Say I'm using Tsi100's for a party, how many watts should the amp be to be loud enough to fill a 25*25 m space?

    That is 15,625 cubic feet. The square root of that is 125, so in order to have some reserve, it appears 200w/channel is required.

    wow, that's quite a lot of power. Doesn't the speaker efficiency effect the calculation?

    They are 8 ohm 89dB bookshelf speakers. They should be fairly easy to drive. What electronics do you currently have to drive them with or are you looking to buy something. I wouldn't spend too much on electronics given the speakers only cost $219 new. Let me know if you need suggestions
    Rig1 - Totem Hawks, Benchmark HDR, Parasound A21, Sonus, Samsung 52 LCD, Audioquest Type4
    Rig2 - LFD LE IV Integrated, Harbeth P3ESR, Rega Dac, MF V-Link, IMAC, Audioquest Type4

    I'm looking at the Pioneer A-20 or Onkyo M-282. If I have enough cash left I might consider changing the TSi100's for RTiA1

    It'll be great if you can give me some suggestions, I'm looking for a 2 channel amp, with atleast 60W per channel

    I did the math wrong (darn beer). I used 25 as the height for the cubic feet. However, ceilings are usually 8 feet high, and that results in 5000 cubic feet. The square root of that is 70. Throw in some reserve and you have a minimum of 100w/ch. However, if the speakers only cost $219 a pair, I suspect you might find it difficult to be "loud enough" for a party no matter how much power you have.

    Oh I see, so you're suggesting that I look for some higher efficiency speakers?

    No, not really. Efficiency is certainly useful, but isn't the only, or primary, quality in speakers. First, I was kidding with the math, but the results are reasonable. Go figure. Anyway, I might be wrong, but I suspect if the electronics are up to par then the speakers might start to breakup while trying to be loud in that space. This is only a guess, but I bet the TSI100s are great for an office, or other small room, while not quite there for loud levels in a bigger room.

    I'll do some math for ya.

    Big room + small speakers + very loud volume = buying new speakers after those get toasted.

    Thats a pretty big room and to fill it with sound at the levels your suggesting isn't going to end well with those speakers. Buy something made for the abuse like Cerwin Vega or even Klipsch. Better yet, look on your local craigslist for a 50 buck pair of tower speakers, blast them to all hell for the party, if they survive keep 'em around, if not oh well.
    HT SYSTEM-
    Sony 850c 4k
    Pioneer elite vhx 21
    Sony 4k BRP
    SVS SB-2000
    Polk Sig. 20's
    Polk FX500 surrounds

    Cables-

    Acoustic zen Matrix 2 IC's
    Wireworld eclipse 7 ic's
    Audio metallurgy ga-o digital cable

    Math is wrong, you're looking at roughly 52812.5 cu.ft with an 8 ft ceiling. that was a 25 x 25 meter room, not foot.

    For party speakers, you want large displacement drivers for the combo of high volume and punch. Can someone say Cerwin Vega!?!
