Don't they all sound boomy?
Some certainly do. But not a REL. There is no black magic in why a REL always sounds clean and controlled. The REL Active Bass Controller (ABC) allows the user to carefully control the sub-bass system output and to tune it to integrate with the existing main system.
Another important factor is the way REL sub-bass systems are engineered. Careful design of high quality components means the sound from a REL is always controlled and has great extension to well below audibility. The best is never the cheapest, but listening pleasure remains long after the price is forgotten. When all is considered, a REL is exceptionally good value. There are many much more expensive subs that do not offer the performance of a REL.
Don't sub bass systems always sound slow?
Some certainly do. Any device that stores energy (including some rooms) will subjectively appear to slow the tempo of the music. REL sub-bass systems use optimum damping within strongly braced enclosures together with large magnet/cast chassis drivers, which offer a superb transient performance. Great care has been taken over all aspects of the design to ensure a "quick" tuneful bass. There is no point in choosing a superb sounding main system only to ruin its sound with a mediocre sub-bass system. Many sub-bass system manufacturers are happy to sell a system that relies on passive components between your power amp and your main system. This will result in poor performance.
A sub bass system is no good to anyone with a small listening room?
It was this aspect of bass reproduction that started Richard Lord’s quest for a solution. The REL ABC will ensure that the sub-bass system matches your room. It drives your room at below its lowest eigentone (the lowest frequency affected by your room). By simple adjustment of the ABC it is easily and quickly possible to ensure that there is no "room boom" (the usual consequence of using any speaker with an extended bass response in a small room).
Are two sub bass systems better than one?
Two sub-bass systems are generally thought to produce a more even and controlled bass response in-room. The best way to find out is to listen to a single system and then add another in your own home. Two subs almost certainly would be better if you listen at higher volumes. However, one REL sub-bass system is the best way to begin to enjoy the bass from your system. The advice to anyone on a budget would be to buy a single system and then add another when you think you need it.
Would two sub bass systems sound too loud in my smallish home cinema?
Two sub-bass systems (running at half the volume) would sound just as loud as one. With two you reduce directionality and gain better control/headroom at high sound pressure levels.
Where should I position two sub bass systems?
The first position to try would be in the corners next to the main left and right speakers (This is the recommended position, which is explained in the set up guide in the user manual and on the REL website). However, if space at the front is tight, (and your other speakers are close together), having two sub-bass systems may make things sound too ‘muddy’. Putting a second behind your listening position should work, but because every room is different, the importance of experimentation cannot be underestimated - evaluate all your options and use what sounds best.
What is the Neutrik Speakon plug pin configuration?
The Neutrik Speakon plug pin configuration is as follows:-
The pins in the Neutrik Speakon plug are numbered 1+, 2+, 1- and 2-
1+ connects to the right hand speaker red terminal at rear of amplifier or speaker
2+ connects to the left hand speaker red terminal at rear of amplifier or speaker
1- or 2- connects to either right or left speaker black terminal at rear of amplifier or speaker
Can high and low level inputs be used simultaneously?
Yes, all Rel sub bass systems are designed to use high and low level inputs simultaneously if required. Both high and low inputs have independent gain controls.
