One of the reasons these speakers are so brilliant, is that they are physically large compared to a bookshelf design - please check dimensions and make sure you are definitely happy with a speaker this size before purchasing.
These floorstanders are supplied with adjustable spikes, which hold the speaker absolutely rigid, giving the best sound. The spikes actually cause LESS damage to carpets than castors or rubber feet, because a spike passes through the carpet pile and leaves no mark. Spikes should still be used on wooden floors - if you are worried about floor damage, simply use spike protector discs (which can be purchased cheaply from Amazon) or even a five pence coin, under each spike.

Q Acoustics Concept 40 speakers
Big brother of award-winning Concept 20 !

Take the award-winning Q Acoustics Concept 20, give it another bass driver, then extend its cabinet down to the floor - and you've got yourself the amazing new Concept 40 !  The Concept 40 retains all the attributes that make the Concept 20 so popular, but also boasts a much deeper bass sound and far more 'presence'.

As with the Concept 20, the Concept 40 employs a radical new type of cabinet construction, to 'damp-out' unwanted resonances, before they can mechanically corrupt the speaker's output. This is achieved by the elegant solution of building a cabinet within a cabinet, the two separated by an ultra-efficient hi-tech damping compound known as 'Gelcore'. The vibrations created within the inner cabinet are therefore mostly filtered out before they can reach the critical outer cabinet and front baffle, where the drive units are mounted. Any remaining resonances are further filtered by the tweeter's de-coupling system.

To understand why all this filtering is so important, it's useful to remember that the whole of the tweeter diaphragm only moves fractions of millimetres to create sound, so any unwanted vibration can have a massive effect on the linearity of that movement. The result of all this Hi-tech wizardry is a speaker that truly dazzles with any type of music, producing the sort of clean, transparent, 'ultra-3D' sound that you would expect from a speaker that is virtually free from unwanted resonance. These speakers are beautifully finished, look fabulous, have excellent binding posts and sound simply sensational !
