Rm1000 in parallel with RTIa5

specd_out

This is just a hypothetical question. Would running a rm1000 in line with my Rtia5s help with some lower freq?

My dad has a rm3000 just chillin in boxes. I have my a5's connected to a Carver m1.0t so I have more then enough power to properly drive them. They sound good but on certain songs I wonder if I am missing something. Would it even be worth my time to connect it up?

Well I connected it up. The damn thing is butter smooth, not boomy at all. Much better for 2ish channel music then my DSW600. So far it seems to blend well. I cannot locate it with the lower freq. I tend to like smooth rolling bass, rather then hard thumping bass and so far it seems to extend my a5s a little lower. So far I have played a few different types of music, Billy Joel - Songs In The Attic on LP, Pink Floyd Animals on LP, Alice In Chains Unplugged CD, Mad Season Above CD, Days Of The New (Green Album) on CD.


My biggest concern is the overlap between the RM1000 and my a5's. From what I read the Rm1000 can get up to 200hz. Obviously my a5's will reproduce that freq.
The main reason I was doing this is because I wanted some more lows when listening to records and cds off of my Carvers. I really like the A7s but I have heard the mids are kinda lacking. So I figured something like this or a small 8" sub might help out the a5s.

I am running this in parallel so basically its another 8 ohm speaker on each channel wired directly to the amp. If I am not mistaken that drops my impedance to 4 ohms. Correct me if I am wrong

Is there something I should be listening for to hear the overlap?

Is there anyone that might be able to help me understand How to best extend my lower freq, and what to listen for when freq overlap. I have tried numerous searches on here and google. Not really finding what I am looking for.

With the Rm sub in the mix, your already overlapping. Your problem is most likely in the setup of the receiver. The A5 with the DSW should cover enough freq. to please most. I would personally take the RM out of the mix and adjust the crossover in the avr, making sure that the one on the sub is turned to the highest value to make sure you don't have a double filtering effect. Have you run the calibration ? Tweeked any other setting like channel levels,etc. ?

Now, you can also hook up the A5's to the DSW that way to see which sounds better. In which case you'd use the crossover on the sub and not the receiver. You'd then set subwoofer to none, A5's to large.

Incidently, you can send double bass to the sub and the A5's too, make sure they are set to large and in your setup menu their should be an option for sub + mains.

Not quite sure what your trying to accomplish here. You say you don't like thumping bass, but want more low end. To me that means you want more mid bass, and that means adjusting your settings to let the sub handle more of it. Raise your crossover freq by small increments at a time, play a track of music your very familiar with, and see if that helps some. You may also have some placement issues as well with the sub so experiment a tad with that as best you can.

Thanks for your advice. A lot of what you said I have done. Including the calibration with the Mcacc, Crossover adjustments, and the double bass (sub plus in Mcacc) It works fantastic on bluray concerts and movies.

The problem I am causing my self is that I also use the Carvers with out the AVR. For example my cd player, and turntable are directly connected to my C-1. My DSW is on the other side of the room so its not possible to run with the carvers, only the AVR. Not to mention its a 12 and is not that great with music.

The plan is to improve the sound on the turntable and cd player. I borrowed the Rm1000 from my dad to try out, but the more I listen the more I think getting a small sub like the psw111 might be a better option. When I look at the specs of the psw111. It specs out at 38Hz-250Hz with a lower -3db of 42. My towers have a lower -3db of 40. I know that my towers rating needs to be taking with a large dose of salt. But would I have the same bass issue with the psw111 as I do with the rm1000?

I would think so. Have you tried just using the pioneer with the carver amp for 2 channel taking the C1 out of the equation ? Sometimes simpler is better.

So no sub is in the mix for 2 channel the way you have it set up, then thats understandable why your feeling a lack of low end. I would just use the pioneer, plus the receiver will give you more options to taylor your sound. Check where your speaker levels are at too, if the fronts are set at something like -4 or greater that may muffle the sound a bit.
