Can a 2.5kva generator power 2 x TS315 generators

Hi! We are planning on buying 2 of your Alto TS315 2 way speakers.

Would you please be able to answer a question that all the shop assistants in the country that sell your product cannot answer.

We are going into a remote area without electricity and so our sound needs to run of a generator. The one we have is 2.5kva with a power factor of 1. We would like to know if this will be sufficient to run the two TS315 speakers?

    Treating the power factor as .9 for the worst case you will still have 2,250 watts available and being that your speakers are only rated @1,000 watts rms the actual consumption will not be the full 1,000 watts because you will never have a continuous white noise (full spectrum of sound) running flat out, inside your amp you have capacitors in the circuit to store the energy so if you was playing deep house the thumping bass is only 2 beats a second, mid and top frequencies don't use as much so you could say that if you was playing the speakers at the top of its limit where the red light flashes it would consume 4 / 500 watts per cabinet, so the generator will cope, if your running some lights just keep to LED fixtures?

    My son-in-law invited me to Koh Phangan, Thailand to Dj for a 6 month period so I shipped my sound system out there, which is a 6K 4 way rig, the club I was asked to cover, they didn't have wall sockets just a 5 amp twin flex (no earth) with a double socket on the end, the other end had a dodgy plug which was fitted directly into there fuse box, I was very concerned that the evening would not go well, there was 4 Dj's playing over 4 hours non stop, curiously I went a few times to check the fuse box and twin flex and touched the plug and it wasn't even warm, this completely surprised me but it goes go to show that the 5 amp supply stood up well owing to the capacitors storing the power.

    I should have said 'Pink Noise' in the last post, this is slightly louder with an enhanced bass apparently.

    BTW the subs are 21" PD (all Precision Devices) Bass 18" PD, Twin 10" Mids & twin 1.5" compression horns in the top cabinet, very heavy but what a sound. Yamaha P7000 series amps, 4 way active crossover plus a sound enhancer, I was trying to sell out there before we left, but no one had the money so I shipped it back to the UK, much to my annoyance it was double the price I sent it out at, bastards.

  • Wow, thank you so much for your reply! :) you mentioned 1000w, that's the rms for the TS315 2000w 15" 2-Way Powered Speakers right?

  • Alto rate their cabinets as peak power but the rms figure would be half that, its called marketing, lol. I would say yes, both would draw up to nearly a KW of power, if you can understand that if your TS315 was running flat out with 'Pink Noise' it would probably consume just over a KW maybe 1100 watts each being they are Class D amps which are known to be 90% efficient, but as I mentioned under normal dance music format it would never be running continuously flat out, with a thumping bass signal only lasting milliseconds, your red peak light will just flash letting you know the amps limit, but overall consumption wouldn't be the rated output just playing music as some of the energy is stored in the capacitors so when its needed for peaks it can handle it, alternatively when there is no music being played the power consumption would be around 40 watts each, I hope this is helpful. The best sound would be from an active 3 way cabinet, Bass, midrange and top (treble) but they are a lot more dosh, good luck.
    A friend has 4 of these and we changed the 15" driver to a better quality unit the Eminence Kappa Pro 15 (4 ohms) a lot more money but twice as loud at the same level, every 3dB is doubling the SPL, (sound pressure level) Alto never say the SPL on their replacement driver as I tried to look it up but I guess looking at the ones we took out they are a fairly cheap unit with no manufactures name on them like JBL, Ohm, Electro-Voice, (EV) Beyma, PD, Eminence, B&C, Fane and 18Sound, I may of forgotten some others but all these are quality units but do cost a lot more.
