Beyma TPL 150 or Raal Lazy Ribbon

[3GGG]

Has anyone compared the two? Thoughts on either driver? They will be used in a horn system above a fane 8m in a 120 hz tractrix horn and a Yamaha 6681B in a 200hz Tractrix horn. Probably from 10k up but the system will be active so cross over points can be varied.

the Beyma TPL150 has its strenghts specially in the 1,2khz to 10khz range, being able to reproduce voices with incredible naturalness . In that range, i do not know ANY compression driver that comes even close. Your Yamaha 6681 will not sound better. Beside this, its after all a quit big advantage to have a frequency band from 1,2khz up covered by just one driver, without crossover in the signal path.
I still use the midrange horn in my system. I replaced Vitavox S2 with Coral M100, do pad it down however. It plays parallel to the TPL-150 and helps to open up soundstage.
Recently i took off the backchamber of the Beyma, and it adds more depth and body to the sound.

I've got both the TPL-150H and Raal 70-10 at the moment. The Beyma is brilliant from 1.2k to 10k as Angelo says. I havent heard a CD that I prefer either. But to my ear (I might be alone here) the TPL can certainly benefit from EQ or a supertweeter above 10k, so it wouldnt occur to use it only above 10k. Its good good body and tone, but isnt as filigreed up top as the Raal which will be at an easy advantage >10K I reckon, also dispersion wise. Few things do the top octave better than Raal imho. cheers

Thanks guys, might get the Raal for now and play with the Beyma in future, they do seem to be getting lot of good reports atm.

i'd love to play with ribbons, but it goes against my no caps in the crossover thing. how are you planning to deal with the RAAL with your digi XO?

[3GGG]

A pair of 40uf caps should do it. Not ideal to introduce caps but there is compromise in every design i suppose. Replacement ribbons are easily obtained from RAAL.

yeah i'll probably get past it and just try them, but i'll probably try the accutons first. both are a ways off yet

I see you are starting to look at diy speakers. I am sure whatever you build they will be of an extremely high quality going on your other completed projects.

Another vote for Raal over the Beyma for the top octave. Used both, no contest for the highest range. Down lower though, the Beyma is excellent. I third the opinion that it is nicer than most compression drivers I've heard.

thanks, yeah just getting my feet wet at the moment. i resisted the temptation to dive in head first with some audiotechnology C-Quenze, dome mid and accuton or RAAL and stuck with a pretty tried and tru 2 way with revelator 18w/8531g00 and 2905/9700 digitally crossed. amps are all sorted but yeah the speaker build choices are baffling (no pun intended) so just gonna do what i can with a pretty standard bass reflex with high quality drivers and save the experimentation for the next build once i have a bit more experience.

where did you end up getting your ply in AU? do you have your own workshop, or did you go to a cabinet maker? i'm doing a variation on the troelsgraven SP98 to start and they'll stay in the studio, the next ones will be larger mains, but its not something i want to drop 2k on blind.
