The Dude Posted February 26, 2017 Share Posted February 26, 2017 Ok here is the back story. I have been running a TTLS in my system with good results. I was using a Behringer Inuke 1000 dsp, which seemed to work fine. I didn't know care for the fan even after I swapped it out with a quit version and the leds drove me nuts. I also am planning on giving a pair TH spuds another try once my room is done. So I thought I would start seeking out another sub amp. I sold the Behringer and started looking for another amp. in the mean time I was using my Bryston 2b-lp bridge for the sub amp. Things were sounding good, except the turn on thump from the Bryston was driving me nuts. I had my mind set on a crown K2, but was in Guitar center yesterday and seen that they had the Crown XLS 2502. I liked how it had the dsp and the fan only kicks on when needed. They have a 45 day money back guarantee, so I figured I would give it a try. Its rated at 440w at 8 ohms, 775w at 4 ohms in stereo and 1550w at 8 ohms, 2400w at 4 ohms bridged. I thought by sure this thing should have more than enough head room for the ttls, maybe not were I want to be for the spuds when I go that route, but it has to be better than the Behringer Inuke 1000 dsp. I was running the Inuke in stereo to the TTLS and seemed to have plenty power to push the TTLS. So here is my problem, I have found I have that I have to have the crown gain cranked up (half way) running in bridge mode and the gain up to +5 db on the receiver, to really notice the bass. As before, I did not. I did have the gain up quit a bit on the I nuke, but the gain was low on the receiver. Any ideas, am I missing something important? Maybe the extra power wasn't necessary and I only have a marginal gain. Just when I thought I had things figured out, I guess I don't. 1 Quote Link to comment Share on other sites More sharing options...
SWL Posted February 26, 2017 Share Posted February 26, 2017 I can only tell you that I have a K2 and EP4000's in the house and the EP4000's sound way better powering my THTLS subs. Way more power than is needed but it's what I got and it works great. Especially since I love running the K2 on my mains.No turn on thump etc.Sent from my SM-G920R4 using Tapatalk Quote Link to comment Share on other sites More sharing options...
minermark Posted February 26, 2017 Share Posted February 26, 2017 I think you are "Missing" some nice BIG EAW Stacks, able to "Perform" with anything you plug into them 1 Quote Link to comment Share on other sites More sharing options...
SWL Posted February 26, 2017 Share Posted February 26, 2017 Guys more in the know here will tell you that 50 watts is plenty to power that sub. I think placement/location is what you need to pursue. My TTLS will only make bass in one location in my room. That's it. Subs can be a PITA.Sent from my SM-G920R4 using Tapatalk Quote Link to comment Share on other sites More sharing options...

The Dude Posted February 26, 2017 Author Share Posted February 26, 2017 What is your input sensitivity level set to ? I have tried both, .775 seems to get me more output from the sub. Quote Link to comment Share on other sites More sharing options...

The Dude Posted February 26, 2017 Author Share Posted February 26, 2017 In a corner? Downfiring? Upfiring? Sidefiring? Sent from my SM-G920R4 using Tapatalk About two feet from the corner, down firing about 18" from the floor. I know my room has alot to do with it, which i need to get done..

SWL Posted February 26, 2017 Share Posted February 26, 2017 I was told 1-2" from the side wall and 8-12" from the other wall. After experimenting I settled on 2" from the sidewall and 10" from the other wall. A few inches made a big difference.Sent from my SM-G920R4 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
RoboKlipsch Posted February 26, 2017 Share Posted February 26, 2017 turn the gain up on the amp input. halfway may seem a lot but its a gain control not volume. 2 Quote Link to comment Share on other sites More sharing options...

I usually try to find a sweet spot and live with it. Quote Link to comment Share on other sites More sharing options...
RoboKlipsch Posted February 26, 2017 Share Posted February 26, 2017 it was working before so it sounds like the amp gain is too low. 1 Quote Link to comment Share on other sites More sharing options...
