Hey Peter or whomever may help.
I just added a mbm12 to my Vtf ho w turbo.
Now i need to get everything setup to tear the house down.
I have only gotten my ho setup to where i was happy with it about a week ago as per Dr hsu's emails,the main thing we changed was putting the ho into a little "under the stairs"utility room in the front right corner of my room,by doing this i got to drop the ho gain from about 2 oclock to 11 o clock with still more low end.
Well now ive added the mbm behind the couch and recalibrated and messed up everything ,so here i go again.
Ive got the ho xover switched to "in"set at 50 hz,the mbm xover switched to "in set at 100 hz and the receiver xover set at 100 hz.
I set the volumes with the subs gain at about 11 oclock on both,using your spreadsheet i found online and the radio shack spl ,the subs checked one at a time then together.subs are set at about 85-89db compared to 75db on all other speakers.
One question,when setting the speaker volumes(fronts ,center ,etc)ive always just went to the front left for example then turned up the receiver volume until speaker is at75 db,then set everything else to match.
Then im at approx.-20 to -30 (volume on receiver)when watching movies.
Speakers are set at approx.+5 to +8 db to acheive 75db.
If i were to turn the receiver volume to say zero and then calibrate all speakers to 75 db (this im sure would have me setting speakers in the -10 to 20 db range)would this make any difference in the overall "blending of speakers and subs?"
Sorry for the long post but im back to serching for the "chest thump" i want from the mbm.I do now have the "shake the house" lowend that Dr hsu helped me find a couple of weeks ago.
Ive included a rather cheesy if not less than impressive diagram of my ht room.Overall dimension of room is 23x 23 plus utility room and stairwell,8 foot ceiling.
This room is a basement room on slab foundation with concrete block walls covered in tonque in groove pine,no drywall,no windows,drapes or wall hangings,i know i need to do the room treatment,bass trap thing but im not there yet.My lack of "bass slam"is do im sure to the room not equipment but is there anything you see that you would suggest changing?
