Quad ESL help appreciated!

Can you put them on the right hand wall ?

Can you put them on the right hand wall ?

Unfortunately not as the entrance to the room extends into the room about 3 foot to meet fire regulations so I would be sitting in front of the door . . .

Also corner sofa's have been chosen, bought and assembled to fit the room in that configuration and I'd be getting into serious trouble if I started dismantling that. She's barely recovered from them being in the room at all and occupying the space a TV used to fill . . . not that she liked that much better . . .

Thanks for the suggestion though, appreciated.

Cheers

Only remaining option is a loft conversion

Probably less than what I've spent on these . . . .

I'm not surprised you are getting a boomy dominant bass. Your 57's are far too close to the sloping wall/ceiling. If you can't move them forward by at least a metre then I would suggest experimenting with some sound absorbing material to surpress reflections from the wall/ceiling.

I have a very similar room and have 57's raised on brackets off the wall leading up to sloping roof.
they work well, just 10- 20cm from the wall. I have no absorbing material installed in them .
Another pair below presently sit on their original feet - these need to be raised though about 17cm to meet the
top pair.

So it can be done using 57's effectively without any rear reflection - they do not seem to lose anything with reproduction,
or for that matter gain bass response. If on the other hand I do move them out into the room - and I have tried this
the shape of the room urges you to put them back. I also appreciate they work well located away from boundaries in better
shaped rooms, particularly when raised about 30cm, but rear wall mounting is also quite OK

I would recommend you raise them up about 30cm, above their existing feet and slope them slightly more forward like being straighter,
as this makes a huge difference. Try some suitably dimensioned pieces of wood under the original feet, with the third back leg
about 6cm higher than the front pieces of wood. A slab of wood under each - maybe black would suit the decor, once you have
them sorted with how much height and slope forward.

The picture is a tad misleading, in the dark area behind the speakers there is probably 1.5 meters plus quite a lot of sound absorbing material. There is actually an LP12 (just visible) on top of the rack behind the speakers which has enough clearance to play open lid (just).

I completely agree it's still not ideal and from the top of the speakers working back there is certainly not enough space to let them breath properly and do their thing.

But this is my point, with the un-serviced speakers in this configuration the bass output was such that it was just right for the conditions of the room and the resonance from the rear wall actually helped enforce the light bass. Now that I'm starting with more bass to begin with from the serviced pair its just way too much.

The next pic may give a better perspective but as you suggest Barry it's still probably not enough now that the speakers have higher bass output.

Seeing as I can't really pull them out too much further (I will a bit) the only thing left to try is indeed more absorbing material as you suggest.

I suspect I may just have to accept this is no longer the room for them!

Thanks for your comments.

You can see what I mean about the pitched roof going nearly all the way to the floor now.

Unfortunately this means the speakers only have enough clearance from the rear wall until you get to about half way up the speaker.

Interesting, I will look into this and think about experimentation.

I may come back to you on this when I've had a little experimentation.

Thanks

That looks 'better', but the problem is still the 'trapped' space behind the speakers. This is exacerbated with the right-hand speaker being adjacent to the wall. What kind of absorbing material are you using. I have read of Quad 57s being used in corners each side of a chimney breast, using papier maché egg boxes as absorbing material, stuck to the wall behind the speakers. How close are the speakers to your listening position?

Have you spoken to Quad describing the phenomenon and asking for their advice? The people at Huntingdon are very helpful - give them a call.



My 57s are 2 metres in front of highly reflective patio doors, are adjacent to the side walls and are situated in a 'live' area of the room, but there is no bass bloom.
