Paul W's Raptor:

HTGuide Forum - The Raptor ... a 10" MTM

18 Sound ND1460A, horns are the 18 Sound XT1464

ND1460A - HF Neodymium Driver

XT1464 - Constant Coverage HF Horn

18 SOUND_ND1460A ND1460A

18 SOUND_XT1464 XT1464


..if you can take the narrow directivity pattern.. the combination is something of a bargain.

Sounds great, no colorations observed. No foams used. Feels plastic but strong.
Is that your actual measurement of the Selenium D220Ti in said waveguide?
If so, that's actually pretty good vs some of the curves I have looked at !!

Yes. My own measurement. I was surprised myself. Had them in the garage for a year and never bothered (too skeptical to be that good)

1m, on axis, indoor. 5ms gate. I use them for my dipoles.

Dan, why would you measure at the lip axis?

Cost about $14.

Clones:

Pyle Pro PH612
Dayton H6512
YD-L033 (Australia)

Dr Geddes performed measurement of this waveguide:

The usage of this waveguide is well established:

Use Selenium D220Ti or D2500Ti-Nd, 8 Ohms.
