Warm and accurate bookshelves that can handle volume


Hi and thanks for your help. I have been collecting and trying vintage speakers and ended up with B &.W 803 matrix series II, and also Celestion ls700 Se. The latter  are bookshelves and I use them with an NHT SW2 subwoofer. I like them both but prefer the 700s because they more accurately bring out the timbre of orchestral instruments and can be less fatiguing. Troubke is I have a pretty big room and I can’t play full orchestra at realistic volumes on the Celestions without distorting the sound. Are there bookshelves that will be warm, musical and accurate like the Celestions, but can handle volume?  Rest of the system is Qutest DAC, RA LS25 II pre, Adcom GSA555 II speakers. Thanks for feedback on which speakers to try. My reading etc suggests Harbeth Spendor Sonus Faber. Locally have tried kef and paradigm, but can’t get to much else. Will travel to try your recommendations. Seems that satellite and sub will be more flexible and cost effective than tower.

I also love Harbeth but would question them for orchestras at volume. I always feel I start to hear the case resonance limits when I listen to orchestras on them but perhaps a better amp would help as suggested.  

 

I can’t think of any bookshelves that can do a full orchestra well - would have suggested trying b&ws as most likely to work. 
 

how was the paradigm? 

How big is a 'big room' and how lively or dead is it acoustically? Do you have a target peak SPL in mind? Finally, how far is it from you speakers to your listening position? Volume level is a physical parameter that is easily calculated. If your requirements are greater than the speakers capability, the move on. E.g. KEF LS-50s are rated for 104db peak @ 1M and 100W. 2 speakers +3dB, and applying the inverse square law (2X distance = -6dB in level), so sitting 6 ft from a pair of LS-50S your peak SPL would be 101dBA. In a room, depending on size and acoustical treatment, you might pick up a dB or so. Sitting 12ft, lose another 6db in peak level. A larger bookshelf might pick up 6dB in output, and 4-6 dB in sensitivity. YMMV, so do the math  math first to see if you're even in the ballpark.

I go along with henry53. If a system is always warm it's colored . Input varies and the system should mirror that unless you really want it to be warm all the time. It's a valid choice but it's not accurate. You can't have both. You can't even always have smoothness. Some instruments blare like brass and if they don't on a good recording the system is at fault. I remember Gordon Holt was always bothered when a bress recording wasn't in your face a bit.

The Neat Ministra is an isobaric design just reviewed by Mark Phillips at Part Time Audio, and they seem well suited to your needs.  Check his review out.
