Cinemator - On-Wal-In-Wall LCR Speaker DIY Scan-Speak Speaker Kit by StereoArt

Cinamator by StereoArt

Scan-Speak DIY LCR speaker kit for on-wall or in-wall installations by StereoArt 

Priced per single speaker - 1 tweeter, 2 woofers, crososver components, wiring, screws, damping and terminal plates.

The kit is based on 5" Revelator woofers in sealed cabinet.

We offer 2 versions of kit - with Revelator tweeters D2904/710003  and higher end version with TPCD/Textreme Illuminator  D3004/666000

The kit is supplied as set of parts and you need so build it yourself. 

We can supply cabinets in any color or veneer you'd like and we can supply fully assembled speakers,  just ask!

Main facts for Scan-Speak LCR kit Cinemator by StereoArt:

- The goal of design was to develop universal high-sensitivity high-end LCR speaker as for in-wall too on-wall installations in relatively compact cabinet (on 11cm deep!)

- cabinet construction is very simple while have good shape to avoid internal resonances and baffle diffraction problem.

- woofers: 5" Revelators with high max excursion to get best possible low end from compact LCR, what will allow good integration with subwoofer and light come with very good and detailed midrange.

- tweeters: we offer 2 variants, one  with silk dome D2904/7100003 (black) or D2904/7100002 (silver) or higher end version with Textreme/TPCD Illiminator D3004/666000. 

- crossovers are built to get best frequency and phase response under wide angles. Very good soundstage in stereo and extremely good integration for multichannel setups.

- Our goal was to get best phase transition from woofer to tweeter and have almost linear phase.

- Crossover schematics: 2nd order for woofers, 2nd order for tweeters. Minimalistic design - only 2 coils and 2 capacitors (TPCD Illuminator)  and additional 2 resistors  (Revelator version)

- Premium components for crossovers: Mundorf MCap EVO Oil capacitors, Mundorf MResist Classic resistors, Mundorf Baked Aircore coils, Oyaide 102SSC internal wiring

- Oyaide 102SSC hook-up internal wiring

Cabinet: 18mm MDF

We will provide detailed drawing with kit.  

Cabinets are very simple and can be built at home if proper tool for holes routing available.

Mounting options: 

In-wall mounting is made with surround frame machined from 2mm steel. We will add more images soon. Full drawing for cabinet and frame available.

You can mount on-wall with a frame. For interior matching frame can be made with different colors or veneers.

Crossover: 

Both crossovers have similar topology - 2nd order. D2904 have additional resistors R1 and R2. 

Crossovers have excellent phase allignment, here is an example of reversed tweeter  for D2904 version:

• Frequency range: 65-22000 Hz +/-3dB (65-40000Hz for TPCD Illuminator version)
• Sensitivity ( 2.83V/1m ): 93-94 dB
• Nominal impedance: 4 Ω
• Max SPL: 114 dB
• Recommended amplifier: 40-150 W
• Cross-over frequency: 2600 Hz Revelator / 2500Hz Illuminator
• Enclosure type: Sealed cabinet
• Driver units: TPCD dome D3004/666000 Illuminator or 26mm silk dome Revelator D2904/710000x & 2x5" Scan-Speak Revelator 15W/8530K00
• Cabinet material: 18 mm MDF
• Speaker dimension (HxWxD): 760 x 290 x 110 mm ( 29.9 x 11.4 x 4.3 inch )
• Net weight: full assy 1265 kg ( 27.5 lb )

Application notes:

Speakers were designed as vertical front LCR channels for in-wall application behind acoustically transparent projection screen and as in-wall surrounds. While we worked on crossover design we also got excellent vertical of-axis and speaker can can be used as horizontal central speaker.

Most MTM D'Appolito designs have a problem with woofer cancellation at certain frequencies under certain angle, but we've got crossover what allow to cover at 3m watching distance from screen upto 4 front seats with +-2db with gentle suck-out at 2.5-3,5kHz, what perceives by brain as a flat due to equal loudness curve. 

For installation behind acoustical projection screens we recommend to build baffle and build speakers in.

On-wall version comments:  once speaker come out of wall it loose wall support on a lower end and gets baffle edge diffraction problems. 

If you use retracting screen or TV and want to use on-wall mounting, we recommend to mount speakers wide. This will balance the response, take a look on  graph for on-axis in-wall and 30degress off-axis on-wall 

Scan-Speak LCR kit Cinemator by StereoArt -  TPCD D3004 Green - in-wall, red on-wall, blue - on-wall 30grad.

As you see on measurements in-wall speaker have better balance, mounted on-wall on tweeter axis will have edge diffraction on midrange and with 30degreed off-axis it becomes as good as in-wall installation.

For on-nwall installations play with your processor's DSP and "house curve": +1-2dB on a bottom may give you desired balance.

For installation behind screen adjust upper part of response to compensate screen damping.
