What is the most dramatic way of increasing a speaker's Bass and Low mid?

Hi dumbeat,
Stage 3 Concepts. I was lucky and was able to get a free audition from a buddy who had already purchased it. When I knew I was ready to make that commitment, I bought Used for about 50% off MRSP.

From what I read you already have great components. Just need to maximize their operating potential.

I began with one Stage 3 Concepts Kraken from the wall outlet to a Passive Power Strip, back then it was Oyaide R-1.  From that power strip I ran Silver Oval 2 power cables from Analysis Plus to my components.

When I was able to find another Stage 3 Cable, in this case Minotaurs - a step down from Kraken,  I replaced the Analysis Plus Silver Oval 2s with them. I started from the source/ CD player, then the Pre amp, and finally the amps. 

It took several years to source these out and I am still trying to get into a pair of Stage 3 PC for my Subs. I am currently using the last two Analysis Plus Silver Oval 2 on those. Know that with each Upgrade there were remarkable differences.  It takes some patience for sure, but well worth it.

The way I look at it is the investment I have made over the years in Power Delivery has been able to maximize the performance of my components and speakers. This substantial investment has come in at a fraction of the price of what some of my rich friends have spent on full blown out 500K - 800K systems. In some cases twice over.

Naturally I have made comparisons, and I will say that Musically,  my system is just as good if not slightly better than the 500K systems.That assessment is mainly due to personal preferences and choices. When it gets up to the 800K systems - admittedly they are better, but certainly not  90% more $$$ better. Where all these systems really excel  is their commitment to ergonomic design / packaging - Really Sexy looking gear that blows away my stuff. I would give my system  a 6 out of 10 for looks and its probably a bit lower as no parent ever really wants to admit that they have an ugly kid - no matter how talented.

I hope this helps you out
Enjoy the ride, Its not a race..

@rauliruegas:
The Joule amps totally changed the tonal balance and clarity in all freqs. So for now i am getting used to that. Its not to say the Merlins are not seemingly bright speakers, I say seemingly because i think it is a perception built on past experience, but they do not hurt me now as they may have before. Its a journey. I also realize that hearing so clearly can hurt you at first, just like what happens to your eyes when the light is up after a long time in darkness... let the eyes get used to all the detail...;)

How about a lower speaker stand, and then tilting the speakers back?  Lowering a speaker 3-4 inches can reinforce the bass, and also change drastically the frequency of the null you get from floor bounce.  You'll need to tilt them back though, to maintain proper driver alignment from your listening position.  

I highly doubt you're really going to make changes to the speaker themselves and get much of an impact.... improving the room and the surrounding equipment would be where I would start.

For example, what amp are you using? With my previous speakers, my Bel Canto REF500M sounded amazing and when switching speakers, although they never sounded bad, the change to Pass XA60.5 added lots of "flesh" and dimensionality. The lack of bass and mid bass might very well be a mismatch between amp and speakers.

And you're argument for cables... I understand, I work with engineers every single day, but fact is that there are things in life that are not measurable yet perceived as improvements. I think cables and digital transports both fall within this category.

Dear @dumbeat: So, now you are ok with the bass/low mid you were asking for.

Btw, the comparison you did it between the ATC speakers vs the Merlin is not at all a good reference because the Merlin is in reality a two way speaker where the ATC is a 3-way and more important than that is that the ATC are active speakers with dedicated amps for each driver, amps that meets the specific drivers needs. Big difference vs Merlin's.

There are other alternatives to achieve even better quality performance levels from your Merlin's other than the change you made it with the amp but if rigth now problem was fixed the is useless to post about.

Regards and enjoy the MUSIC NOT DISTORTIONS,
