Sealer came in today so, hopefully over the next couple of days I'll get the woofers and midrange sealers and find out if I need to dig deeper with the sealing such as the midrange enclosure and the crossover. If needed, I will have to get something like rope caulk for the sealing and also to recounted the woofers.Thursday, July 24: Cleaned and applied the sealer to the woofers surrounds, dust caps and midrange drivers. Did not seem to need much. Did the push test and the woofers took about 2x the time to rebound and there was no midrange movement so, I think all may be good. I will know more tomorrow when I play them. Easily enough for another coating left in the original jar so the extra jar I bought may just be surplus; maybe an excuse to look for another set of Fives :).

Well, tried the rebound test after letting them sit most of the day and no improvement so suspect I will need to pull them. The person who changed the caps replied this afternoon, the gasketing looked good when he pulled the woofers took make the change so he reused it. Not a good idea so will need to get some caulking to seal the woofers to the cabinet. Might try to get to the crossovers and seal their edging also. Looks more and more like a project.
Tomorrow I will give them a listening test to see if any improvement

Got a couple of rolls of closed cell foam draft sealer. Size was wide enough to run 2 strips around the woofer frame. The old seal one one was missing about 1/8" and the other was so compressed in places and not others and in one spot hanging, not even on the baffle so these suckers were leaking worse than a sieve.
The mid enclosures were going through in very tiny holes, nothing like what has been described but, I still robbed a bit of putty over each hole. Buttoned it all up and now the woofer take a bit more than a second to rebound and settle so, good enough for government work.
Threw on some pipe organ and when it went low, those woofers had no issues being nice tight and delivering while with the Klipsch Heresy IIs did not know the notes even existed. Admittedly, almost nothing I ever listen to goes that low but, this is a test. With the Wharfedale W70s, they get down there but do not have the impact a set of pipes at that low a range impart. Pretty good for the Wharfedales, though. The Wharfies deliver a more delicate presentation and at lower volume levels do not close up as quickly. I think it is down to the environment the speakers were designed to operate in this might be an issue for me as I am trying to plan for the future.
After only listening for about 6 hours, it looks like the Klipsch HIIs, The Advent Loudspeakers and The Smaller Advent Loudspeakers are all out of the running leaving only the W70s and Five.
So far have had the Philips 797 receiver, the Sony STR6120 receiver ans Sherwood S9500c amp on them. The Sherwood is the smallest with only 20 watts per channel rms while the others have 60 per. The Sony after years of going back and forth against the Philips is the clear winner but only by a small margin. The Sherwood, though is giving the Sony a run for its money. I do not play my music loud enough to give the 3x more power of the Sony that advantage.
Tomorrow, I will throw on the Yamaha CA61II amp and Sherwood SEL200 receiver and maybe the H-K 630 and get a better feeling as to what gets a 2nd chance. Also will give me more time to compare them to the Wharfies.
