Merlin VSM-M and Bass


A bit of background:

Equipment:
Marantz SA-14 SACD player
Sonic Frontier Line 2SE preamp
Belles 150A Hotrod amp
Merlin VSM-M with BBAM

Setup and room:
diagonal placement
speakers about 5-6' apart and fairly close to the side walls in a 20'x20'x10' sloped ceiling room with a big opening into a 20'x12'x8' kitchen

I bought the Merlin's (VSM-SE) about 2 months ago and had Bobby upgrade them to the Millenium w/ BBAM. My question is how can I get more bass from them? These speakers are (were?) going to replace my Revel F30. The Revel's have the bass that I'm looking for, however, from maybe 100Hz on up, the Merlin's are much better. I just do not get the bottom end that the Revel's put out.

Integrate a sub? And if so, any suggestions?

Thank you,

That's a big room. I would take out the BAM and get a Rel sub. You'll never integrate a sub using the BAM. Of course, you can try it with and without BAM. My 2 cents!
Hi David,
You must use the BAM to get get a proper integration of the sub to the VSM. The BAM offers a steep cut at 30 Hz which you will cross the sub into at 12 or 24 dB (your choice). The 12 dB peroctave slope will result in more overlap at the crossover point so the sound will be fuller in your large room. This may be preferable to you.
Without the BAM, there is no chance of summing the sub and VSM outputs correctly. Crossing the sub above 30 Hz will unweight the wonderful tonal balance of the VSM M so I do not recommend this either. Some experimentation will be necessary for you to dial this in but this is your easiest path and least expensive path.
In a purist sense, your wires (Beldon) and pre offer up a presentation that is somewhat stipped in the bass. This lack of fullness is more obvious because of the VSM's high degree of resolution. Going this route will cost more but will probably make you much more happy in the end. The speakers have a really big bass but you need the associated equipment to be tonally neutral enough to be able to perceive this.
Hope that I have helped.

Bobby,

Thank you for the incredible customer support. Just a note to fellow Audiogon members, Bobby and I had a long talk about the bass issue that I have in my room and he took the time to tell me more in detail the advice he has given above. Outstanding service.
i successfully used a passive x-over provided by TG audio to roll the VSMs off at @ 100hz (first order if memory serves) and let the subs i was using (entec LF20s) run full range (natural roll off @ 100hz).

when i had both TG audio and BFS revier MGDwulf over, both thought it was seamless. and it was good enough for me. this may work for you as well...but get a damn good x-over to roll off the mains (its a passive RCA input x-over similar to the ones available via audioc.com, but using MUCH better parts)...
