Dual Rythmik F-25 Direct Servo subs - On the way!

Hello all, I just now pulled the trigger on another milestone for my rig. 2 ea. Rythmik Direct Servo sealed subs with dual 15" cones and an 800w plate amps.

http://www.rythmikaudio.com/F25.html

F25_raw.jpg

These will be replacing the 2 Tyler Acoustic subs I got from Trey years ago. I heard a sub at an audio event last year that was hands down the fastest, cleanest, most audio precise sub I had ever had the pleasure of hearing. It was also one of the ugliest subs I have ever seen. After a bit of research and talking to Gary Koh (The owner of Genesis), most all suggestions pointed to Rythmik subs being the best cost to performance ratio of the direct servo subs on the market today.

I read every single thread here at CP and many other threads on other forums regarding anything and everything Rythmik and the general consensus with Rythmik subs was that once folks bought them, they either upgraded to another Rythmik or never sold them. I don't recall anyone having any issues with them at all, just praise....and a lot of that praise suggested the direct servo subs were not a subtle change.

While I don't usually but things for my stereo unheard, I made an exception with these based upon my research and also based upon what I heard with the aforementioned "ugly" sub. I got two of them, so that I can enjoy the lower reproductive effort in stereo. I have been enjoying the subs in stereo for years now with the Tyler's but this (based upon what I heard) should be a significant upgrade to the rig's overall performance. It should even best the Velodyne SMS-1 and VMPS Larger with upgrades setup I had years back. THAT was one dumb decision to get rid of that combo but I wanted to KISS and the SMS-1 was just another non-"needed" component within the chain. This should more than make up for that loss.

Looking forward to the new toys! They will be delivered while my rig is being featured at an audio event up toward Bryson City, NC so they will get plenty of burn in time....although, I don't know if burn in time really relates to subs. We shall see on that one.

Whooooo-Hooo!!! *dances*

    Because to Russ I am a basshead with my single 18" Ultimax in a 4 cubic foot box in the corner, and my 4 x 12 in a 6 cubic sealed box next to the sectional, both running off bridged Crown XLS2000's and their own circuit.....

    If anyone is at or near Bryson City, NC from the 8th through the 17th? Feel free to hit me up. My entire system will be featured at this year's Carverfest.

    While I may not have these subs until Friday or possibly Monday, the 11th, the system without these subs and just using the Tyler's is a treat to experience.

    ES, I gotcha. *winks*

    Subs absolutely burn in... c'mon man, where have you been.

    Those suspensions are super stiff when you first turn them on

    That actually makes sense, Trey. Never really thought about that aspect before but it makes perfect sense.

    If when I get them, they sound better and tighter than the Tyler's (which I am honestly expecting TBH), I'll be happy. If not, I'll keep the Tyler's in the rig for CF and burn them in at my pad.

    Dual F-25's mated with Pass, Magico, etc.....that's just what heavy hitters do! At least those 2 channel audiophiles that have no prejudice against subwoofers in their system.

    That setup is going to be so nice!

    Thanks gentlemen. I found out yesterday that they have been delivered to the cabin office about 7 miles away from the cabins. I drive up there tonight and will pick them up in the am.

    Looking very forward to hearing what they sound like. I hope to the man above that they are as good as the sub I heard last year. That was the "ugly" sub I referred too earlier. That was hands down, the tightest, most powerful, non-locational sub I have ever heard in my travels to date. These two, in theory, should be right up my alley. *prays*

    Will do buddy. He's looking forward to hearing what we have done to the crossovers. His response when he saw the photo of the size of them was funny. Most everyone thinks that the crossover units ARE the subs.

    BTW, the Tyler's will be going up for sale. I need to figure out what I am going to sell them for first.

    How the hell do you pick up 140lb each sub off the ground? :D

    Get help! Don't hurt yourself. Been there. It's not easy for a single person to pick one up unless you are a Bigfoot! lol

    Also, room correction should not be ruled out before there is final say on good bass in a room. Some rooms needs it more than others, Bass is a different beast.

    Like this guy here....plugging the speaker ports, adjusting x-over, and using room correction may have been the different between sending the sub back or awesome tight well integrated bass. Use the tools available if needed audiophiles out there...don't make faces!

    I have now had the LVX12 for about 4 months now and all I can say is WOW! It is so satisfying to now be able to differentiate the many subtleties of those bottom octaves. Not just hear them but feel them as well. It puts a smile on my face every time I fire up my system. Thanks for making such an outstanding product.

    On a side note, I have B&W bookshelf speakers and after running room correction it set the crossover at 80hz. I played with 100hz also but felt that the mid bass did not sound as clean. Then I read an article by Dr. David Rich about integrating ported bookshelf speakers with subwoofers. He found that by plugging the ports he could integrate them better and the sound would be cleaner at the crossover point. I plugged mine and reran room correction and the crossover was set at 100hz. He was right, doing this cleaned this area up tremendously and it allowed the sub to better handle that area of mid bass. I now have fantastically tight bass with the punch I have always wanted.

    Trying this with ported floor standing speakers may also help other customers depending on model.

    I believe per the first line, these are powered subs with 800 watt plate amps driving them.

    Man these look sweet. I am sure they sound incredible!

    Hi, machone. You can take them straight out of the pre-amp or any other variable line level output but I have them hooked up to the R & L loop output of the Musical Fidelity A3CR amplifier.

    Haha! Blew a tweeter today. Guess we were playing the tunes too loud for too long and I cooked the voice coil. I have 4 more voice coils coming our way and should be here Thursday. Whoops!
