MERLIN VSM OWNERS WITH SUBS

I am using the VSM M speakers in a large family room that is half underground,three of the walls are concrete with paneling. The Earthquake Super Nova 15 works great with these and offers a lot of tweeking flexibility.These can be found used pretty reasonably. I am using this without the BAM.

perhaps you should give me a call first to go over the set up and jumper situation. i will have certain recommendations that may resolve the issue for you without the purchase of a sub. the super bam mod like spencer suggested is one consideration but i have questions of the setup and where the bam is used and how.

Another consideration is the room dimensions and their impact relative to speaker and seating placement. I apologize if straying too far from the original question, but just trying to help.
In my similarly-sized room, I found that measurements using an inexpensive Radio Shack sound meter and the signals from a test CD allowed me to easily plot out room response(i.e. peaks & dips at various frequencies). Changes in seating and speaker locations as small as 3-6in. made an audible difference. I thought that a larger room would allow for more bass at lowest frequencies, but in fact that wasn't the case. Some spots had pronounced bass dips as much as 10db. By moving seating I was able get smoother and flatter response. The caveat being to keep in mind Bobby's advice on speaker location. Cheers,
Spencer

I seem to remember the local Merlin dealer having success with a line called TBI. You can check these out @ http:www.//musicalsubwoofers.com
