Klipsch KPT-1802-HLS 300lbs Of Horn Loaded Sub

Times have changed and the really big hi-fi speaker components are in cinema lines instead of consumer lines because people today mostly want to hear their iPuds or whatever plugged into their whatevers. They can have their whatevers stuck in their whatevers. I'll take that old timey cult of hi-fi big honk'n multi horn systems.
 
The really fun stuff is tucked away in the cinema lines of companies like Klipsch and Jbl just to name two. Klipsch has really interesting bas bins including this one from the horn meister himself Roy Delgado. I understand he has a patent for this one but I haven't looked it up yet. This one is a stunner. 
 I know what your thinking... It looks like an MWM but it performs much differently. Let look at what Klipsch has posted about this beastie.


The Klipsch KPT-1802-HLS cinema subwoofer uses a patented, horn-loaded vented cabinet design with an 18” driver, resulting in class-leading acoustic output combined with commanding sub-20Hz bass response previously unattainable from even a 21” driver configuration system.

An industry-first horn-loaded vented cabinet design
High-efficiency with very low distortion perfectly complements today’s digital sound formats
130dB continuous output capability


Frequency Response:     26Hz-240Hz +/- 3dB; f10: 21Hz-500Hz -10dB (3M, Half-space anechoic)
SENSITIVITY:     100 db @ 2.83V (SPL at 1M, half-spaced anechoic with 2.83 volts input)
POWER HANDLING:     1100W (93V) 26Hz-250Hz (AES standard, continuous pink noise, 6dB peaks)
MAXIMUM CONTINUOUS OUTPUT:     130db 25Hz-250Hz (Calculated at 1M half-spaced at power handling power input)
NOMINAL IMPEDANCE:     12 ohm (8 ohm min.@100Hz)
ENCLOSURE:     Horn-loaded vented system (US Patent 5,898,138)
ENCLOSURE MATERIAL:     ¾" Plywood
TERMINALS:     Barrier Strip
DIMENSIONS:     72" (182.9cm)W x 48" (121.9cm)H x 31" (78.7cm) D
WEIGHT:     300 lbs (330 lbs shipping)
 If  ever get another hi-fi room. This could be the start of a crazy multi horn system.

The hard part of obtaining horns like this from a cinema line like Klipsch or JBL is finding a cinema dealer willing to work with an individual to get pro items. It is possible though.

This is as the teenage girls say  AMAZEBALLS TOTES MA GOATS!

What to look for when buying Stereo power amplifiers - 1959 Hi-Fi Review

Hi-Fi review examines 5 really nice amplifiers of the day. I have the Knight so their comments about it are really interesting to me. I'm rebuilding it this year to use on the bass section of my next horn system. It should be fine for that duty. If I could pick one out of this list it would be the Leak. Always wanted one.

What is it? Sanborn?

I went to a small auction at the Klipsch factory where proceeds would go to restore some of the items in the Klipsch Museum Of Audio History. I bought many items but only one did I have no clue what it was. 
Any idea what this is?
What was it used for?
 
The logo is very cool and the knobs are stylish.
 The unit is modular in construction. The power supply has hints as to what it is but I do not know.
The unit has many tubes 6v6 6SL7 12AU7
 Anything worth scavenging in this whatever it is?

Music For A Snowy Day

We finally got some snow this year. I like the way my black bamboo holds some of it.

This is what is spinning now. I'd love a cleaner copy of this but this is one of my favorite records.

Get Your Retro HiFi Thong Here... What?

I only vaguely remember setting up a cafe press store years ago . The only thing I remember is that I wasn't happy with the end result. The question is why did I set up a thong. I can't fit into one. Now I don't care who you are this is funny. Like anyone who reads this blog wears a thong.... HAH... Perhaps we will have a HiFi thong photo contest.

Desmond Dekker - Hippopotamus

 This is what we are skanking to today. I like this slower more skanky version. Desmond Dekker is one of my favorite original Ska artist and he always had a hot band backing him.


The flip side OO7 shanty town

This is one of the few vintage live clips of Desmond Dekker I could find.
