BLAM's Signature collection summarizes Guy Bonneville's more than 25 years of experience in designing and manufacturing car speakers. Signature is exactly what BLAM means by the term "French Sound".
The loudspeakers of the Signature collection are designed from start to finish in BLAM's laboratory and the products are assembled by hand in France. All elements of the speaker sets have been tested and paired individually.
Signature 165.300 in a nutshell:
Mid basses
The Signature 165.300 separate series 6.5″ cast-frame WS 6.300 midbass has a very stiff but light fiber cone, NBR upper suspension, Conex lower suspension and a 38mm voice coil. The midbass are really sensitive (93.2dB), so the Signature 165.300 does not require large amplifier powers for the required amplifier power.
- 6.5″ (165mm)
- Playback range: 50Hz – 5kHz
- Sensitivity: 93.2dB
- Midbass impedance: 2ohm
- Midbasso installation depth: 81mm
- Midbass installation hole: 142mm
Middle tones
The MS 3.55 is a three-inch midrange of cast bodies, which is recommended for installation in a 0.3-1.9l case. The phase-plugged elements are similar to the mid-bass with a rigid but light carbon fiber cone and NBR and Conax suspensions. Midranges are with a 20mm voice coil and a large 55 x 10mm magnet.
- 3.0″
- Playback range: 200Hz – 27kHz
- Sensitivity: 88dB
- Impedance: 3ohm
- Installation depth: 46mm
- Mounting hole: 72.5mm
Trebles
Signature 165.300 – series TS 20HR tweeter is physically one of the smallest on the market. In designing the tweeter, the most important criteria have been the soundness of the sound and the lightness of the sound, but in addition to this, we wanted to make the element as small as possible, keeping in mind the tight treble positions of new cars. The tweeters are also supplied with slim bullet-style surface mounting cups when the speakers are installed as surface mounting.
- 3/4″ (20mm) textile cone in treble
- Treble playback range: 2.5kHz – 43kHz
- Tweeter impedance: 5ohm
- Tweeter mounting hole: 33.6mm
- Treble outer diameter: 36.2mm
- Includes surface mounting cups
Passive crossover filters
The Signature 165.300 includes compact-sized 6/12/12dB passive crossover filters. Air core coils with very low resistance and metallized polyester capacitors are used in the filters.
Split frequency: Midbasso / middle tone: 300Hz
Split frequency: Treble: 10kHz
"The S 165.300 is a very noble speaker set that scores with its originality and character. The French-made chassis is reminiscent of the master hand and the sound just speaks for itself.”
