Subwoofer Advice

@navyachts "you have 5 subs in your room, with another two on their way?"

I have 5 in the room but the two rears were down firing ported studio because I could not at the time get a front firing that would fit and was balanced.  But recently I have been discussing development of wave forming with Trinnov and front firing would be much better for this so the rear down firing will be replaced by the Norwegian Arendal 1723 subwoofers that are strictly speaking 'side firing' or double side firing.  Are 18.9" H x 13.2" D x 17.7" W.  With a 13.8" driver in a sealed enclosure.   Not as good 'value' as the SVS on $/watt / inch.  But I cannot find a better alternative as I have a 15" depth restriction.  And my son gets two subs for his AV room.

@audio_rd_uk cool!

@OP Integrating subs with all-planar speakers might be a lot easier than with hybrids like the Martin Logans.

Alternatively: 

EDIT: I prefer stereo subs on the inside of your main loudspeakers.

@navyachts

I have a single ML BalenceForce 210 in a substantially bigger room (20x24) than you do and it does the job with my ML CLXs. It might be nice to have a pair for stereo bass, like I had with my Entecs, but it eats up floor space I need.

The Ml BF subs have the advantage of being able to use a ML supplied crossover for your 13As. There are two, one if you want to run the 13As full range, and another if you want to roll them off in the bass. I run my CLXs full range. Then, with the PBK kit and Anthem software, you can create a custom BF output profile that can give you a much flatter in-room bass response. I can’t imagine using a sub that can’t do this. The before and after is night and day.

I don’t know much about their new subs, maybe they do all this for less money. I would call them and also look on the ML forum.

@docknow thanks for the insight, I'll check it out, for sure.
