I own a few of these and power two a side with a 5000i stereo. Was wondering what everyone else was using to power there danleys.


Thanks!

Which impedance cabinet do you have.  The origional ones were 8 ohm.  After a couple of years the standard impedance was changed to 4 ohm-due to people having a hard time providing a large enough amp for them.  8 ohm is still available-but the standard is 4 ohm.

The impedance will affect how you power them-to get the most out of them-as with any loudspeaker.

I see a lot of posters on here tend to use an iTech8k for a pair. No personal experience though.

I use IT8Ks to power 4 of the 8ohm Th115s

Thanks Hal and everyone else. I have the 8ohm version. 

How do you like the 8ks for the sub? It doesn't seem that much different than my 5000i. Maybe a few more watts but the db level wouldn't be noticeble. Correct?

If you can afford it I am getting good results powering my eight ohmTH-115s with Lab Gruppen FP+14,000 and its more expensive brother PLM 14,000 with good results.
Two boxes per channel.  When we are stretched thin I sometimes do three boxes per channel, they seem to roar even louder this way.

xti6000 powers one 4 ohm TH115 a side.  For my uses it provides enough gut, but I rarely use them cranked up and outdoors - would like to hear them ripping, powered by an I-Tech 8000.

+1 on the I-Tech 8k and TH-115 combo. I've been running 4 (8ohm)115s + an I-Tech 8k for several years and love the performance.

I've looked at the specs on the 4ohm version and they are 106db vs 101db at 8ohms for sensitivity. So at 5db more a box roughly..assuming specs are accurate that's almost 30dB extra in sub output. Correct?

Should we be switching to 4 ohm drivers?

Incorrect, and no.

Danley speakers use a standard voltage as a reference for sensitivity. That means the 4Ω version is getting twice as much power as the 8Ω version at that standard voltage. If your amps can deliver double the power into half the impedance you are using now, you will get the benefit of the higher power levels.

A 5dB increase per box in a 6 box array does not mean a 30dB increase for the array. It is just a 5dB increase.
