Smoove Posted August 18, 2013 Report Share Posted August 18, 2013 As the the title states. I just upgraded my amps. My compoments are rated 90wrms and the are 2ohm. My new amp does 150w @ 2ohm. So should I use -0 or -5 to with the DD-1 to set my gains?

matt14 Posted August 18, 2013 Report Share Posted August 18, 2013 If you are worried about it, then tune with the 0db tone since you are over powering the drivers. Or tune with the -5db and see if they can take it. My 80rms CDT's had 125 going to them through a nendo 1000c4 ( 125 per channel ) and seemed to take it just fine.

kickass audio Posted August 18, 2013 Report Share Posted August 18, 2013 I would just use -5db. I have it so my mids and high are at -5db and the sub is at -10 and have had no problems. Now are you running active or passive crossovers? The only time I had a problem is my tweeters did not like the extra power and I blew one tweeter up when it was on a passive x-over setup, I fixed it by going full active and turning down the output level of the tweeter stage so it wouldn't get as much power and has run perfect for me ever since. I have a pair of RF t1652-s mid's going to a SAX-200.4 and they sound great and it is wayy past its rated RMS power but they don't get warm, smelly or sound like crap. Before the 200.4 I had it on a DC 175.4. I have the tweeters with a pair of RF t-1 tweets that came with the t1652's and have another pair that are the AA tweeters that come with the carbon mid's. They sound great but as I said I had to turn down the volume on the tweeter stage because they would get all crackly and sound like shit from the power being too much for them to handle.

Smoove Posted August 18, 2013 Author Report Share Posted August 18, 2013 I am running passive crossovers with the amp set at HP 65hz. I just set it with the -0db 1kz track 2. about to go see how it sounds.

kickass audio Posted August 19, 2013 Report Share Posted August 19, 2013 I wouldn't advise you to use -5db then for your xover setup. -5 will get more output than 0 and you don't want that for the tweeters. If you can bi-amp I would keep the tweeters at 0db and the mids at -5 because the mid's will take more power and the tweeter's won't like that at all.

Jessica Posted August 19, 2013 Report Share Posted August 19, 2013 I think a lot of music is recorded at like -10 to -8. Open a few tracks you will listen to in audacity and see what they peak at. I have noticed that a lot of times snare and kick drums might peak at -5 but the rest of the song is like -8 to -12. It's those peaks you have to watch out for.
