Yeah Nick, Am looking for built in bass managament and appreciate the advice about using the sub, but I am such a newby and so busy with my business I'm not motivated right now to try the subby, bass management routine what with running new wiring and all. May try it some day but weird thing about my baby Mirage Omni S8 is that has only one set of high level speaker inputs which seems difficult or impossible with that single set. See page 3 on the manual.

Anyway I'll keep the sub bass management idea in mind for a not so busy weekend and see what I come up with.
This what you need to know when/if you decide to manage the bass. Pretty straigt forward stuff IMO.
Method 2 – Speaker Level – For Music Applications
1. The other way to connect your subwoofer to your receiver is using
a High-Level (#8) (speaker wire) connection. First remove the highlevel
vibration dampeners that are installed between the terminals
and then simply connect the speaker wires from the Front Left and
Right Speaker Outputs on your receiver to the Left and Right Inputs
on the rear of the subwoofer (#8). It is imperative that speaker
polarities be maintained, one must connect the positive and
negative wires to the appropriate positive and negative terminals.
Failure to do so will result in an out of phase connection, severely
limiting the amount of bass in your system.
2. After connecting the High-Level (#8) (speaker wire) between your
receiver and subwoofer, ensure no fray wires are touching, as this
could cause a short circuit and damage your electronics. Plug your
MIRAGE® subwoofer into an AC outlet. Do not use the AC outlet
on the rear of your receiver.
3. See Final System Adjustments, below.
Do NOT connect both RCA (#7) and High-Level (#8) connections
simultaneously, as this will damage your MIRAGE subwoofer.
FINAL SYSTEM ADJUSTMENTS
1. The Subwoofer is equipped with a master power switch which must
be engaged prior to use. After having completed the break-in
process, select the correct position for the Power Mode switch (#6),
either On or Auto depending on your system. The Auto selection
will leave the unit in a self-sensing mode, such that should the unit
sense an audio signal it will turn itself on and then shut down after
several minutes without signal, while in the On position the
subwoofer always remains on. Should the system not be used for
an extensive period of time, it is recommended that the subwoofer
be unplugged from the AC outlet.
2. Adjust the Level Control (#1) on the front panel of your MIRAGE®
subwoofer so that the volume of your subwoofer matches the
overall system volume. This ensures a smooth transition between
the low and high frequencies of your system.
3. Adjust the Frequency Setting (#3) on your MIRAGE® Speakers
subwoofer so that the frequency range of the subwoofer blends
well with that of the front speakers (For use with all settings, except
when in Filter Mode Off). Setting the crossover too low will create
a gap between the frequency response of the front speakers and
that of the subwoofer, while setting the crossover frequency too
high will create a doubling of certain frequencies, making the music
sound boomy. When using small satellite speakers, the appropriate
crossover frequency should be from 95Hz to 120Hz, for the
bookshelf speakers 65Hz to 95Hz and for the large crossover
floorstanding speakers 40Hz to 65Hz.
4 Adjust the Phase control (#4) so that the subwoofer integrates fully
with the rest of your audio system. This control is adjustable to
either 0 degrees or 180 degrees, and ensuring that the subwoofer
operates in phase with the rest of the system is critical, as an out of
phase subwoofer will either sound like it is lacking in bass
performance or that its timing is off. This setting will be
determined by your listening position, the characteristics of your
listening room and its interaction with your MIRAGE® subwoofer.
An out of phase speaker means that the speaker cone is moving
inwards when it should be moving outwards, like the other
speakers in your system, causing cancellations of certain
frequencies. By adjusting the phase control, one can ensure that all
speakers move in the proper direction, at the same time.
5. Steps 2, 3 and 4 might require repeating in order to fine tune your
system. Ensuring the proper blending between the speakers and
the subwoofer is critical to the performance of your system, as a
whole.
