn't be my main speakers, just an interesting addition.
Thanks,

I've listened to numerous BLH Fostex cabinet designs using drivers in the 3"-8" range and could hear usable info down to around 50Hz, depending on how close they were positioned to the front wall/corners. This said, the sound down there was somewhat disjointed from the rest. A few exceptions to this were (#1) speakers from The Horneshoppe. Not certain what to call the open backed cabinet design, but the sound was nicely balanced (they used a 3"-4" driver and I only heard them once placed in corners). The other (#2) was a wide/flat TL (open @ the bottom) that used little Ted Jordan drivers. The cabinets I heard them in were DIY (made from some plans on the WWW). Here's a YT video of a similar/like speaker and I think that it uses the same driver (looks the same).

@larryi thanks for the Charney tip. Hadn't heard of them. @dekay , I have heard of the Jordan modules and The Horneshoppe. I was looking at $2450 Acoustic Technologies Classics. The head of the company passed away and a friend is selling them new for about $350 shipped. Just wasn't sure how much a rear loaded horn could add to a 3" driver. Thanks, Aldnorab |
