SGC ADSP2 Speaker

[Moleculo]

About a month ago, I decided to try out the SGC ADSP2 external speaker and compare it to the Clearspeech 2. Keep in mind that I had both speakers mounted in my Jeep, side by side. I switched back and forth between the two to compare. The speaker has 3 settings for DSP audio filtering: off, -20 db, and -40 db (going off the top of my head here). The speaker's DSP filtering is phenomonal, maybe better than the Clearspeech.



I have a major complaint with this speaker, though. The actual speaker is very small. It's so small it can't handle the volume when you crank it up. I'm in an open top Jeep the whole summer, so I need all the volume I can get. I blew out the speaker within 3 weeks. I sent it back to the factory, and they replaced it. I then blew out the replacement within 3 days.



I then remembered that I had a Texas Ranger speaker laying around that I wasn't using. Anybody that has ever used a Texas Ranger knows that this speaker is one LOUD mother. So, I carefully took apart the SGC and found 3 boards inside and started to figure out how to convert my Texas Ranger speaker into a SGC DSP Texas Ranger killer combo. I wrapped up the 3 boards in electrical tape (they had all kinds of contacts exposed) since the Texas Ranger case is metal. I then drilled holes in the TR case for the SGC button and LEDs. I also added a power on/off switch. After figuring out how to route the wires, I duct taped the little boards to the insides of the TR speaker, mounted the boards, and PRESTO!! I now have the loudest, baddest DSP speaker on the planet. It's a little pricey way to do it, but it sure does work good. BTW, after all this work, I'd just buy the Clearspeech again instead. The DSP in the Clearspeech is very good, and the audio is nice and loud. I just didn't want my $125 SGC investment to go to waste, so I figured out how to make it work right!

Just curious, Have you ever tried running your RX audio through a EQ? Since the external speakers are using DSP after IF it is basicly just "shaping" the RX audio sound instead of filtering the incoming signal which would be the better route. I've found a EQ will do the same thing, has more adjustment and cost alot less. On the base I run the RX audio into a kenwood 200w per ch amp then to a 8 band EQ into a couple of "stage Monitor" speakers. Less than $70.00 investment. Works for me.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT="">

Never tried that...sounds interesting. One question, though...The DSP speakers on the market also perform notch filtering. This can help cut down or eliminate alternator whine in a mobile installation. You can also tell that it works by just running a tone through the speaker. Have you seen this also work with the audio EQ?

I have one of those too, Jay. I was gonna use that one, but I couldn't figure out how to get the @#%$ plastic case apart!!! If you figure out how without destroying it, send it over.... <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT="">
