I have had my 904/402 combination for 7 years. Twice I have purchased Jubilee's and put them in the place of the 904's and both times took the Jubilee's out and sold them. I have not found anything that sounds better in my room than the 904/402.

Yes they will just remove the 510 horns and put them in the truck.

As much as they weigh I would have known the difference !

Make sure you listen to it before you put the new diaphragm in it !

Thank You Bruce they are fantastic amps !

You have a PM !

Thanks Mark ! I have 2 more in black if anybody wants one.

Price is $300 obo . XM9 Electronic Crossover Network Steep 24 dB/octave slope. Outputs are always in phase. Crossover frequency choice 10 - 20000 Hz. Subwoofer summing option. Gold plated RCA connectors. No transients during turn-on or turn-off. Fourth-order constant-voltage design. Low-noise circuit design. Available 2-way stereo and 2-way 3-channel. The XM9L Electronic Crossover Network is a fourth- order constant-voltage crossover design that provides both low-pass and high-pass outputs. The slope of each output is 24 dB/octave and, because of the fourth-order design, the high-pass and low-pass outputs of the crossover are always in phase with each other. The crossover network is implemented as a fourth-order state-variable filter. This filter provides both the high-pass and the low-pass function simultaneously, guaranteeing a perfect match of the high-pass and low-pass responses. The XM9L is used between the audio preamplifier and power amplifiers. The two outputs of the crossover network (one carrying the high frequencies and the other carrying the low frequencies) feed the inputs of two power amplifiers, one for tweeters, one for woofers. This is a bi-amplified system (two amplifiers per audio channel). When used with a common subwoofer a sum switch on the front panel allows summing of the low-pass channels. The level of each output is set with a 12 position attenuator on the front panel. The attenuators have 1 dB steps. The crossover frequency of XM9L Electronic Crossover Network can easily be set by replacing the set of 2 frequency modules, located inside the cabinet. The damping control sets the response at the crossover point. In the center position the response is flat. Set fully counterclockwise there is a 4 dB dip at the crossover point and set fully clockwise there is a 5 dB peak. This extra control enables perfect matching of the speakers at the crossover point. When power is turned on or off, a relay grounds the outputs of the XM9 (for about a second after turn-on; immediately upon turn-off) to eliminate potentially damaging transient signals at the outputs. The crossover uses only high grade components: 1% metal- film resistors, 1% polypropylene-film capacitors for the filter capacitors, and four dual FET-input operational amplifiers. Gold-plated connectors for input, output, and power make installation easy. Available options include 24 position stepped attenuators instead of the standard 12 position stepped attenuatorsfor level control. These stepped attenuators are calibrated in 0.5 dB steps and allow very accurate setting of the levels for each output. Balanced inputs/outputs are also available as an option.

I have the original boxes for these so it will be safe to ship !

Thanks Carl !

I was thinking around 200 lbs it definitely takes 2 people to move it !

This is a great sub I have used in my home theater for years. I have the original box but I think it would be too expensive to ship. Price is $750. I live near Dallas, Tx.

Thank You Schu !

I have one in black near Dallas, Tx. for $200 plus shipping.

I know exactly what he was talking about. My point is I never change any of the tubes out in all my tube amps.

I have never changed anything !

I am near Dallas, Texas.

These are very rare ! They are 25 wpc class A mono blocks in perfect condition. Price $2,300

Beautiful pair of Oris 150 horns painted dark blue driven by Lowther PM4A's with AER cones. These operate from 150 hz up to 20 khz. They are very efficient at 108 db 1w/1m. All you need is a bass system or subwoofer to work below 150 hz.. It really is magical to hear a Lowther PM4A in a front loaded spherical horn. With a good SET flea powered amp it is as if the performers are right there in the room with you. The Oris give a very holographic image. I have stands, phase plugs and crowns for them.The Oris 150's are the blue speakers that are pictured. I have had a few inquiries asking if I would sell the horns separately. I will sell the horns and drivers separately. One driver has a bad surround but I have the replacement for it included. Horns with drivers $1,700 Horns only $1,000 Drivers only $700

I have 3 but they are all black.
