Bookshelf speakers for small room

@labelman - the Super Alnico Monitor is probably the ideal model for your situation.  The proprietary Alnico driver Omega has developed is something special - super quick, extremely rich tonally, detailed without being fatiguing, very "lifelike".

Louis at Omega is a great guy to work with and would be happy to talk to you about your situation and either recommend something from the product line or do something custom for you.

I’ve been very happy with Rogers LS3/5a speakers in a nearfield setup.  They sound great at low volume levels, and scale very well.  Currently running them with Rega I/O 30wpc integrated.  

Love these recommendations.  Is there anything within the smallish footprint of the Martin Logan 4s that I have?  I really don't have any floor space and little desk space.

Harbeths are great speakers and it appears the P3 is a real gem according to many. With a cheap thousand dollar SVS SB-3000 you'd have full range with a sealed tight sub, and the ability on the fly (via remote) to adjust for a customized loudness setting for low level listening.

Otherwise I think you must have a loudness or bass level control unless low level bass is not desired. Bass drops off tremendously at lower levels, at least what is perceived audibly. I don't think the old loudness controls were designed for bass-heads; they facilitate more enjoyable low-level listening.

And if the budget is truly $15k I'd sure be shopping a lot more higher end bookshelf speakers as well. I know some who like 15k of electronics hooked to 2-4k speakers but that's pretty low bang for the audio buck IMO. Start to seriously blind audition electronics and see what you can really hear or identify. It's usually not much when compared to a loudspeaker upgrade will provide for your money. I think many of us forget what makes the single most difference audibly...

As mentioned, this is a great project so have a lot of fun and good luck!

For small rooms and near-field listening conditions, the Kef LS50 is an easy recommend. The coincident/coaxial driver design provides a single point source of sound and excels in close-listening situations. I also listen at low levels (SPL) and am very happy with my choice.
