Ampeg Expands Portaflex Series With New Cabinets

Ampeg PF-115LF Bass CabinetAmpeg has unveiled a new pair of bass cabinets in their Portaflex series called the PF-115LF and the PF-410LF. While the series previously had a 1×15? cabinet, the 4×10? is a first for the series.

Both of the new cabinets are built with a 15mm poplar ply enclosure, covered in black diamond tolex with a vintage B-15 grill cloth. The new models also differ from the rest of the series by including shelf porting for additional low frequency extension.

Handling up to 400 watts, the PF-115LF gets a more vintage tone than its predecessor by leaving out the compression tweeter and including only the 15? Eminence driver.

Weighing in at 73.4 pounds, the PF-410HLF has a power rating of 800 watts at 8 ohms. In addition to four 10? Eminence drivers, it carries a 1? HF compression driver with an L-pad level control.

The Ampeg PF-115LF and PF-410HLF will become available in the second quarter of 2012 with MSRP’s of $489.99 and $769.99, respectively. For more, check out the Ampeg website.

  1. Response down to 55hz and 57hz! My low-B is 31hz – if I just want to hear the octave, I’ll play the octave! This doesn’t even go down to low-E on a 4-string (40HZ). Come on, guys!

    • Find someone who sells an enclosure with one of these in it http://www.usspeaker.com/B&C-21SW152-1.htm

    • @[1538974008:2048:Michael O’Toole] Thanks, but 10s are more responsive than a 21′ speaker for bass guitar – I use the Acme Low-B 210 cabinet: http://www.acmebass.com/ For subs, I use 15s from Cerwin Vega, as 18s are just too big and too heavy. I can imagine how big the cabinet needs to be for those 21s!!

    • Joseph M. Orost Most cabs won’t produce below 40Hz and most amps have a roll off below 50Hz to stop speaker damage, and there is the whole issue with human hearing too.
      Read the articles on the Barefaced website (amazing cab maker the owner Alex Caber is) and he explains it well.
      The frequency response stated is also probably that of the speaker not of the cabinet as a whole, either way the harmonic distortion (overtones) and pshycoacoustics will mean you’ll hear it, and the bottom end rumbled out means you’ll feel it.
      Guys like Yves Carbonne play down to 20Hz, I doubt any cabs can reproduce that, and few PA systems. Think about it this way, you can hear the low B of your bass through head phones.
      If that’s not what you meant by that then I feel a bit silly haha ;) !
