adding "slam" to 2-way speakers?

Rhyno before you lay down the long green, try this simple tweak. Insert the appropriate size vibrapods between your 2 way monitor and stands. This will give a noticeable increase in bass extension among other benefits. I have a second system with PSB 2 way monitors also with 6.5 woofer, although this may seem counter to your instincts, try it you will like the results, Sam

Rhyno Do your Merlins have the BAM module if they don't consider it since this is specifically designed for your speakers by Merlin. There are some VSM with BAM in auction and maybe you could get more info on this from them. Have you tried to change speakers position in the room to emphasize the lower frequencies closer to front wall might improve response... What do you think?

i used to run thiel 3.5's - w/the aid of thiel's active equalizer, thew were +/-2db, down to 20 hz. they still were improved w/a pair of vmps larger subs, crossed over w/a 24db/octave active x-over, at ~90hz. and, i dint need the equalizer anymore. i now run the same sub-crossover system w/a pair of meret re monitirs, w/the x-over point changed to 60hz. it's great! while ewe *are* adding extra electronics to what your monitir sees, if it's a hi-quality x-over, i feel the benefits are outweighed by reducing the stress on teh monitors' woofer. of course, ewe could opt to still run your monitor full-range, & yust x-over the subs.

i have vandy 3a sigs which go clean to 25hz. i added a rel stadium 11 and it made a huge improvement, and i don't notice the sub AT ALL.getting seamless low end extension is'nt easy, but the rel does it.

I have Merlin VSM-SEs in a rather heavily damped room, and I also added a Rel Stadium II. I agree with Marklivia. The Rel does do it, probably with all speakers that roll-off their bottom ends smoothly and cleanly without "burping" or "harrumphing" as they reach their lower limit. That's because according to REL, their speakers work best as bass augmentation, i.e., adding bass that your main speakers running full range just can't produce.
