Living with the REL....... ten days on

Posted by: i am simon 2 on 14 January 2004

The REL Quake I got for my birthday has settled down and I find that I am making less and less changes to the crossover point and gain controls.

The sub is set up in the main stereo and also for HT.

Home Theatre seems easier to setup as you almost want the LFE not to be subtle, and the tiny box that is the quake can make some terrifying noises.

Watching Top Gun the other day, the rumble you get from the jet engines is great fun, and explosions have an added dimension.

On to the HiFi

Connected to the speaker end of the speaker cables via the high level input it took quite a few days to get right.

I am now at a stage where I cross over at about 30 HZ and have the gain set surprisingly low. Once I spent a little more time on positioning the sub (small adjustments close to the corner of the room make a big difference to perceived output) the gain could be lowered and I began to achieve the "room pressurisation" that REL describe. At these frequencies that are not so much heard but felt, I think getting the room loading is very important.

The outcome - Normal music that is not bass heavy just sounds more open and is delivered with more confidence. Lower mid bass is not noticeably affected as I think the sub has rolled of up at these frequencies, lower bass is enhanced, but all frequencies seem opened up. Sound stage is improved as well. On deep bass heavy music I am now getting frequencies that the Minstrels did not even try to produce.

Timing and rhythm - I was worried that the sub would not be ale to keep pace with the fast Minstrels and their first order crossover that deliver lightning fast and coherent music, but it seems that in its own domain ie sub bass, the Quake is plenty fast enough and PRAT is not upset to any degree. Please note that if you have the crossover on the REL set too high you run the risk of killing the timing. The fact that the quake is a 200mm driver in a small sealed box probably meant that if any sub was going to be fast enough for the Naim Royd combination then this was the one.

Overall - For a small modestly priced "sub base system" the REL Quake does everything I want and need it to do in the home cinema setup and as a bonus adds a new dimension to the hifi, which may well put off a speaker upgrade for some time.

If the bigger RELs are this quick they must be frightening.

The strangest thing that I have noticed is when the stereo is on and I am not in my lounge, my hallway leading into the lounge has become a giant transmission line for the enclosure that is my lounge and you get the boomiest bass in the rest of the flat, out of all proportion to the volume of the music, however once in the lounge this effect is undetectable.

I would recommend at least a home demo to anyone who likes their speakers but would like them to sound as if they were twice the size, it may save you a costly upgrade.

Simon,

If you haven't already tried it, go down to B&Q, buy yourself a £1.50 concrete paving slab and bluetak your Quake onto the top.
I found it made a big difference to improving the timing of my REL unit.
After all, if you don't like it, £1.50 is hardly a big loss, and you can always stick it in the garden somewhere.

have you fiddled with the positioning much? I know REL say in a corner behind the speakers, but that wouldn't suit the look of my room.

My REL Quake is half way down a side wall away from the main speakers and works fine. It is easier to setup as the bass seems to tighten up a bit and get drier moving it away from the room corner, which suits music well.
You can basically compromise placement to suit your room without trashing the peformance, especially since you have a lot more amp power than you need on the speaker level input on the REL's. It just gets a bit lighter away from the corner.

Mr Sukebe - The Quake was bluetaced on all corners to start with but on a forum recomendation it now stands on three naked feet and one little bit of bluetac to stop it wobling and moving around on its own. I think a paving slap would not co down too well (WAF), but the sub is in wood floor laid onto concrete so it is probably ok, maybe i will try a slba when she goes out for the day.

Doc - I have only used it in the corner but id did experiment moving in and ot from the corner until i got the point where the sub "plays the room". A side wall would be in the way a bit in my lounge.

Geoff - I think in m room to get the realy deep base out of the little quake, I need the room loading achieved by corner placement. In a smaller room or with one of the larger RELs I should think placement becomes less important.
