  • Amp with Bluetooth for Dorm Room

    Looking for a small amp for granddaughters dorm room with Bluetooth capability.m It is not to be a dormblaster so 5 to 10 watts will more than suffice. Using a set of book shelf speakers I build for her. FM is not necessary. See 3 choices.

    1) Dayton audio DAT-2.1 (300-3831) but will not use the sub output. $84.00
    2) Pyle PFA330BT (310-2658) $44.00
    3) Pyle PCA2 (310-2000) $36.00 A poster in the comments stated they have added Bluetooth and FM; that info in not in PE's write up regarding the amp.

    Edit - Speaker cabinets already built, they are to small for the plate amp.
    Wood shop closed, cannot build speaker cabinet so no build sub.

    Thanks for the early comments,

    George

      I'd buy the Dayton. Subs don't have to be big. Tyger 23's Mariposas and DanP's NRNP sub, passive edition.

          Don't laugh, but I think this should be a contender... https://www.parts-express.com/stereo...remot--320-641

          Do you have a soldering iron? Here it is in PE kit form: https://www.parts-express.com/class-...powe--320-6400

          Plusses:
          *Enough power for a set of bookshelf speakers,
          *A real volume knob!!!
          *Remote Control (the leads on the IR receiver can be extended 5-6 inches at least with no problem)
          *USB input for MP3's on flash-drive or to charge phone
          *3.5mm input to connect to laptop audio output
          *One of the built-in EQ settings actually boosts the bass nicely, the rest are rubbish though.
          *The novelty of such big sound coming from such a tiny little board

          Minusses:
          *Supposedly cuts the bass under 70 Hz, but I've not observed that myself.
          *Needs some type of assembly.

          I've used it several times and it's really pretty nifty. No problem with heat either. I really like it, especially for the money.

          Alternatively, this amp is pretty good... https://www.parts-express.com/dayton...5-wpc--300-380
          It will drive a set of Overnight Sensations to very loud levels and has a non-Class D sound to it, warm-ish in other words, pretty nice overall.

          oops, just realized, it doesn't have bluetooth, it can be added easily though.

            +1.

            Dorm room, 5 to 10 W is sufficient. Not in any of the drom rooms I was around in my youth - doesn't seem realistic to me. The 2.1 amp with its 24 V PS will provide 33 W rms into each 8 ohm speaker.. Double that for 4 ohm speakers. Adding a sub down the line will provided added output as well.
