Woofers and Tweeters

Thanks. The only way, that I know of, to remove light scratches is to do some light sanding. The water stains on these cabinets did not go deep, so the light sanding removed them too. I have used Bar Keepers Friend mixed to a paste to acid bleach water stains from veneer before. Google that for more info. LaScala bass bin with Dave Harris Epitrac 400 mid and Dave Ault's L-MAHL tweeter and using MC30s for power.

Lacking bass and fatiguing highs made me think of room treatment and preamp.

Some might find them ugly, but I like the figured woods.

I made so 1.5" tall risers to protect the bottoms. (they are hurt from abuse)

These were 3 states away from me and a mess, as you can see. Being that they were in StLouis and I was in central KY, I called @MookieStl to see if he could grab them for me (Thanks again Mook). He said that they were what the pictures show, but I wanted them anyway (I was hoping for the best). I'll spare you the details of what it took to get them back to being bearable. They are not perfect and still have a couple of small chipped places. I swapped out a few parts, such as the K55 on the K700 and installed the K53H on the K701 horns. I still need to get the grills mounted too.

Yes, with K&N filters... jk The caps would be the old paper in oil cans. I was not able to find them and forgot to take them off of the list. They most likely looked like the ones that were in Gil's Belle.

@Jeff Matthews It might be the preamp.

Sorry for any confusion. They are still for sale. MR74 AM/FM TUNER $400 needs alignment, oscillates McIntosh MI-3 oscilloscope for MR74 tuner (and others?) $400 K500 $200 each K77 round or square $125 ea AK4 $200 each Pioneer 15" woofer $75 Pyle 15" woofers $75 EVM 15L (only EV for bass horn) $140

You have a PM

I have a CD of the Planets. Playing Saturn, at ~ 7:50 and close to the 9-minute marks, there are notes lower than some of the speakers I have will reproduce. The RB75 and FB35 are 2 of the ones that say, 'nope, can't go there'. The woofers move in and out, but there are no sounds and nothing in the room vibrates like a sub would produce. Does anyone else have similar results with Saturn (not the youtube version)?

@Schwenke76 hasn't been here since 2022. He might get a notification in his email.

Yes, I guessed the same. Probably another one and done.

Sadly and thankfully at ~ 300:1 ratio.

What are these going in?

I try to be schooled every day. We are all born ignorant, some are determined to stay ignorant.

Only the ones that have not been taught to speak. A lady is walking down the street to work and sees a parrot in a pet store. She stops to admire the bird. The parrot says to her, "Hey lady, you are really ugly." Well, the lady is furious! She storms past the store to her work. On the way home she saw the same parrot in the window and the parrot upon seeing her says, "Hey lady, you are really ugly." She was incredibly ticked now. The next day on the way to work she saw the same parrot and once again it said, "Hey lady, you are really ugly." The lady was so furious that she stormed into the store and threatened to sue the store and have the bird killed. The store manager apologized profusely and promised the bird wouldn't say it again. The next day, when the lady walked past the store after work the parrot said to her, "Hey lady." She paused, scowled with an icy and deadly stare, and said with a hoarse voice, "Yes?" The bird, strutting back and forth on its perch in a cocky manner, said, "You know."

@WMcD said "Squawker is PWK's subroquet for the midrange. Dogs woof. Birds tweet. I don't really know what kinda critters squawk. A study in onamotapoetics too. Gil" What was I doing in 2001?

Bob suggested that there might be other problems that need to be addressed on some horns. A lot of people added damping materials to the metal K400 and a few others. The new Heresy addressed and corrected many complaints about the earlier offerings. Posting some of what Bob said just for the lol. “I will keep repeating this so all concerned will perhaps see it. I bought a pair of Heresys that had been someone had rope-caulked many years earlier. It was a pretty extreme case where the guy for some reason put that nasty stuff all over the tweeter, midrange horn and driver, the crossover and the woofer. The junk had been in there long enough that the rope-caulk had started to de-compose and the oil had dripped out of it and was all over the cabinet and even some of it on the woofer cone. When I tried to remove it, the sorry stuff had hardened and took all the paint off the horn and all other parts it had been applied to. Anyway, now if I have a ringing problem with a horn, I tighten up the screws holding the horn to the motor board real good. Bob C” “I am not criticizing the goal, just the technique. If tightening up the horn did not work, you could try a gasket around the mouth flange. If more is still needed, how about a large package of rubber bands to put around the horn? Anything except that nasty rope caulk. Bob C”

Nope. I would not do anything, I mean nothing at all to the Heresy IV, seriously. Roy and the team got that one right as right needs to be. Placement and what powers them are the only two things I would work on to dial them in.

It depends on the horn. The K700 is a lot less apt to need damping vs the K400. Which horn are you thinking about needing damping material? There have been many threads about this. Since there are so few remaining members who can help with this, I would google it to get a lot more info.

I bought the dot (Lil Wrecker). It was great meeting you Rich. I am really sorry that your ability to hear lower Hz has gone. To anyone thinking of buying any of Rich's other offerings, buy with confidence. I missed out on some other great deals.
