  • Build better than what I have bought.

    I have just retired and I want to build speakers that are better than what I currently own. All are Polk audio. My floor standers are the LSI 15, RTI a7, the Euro model, The t50. Bookshelves include the LSI 9, RTI A3. Monitor 40. Center channel is LSI center and others. Subwoofers are one Polk and two of better brands that I don't recall at the moment. Here's the problem, I have moved in with my 92 year old mother because of her health so my listening room is also my bedroom. The bedroom measures 12 by 15. I have just about every woodworking tool anyone could possibly want but I do not have any skill as of yet. I will just keep building the cabinets until I get it right. My receivers are Yamaha rx v2600, rx v2500 so they are old but I don't care about the latest tech for watching movies. All I care about is music. I would like to eventually end up with a 7.1 surround. The new front speakers could be towers but the rest will need to be bookshelf. I obviously like Polk but I want to build speakers that sound better. My budget (I hope) would be $500 to $600 per pair including paying for a prebuilt crossover. Can I get better than the polks in this price range and if I can, what should I build. Thank You in advance.

    So you know, the LSI 15 were $1600 a pair, LSI 9 were$1200 The RTI a7 were $1000 and the RTI 3 were about $400 a pair so I believe these are pretty could speakers. I hope you guys can prove me wrong.

      There may be some kits available with the x-over assembled at an extra cost. I don't know how good, or bad the Polks sound by comparison to anything though.

        The two American based kit suppliers I'm thinking of will build your crossovers. One of them has many crossover PC boards available. I'm having Meniscus build the crossovers for my Continuums.

      Nothing in the $600 range is going to beat your LSi 15's.

      For $150 I would recommend getting a DSP408 and using it as a 10 band parametric eq between your source and your receiver. You can also time align your sub(s) and your mains. That gives you a tremendous amount of tuning ability.

      Also consider a UMIK measurement microphone and download Room EQ Wizard for free. That will allow you to get your feet wet and try to learn about room measurements for less than a hundred bucks.

      Being defeated is often a temporary condition. Giving up is what makes it permanent.

        I would think some of the smaller Statement family members would be "appropriate" for a 7.1 in a 12x15 room. If you want a coherent sound with the various speakers voiced by the same person using many of the same drivers.

          Thanks Everybody. Ray Tremblay you are suggesting something that I know absolutely know nothing about but learning new things is fun right. I have experimented with Yamahas built in room measuring set up software on my receiver. I think they call it YPOA or something similar. Maybe I know a little more than I think.

            I own a pair of the Lsi15s.
            Not a perfect speaker, but for sure quite respectable.

            The weaknesses I found, are lack of deep bass, a bit too much upper bass (90-140 hz about) and a slightly recessed mid range (1.5-3khz about)

            Otherwise it is quite smooth and very listenable.

            When I eqed it by ear and pink noise +3 or 4 db @ 32 Hz
            -3 or 4 db @ 125 Hz
            +1.5 db around 2 kHz
