Which speakers for McIntosh tube amp MA2275-Why?

My room size, hard wood floor, is about 26 feet deep 30 feet wide. I cannot place the speakers to benefit from the 30 feet and there is too much furniture in it. I feel that it interfere with my tone. When I moved it will be a different story:)

I know that it might be possible to buy some vintage Tannoy Autograph with wooden horns to be placed in corners. Is this what you have in mind?

My wife could likely live with 15 speakers but no room in the corners

My room cannot accomodate such large corner horns. Also they are 15 inches and I would be afraid that they might be too heavy to have fast transient and well defined bass. Also how does a 15 inches cope with its upper range? After all these coaxial speakers are only 2 ways and are supposed to be wideband.

Thank you

How does the forum work? I tried to reply to the answer from Peter_S (large corner horns)and was expecting to see my reply under his answer but I got it at the end just like if it was an answer to my original thread. How can I reply to a specific guy?

Thank you,

To Lokie. Talking about impedance dip. This is the type of info I am looking for the preselection even if at the end my ears will decide.

As a pysicist I studied topics related to amps and speakers a long time ago and worked on more exotic stuff since then. I am afraid that I forgot many things...age doesn't help I guess...

If someone could explain the difference of behavior between ss-amp and tube amp when it comes to variation in impedance that could be interesting. I heard that for tube amp it is better if the speaker has a positive phase angle than a negative one. Is this true? Why?

My MA2275 has large output transformers, my feeling is that the stored magnetic energy should make my amp less sensitive to dips in impedance than a SS amp as SS amp don't have the large energy reservoir. What is wrong with my reasoning?

I have on my MA2275 2,4 and 8 Ohms output; it is the magnitude of my impedance. Is my amp output purely resistive or reactive? Does it influence how well my speakers will match, how they will behave?

Thank

To Lapierre Audio Note AN-E SPe HE. These speakers are 98 db efficient in rather small cabinet or at least not that large. I doubt that it has the bass extension suitable for pipe organ. Also the cabinet is lightly braced with little damping as it is supposed to ''supports the drivers in their task, not unlike the box of a guitar''

It would be a very difficult task to tune a cabinet to help the drivers and ending with low coloration and artefact. I am not sure that I would trust that.

What is your experience with this product?

I would better trust JM lab or Dali

Have a nice day

Klipschfan made a stellar advisement. The LaScala II is just about as efficent as a speaker gets, and has midrange that will knock your socks off. Paired with a great sub from JL Audio will give you the depth to deliver the pipe organ in spades. Excellent suggestion, especially paired with the McIntosh tube amp.
