Loudspeakers that go LOUD?


I recently finished off a basement room that is 24.5' x 22.5' x 8'. My beloved Tyler Linbrook Monitor Signatures sound as wonderful as ever there provided I reign in the volume control somewhat, otherwise the SEAS Excel 7" drivers start to protest. I'd really like to find some speakers that wont give up too much in quality, especially in the areas of treble refinement and in imaging, but will play loud without strain. The few horn systems I've heard sounded peaky in the treble to me, but perhaps there are some which don't. Suggestions will be gratefully received.

Parameters: For music I am into classical, opera, female vocalists like Eva Cassidy and Jennifer Warnes, movie sound tracks, shows, golden oldies, but no heavy rock or metal. Power is via a 50 watt/channel tube amp but that could be changed out. Budget: on the order of up to $3K new or used.

Your speakers have a sensitivity of 92db at one meter. If you were sitting 12 feet away that would translate into 83db at the sitting position with approzimately 2 watts since this is a 4ohm speaker. At 32 watts of power the sould level at your seat would be 95db. Your amp probably delivers more into 4ohms and I would guess clips gently in the mid 70 watt range into four ohms. Giving you at least 98db of volume at your seat. 98db is very loud. You couldn't stand it at that level very long. Most people actually listen in the mid 80's range.
Your amp is fine. Don't worry about that. Since you love your Linbrooks I would suggest you buy the Linbrook bass modules from Tyler. You could get them to match your monitors and the pair sell for $2,400. That would relieve the strain on your monitors and give you much higher sound levels in the bass range. They would look great, everything would match asthetically and you would get the sound pressure level you wanted.
Look into Tyler Acoustic PD80s with the built in sub amps. Your 50 wpc amp will only drive mid/highs. These horns are NOT harsh or squawky.
Find something that you can bi-amp and use the tubes for the upper end and buy yourself an inexpensive powerhouse for the bass (Adcom, Parasound or Rotel are a few)

I did this with Innersound ISIS and they played loud and didn't lose the imagery or soundstage
These are a tough load for a tube amp...change the tube amp for an SS amp with 250+ WPC and your beloved Linbrooks will sing....
Switch to a solid state amp and try a pair of VMPS RM40's that can be had for around $3k used. VMPS are very efficient and have a huge sound stage and window rattling bass. I love my Zu Definitions; they get very loud and your 40 watts of tube power is more than enough with the Definition's 101db and internal amp controlling the four, 10 inch wooofers on the back of each speaker.
