Hi for PA levels, I wouldnt use my 1" driver crossed over at 1KHz, at home it is no problem. I use a RCF CD1710MT3 on RCF H100, the neodyme version is still available. The Celestion CDX1-1430 is also told to work that low on Stereolab 400 horn (home use).
For PA and home use I would think about bms 4554 and B&C ME90:

BMS 4550 crosses at 800 Hz vs. 1 kHz for 4552nd.

fb, maybe we are getting away from the price you had in mind. How are you with your project? For a PA the 1K xover would not be a problem but for high resolution (home/HiFi system) I would go with the <500Hz or >1600Hz region xover. Maybe that's not a difficult choice for you.

Inductor, and everyone else, thanks for your replies. The beyma stuff is getting a bit too expensive. And I want to avoid waveguides with sharp angles at the mouth or throat.

GM, I have considered getting a waveguide CNC cut to my specs, but am concerned about cost. Doing it by hand is beyond my skills and time availability I think.


Zilch, you seem to know your way around quite a few waveguides, what would you recommend for the 4550? Perhaps the low cost of the 4550 might offset the expense of getting a waveguide built.


Panomaniac, do you have any other experience with Radian drivers?





Thanks all!

Just for the books (not forgetting) keep also in consideration the 0.7-23kHz 100dB Beyma TPL150H, flat from 1K-20K (or TPL150/w.no horn). Thanks bm, have a nice DIY.

No, just mine. However, you may want to have a quick look at this post:

Also see posts #140 & 141 of the same. Talking about the 950 in this case.

I suspect 4550 on XT1086 is going to get the job done for you, though I've never done more than bolt them together here.

A favorite of mine in this cost range is BMS 4555 on ~$100 1.5" JBL PT-F95HF, though I haven't tried running that combo below 1 khz. The square PT-H95HF will play lower, and is the best-sounding of the JBL PTs, in my view, if you can work with its additional depth and greater requisite c/c distance.

At some point, you've got to get empirical; there are thousands of possible combinations, and hundreds of members on this and other forums willing to speculate ad infinitum about what might work, when for ~$500 plus some filter design skills, all will be revealed, up close and personal....

You didn't listen to 4550+XT1086?

The 4555+JBL 1.5" probably won't work out, BMS' recommend 1000hz, and the waveguide's much harder for me to buy.



I think my 2 options at this point are therefore BMS4550 and Radian 745PB - parts express will do refund on the Radian's if I don't want them. Next step is to investigate the cost of waveguide construction, vs. driving to my nearest city and picking up the 18sound gear.

Nope, but I'll get there, eventually....
