, the Crown Reference Studio Reference I or II have a Damping Factor: of >20,000 from 10 Hz to 400 Hz.

the speaker grille and mounting points on the motorboard do not look to be home made

Mark Levinson is owned by Harman since 1990

these are not 1963 Heresy speakers , a 1963 would have different dimensions ,plus the midrange horn is for a 1967 and up speaker

the Topping PA5 amps have an extremely high failure rate , these are cheap amps from China built for the short term + they are not repairable , once the warranty expires , you're 329$ for the PA5 II PLUS -the Fosi are even lower quality . I would recommend you to avoid these 2 amps you can buy a high end Yamaha A-S 301 60wpc @8 Ohms for 350$ including an exceptional preamp or a Yamaha A-S 501 for 550 $ 85 wpc @8 Ohms , both these stereo amps will last a lifetime of worry free operation . https://usa.yamaha.com/products/audio_visual/hifi_components/a-s301/index.html https://usa.yamaha.com/products/audio_visual/hifi_components/a-s501/specs.html#product-tabs

dont get rid of your old klipsch networks since the parts are very sought after due to their quality

there are 2 pairs of Heresy 1 , low value is 500$ per pair , the taller speakers are Forte 1 or Forte II , 800$ no problemo , go over to the Garage sale section , place an ad , the speakers will sell in no time , there are lotsa forum members in Houston

reach out to klipsch Parts dept through email , attach the pictures and ask them to give you the klipsch part number for the RSB-6 subwoofer PCB , once you have the correct part no , and if the part is available , you would have to order it through klipsch Thailand https://support.klipsch.com/hc/en-us/requests/new

1951 Khorn crossover, Jensen woofer , University SAHF mids driver , T-35 tweeter

Here's a 1955 Khorn 3 way schematic for the Model K-500 / 5000

the Technics SU amps do not belong to a Class , they call it a full Digital amplifier , it does not have an internet port but it does have USB connectivity and it can be calibrated , basically a HIFI computerised Smart amplifier .

tx for the feedback

how can these subs become bass reflex speakers ? the subs are horn loaded with their own driver , the enclosure is sealed

gone

are you getting a reading with an Ohmmeter

it depends on the brand , Crown have very special Class-D chip amps that sound fantastic with fewer parts that can fail

definitely

excellent choice

it can be fixed

you can always buy a set of Heresy of any generation and use them in conjunction with the CW 3 , that would be the ideal setup for better vocals , there is no need to replace the CW 3 , but only to supplement it with better sound

you cant compare a Cornwall with a Heresy , these are 2 different speakers , the Heresy is hands down the best speaker for Vocals , period , because it's a Studio Monitor style speaker for crisp and detailed HF .

Definitely , the 3 way Heresy is a phenomenal speaker.....any generation

great choice
