I have a set of a/d/s/ 346is drivers and PX series tweeters, or so I believe...





I am running an a/d/s/ 860mx 8x60 watts for them. I was running 1 channel for each mid, and one channel for each tweeter. The tweeters are more than loud enough with the gain at only 1/4 of the way up. But the mids with just 1 channel (60 watts) are very quiet with the gain turned ALL the way up and the headunit all the way to max volume (alpine 9813).

I have the headunit doing a 3-way, crossover points at 100hz to 2000hz 12db/oct for the mids and high pass 2500hz @24db/oct for the tweets.

Then I tried bridging 2 channels so that each mid would recieve ~150 watts, and even with the gain cranked up and the volume way up, it is still not loud enough at driving levels.

Before I was doing active I had the passives in and had 2 channels ~150 watts going to each tweet/midrange and it was MUCH louder. Is it possible for the passive crossover to make it louder some how?

These speakers I believe to be older a/d/s/ 346is, however they seem to look exactly like the Orion series which was a 2 ohm driver, would that make a difference?

This is my first venture into active, and although it sounds pretty good, the volume is very disappointing. Thanks for any help

i believe they are the hcca 2 ohm mids and not the 4 ohm ads version-same cone etc. diff. coil,the 2 ohm coil wont impact spl of the mid the way you would think ,even though the ads tweets are commonly crossed over below 4 k with 18 db slope,i would try raising the tweet hp to 3.5-4 k 12-18db and for the mid near the same 3.5-4k 12 db,and see how it sounds,if the tweeters are not balanced with the mid and are too loud,it will seem as if the midrange is lacking vol. hope it helps

Thanks, yes it does, but when I try and cros the mids above 2.5k it seems like they get scratchy...

I think that is what is happening, but it might be that they are clipping since I have the gain on the amp cranked all the way up.



This is a pic of the Orion HCCA setup, and I believe that is the same setup I have...

If that is the case, I'm suprised the amp I have can take a bridged 2 ohm mono load... kinda frustrated that I have no idea what drivers I have.

I THINK THE RED BASKETS WERE USED ONLY ON THE HCCA,S,AND YES IF THE GAINS ARE MAXED ON THE MIDS THEY WILL SOUND -SCRACHY-QUICKLY,AS FAR AS THE 2 OHM BRIDGED YOUR ADS SHOULDNT HAVE MUCH OF A PROB WITH THAT,BEING A MID AS YOU MIGHT KNOW IMP. VARIES WITHIN THE BANDWIDTH WHILE PLAYING MUSIC MEANING DEPENDING ON THE FREQ. BEING PLAYED IT CAN VARY BETWEEN 2- WHO KNOWS 20 OHMS OR MORE,THE 2 OHM RATING IS NOM.IVE NEVER HAD A PAIR OF THOSE, LOOKS LIKE YOU DID SOME WORK ON YOUR DOORS-IS YOUR AMP WIRED UP PROPERLY-GROUNDS-SANDED AND SCREWED OR BOLTED TO A SOLID POINT?WHAT GA WIRE-FOR PWR-GROUND?FUSE RATING?CHECK POLARITY-ITS LATE AND IM STATING THE OBVIOUS -SORRY
