Thinking of adding a sub---maybe not?


Looking for some advice. I'm thinking of adding a sub to my system and the one I'm considering is the REL T7. I've had subs (Canton) in the past with my older systems but it's been many years since then. My system today consists of a Luxman 505UXii integrated amp, a Marantz ND 8006 CDP/streamer, Dynaudio S40s and a pair of Tekton Lore Reference--I alternate the S40s and Lores through speaker A/B on the Luxman. My room is about 16 x 25. I love my system but after having subs in the past and getting the bass 'punch' from the subs, I'm debating whether I should go that route again. I've tried the loudness button on the Luxman but it just doesn't give the same results as a sub would IMO. Thanks in advance.

Using Loudness ’Backwards’

I’ve always said it was Mis-named, you are not alone in misunderstanding ’Loudness’. It should be called ’Low Volume Boost’, or something.

The ’Loudness’ is specifically for LOW Volume Listening. ON at normal listening level will produce exaggerated muddy sounding bass, and boost highs you may or may not be aware of.

Loudness is to correct output to correspond with our hearing system’s variations as volume reduces.

IF you are turning loudness on, then it indicates you want more bass at normal listening levels, thus yes, get thee some subs. Then, even with subs, at low volume listening (assuming the subs are properly matched for normal volume), you would use the loudness feature.

I have 15" woofers, consider them a pair of directional subs. Bass may start mono in your space, i.e. 40hz fundamental, but it becomes directional by way of the overtones of ANY fundamental note, thus you get reducing volume, but increasing directionality from the overtones, i.e. 40/80/160/320 ...

therefore, I recommend a pair of self-powered subs, front firing, located adjacent to main L & R for cohesive directionality. Once you know where the bass player is, from upper bass notes, even if full mono, your brain will ’keep’ the directionality, imaging will be improved by reality and rememberance.

No ports, or front facing ports if you must.



Having just sold a Rel t7 i would say its just ok.its down firing which im not a fan of..stereo subs are always better with most speakers.  I. would suggest selling the Tektons as i think they are junk garbage  ,adding those funds and buying the new T7x or (2) t5x subs.
Absolutely add subs!!!  Rather than the T7, for a little less you can have two SVS SB1000 Pro subs, and two subs are significantly better than one especially for music IMHO.  And SVS offers a very generous truly risk-free trial period and great customer service, so if for some reason they don’t work out just return them and you’re out nothing.  My experience, once you have a pair of subs properly dialed in you’ll not only have better bass but also a significantly expanded soundstage such that when you turn the subs off the whole presentation collapses and you won’t wanna listen without them anymore.  Anyway, just my $0.02 FWIW, and best of luck.
