Speakers for Manley amps

IMO you are going about this bass ackwards.

OMG - you are violating the playbook! 'Nothing at all wrong with having your eye on an amp first.  Relax and enjoy - pick whatever you want in whatever order you want; OCD posters notwithstanding...

IMO you are going about this bass ackwards. Pick your speakers and then pick your amp to match. Just my opinion...

Tannoy!!! I have used Snapper and 300B monoblocks and they both drive Kensington and GRF easily. 

@esputnix What Manley amps do you have?  I like the look of the 300B monoblocks.  Anyone he any experience with them?

Legacy sounds fantastic with them

Tannoy GRs.  Your work is done...

Emerald Physics open baffle speakers should be an awesome match. They are very efficient and an easy load to amplifiers. They should sound magical with Manleys

Joseph has often been shown with Manley 

MAGICO A3s would sound wonderful.

I know for Eveanna Manley uses Tannoy’s with her Snappers.  Might be good place to start. When I had my Snappers I used them on a pair of B&W Signature 805’s and later on my Proac D-30R.The B&W’s worked well with the Snappers but things really improved when matched with the Proac’s. The Proac’s are much easier to drive and I was able to run them in Triode mode with little loss of dynamics.The mid-range and sound staging were sublime.

The Snappers are great amps. Hope your enjoying them.
