Just received my new RM30s with the Xperimental upgrade I call the SR71 package.  

Out of the box impressions, slightly subdued on the highend, with effortless SPLs.

Also there is a great midrange "BODY" that is rich and smooth.

Imaging and depth are pretty good, but not quite as sharp yet, since I haven't played with the pots at all.

Putty is pre-pinched by Big B, and seems perfect already (he uses the Son of AMpzilla also)

For anyone who has requested better upper and midbass impact, my RM30s have both the Megawoofer upgrade and the SR71 and I may have to put more padding in my listening chair, the impact is so strong.

It may even be too much, but we'll see after I burn them in and then kick in the after burner.  Also since they are running "full range" I need to paly with the "blending" frequency of the LARGERs, which right now sounds right since I lowered it to around 40ish.

I have the 10" woofers facing in and the LARGER Subs spaced well apart (using all of each 8' speaker cable) and the bass which started out a little sloppy and boomy is already surpassing (by far) what I had before.

I haven't even placed the "weights" on the cabinets yet to tighten the bass even further.

Only have 2 good hours on them, and about 2 more hours of tweaking and set up.

This system right now is like a mini-Super Tower system with the Largers sitting up on their ends like short bass towers "flanking" the RM30 mini-towers.

I'll try and light them up a bit tomorrow.

How much weight are you thinking of putting on each cabinet?

Enjoy the new speakers John.

Hi John

Any clues as to what this upgrade consists of?

John,
You just blow my mind.  I love my 626's and have oggled the RM30's.  I would have bought them if they had been available.  Good luck.  I think I will start a pool, on how long you have this strain of VMPS, before upgraditis befalls you    
Have fun

Enjoy John!

Hi KJ,

I had around 75# on each 626R.  It will probably be the same.

I use rubber coated (not plastic coated ) dumbbells, or barbell plates.

Another thing I did (or didn't do actually) is I didn't put the flat base on the bottom.

This puts the "slot base" directly on the carpet for a "MUCH BETTER" mechanical coupling to the floor.  With the energy these put out the reactive forces are great and I like a sharper edge and detail to the upper/mid bass.

It also lowers the FST about an inch, which is good since I sit a little low.

John,

You really missed your calling...you should be in marketing!!

Enjoy the new speakers.

Thanks for all the "well wishes".  

Ya gotta love new speakers

Jose,

As far as the SR-71 option, it is still not officially on the menu.  B, is looking to make sure he has the best components and application.  He also needs to set a price for the possible upgrade and how to handle upgrades in the feild.

So right now I still can't disclose it, other than to say, I hope we can offer it.

Woodsea,

Well I had the 626Rs for well over a year, which is a long time considering, I intended to get a "big" speaker again, after selling my RM40s over two years ago.

I think I rang about as much performance out of those 626R's as you can get.  They sounded incredible and in my room the recent soundstage and imaging was the best I have heard.

These RM30's seem to offer an incredible amount of performance and are very well rounded, in that with the "IMPACT" these things have they are also incredible HT speakers.

In my room which is 20 x 30 x 9 and open to a large hallway and kitchen, I needed a "slightly" bigger speaker, if I really wanted to "play it loud".

The 626R, was surprising in this aspect, especially when I ran it through the x-over and high passed everything above 65Hz to it.

Having heard the RM30 many times, it is still "different" to hear it in "your room".

It has also allowed me to move the front LARGER's to a spot that 'exactly opposes' the rear LARGER's.  (since I used the LARGERs as "stands" for the 626Rs they were "closer" together in the front.

I think this has a nice effect too (or so far it seems)

Just waiting for my upstairs neighbors to get out of bed, to continue the "burn in".

Since the damping has changed so much in the SR71  upgrade you can experiment with removing some fiberglass from the enclosure to tune it to you taste.  The putty is well-pinched.

As previously mentioned, every production pair of floorstanders is now taken to my soundroom (a 30 minute rountrip), set up, tuned and has its crossover individually micro adjusted, thus taking care of driver variations too small to measure and leaving little tuning for the home user to do.  I was able to check the efficacy of the "pre-tuning" this week when I visited a new RM30 owner in his tiny condominium (12x14', with a TV inbetween the speakers).  Using a Marantz 8500 receiver and a Denon DVD player as a source, I found it necessary to remove only the tiniest scraping from the PR (about 1/32" around) and make no change of the level controls for optimum sound.  

We have also increased factory burnin to 48 hrs minimum.  As a result of these new measures 95% of full performance should be achieved from the RM series speakers right out of the box.  Subwoofers with the builtin 1000W amp receive the same pre-treatment.

BC, that is going to make it a lot easier for some of your customers.

I know it must have been posted but what exactly is the SR71 upgrade and by "upgraded megawoofer option," is that the standard megawoofer upgrade that has always been available?

Hi Joe,

Yes, the MegaWoofs are as we always have had.

B, hasn't given me a price for this option/upgrade, since he hasn't computed component material and sources yet.

So the actual upgrade is only teaser right now, although some have guessed it correctly.

My biggest hint was early on, when I said it, (like its namesake the SR-71 Blackbird) had to do with the "sound barrier".

 ..

As an "update", I just found out why the high freeks were slightly subdued.

It turns out that the "bi-wired" cable I have is "mis-marked" as to the HF and LF leads.

I reversed them and "NOW"  we have our detail and hf back in the proportion I expected.

Also, I just ordered another "internal tweak" to try out.  Will report when it arrives and I get a chance to install.

Any pics allowed, or is this all "hush hush"?

Hi Grub,

No Pics yet, since it is still being tested at the "SkunkWorks"

[KJ]

Been a while John.  What's the scoop?

B, is waiting for the supplier to give him materials costs, so we can "price" it for all models.

[Marbles]

Would this be Black Hole #5 or a similar product?
