Klipsch Mod


I've upgraded the crossovers and internal wiring, lined the cabinets with anti-vibration sheets, upgraded the speaker connectors and I'm about to solder the speaker connections. (Waiting for Crites titanium tweeter diaphragms to be back in stock). Im considering putting in a high frequency attenuator like you see in older speakers like altec lansing santanas, Sony HPM 100s, etc. What do you think?

Damp the horns (mids and highs) and the woofer baskets with Dynamat, or a similar material. A great sq upgrade. Forget the attenuators.

Yup. Did that. Yeah I'm reticent about putting some cheap $15 attenuator into the signal path...

You want L Pads, not Pots. L Pads do not alter the impedance, Pots do. My L-Pads from Parts Express are 16 ohm for my 16 ohm speakers.

Speakers are like blind people who have been kidnapped. They do not know where they are being taken/kept. Possibly moved to a different hangout at any time.

I am a big fan of adjusting mids to the woofer and adjusting tweeters to the mids: in the space they will be used, for the ears that will be hearing them.

I use a SPL meter on a tripod at listening position and take my time with this CD’s test tones. Last time took 1-1/2 days, they never sounded better!

Pots are better than no control, I restored two pairs of AR-2ax's, replaced original pots with new pots on 1 pair for my office and refurbed original Pots for the pair in my Garage/Shop system. And a member here send me a full set of good original Pots as spares. Thanks again for that generosity!

 

 

Yeah, I bought L-pads, just wondering whether to install them or not... These speakers will be used with a Marantz 2245 receiver so I'll have tone controls... 

The ALK looks interesting but you can’t adjust on the fly... Hoping the Crites Ti diaphragm will just make the shrillness go away and I won't need any attenuation control on the speaker at all. 

You can damp the tweeter and mid with bits of black gorilla tape stuck to the outside of the wave guides. It doesn’t take much, and you wont be mucking around with repeatedly removing the front panel to make adjustments. The black tape is pretty much invisible unless someone gets up close.

Padding the interior and damping the bass basket never worked for me in my situation. It over-damped and deadened everything. The only other thing I did was to insert a a stick-on vinyl footed 18 lb lead weight through the front ports to rest on the bottom plate of the cabinet. I would try these things before spending lots of money on room correction.

My Klipsch is a Cornwall 4.
