    Default Definitive Technology BP20 Mod Thread

    Going to be using ESA on the tweeter, SA on the woofer + mills resistors!

    I have modded these once before with Auricap and Solen - the Clarity parts are easily triple, quadruple in size...

    Should be fun! :)

    Will attach pics of the previous mod! (Was like my third crossover modification I had ever done!)

    Those aluminum tweeters can be a bit harsh on some material without mods.

    I modded the Xovers on my BP-30's with help from Danny Richie/GR Research. I left the originals in place and moved the new ones outboard into wooden boxes. Also rewired the spearkers w/ 16 awg solid core OFC wire. Took awhile to burn in but ultimately vastly improved imaging, and gave a much smoother, more liquid presentation. I like it!

    The BP30 is on my short list for a second rig...

    I would love to own the BP30 or the BP3000TL for a secondary 2 channel rock n roll slammer rig...

    The owner wants to keep them internal so I am going to do a point to point crossover and breadboard mount the caps inside the cabinet with probably velcro unless he wants to glue them in there...

    Leaving the internal wiring the same...

    If you ever see a pair of BP30 in great shape at a steal lmk! :)

    Wanted to note the BP20 is the original Def Tech line up where it used the Vifa soft dome and vifa (now scan speak midbass). This was before Definitive was well established into the market like they are now.

    Still a great speaker but just not all their own designs.

    I had a pair in here a while back that my buddy purchased and Erniejade bought from him - by far one of the loudest, gut wrenching speaker I have heard that was not horns...

    Point to point with remote mounted caps... was a bit tricky but this turned out good with no extraneous wire :)

    Apparently later on Def Tech switched to a dual board design (a very cheap one at that) - so I basically gutted it completely and started fresh... was interesting to say the least
