When your combo amp's original speaker gives up the ghost, you need a replacement that won't leave you scrambling before your next gig. The Jolt-8 is built for bass players who need reliable performance without the boutique price tag. This 8-inch woofer handles 175 watts RMS and delivers the punch you need for small to medium venues, rehearsal spaces, and studio work.
What sets this driver apart is its focus on the frequencies that actually matter for bass guitar. The 75 Hz to 5 kHz range covers your fundamentals while giving you enough midrange presence to cut through a band mix. That 40-ounce magnet and 2-inch voice coil provide the magnetic strength needed for tight response and quick recovery when you're digging into those low notes.
The paper cone with cloth surround strikes a good balance between warmth and definition — you get that classic bass tone without the muddiness that can plague cheaper replacements. At 91 dB sensitivity and 8-ohm impedance, it matches what most combo amps expect to see, so you won't run into impedance mismatches or power transfer issues.
This isn't a speaker for outdoor festivals or large venues where you need maximum volume. But if you're playing coffee shops, small clubs, or need a reliable practice amp speaker that won't fold under pressure, the Jolt-8 delivers consistent performance. It's also solid for custom cabinet builds if you're putting together a compact 1x8 or 2x8 setup.
Bottom line: This is a workhorse replacement speaker for bass players who need reliable performance at small to medium venues without paying premium prices for boutique components.

Frequently Asked Questions
Will this fit my bass combo amp?
This 8-ohm, 8-inch driver works with most bass combos from Fender, Ampeg, Hartke, and similar manufacturers. Check your amp's power output — this speaker handles up to 175 watts RMS, making it suitable for practice amps up to medium-powered combos. Always match the impedance (8 ohms) and make sure your amp doesn't exceed the power rating.
How loud will this get for live gigs?
The Jolt-8 works best for small venues, rehearsal spaces, and recording rather than large live performances. With 175 watts RMS and 91 dB sensitivity, you'll get adequate volume for coffee shops, small clubs, or practice with a drummer. For outdoor gigs or rooms over 100 people, you'll want larger drivers or multiple speakers.
What kind of wire do I need to connect this?
Standard 16-gauge speaker wire works well for most installations. The terminals accept bare wire, spade connectors, or banana plugs. Never use instrument cables or XLR cables for speaker connections — that's a recipe for problems. The speaker doesn't include wire, so grab appropriate gauge speaker wire for your cabinet setup.
Can I use this to replace a blown speaker in my combo?
Yes, if your combo originally had an 8-inch, 8-ohm speaker and your amp puts out 175 watts RMS or less. Remove the old speaker, note the polarity, and connect the Jolt-8 the same way. The pressed steel frame should mount with your existing screws in standard 8-inch cutouts. If you're unsure about power or impedance matching, check your amp manual first.
