I've started a few threads about our current products the last week, but this is where the fun is! This will be a development thread for our upcoming full range, active cardioid floorstander.
Current project name: "Saranna". The above is an early sketch of how it may look. Not obvious from the drawing but the back is more narrow than the baffle, so the side panels will likely be slightly curved in towards the back.
Sigberg Audio is currently known for loudspeaker systems consisting of monitors and subwoofers. There are two obvious segments of the market that we cannot reach with our current products:
1) Those who prefer floorstanders.
2) Those who do not want subwoofers.
The Saranna aims to address that.
Key Characteristics (subject to change)
- Huge soundstage, and rich, natural in-room sound (in line with other Sigberg Audio products)
- Full range (20-20,000hz) in-room response
- Cardioid midbass and midrange
- Ported enclosure (can be sealed by consumer for room tuning)
- As our other designs, placement close to the wall will be supported (but further out on the floor will work too).
- Simple presets (click a button on the back) for bass/placement adjustments, plus full 9 band EQ onboard for taming those room modes
- Dedicated preset for mating the speakers with our subwoofers; This presets introduces a high pass in the speakers, matching our subwoofers perfectly.
- 3 channel, 600W amplifier per speaker
- Bass: Two 8" aluminium cone subbass drivers (fs:25hz)
- Midrange / Tweeter: 8" coax consisting of a midbass/midrange paper cone and 1.7" polymide compression driver
- Dimensions: 26x107x34cm (~10x42x13 inches)
- Expected frequency response (anechoic): 28-20,000hz +/-3dB
- Expected in-room extension: 20hz (-6dB)
- Cardioid dispersion from ~150hz and up
Some preliminary measurements (in-room) of prototypes:
In-room response at listening position with the speakers 10-15cm (4-6 inches) from the wall (left+right+avg):
10-200hz in-room (listening position, no subwoofer, no smoothing). Note that reference level is 75dB (avg of 300-5,000hz).
Relative to the reference level, in-room -3dB point is 22hz, and -6dB is 16hz:
