Description

Thorens TD160 with AT95/ paratrace feeds a Bryston BP16 pre, 10B crossover, 4BSST and Harbeth M30s. Subs are B&W ASW750s eq'd via the Behringer Ultracurve. CD transport is Cambridge Audio. PC feeds 96/24 bit audio via fibre-optic, and images via HDMI to TV. Acoustic treatment is minimal, with 3 GIK monster bass traps behind my listening position. The Harbeths sit on squashballs to isolate them from the suspended floor, dramatically improving bass clarity.
The room is small, 5m wide x 4m x 2.4m high. The speakers are against the long wall.

addendum: The RH sub is now fitted with a Hypex FA501 plate amplifier, and the equalisation is now performed with the FA501's built-in DSP. When the LH B&W sub amp blows again, I'll do the same mod.

edit: both subs now have Hypex FA501 and I've binned the Behringer. Oct 2020

How well do your subs handle with being mounted on the wall. Its got me thinking? Does it give a certain vibration feel due to the wall being stud and plasterboard?

The whole point of mounting them on the wall is to stop vibration transfer. My walls are stone and brick built, plaster-finished and are very solid. There is no vibration transfer to the turntable mounted on the same wall. The shelves are fixed with 6 off 14mm / 5/8" expanding steel anchor bolts. As the subs weigh 35Kg (70lbs) each, this setup may not work with a stud / boarded wall.

How was your experience with the elevated subs vs subs on the ground?
Click to expand...
On the ground ( which is a relatively lightweight suspended floor at 1st floor level) the subs shook and vibrated and excited every floor resonance ( of which there are many) . This coloured the sound and every kick drum, string bass , and organ pedal pipe had the same "character".
Lifting the subs off the floor enabled me to equalise them properly without floor resonances confusing REW.
All of this, together with isolating the main speakers on squash balls, cleaned up the LF sound and enables good discrimination between bass sources. 32' organ pipes can now be discriminated from a 16' rank, and you should hear the twin basslines on Lou Reeds "Walk on the wild side" in hires now!
