I wonder... how many people have experienced servo controlled subwoofers? I do mean "experienced". I've heard sealed and an open baffle triple stacked pair of 12" servo subs... it's the best bass I've ever heard. It is not even "just a little bit" better, it is clearly superior. I can't imagine I would ever go back to non-servo tech for bass.
Experience it if you ever get the chance.
Are REL the most Musical Subs?
Forgive me if I have created a redundant thread. I don’t usually post in the Speakers area.
I have a Paradigm sub in my basement HT that has apparently given up the ghost after about 20 years. I’m not a huge bass listener. We used to use the area for movies but lately a different room of the home has taken that over. I listen to classical music and the system gets used primarily for SACD and Blu Ray. No desire for multiple subs. The front speakers are full range, setup is 5.1
I added a REL sub to my 2 channel system a few years ago, an REL, and have been delighted with the results. It doesn’t boom at me. What it does do is add the low level percussion effects that composers such as Mahler, Shostakovich , and modernist composers add to reinforce bass lines. I never realized, for example, how many gentle tympani and gong effects are in Shostakovich Babi Yar symphony.
The REL integrates all of this naturally without calling attention to itself. The Paradigm in the basement never did this but it was an older design and more budget friendly.
So I am inclined to replace the Paradigm with another REL in the basement but was wondering what the current thinking is with subs. I haven’t paid much attention lately and the stuff that I have pulled discusses multiple subs, Atmos, etc, and doesn’t seem to address my needs.
Placement will be different as well. The current sub is placed between the front speakers, and the gear rack is on the other side of the room. 20 years ago I had the energy to bury the cables next to a baseboard heat along the all, after schlepping the sub over the basement testing placement spots,but with advances in DSP I’m now hoping to place the sub next to the rack

Purchased my first servo sub from Jonas Miller and Ken Kreisel at their Wilshire Blvd. store 1978. In 1983 the Velodyne ULD-18 provided more control far less distortion and loop time. Being just over the hill I found their innovations miles ahead then and now and still use two DD Plus. |
Very, very few @jim2. In regard to the servo-feedback subs of Rythmik Audio it is because RA is a direct sales (to consumers) company, so being able to hear a RA sub before purchase takes some work. The same is true for GR Research, with the additional hurdle of that company offering their subs (and loudspeakers) as DIY kits only. I’ve posted here on Audiogon about the Rythmik Audio/GR Research servo-feedback/open baffle/dipole sub (the sub is the result of a collaboration between Rythmik’s Brian Ding and GRR’s Danny Richie) on numerous occasions, and the number of Audiogon participants who have heard that extremely unique sub can probably be counted on one hand.
The world of subwoofers can be divided into three categories:
1- The one-of-a-kind Rythmik Audio/GR Research OB/Dipole Sub. The only people who don’t know how different this sub sounds from all others (including the other models from both company’s) are those who have not heard it. That includes almost everyone reading this. Think about it: servo-feedback control of woofer excursion, dipole propagation (with a plate amp that includes a dipole cancellation compensation circuit), and open baffle sound characteristics. Wow.
2- Another one-of-a-kind sub, the Eminent Technology TWR-17, the world’s only "true" subwoofer. Designed to reproduce only 20Hz down to 1Hz!
3- All other subs.

@squared80 I agree with the sentiment that subs are either good or they aren’t, but for my own taste I find sealed subs with smaller drivers to be more “musical” because they trade peak output for speed and accuracy. it’s why I went with dual SVS SB3000 years ago to replace my B&W sub and the SVS are worlds better. They blended well with my B&W 802D also play extremely well with my 800D2. I can definitely recommend SVS. |
