Linn Keilidh with Hiquphon OW2 Tweeter - Exakt Filters

For some time, Hiquphon's rather fine OW2-92 tweeter has been favoured as an upgrade or replacement unit for those speakers for which the original tweeters are no longer available. Speaker such as Katan, Ninka and Keilidh have often been equipped with OW2-92.

Whilst these drivers are a good match in a passive system with its large phase errors and crossover approximations, in an Exakt system, a more precise match is required.

Therefore SpeakerFilters is very pleased to announce the latest in a range of Exakt filters designed specifically for the OW2-92 tweeter in classic speakers - the evergreen Keilidh floorstander.

Feedback from customer AO:

"your filters tame any harshness compared to using the standard filter"

These filters are available now for £195 a pair.  Bi-amp and Tri-amp filters are provided.

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

From Cambridge company Mission, the 78cse Aerogel centre speaker contributes to an Exakt surround sound system, in a 3-way configuration (mid-bass, outer tweeters, centre tweeter).

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 78x series speakers in a surround sound system.  The filters are available to 78cse Aerogel users "off the shelf" right now.  We can also make the physical changes to the speaker, if required.

Please note that early versions of this speaker (the 78c) 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.

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 772e speakers.  The filters are available to 772e users "off the shelf" right now.  We can also make the physical changes to the speaker, if required.

Mission 783 Aerogel Floorstanders 1999 to 2004 Exakt Filters

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.

Naim SL2 Exakt Filters

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."

Feedback from sound technician S from Birmingham:

"I’m highly impressed, it’s not that often that a system makes a significant positive impression on me, but that was lovely. As a sound technician, I’m often drawn to, and fixated on flaws, but there were none of note!"

 

Mission 790 Exakt Filters

The Mission 790 is a 2-way standmount design that's slim, elegant and features a complex curved cabinet.  Being a 79x product, its from the upper end of Mission's extremely comprehensive product range.

Now they perform even better with Linn's Exakt systems using filters from SpeakerFilters.

So we're very pleased to add this high performing speaker to the SpeakerFilters portfolio.

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 Mission 790.

Mission 77c1 (Portrait) Exakt Filter

The Mission 77c1 is a 3-way centre speaker that's intended to be part of a home cinema system.  However, it also makes a good medium sized standmount speaker when used in portrait mode as a stereo pair.

Now it performs even better with Linn's Exakt systems using filters from SpeakerFilters.

So we're very pleased to add this interesting approach to the SpeakerFilters portfolio.

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 Mission 77c1. 



We will add a landscape version of this filter to the catalogue in due course, to permit its use in a Linn Exakt surround sound system.



(Please note this is the 77c1 speaker which has 2x mid-bass drivers.  These filters are not compatible with the earlier 77c which has one mid-bass driver and one mid-bass passive radiator.  Please check your speaker carefull as they are not clearly labelled on the back panel.  To check, remove the front grille to check that the drivers look like the image below. Thanks.)
