IPR2 3000 with DTH4s

[Russell Hornsby]

I run a Mardi Gras float in Houma, La. We have for years run 4 DTH4s (1000 watt program) on one channel each. We use a mixer to an equalizer, to a sonic maximizer, to a crossover then to amps to speakers. Very clear and loud. Amps are turned up all the way and we use the mixer to control the level of sound. My question is: Can we run 2 DTH4s on one channel saving us an amp for extra if needed with the same level of sound coming from each speaker? We do run SP2s in parallel using 1 channel for 2 SP2s and it seems to work well. Just not sure about the DTH4 and their older crossovers.

The DTH4's are a 4 ohm load speaker. The IPR2-3000 is 840 watts at 4 ohms per channel. In simple terms you can give each DTH4 up to 840 watts rms using a single amp channel per speaker. The speakers are listed at 600 watts rms, 1000 watts program so you are right about in the middle of their power handling run that way and I see that as a good power match. If you run 2 DTH4's on an amp channel it will see, at least, a two ohm load. The amp is listed at 1490 watts at 2 ohms per channel. That will be divided up between the 2 speakers for 745 watts available per speaker so you would be down about 100 watts per speaker which isn't a lot but you will be running the amp on the edge as far as ohm load. For the price that amps are going for now I'd just run things as they are and purchase or rent an amp to run your Sp2's if need be. You have a good setup now so I wouldn't run one amp hard just to run a few more Sp2's.
