I have tried Jordan's, 4 JXr6 a side in a line array with peerless 200mm HDS for the bass. They were sent back because they didn't meet the manufacturers specification. The Peerless are now in the computer room on bass and my new speakers in the lounge are Tannoy Canterbury SE's. The only drivers I ever heard that came remotely close to full range with few issues was the Manger bending wave transducer and Ambiance ribbons. Both demand the fastest tightest bass driver crossed over above 100Hz. All so called full range drivers need help in the treble or bass and all suffer inter modulation distortion issues as well as those already mentioned in response to your post. I would not go for the Jordan's unless you hear them first or anything else for that matter until you are sure their sonic signature will satisfy. Building good TL or TQL cabinets takes a lot of effort & fine tuning to get them right. If you are infected incurably with the full range bug. I would try auditioning the following AER, Supravox, PHY, The alnico Fostex full rangers, Feastrex, Visaton B200 which I think offers the best value or the SEAS exotic who at least seem honest with their response curves. If you are open to using vintage drivers or building a line array the possibilities really open up. Madisound has a decent range of things to check out. Don't know if this advice helps or confuses but putting my 2 cents worth in anyway. Cheers thermo
