andale927 Posted October 12, 2011 Report Share Posted October 12, 2011 Hi guys, I just recently bought a used BTL 15 D2 because it was such a good deal that I couldn't pass it up. I do not have enough cash to power it properly so until that happens I was thinking of just building a box as if it would go in my trunk but keep it in my room. I have a Klipsch Sub 12 with a 300w plate amp... so I was thinking of using that to power the BTL. I was wondering if you guys would give me any input on how the BTL will act with that low power in a big 4.2cuft box. It will not hurt the sub even if it is clipping right? Because the most wattage that could be thermally be produced by a clipping 300w amp would be 600w? Right? Also how do you think it will sound haha? Sorry I think I rambled a bit...

andale927 Posted October 12, 2011 Author Report Share Posted October 12, 2011 Also I think that the plate amp probably has a built in high pass at around 20hz that cannon be changed? Will that be a problem below my 32hz tuning? I am not sure if 300w can make a woofer over-excurd (idk if thats a word) even far below box tuning.

armykyle1 Posted October 12, 2011 Report Share Posted October 12, 2011 (edited) clipping is bad period..... You can kill the baddest sub with clipping on low power. I haven't seen anyone use a BTL in a HT style box.... If I where to do it, I would probably do 5.5-6cubes @24hz Edited October 12, 2011 by armykyle1 Quote TEAM XS POWERTEAM HEAVY HERTZMy build- http://www.stevemeadedesigns.com/board/topic/194454-e46-bmw-build-pos/#entry2914134youtube- http://www.youtube.com/user/armykyle1big build starting Link to comment Share on other sites More sharing options...

eaglescorpio1 Posted October 12, 2011 Report Share Posted October 12, 2011 ok.... two things hurt speakers. overpowering them and running a clipped signal to them. so yes, clipping the amplifier to your sub will hurt it regardless if its 300 watts or 2000 watts. and on that low of power, i don't believe a low frequency will hurt that btl as long as your not running a clipped signal. if i am wrong on either of these, please someone, speak up.

andale927 Posted October 12, 2011 Author Report Share Posted October 12, 2011 Thanks for the responses guys. I don't think I can wait till the time it takes for me to have enough for an amp so I am going to do it anyway But I will take what you guys said into account. I have access to an oscilloscope so I can make sure that the amp isn't clipping. That being considered conclusion = 300w will be okay as long as its not clipping at all?

Supercharged DCs Posted October 12, 2011 Report Share Posted October 12, 2011 300 watts probably won't make it move much, but as long as it's not clipping I see nothing wrong with it.

kickass audio Posted October 12, 2011 Report Share Posted October 12, 2011 as previously mentioned it will not get that btl to move at all, it will play the frequency but wont hit at all. you also can really cook a sub if it isnt moving and you clip it. I have seen this with my SMD. If i play a clipped song at full tilt it barely gets warm and doesnt smell but if i play it at a lower volume but its still clipped a little, it gets even hotter. The reason for this is because the sub uses the high excursion to cool off the coil and inner parts of the subwoofer. The more excursion, the more air flow it produces, the more air flow it produces the cooler the coil will be and the more power you can toss at it. I have 5kw of clean power going to a single SMD 18 sub and as long as i dont clip it, it stays perfectly cool and does not smell. I have had the sub for a few months and it handles the abuse im giving it like a champ.

andale927 Posted October 12, 2011 Author Report Share Posted October 12, 2011 Kickass Audio, Thanks! That actually makes a lot of sense. You have furthered my knowledge,I will definitely set my amp with an oscilloscope then. Thank you everyone! Quote Link to comment Share on other sites More sharing options...
