Naim SBL Filters Added To The SpeakerFilters Catalogue!

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

A legendary loudspeaker from Salisbury company Naim, the SBL Mk1 has a number of interesting design features, including separate boxes for each driver, a sloped baffle, internal porting and an external passive crossover. This external crossover means that there are no physical changes required to use the SBL 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 SBL 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 1dB attenuation for the tweeter
- With an additional 1dB attenuation for the tweeter and a 1dB bass lift below 60Hz

Feedback from SpeakerFilters customer CG of Birmingham:
"From SNAXO to Exakt: I was running a Naim SNAXO / SuperCap with my active SBLs - an improvement over passive - which gave great PRaT but they still sounded a bit forward. At a dealer demo evening I was listening to a Linn/Kudos Exakt active system thinking this system sounds amazing and the transparency that the Exakt technology brought, which performs the crossover in the digital domain,  was breath-taking. If only Exakt was available for the Naim SBLs.

At that same demo I learned about SpeakerFilters who design Exakt filters for speakers not covered by Linn. I worked with SpeakerFilters on a design for the SBLs and when these were loaded into my system it was clear that this was an improvement with better definition & spatial separation. The soundstage was more clearly defined & I was in heaven. The slightly bright presentation was gone, bass weight was enhanced and all the strengths of musicality & PRaT that SBLs are renowned for were retained. Hi hats shimmered, room acoustics were tangible, the space around instruments & performers improved. 

The end result? Absolutely stunning. If you thought going from passive to active with a SNAXO was a big step... from SNAXO to Exakt is like having seven league boots on! Really, it's that good"

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 SBL.

Great Reception for SpeakerFilters at HifiWigwam Show, March 2019

SpeakerFilters custom Exakt filters were featured in Wam forum member Sunbeamgls' room at the show.  Featuring a Linn Akurate Exakt source through Lejonklou power amplification, the following independent comments were posted on various forums about the system that included our Exakt filters for the Gauder Akustik Isophon Corvara loudspeakers:


Jarvis: "my most memorable rooms were Steve57, Coogie, Ian917, SunbeamGLS, MaxTheSonyGuy and Spider et.al"

The Flash: "sounding nicely balanced in that system."

Nopiano: "I agree with all the praise. They were evidently extremely well set up, and the system had a coherence and balance that was way beyond what I’d expected. Easy to enjoy!"

Richard A: "I’d like to add my plus one to those comments and this was my first chance to listen to Gauder. I loved the sound in your room, possibly the most natural/unforced of them all."

Lejonklou forum member u252az: "Sunbeams system was the first Exakt system I have enjoyed - worth going just for that"

CyrusUnofficial forum member hifinutt: "Gauder sounded superb . Very natural" and on the AOS forum "my favourite was the gauder akustik"

CyrusUnofficial forum member Czechchris: "I too liked the speakers you had playing"

Endorsement from brianandtrevors - specialist hifi retailer in Manchester


"Impressive results with the new Linn SPACE Optimisation and Graham Audio BBC monitor loudspeakers" say highly respected Manchester hifi dealer brianandtrevors.

We've been priviledged to work with specialist hifi retailer brianandtrevors / House of Linn in Manchester recently.  SpeakerFilters took SPACE optimisation measurements for Graham Audio LS5/8, LS5/9 and ATC SCM50SL speakers at brianandtrevors.  We then collaborated with Linn to have these models added to the list of available speaker models within Linn's DS and DSM product range.

Its great to hear back from brianandtrevors / House of Linn on how this has allowed them to further enjoy these speakers in a Linn system, reducing the effects of the room on the music.

We can provide this service for your speakers too.

Measurement of Your Speakers for SPACE Optimisation

NEW at SpeakerFilters.

Linn's SPACE Optimisation functionality optimises the sound of the system by compensating for bass mode boom in your room.  This allows the music to be easier to follow and frees up the vocals and treble information from being swamped by bass.

For a speaker to be used with Linn's SPACE Optimisation (SO) functionality, it needs to be measured.

Linn already produces a long list of speakers pre-measured for use with SO. Of course, Linn has not yet had an opportunity to measure every speaker made, and perhaps yours is one of those missing speakers. Now we are able to offer a service to measure your speakers to be added to the list of speakers to be used with SPACE Optimisation, giving you the benefits it brings to the music.  Send one of your speakers to us or we visit you - its a process that does not require any modifications or dismantling of the speakers.  We don't even need to connect them to a system.

Speakers previously measured by SpeakerFilters and already available in Linn's list of SPACE ready speakers include PMC Twenty.21, PMC Twenty.C, Q Acoustics Concept 20, Gauder Akustik Isophon Corvara, Heybrook HB3 Mk 1, Totem Model 1 Signature, Graham Audio 5/8 & 5/9, ATC SCM50SL, ATC SCM100SL, Mission 750 Limited Edition, Mission 780 Standmount, Mission 773e, Mission 790, Naim SBL and PMC TB2+.  We're therefore already experienced in measuring a wide range of speakers. Yours could be next.

Customer Reference:  SpeakerFilters measured Linn & Lejonklou forum member Donuk's Totem speakers to be added to Linn's SPACE optimization compatible speaker list.  Donuk said "More open, better soundstage, a satisfied customer"
