Subs with CR 1

[dafos]

Joe, I noted that you've mated two f 113 subs to your TAD CR 1. Just wondering what crossover frequency you chose, what's your volume setting on the subs and are you using the CR 1's full range? Also, did you start with two subs? I'm curious since I've been auditioning a single f 113 mated to my Magico Mini with pretty amazing results.

Hi,

I have the subs but I am not using them. I had them hooked up with my Nola Micros and crossed over very low. Since getting the CR-1's, I don't feel the need to use them. I may eventually hook them up, but it will not be for a while.

I DO use subs with my CR1's. Dual REL G1's, crossed over at 20Hz (it does not have a very steep dropoff), volume setting is 3 on both.

The subs really are not essential with the CR1's, I mainly get more of the deep deep visceral bass which I love . Blended with the CR1's through use of a microphone and REW, system goes flat down to 15Hz.

Wow! How did you manage to get down flat to 15Hz with subs that are rated above 20Hz -6dB in room? Do share

My room is 11 meters long and I still get an approximate 4dB dip at 25Hz.

Jack, ratings are one thing... measurements another .

Subs, speakers, and both, you can guess which is which...

 

[JackD201]

I don't doubt that you did it, I'm asking how. If you don't mind that is

 

[AudioExplorations]

Jack, no idea, just plugged them in and down to 15hz they go!

Looks like a bit of room gain bump, or maybe just su placement. What preamp/AVR? Any room correction/treatment? That is pretty flat for in-room response, nice going!

 

[AudioExplorations]

Thanks . No preamp or bass trapping, just panels on the side walls (graph is @ 1/3 octave smoothing). I do correct the 5 peaks up to 300Hz with parametric EQ ahead of A/D conversion (within Pure Music on the macmini), but the measurement is without EQ - I wouldn't be able to live without digital EQ! This is the smoothest I could get these speakers in this room after many many trails.

How do you connect the subs to the DAC? do you use Y-adapters?

 

[AudioExplorations]

Subs are connected to the power amp terminals, a feature of REL subs they called 'high level input' and they recommend for 2-channel stereo use. Allows better blending as the subs take on more of the sonic character of the system.

I'd rather be lucky than good! Although the good do tend to be luckier more often! Good job man.

Room gain

Getting to 15 ok, flat to 15....... really lucky. The room would have to have some sort of alignment of the stars in terms of physical properties.
