Open baffle speakers


Open baffle speakers design is the simplest , to get bass response similar to other design , like ported, the baffle size must be huge to avoid low frequency degradations . Tipical size the baffle   width 10-20"  got weak  bass performance.   I am wondering how open baffle speakers design became so popular ?

I own two sets of Open Baffle speakers - Legacy Empires and Jamo R909s. The R909s dont need it because of their design, but open baffles are capable of making a healthy amount of low end if you compensate for the low end drop with an EQ. Both of my OB go down into the 30s and kick drums sound huge on them. I dont know if its specifically the fact they’re open baffle, or simply the diameter of their woofers, but kick drums through literally all of my other speakers I have or have owned sound small in comparison. They’re also both extremely tight and have very even response in the low end and midbass... hilariously I think one of the best types of music for open baffles are dance music and modern pop like Tate McRae, when most people running these speakers are listening to orchestral and jazz. The quality and size of low end and midbass is just so good, and the trend in recent productions are large reverb washes and stereo fx that sound great on an open baffle’s soundstage.

Also on both of my OB vocals sound very big.

@phasey Why do Reference 909 not need EQ because of their design? As far as I recall they're plain-jane, drivers-in-a-plank-style open baffle speakers. Although their woofers are quite substantial they should have the same low-end behavior as other, similarly designed open-baffle speakers like Caladans and such. Thanks!

Jamo R909 uses unusually sensitive woofers so they’re louder than the other drivers by default with a rising response, then a filter in the crossover is used to drop the level of the woofers at exactly the rate of their low end rolloff. The result is a passive open baffle speaker that doesnt need active EQ to make up for a drop in low end.

If money is no object, one of the finest OB's out there is the Songer Audio.  It sets a standard I haven't quite heard in any OB speakers.  And the build quality is second to none.  Get ready to write a serious check, though.  https://songeraudio.com/

 

Box speakers with multiple drivers create a slew of problems: cohesive sound across the drivers, degradation in sound quality from cheap connectors and crossovers, uncontrolled sound waves bouncing around inside the cabinet, and a waste of money on cabinet design and manufacture. Get a world-class single full-range driver for the cost of an entry level box speaker. You can even get excelllent quality sound from a $400 set of 15" Lii drivers. Or use an 8" driver with a good sub for the lowest frequencies; it's the right tool for the job. Life is as hard as you make it.
