  Overall Opinion

  Use a minimum of two coupled, poses on the floor.
  
  The ideal, 8 units per channel.
  
  Directions for use: high-pass filtering 50 Hz, 2 units, or 40 Hz, 8 units, 18dB/octave
  
  Lowpass filtering 250Hz Max, 18 24dB/octave. Au-del there will be a coloring inhrente this type of load.
  
  Use of Hps quality (origin: JBL K151 now deprecated; JBL 2242 usable). Privilgier to loudspeakers strong BL, max 150g moving mass, the magnetic linear circuits. Including the JBL or RCF.
  
  Not at all made for the sub, absolutely avoid the bowls and heavy membranes rsonance low.
  
  
  
  In active filter sr well, with quality amp.
  
  
  
  Why is this box?
  
  
  
  Well when the sound shall be immediately used by seducing his punch and his place in the serious ridicule on the bass RFLEX or other direct radiation ... its flag on the right. At high power it is a slap phnomnale.
  
  A bit like the B115 Martin (descending lower course) or former Turbosound, excellent vintage.
  
  Costing a very lively, which is rediscovering the music!
  
  Setbacks beyond mdaille: they are bulky and not descend very low frequencies.
  
  
  
  A well used to obtain the quintessence.

  Overall Opinion

  Trs good subwoofer depending on its use: critical rev j'tais his gard dsastreuses after several costs in terms of impact and prcison.
  
  
  
  However, used between 40Hz and 100Hz MAXIMUM, with HP in the near CHARACTERISTICS of JBL K151 which is the HP used the design of 4818 by Don Keele in 1977 and not the E145 out APRS that date (or 2240H offers the alternative era by DK). Well, better than the JBL 2242 Fane Colossus 18B present one, would be an RCF LF18N402 IDAL, second choice is possible with the 2242H Beyma 18G50, the L18S800 RCF, B & C 18TZB100 Fane Colossus and 18B-600.
  
  
  
  To make a real serious stacks are four units ncessaires if we have a serious cut to 55Hz. Typing is good, inversely proportional to the prcison, which is normal for a bass bin. The high cut-off should really be 100Hz or less if the flag is reason parasites that make it really bad. Used in some discothques up to 160Hz with JBL E120 in Cabaret is so far the potential of this box to be remembered in 1977. It exists in diffrent brands as Don Keele ingnieur JBL's era had not been DPOS under the brand name of his employer because it was a request of a client factor enclosure that used HP JBL: these were Stage Accompany. It is also found in other client Atelier 33 HP JBL.

  Overall Opinion

  I'm not so ok with you eric you saw your signature aprcie jbl lot and I understand you "preached in your parish." It is true that the orrigine c'tait a woofer jbl jbl in boxes which recess is logical but if you compare the specifications of JBL K151, E155, 2240 or even 2242 (which could be mounted of origin in 4818) with that of the FCR L18S800 home CHARACTERISTICS are similar to telephone marketing as well say, the biggest diffrence is with the power which is almost double that of jbl woofer that is why j I chose this MODEL stronger than jbl (cash and seen the power that I shoot with amps dja very big.

  Overall Opinion

  These are incredible speakers that come out a monstrous power stroke using a crossover cut to 200 or 250 Hz mine are equipped with RCF L18S800 and edited with a brief RMx4050HD QSC amps monsters 800W parts to which it does not last long these HOLDS boxes have a very long range because the inverted flag sysem provides this feature. I highly recommend it although the weight and size are not his main asset (+-85kg, height 1.20m X 60 X 65) are for me the most subwoofers performance (in return) with its most powerful if they are fitted with good presenters!
  
  Attention the price is not for nothing because the original boxes are very rare!
