Hello!
My name is Flo. I am new to the Forum - and new to the whole topic of Speakers/Cabinets... (total NEWBIE)
I am putting this thread here because i read most of the Karlson-related posts here in the fullrange forum... hope im right.
I play electric bass guitar and want to build a speaker cabinet in the style of the Karlson/Karlsonator.
I do have skills in carpentry but not so much in elektrotechnical or acoustic/physics stuff :/
I hope you guys can help me out realizing my idea!
I already have a 10" speaker for my project - OBERTON 10B200
These are the specs/TSP:
https://oberton.com/en/?option=com_content&view=article&id=180:10b200&catid=49:ferrite-loudspeakers
Nominal Diameter: 10"/262 inch/mm
Impedance: 8 Ohm
Minimum Impedance: 5.25 Ohm
Power Capacity AES ¹: 200 W
Power Capacity ²: 150 W
Program Power ³: 400 W
Sensitivity: (200-2000 Hz) 93 dB/W/m
Frequency Range: 45 - 3000 Hz
Voice Coil Diameter: 51 mm
Voice Coil Material: Copper
Voice Coil Former: Kapton™
Voice Coil Winding Depth: 17 mm
Magnet Gap Depth: 7 mm
Cone Material: Glass Fiber
Basket: Die cast aluminiumMagnet: Feritte
Flux Density : 1.35 T
Resonance Frequency: 47.88 Hz
Mechanical Efficiency Factor (Qms): 9.27
Electrical Efficiency Factor (Qes): 0.341
Total Q (Qts): 0.329
Equivalent Air Volume (Vas ): 36.21 Litres
Diaphragm mass ind. airload (Mms): 43.75 grams
Voice Coil Resistance Re: 5.10 Ohms
Effective Diagram Area (Sd): 317.3 cm2
Peak Linear Displacement of Diaphragm (Xmax)*: ± 5.75 mm
Mechanical Compliance of Suspension (Cms): 0.252 mm/N
BL Product (BL): 14.02 T.m
V.C. Inductance at 1 kHz (Le): 0.84 mH
*First question would be if it is possible to put that speaker into a Karlson-Style cabinet and can it be tuned around 60Hz? (at least, this is what i was told to be "best" for bass guitar (when vented??)).
*Secondly i want to stack another, existing box of mine onto the enclosure (or/and other way around) - meaning that depth should ideally be 325mm(12.8Inch) and width 328mm(12.9Inch). Is it possible to just adapt the height to get to an useful result?
*Third - i want to "integrate" my existing amp into a recessed area on the back of the housing/cabinet. Here is a picture of my Ibanez"Promethean"-Bass combo...
i want to do it in the same way.
I really love the "looks/design" of the Karlsonator with its curvy acoustic lense/aperture and i was already looking at some fascinating stuff you guys are building here.
Also i found this guy @freddi on youtube who plays an electric bass through his selfbuilt xki-Karlson:
Could someone please help me out to calculate/design the desired cabinet/box or point me in the right direction?
