Depends on your preferences and budget. I have a pair Revel M126Be standmounts that sound excellent with my pair of SVS SB1000 Pro subs. They have a rear vent that can be plugged but I removed the plug. I preferred them over KEF R3 Meta, B&W 705 S3 and SVS standmounts.
Bookshelf speaker pairing with subwoofer
I have a pair of REL Ti9 subs in my dedicated listening room which is 12 x 17. I am looking for a pair of bookshelf speakers that would pair well with the subs. Searching on my own and watching reviews has made a choice even worse. So many to choose from. I mostly listen to jazz and blues with some classic rock thrown in. I have a good SACD collection and several dsd files. There are no audiophile stores close to me.
Any input would be appreciated.
