  • High Efficiency Micro Bookshelf Project Idea

    In pursuit of excellence and a fine listening experience I wanted to put forth the following idea for a project.

    Design Goal:
    Create a high efficiency micro bookshelf speaker to be used with a lower power amp such as a Lapai 2020 or tube amp that would be capable for SPL in the 90+ range with exceptional detail and clarity as well as low distortion.

    I found some mid-woofers that might fit the bill and was considering various tweeters such as pro gear bullet and or super tweeters.

    FaitalPRO 4FE35 4" Professional Full-Range Woofer 8 Ohm
    Dayton Audio PA130-8 5" Full Range PA Driver
    Celestion TF0510 5" Professional Midrange Speaker 30W
    Galaxy Audio S5N-8 5" Neodymium Full Range Driver 8 Ohm

    I am not sure how suitable these drivers would be but they all are 90 or higher in sensitivity.

    I think a project like this would have some merit but since I have never designed a speaker before I thought I would throw this idea out and see what the true speaker design guru's thought.

    Your input/help is greatly appreciated!

      You will not get much bass from such a design, physics and stuff.

        Single speaker, coaxial and 2.1 designs always intrigue me.

          I have been playing with WINISD with the FaitalPRO 4FE35 4" Professional Full-Range Woofer and it comes out with a .8 liter vented box tuned to 47.22 Hz. So that would be pretty awesome on a desk in your face. Now if someone could help me with a tweeter and crossover we would be in good shape.

            Efficiency, size, and extension are inherently at odds with each other. I don't want to stop you from experimenting, but you should have reasonable expectations. Give it a shot though, there's no harm in trying, and you'll almost certainly learn something from the attempt.

              Crap pic and zero bass below 100 Hz but they are certainly tiny and get plenty loud. Dayton 5" PA full range and GRS Piezo, cap, resistor, done. Cabs are pretty heavily stuffed and are built with 1/2" MDF, no bracing. With a Topping 25 WPC amp we managed to get to pretty uncomfortable volume levels easily. Overall dimensions are 9"H x 6"W x 5-1/2"D. Probably about 5-6 lbs each.

              They won't win any prizes for SQ but they sound surprisingly good and will rock for a tiny garage stereo. I plan on building a compact PA sub with dual Dayton PA 8's and an SA70 to match.
              Your results may vary.

                MAtt, could you shoot me the cap and resistor you have on them? Thanks!

                  What are your other constraints for the budget and size? Like 90 db at 1w/1m in 4 liters to 50hz under $150 pair, passive?

                          I wasn't really considering budget. I on a personal note am rather thrifty. But what I want is SQ and something that will fit on a desk and not take a lot of space. And I want to be able to turn them up when needed and sound bi*chin.

                            I think that has got to be a typo. I'm pretty sure that is supposed to be cubic ft, since 0.8 L is half the size of my Choti.

                              Ya the FaitalPRO 4FE35 after working winisd comes in at .8L. Seems pretty small to me...
