Big Bass Tone That's Easy to Move

Your bass rig will pack a punch with the Ampeg Portaflex PF-115LF bass cabinet . The Ampeg PF-115LF cab is modeled after the iconic B15, but it has upgraded components for even better performance and reliability. A ceramic 15" Eminence speaker provides the big bottom-end tone that Ampeg is known for. And you'll notice your tone is solid and defined, thanks in large part to the 15mm poplar ply construction which reduces resonance and distortion. So bring a classic look and sound to your next gig with the Ampeg Portaflex PF-115LF bass cab.

Ampeg Portaflex PF-115LF 1 x 15" Bass Cab at a Glance:
  • Ported design for powerful bass
  • Hardwood construction for better sound quality
  • Designed for convenient gigging
Ported design for powerful bass

Big bass tone relies on moving a lot of air, and the ported design of the Portaflex PF-115LF lets you move a lot of it. You get an extended frequency response (down to 32Hz) without sounding muddy or indistinct.

Hardwood construction for better sound quality

The PF-115LF is constructed with 15mm poplar plywood, which is exceptionally more rigid than MDF or composite materials. This means less resonance, so you'll hear solid, defined bass tone instead of the sound of a cabinet shaking. Naturally, the strong construction means the PF-115LF is ready for the rigors of the road.

Designed for convenient gigging

Not only is the PF-115LF built to last, but it's also designed to make your gig setup and tear-down easier. Integrated side handles make it easy to move - even more so when you use the included caster set.

Ampeg Portaflex PF-115LF 1 x 15" Bass Cab Features:
  • 400-watt 1 x 15" bass cabinet
  • Ceramic Eminence speaker for exceptional sound quality
  • Dual parallel 1/4" jacks make it easy to combine with additional cabinets
  • Rear-ported design extends bass response
  • 15mm poplar ply construction adds durability and increases sound quality
  • Removeable casters for convenient transport
  • 8 ohms
Get big bass tone at any gig with the Ampeg PF-115LF!

Love the lows from this cabinet

This gives some great lows and you can feel and hear the bass. I needed something that would give lows without running through the main system for worship. We lack subs currently and we had some speaker problems that were distorting the system when I was running from my Ampeg DI box. Nice warm tone, can go muddy if you boost the lows too much though. This cabinet is not suited for styles of music that require a lot of mid range. For that the non-ported designed with the driver might be better suited. The porting on this amp helps the "feel" in the room where bass is concerned. I prefer a more old school deep bass, so this cabinet works well for me with the PF-500 head. Very lightweight, I am glad I purchased this amp and cabinet from Sweetwater. Along with the Fender American Standard Jazz bass and Ampeg SCR-DI box(all Sweetwater purchases with Kevin Spunde), the tones are great for me.

Big Bottom

Got this to pair with the PF-115HE and PF 500 amp. I needed to retire my SVT because I was leaving a band with a trailer to a situation where I was going to have to transport my own rig. This rig is easy to transport and sounds fantastic. Together in a stack the 115-LF delivers a huge low-end and the 115-HE gives me the definition when stacked. Added bonus is that the HE w.fliptop is great for rehearsals and the LF alone will do small gigs no problem. That said, they sound best together . . . really nice, solid, Ampeg tone. I haven't moved it around or "abused" it enough yet to give an opinion as to how well these PF cabs will hold up but they seem to be solid and well built . . . oh, and they look fantastic.

First, I only do business with Matt Kreager because he's good at what he does and he never tries to sell me what I don't need. Okay, I connected my PF500 head and plugged up one of my 3 Custom built J Style basses and I couldn't believe what I was hearing coming from such a small enclosure. Punch, bottom, growl, mids, highs virtually every thing I have always wanted to get but hadn't up to that point. Now I am considering buying another one. Wow!

Great Ampeg Rumble

I ordered two of these cabs, and, received them in two days. Great job, Sweetwater. I have an SVT 3 Pro Amp head tha is 450 watts into 4 ohms. Hence the need for two cabs. (8 ohms each) I hooked them up, and plugged my American Fender Jazz 5 string bass and, Wow!!! I can blow the roof off, with the amp at less than half volume. I also hooked up a Carvin 450 watt head, and had the same result. I took them on a gig, a week later, and, the guys in the band loved the deep growl that I was getting. It was amazing. I would recommend these cabinets to anyone. Also, they are very easy to move around with the removable casters. They are far lighter than I would have imagined. I had no trouble lifting them in and out of my Dodge Caliber, mini van. So if you want a deep, full, sound from your bass. Get em!!!
