The Bass Optimization Manager (BOM) is a very high quality fully adjustable 4-pole Linkwitz Transform Function analog bass
It is designed to tailor the bass response of any speaker by adding
an addition 10-20Hz of low bass and tailor the amount of bass from the speaker
to match your rooms acoustics.
You use two of the pots to enter the
"Q" and "Fs" resonance (more or less the -3dB point) of
your speaker. Then, you use the other two pots to dial in your target
additional bass (Q) and output (expressed as boost). The EQ changes
the woofer output from your actual curve to the target curve.

It can go between your amp and preamp, in a tape loop or between a source, like a DAC, and your integrated amp.

The BOM works
with any speaker and can add an extra 10-20Hz of low bass and offers level
adjustment of that bass. Use it with Emerald speakers or any other brand for
improved bass performance.

It is great on monitors to Magnepans.

Superb on Kef LS50's & B&W 805's

The high quality board is extremely transparent as was designed as a high end product. See the photos. Available in black or silver.
