SpeakerFilters Can Measure Your Speakers for Linn "SPACE" Room Optimisation

Linn publish a list of speakers that are compatible with their SPACE Optimisation technology which helps to take the effect of the room from your listening experience.  To take advantage of this, you can select these speakers from a list with the Konfig software used to configure your Linn DS or DSM.

SpeakerFilters has worked with a number of clients to add their speakers to the list available from Linn.  If your speakers are not on the list from Linn, reach out to speaker filters and we can work to have them published for you.  Contact us via design@speakerfilters.com

Mission 783 Aerogel Floorstanders 1999 to 2004 Exakt Filters Added to the Catalogue

SpeakerFilters are pleased to announce a new addition to the range of available filters.

Coming from Cambridge company Mission, the 783 floorstander is a sophisticated 3-way design. Internally the walls of the extremely heavy cabinet feature complex machining to break up standing waves and a side firing bass driver (which rolls of at a low 110Hz) brings the benefit of a larger driver to a slim cabinet.

We're very pleased to add this speaker to the SpeakerFilters portfolio.  Bringing the opportunity to apply Linn Exakt advantages to those who want to get the best out of their Mission 783 speakers.  The filters are available to 783 users "off the shelf" right now.

For those of you without Exakt, but with a Linn DS or DSM streamer, the work completed by SpeakerFilters allows you to enjoy the benefits of SPACE Optimisation with the 783 in its passive form.

Get in touch!  design@speakerfilters.com

Every SpeakerFilters set of filters comes with a no cost 2 week trial period.  We also offer physical conversion of your speakers.




Please note that early versions of these speakers were fitted with Keraform mid-bass drivers which suffered from ferrofluid leakage and subsequent failure.  The SpeakerFilters Exakt filters are designed using the later Aerogel mid-bass driver which is reliable and is said to sonically outperform the original driver.  The Keraform driver is a pale dull grey, the Aerogel is glossy mid blue in appearance.  The Exakt design assumes that the speakers will be positioned with the bass drivers facing inwards.

Linn Keltik with Hiquphon OW1 Tweeter Added To The SpeakerFilters Exakt Catalogue

SpeakerFilters are pleased to announce a new addition to the range of available Exakt filters.

The Linn Keltik was the company's top of the range speaker in the 1990s and early 2000s - specifically designed to run active and a very capable flagship speaker. Occasionally drivers fail or are damaged  - with Linn unable to supply the 015 nor 038 speakers any longer, many users have fitted the Hiquphon OW1 tweeter as a replacement. This means that the Exakt filters from Linn are no longer suitable with this modification.

So we're very pleased to add this popular modification of the Keltik to the SpeakerFilters portfolio.  Bringing the opportunity to apply Linn Exakt advantages more accurately for those who have replaced their tweeters.

These filters are available now at £125 a pair.

Mission 780 Aerogel Standmounts Added to the SpeakerFilters Catalogue

SpeakerFilters are pleased to announce a new addition to the range of available filters.

A multi-award winning loudspeaker from Cambridge company Mission, the 780 standmount is a giant killer from the turn of the century.  It won the Best Stereo Speaker award from What Hifi in 2000 and 2001, along with product of the year.  It's also included in the magazine's Best Stereo Speakers of the 21st Century "hall of fame".

So we're very pleased to add this rather special speaker to the SpeakerFilters portfolio.  Bringing the opportunity to apply Linn Exakt advantages to those who want to get the best out of their Mission 780 speakers.  The filters are available to 780 users "off the shelf" right now.

Naim SL2 Exakt Filters Now Available

SpeakerFilters are pleased to announce a new addition to the range of available filters.

A legendary loudspeaker from Salisbury company Naim, the SL2 has a number of interesting design features, including separate but inter-linked boxes for each driver, a part sloped, part curved baffle, internal porting and an external passive crossover. This external crossover means that there are no physical changes required to use the SL2 in a Linn Exakt active system, making this a straightforward option.

So we're very pleased to add this rather special classic speaker to the SpeakerFilters portfolio.  Bringing the opportunity to apply Linn Exakt advantages to those who want to get the best out of their Naim speakers.  The filters were developed using a Linn Exakt front end and classic Naim NAP250 power amplifiers - a great balance of the best from both companies.  They're available to SL2 users "off the shelf" right now in three flavours which are provided to every customer:

- Standard based on the original SNAXO crossover
- With an additional 0.8dB attenuation for the tweeter
- With an additional 0.8dB attenuation for the tweeter and a 2dB bass lift below 100Hz

Feedback from SpeakerFilters customer CG of Birmingham:

"So how do they sound now? Well I wasn't ready for or, expecting the magnitude of the improvement. All the strengths of musicality & PRaT are there in spades but now hi-hats really shimmered, recording venue acoustics were tangible, bass lines are so solid, the space around instruments & performers improved, the decay on notes seemed to hang in the air. Boundary speakers are not renowned for their imaging but this has tightened up so that you can place individual performers, or even where the cymbals in the drum kit, are. The mid range has a much smoother integration. The slight mid/high frequency brightness had been tamed & the somewhat bass light presentation was gone leaving me wondering if I would still need my sub. (I have still got it in the system but I've dialled it down about 30%).
The end result is so impressive, I've done no work today, I've been sat here listening to track after track. A big thank you to SpeakerFilters - another awesome job."
