INSTRUCTIONS FOR MANUALLY INSTALLING FORUM SPM FILES FOR MODELER APPLICATION:


Locate your Modeler installation path. Typically, this should be something like
	C:\Program Files (x86)\Bose\Bose Modeler 6.11

Go to ...\data\speaker_data\Bose
	you should now see subfolders for the various product series

Copy the two FCxxx.bmp files into the 'Images' folder.

Within 'Bose', create a new folder 'Forum'.

Copy the ten SPM files into the new Forum folder.


IMPORTANT NOTES FOR USING THE FORUM SPM FILES:

For each model, separate SPM'S have been created for the three different Passive configurations and the two Biamped configurations:

	Passive (no DSP Speaker EQ)
	Passive DSP (standard fullrange EQ for Passive)
	Passive DSP ExtBass (fullrange EQ for Passive with extended bass response)
	Biamped DSP (standard EQ for Biamped)
	Biamped DSP ExtBass (EQ for Biamped with extended bass response)

Like with other biamped SPM's (e.g. RM, SM, AM), the biamped files require default makeup-gains for the LF driver that need to be adjusted by the user within the Loudspeaker Tab. This gain is required to align the levels of LF and HF drivers for proper summation in the crossover region. So, before applying any loudspeaker gain or EQ, expand the list for the biamped model by clicking the 'Plus' sign and type the respective gain into the Gain field for the LF driver. The default gains are:

	FC108 Biamped DSP (LF):			 8.1 dB
	FC108 Biamped DSP ExtBass (LF):	11.1 dB
	FC112 Biamped DSP (LF):			 5.2 dB
	FC112 Biamped DSP ExtBass (LF):	 8.5 dB

You may then apply any Gain in the field for the complete speaker for level adjustment or apply any EQ (at driver level) for equalization.


Note that only the biamped spm versions guarantee that - independent of any equalization applied - the maximum power handling of the respective drivers cannot be exceeded. This behavior is also identical to legacy biamped speakers like RM, SM and AM. Especially if you use the EQ section to manually adjust the signal spectrum from Pink to Speech, it is mandatory to use the biamped spm files.

For the passive SPM's, the maximum power handling is defined as the sum of the LF and HF continuous power ratings, that is 172.5 watts for the 108 and 345 watts for the 112.

As usual, the SPM speaker data is defined for Continuous (LEQ/RMS) SPL. For Forum speakers, assuming sufficient peak power is available from the selected amplifier, Peak SPL up to 9 dB higher than RMS SPL can be expected (without considering power compression). As an example, if you want to predict maximum LEQ SPL for a signal with 12 dB crest factor, you need to subtract 12-9 = 3 dB from the predicted SPL.
