Description
SoundQubed BGS-CX64SL — 6.5" 2-Way Slim Coaxial Loudspeaker | 1" Titanium Compression Driver | 150W RMS | Sold Single
The SoundQubed BGS-CX64SL is a high-performance 6.5" 2-way slim coaxial loudspeaker engineered for car, UTV, and motorcycle/bagger audio applications where mounting depth is limited but output and clarity cannot be compromised. Featuring a curvilinear paper cone woofer, cloth surround, a 19.5 oz ferrite magnet, a 1.5" / 38.6mm CCAW voice coil on a KSV former, and an integrated 1" titanium diaphragm compression driver with a neodymium magnet, the BGS-CX64SL delivers 150W RMS / 300W max at 97 dB sensitivity with a frequency response of 120 Hz–20 kHz. Grill included. Sold as a single speaker.
The BGS-CX64SL’s slim design — just 3" / 77mm mounting depth and 3.25" / 83mm overall depth without grill — makes it ideal for tight mounting locations in bagger fairings, UTV roll bars, and motorcycle audio pods where a standard 6.5" coaxial won’t fit. The integrated 1" titanium diaphragm compression driver (neodymium magnet, Kapton former, CCAW winding) delivers crisp, detailed highs from 120 Hz to 20 kHz — no separate tweeter or crossover required. The curvilinear cone shape and spade terminals make installation straightforward in any application.
Why Choose the SoundQubed BGS-CX64SL?
- 150W RMS / 300W MAX @ 4Ω — High-output power handling for a slim 6.5" coaxial — built for real amplifier power in demanding installs.
- 97 dB Sensitivity (1W/1m) — Exceptionally high efficiency — delivers strong output with modest amplification, ideal for bagger and UTV builds.
- Slim 3" Mounting Depth — Fits tight mounting locations in bagger fairings, UTV pods, and motorcycle audio applications where standard coaxials won’t clear.
- 1" Titanium Compression Driver — Neodymium-powered titanium diaphragm for crisp, detailed highs — a step above standard Mylar dome tweeters in output and clarity.
- Curvilinear Paper Cone + Cloth Surround — Natural, detailed midrange character with controlled breakup and long-term durability.
- 19.5 oz Ferrite Motor — Solid motor for a slim 6.5" coaxial — clean, controlled output at real power levels.
- Grill Included — Complete install-ready package for a clean, finished look.
- Sold Single — Buy exactly what you need — order quantity two for a stereo pair.
Installation & Pairing Recommendations
Amplifier Pairing: The BGS-CX64SL handles 150W RMS at 4Ω. Set your amplifier’s HPF at 140 Hz to protect the driver and maximize output. Any SoundQubed 4-channel amplifier with 75–150W RMS per channel at 4Ω is a solid match — the S4-100 (100W x4) or Q4-150ABv2 (150W x4) are ideal for bagger and UTV builds.
Bagger / Motorcycle Install: The BGS-CX64SL’s 3" mounting depth and 5.57" / 142mm baffle cutout make it a natural fit for Harley-Davidson bagger fairing and saddlebag locations, UTV roll bar pods, and any tight-clearance motorcycle audio application. Grill included for a clean, finished look.
UTV Install: The slim profile and high sensitivity (97 dB) make the BGS-CX64SL an excellent choice for UTV roll bar and pod installs where wind noise and ambient sound require high-efficiency speakers to cut through.
Mounting: The BGS-CX64SL requires a 5.57" / 142mm baffle cutout and 3" / 77mm mounting depth. Overall diameter is 6.47" / 165mm (7" / 178mm with grill), overall depth is 3.25" / 83mm (4" / 103mm with grill). Motor diameter is 4.3" / 110mm.

Frequently Asked Questions
Q: What makes the BGS-CX64SL different from a standard 6.5" coaxial?
A: Two things: the slim 3" mounting depth and the 1" titanium compression driver. The slim profile fits bagger fairings, UTV pods, and motorcycle audio locations where standard coaxials won’t clear. The titanium compression driver delivers higher output and clarity than a standard Mylar dome tweeter — 97 dB sensitivity in a coaxial package.
Q: Is the BGS-CX64SL suitable for a Harley-Davidson bagger install?
A: Yes — the 3" mounting depth and 5.57" baffle cutout make it a strong candidate for bagger fairing and saddlebag locations. Verify your specific mounting location provides at least 3" of clearance before purchasing.
Q: What amplifier should I pair with the BGS-CX64SL?
A: The BGS-CX64SL handles 150W RMS at 4Ω. Set your HPF at 140 Hz. The SoundQubed S4-100 (100W x4) or Q4-150ABv2 (150W x4) are ideal matches for a bagger or UTV build.
Q: Is this sold as a pair or single?
A: The BGS-CX64SL is sold as a single speaker. Order quantity two for a stereo pair.
