I am looking for some thoughts and experience on using sub-woofers in 2 channel stereo - as opposed to home cinema.

I guess, first pitch, on an "if you don't try - you'll never know" basis, is does anyone near to Maidstone have a sub-woofer they consider good that they could lend me to try for a few days?

Otherwise, what are recommendations for good products (I have a £200 Cambridge unit with my home cinema, which is fine for that purpose, but not floating my boat in the stereo)

I have a small room, 4.2mx3.5m with the speakers facing across the 3.5m width, and don't play too loud because we are semi-detached atm.

I tried Kef R700's to get more bass, which they supply, but whilst superficially very appealing, smooth and refined, swapping back to the Ventricals reveals the astonishing mid-range qualities (very, very , very like Quad Electrostatics) which the ventricals have. Whilst bass is probably a bit better than electrostatics, its still not Heavy Metal PA stuff. Hence the desire to blend in some sub-woofer

However, early experiments, before moving the Ventricals out really wide, led to a flattened sound stage. Instead of an expansive arc soaring above the speakers, the sound seemed to come from a 2 ft band running across the top of the speakers and between them. Take the SW out, and the sound stage arcs up again, but there is a tiny longing for a bit more bass. Its better since I moved the Ventricals wide (a lucky accident, due to wanting to compare them with the R700s, deemed too heavy to move, and hence the Ventricals placed outside them - works really well)

Do others get a narrow belt effect with a sub-woofer? (Particularly others using a SW with Quad ESL's). If not, which SW are you using?

Hi Richard,

I don't get any narrowing effect, the sub is an REL Stadium copy, with of course the ESL57s.
I bring it in at 50Hz to just boost the bottom octave.

A few years ago I ran a Audionote otto SE with living voice system and always felt I needed more bottom end so added a REL quake. I got a little improvment but a mate of mine said to try another so I got another on lone from a shop and BAM. I had stunning bass in my system but not at all over blown. I say two smaller subs are far far better than big one in a small roon. Running two never swamped my mids.

Look out for a pair of MJA pro50 of the rel quakes. Get a pair on dem to try in your room first so hear the effect.

Thanks. I think setting the x-over point at 40-50hz helps. I don't fancy hanging the ventricals from the ceiling corners though! I find rels bewildering array of units very confusing. The blurb says they're all great so just get the dearest one? The focus appears to be on window rattling cinema realism whereas I am after tight and controlled. Anyone want a pair of piano black r700s b4 I stick them on fleabay?
