Orion HCCA 12D wiring questions 250G4 vs 275G4


Recommended Posts

Hello,

I am looking for the expertise of those who know the orion equipment. I am a long time fan of the Original Orion 12d speakers. Some say the 15d's are the way to go but I like having some room left in my cars. Many years ago I was fotunate enough to have 1 in a factory orion box with plexi side and rectangular port. I loved it and it was plenty loud and clear for what i wanted. I powered this one 12d dual 2 ohm voice coil speaker with my 250g4 amp. 1 ohm bridged provided this with 800 watts. I am much older now and ran across a deal recently and aquired 2 mint condition 12d speakers. I still have my original 250g4 but have also just aquired a 275g4. I know the specs for both of these amps and have seen quite a few videos and comments about the TRUE output of these amps compared to the ratings. I've seen people say the 275g4 is 1200 at 1ohm at 12volts and at 13 and 14volts its upward of 1600 to 2000. I have also seen peoplesay the 12d's rating of 1200w is more like 2000 max.

Data states .5 ohm stable in stereo how about mono? I would prefer the two wired down to the .5 ohm load but i do not want to blow these 12s.

Do I play it safe and do the 250g4 at 800w to one 12 at 1 ohm and then the 275g4 to the other at 1200w 1ohm

or wire them together down to .5 ohm and just use the 275g4 and see if the amp and the speakers can handle it.

I could have went with the new hcca's but i did not want a set of speakers with that much weight and i also did not want to have to supply them with that many watts.

250g4

200x1 @ 4 ohms
400x1@2ohms
800x1@1ohms

275g4

Power ratings at 12V and 0.1% THD:
2 x 75W @ 4 ohms
2 x 150W @ 2 ohm
2 x 300W @ 1 ohm
2 x 600W @ ½ ohm
1 x 300W @ 4 ohm bridged
1 x 600W @ 2 ohm bridged
1 x 1200W @ 1 ohm bridged
THD: 0.1% (4 ohms, 20Hz ∼ 20kHz)
S/N Ratio: 100dB
Damping Factor: >400
Freq. Response: 20Hz ∼ 20kHz (±0.25dB)
Linear Bandwidth: 6Hz ∼ 50kHz (±3dB)
Fuse: 6 x 30A
Dimensions: 25" x 10.25" x 2.25" (63.5cm x 26cm x 5.7cm)
Manufactured in 2000. G4 stands for 4th Generation

I am asking for advice and or real data for the two.

Thanks for the help.

You wouldn't be playing it safe with two different amplifiers running different power on the same drivers in the same enclosure.

You can't get .5ohm stereo with dual 2's because they'd need to be on the same channel (parallel parallel) You can only get 1 ohm stereo or .5 bridged.

Edit: and don't ever wire lower than the rated bridged impedance.
