Review Price free/subscription

Elsewhere in the line-up is a £269 pair of THX-Dipole rear speakers. Their dipole design means they output sound from both sides of the cabinet, offering a more diffuse, enveloping surround performance than direct radiating speakers. Ideally, they should be mounted on the wall so that sound can radiate along it and make you feel truly surrounded.

The THX-D dipoles - designed to envelope you with audio

The THX-Dipoles feature two reverse-facing silk dome tweeters and a 7in Crystal Fibre woofer, achieving a frequency response from 45Hz up to 22kHz. They also include electronic protection for the tweeters to prevent damage when listening at high volumes. And like all of the speakers in the system, there’s a pair of gold-plated binding posts on the back (the front pair boast two pairs for bi-wiring purposes).

Doubt you'll squeeze the THX-CT centre speaker under your TV!

On crucial dialogue duties is the THX-Centre Speaker (loving Crystal’s imaginative model names) which is THX Select certified and costs £149 when bought separately. It’s acoustically matched to the other speakers in the system and as such features the same Crystal Fibre woofer and free air tweeter. At 550 x 215 x 162mm it’s on the large side, so don’t expect to squeeze it into a tight space under your TV – this is a centre speaker for dedicated cinema rooms only.

The system's THX-12SUB subwoofer is a biggun

The subwoofer of choice is the £399 THX-12SUB, an absolute beast of a bass box that looks loud, never mind how it sounds. Despite its imposing dimensions (441mm high, 470mm deep) and back-breaking weight, the high gloss/black ash works a treat and makes it surprisingly stylish, particularly with the grille fitted. On the back is a volume dial, phase reverse switch and another switch that lets you alternate between THX Select and Variable modes.

On the inside is a mighty 200W amplifier and a 30.5cm long throw driver, which incorporates a light treated paper cone. Its THX Select certification means it’s primed for medium sized rooms up to 2,000 cubic feet in size with a listening distance of 10 to 12 feet from the screen, while its frequency range is quoted at 20 to 350Hz.

Nearly stumping up for a pair of used Linn Komponents... now you throw this under my nose! Arrrrgh!

Ah - my newly purchased Onkyo TX-SR608 only outputs 160w p/ch. Reading the specs of these here: http://www.crystalaudiovideo.c... , is the Onkyo sufficient enough to drive these?

Very tempting! Would be good to know what components you test with, just for reference - amp, source, interconnects, speaker cable? You mention biwiring the fronts is possible - did you do this? Some 7(/9/11).1 amps allow you to repurpose unused inputs to bi-amp the front channel of a 5.1 setup - did you try that?

@Tobeman - yes, you won't have any problems. In fact it is generally considered good practice to have speakers rated to at least the maximum output wattage of your amp - this means the amp should be able to drive the speakers as hard as you like without the speakers being over-driven and introducing distortion, or (worse) blowing their drivers. Trust me, unless you have an absolutely vast listening room, or you are planning a music festival, or you are profoundly deaf, 160W per channel into a decent set of speakers will go hard enough to make your ears bleed.

Nice review about a company with a purpose.

@john mclean - it is better to have the amplifier more powerfull than the speakers, sometimes up to twice the rating, because if the amplifier 'clips' the output will be a square wave and will probably fry your tweeters. speakers are very robust & will take short term peak overlords easily especially if they are meant for sound re-inforcement, i.e. PA use. professional users such as DJ's etc usually have limiters to stop the amplifier being driven into overload and clipping.

@alchobot - I stand corrected. Interesting to know. Still, 160W per channel into a decent set of speakers in a home environment is more than enough to fry your eardrums before you get anywhere close to overloading the amp.

Looks strikingly like an older B&W package! I didn't have much hopes for the centre...

@Tobeman.It is a great combination thanks to THX. My friend uses this Crystal system with Onkyo 3007. With THX and Audyssey processing the sound is amazing both for movies and music.Onkyo 3007 offers 200Watt instead of 160Watt of yours. Taking account that every doubling of power equals 3db, yours TR3007 offers only 1db more maximum power than yours TR 608.The power Difference is calculated in db by 10log(160/200)=0,97db

@poisonjam. I had similar thoughts with you especially because the towers use 2 woofers and the center uses only one. It is probably because towers are designed to meet THX Ultra2 Sound levels and the Crystal THX Center is designed for lower THX Select sound levels. But the main difference according to THX is the lower maximum Sound levels and not the sound quality. According THX both Select and Ultra2 speakers should offer similar response above 80Hz. We know that it is easy to have similar excellent midrange with pure design of 2 drivers, than using 2 woofers, 2 midranges and one tweeter as in most Ultra 2 center speakers. And the small size sometimes is more important than the lower price benefit.

YE im kind off considering these myself, to go with my onkyo nr906 in 7.2 guise of course, centre could be a problem space wise. and why mix the two THX specs.
