    Hi Ivica,

    Albeit looking similar I do think there is a real sonic difference between the older PT wave guides (PT-F95HF) and the VTX F12 #5006815. I have had both and the newer certainly sounds...

    Yes, that is the one.

    Emotionally they are generally ruled out day one, due to looks and material, compared to other much more impressing packages.

    But in reality, they perform very well with...

    I would definitely look at a modern wave guide before going the diffraction slot horn-way. To me the M2, 4367 and even the el-cheapo VTX-F12 WG does sound better than many expensive horns with a...

    Take off the snout on the 2450 creating a sort-of 2451 with 1.5Ē exit. Use an adapter plate for the wider bolt circle under the snout an mount to a moder wave guide. The 1.5Ē exit works much better...

    I agree Ian,

    The truth is that the HW is not important, the algoritms are. From having had the fortune to having sample many DSP’s I would say that BSS is superior to most from a sonic...

    Sorry to be a party pooper but how do you measure and with what gear. Unless you can make certain your gear is calibrated and you are measuring both drivers with exactely the same...

    Hi Ian,

    Sure is. However you can mount silent Noctua fans or a slow 120mm fan and be done. Even in a quiet living room.

    Some use them without cover and the fans disconnected. Seems to work...

    Hi,

    Not knowing how your signal chain looks like it is in general a bad idea to introduce "resistors" in the signal chain unless the source is very low impedance and the "reciver" is high...

    Hi Juergen,

    It is not advised to change to Beryllium diaphragms in those speakers having a 2Ē 475Nd driver and especially not in a 2-way construction.

    The Beryllium diaphragms will fall off...

    Magic of rubber :-)

    This is an interesting observation. I think we all were of the opinion that "HPL" was really a "H" without the rubber magnet protection. In reality the JBL rubber protector does have magical magnetic...

    Not sure those are original dias.... Looks like someone swapped in something else.

    I have never seen a JBL dia looking like that with leads trough the dome.

    That looks really odd.

    Normally the phase plug never rust from what I have seen. It is the steel outer ring that corrodes and that is not uncommon due to leaking back cover or water coming in from...

    Greetings,

    The STX #5006815 is a completely different animal than the 2332. Not comparable at all. 25 years apart. I like 2332 and have had a bunch of them but nowhere near the STX. Same WG as...

    Here are some pictures. 2453 is a straight fit on the VTX F12 waveguide.

    Any other JBL driver can be mounted with an adapter. I have posted about this in an earlier thread, including a drawing.

    Hi,

    You should be fine with a 4" (2447, 2450SL, 2451, 2452 or 2453) 1,5" driver with SL diaphragms. No real need for UHF with those diaphragms just some tweaking in the DSP. The 243* drivers do...
