NUMERAR Loudspeakers





DIY Open Baffle speakers

Materials: NUMERAR Oak countertop

Description: This loudspeaker is simply made of NUMERAR countertops 126 x 62 cm with 38 mm thickness.

My speakers were cut with a CNC router. It is also possible to make it with a hand held router. The stand is fixed with screws. They are 55 cm on the widest and 120 cm high.

The concept is Open Baffle loudspeakers. It has no box. And that’s the genius. Almost all loudspeakers have more or less a “boxy sound”. Even those who cost +10.000$. An open baffle gives an open sound. Very open. The downside is that you need at least twice as big woofers to achieve the same amount of bass. They deliver bass down to 35-40hz, not like a subwoofer, but still with punch and slam that few other speakers can compete with.

This is not so common in the commercial market. Some manufacturers have products like this and they are very expensive. For example, Jamo.

The drivers is from Eminence and Tang Band. You also need to design a crossover.

As a hifi freak i am very satisfied with this solution. 3 pcs of IKEA NUMERAR countertops. High quality bass, midrange and tweeter drivers. A diy crossover. And voila, app 1700$ in parts and I got 95% of the sound of a 17.000$ speaker (compared to Norwegian prices)

    A nice work! I like your woodworking.
    For an open baffle deaign, is the baffle too small to produce deep bass?

    For å dra det hele litt lenger synes jeg du skulle fått en som er flink til med utskjæringer til å gjøre noe kreativt med platene.. Ble nesten litt for enkle vel?

    Sett bort fra det skulle jeg gjerne likt å høre dem!

    Can you provide more information about speakers and crossover? And does baffle shape makes difference for the sound quality?

    Hi
    In this thread you can see specs of the drivers and measure of the baffle: http://www.hifisentralen.no/forumet/diy-og-utvikling-ha-yttalere-forsterkere-etc/55401-ob-prosjekt-2-x-eminence-15-tang-band-8-fulltone-og-ba-nddiskant.html

    Regarding the filter you must have a “space” between the high and low pass. The reason is that the open baffle makes a peak. Usually up to one octave is ok.

    F ex low pass for the bass 100 hz and high pass for the tweeter 200 hz. A simple 12 db Linkwitz Riley filter is sufficient.
    For more Q you can email me at “hel at relekta dot no”
