Room correction device for SAP Q's;or what??

Hi,everybody. I just bought the SAP Quartettes. I'm running them with a pair of CJ8xs--triode. My problem is there is just to much bass.--These have the side firing 12 in.woofers, in a separate sealed design, cab. I would like to be able to listen at a good volume and not disturb my next door neighbors.---Altho the bass is clean and powerful.---Would one of those room correction devices allow me to cut off /or cut down 'some' of this bass??---Or is there something else for less money that would do this??---Besides an SET amp??--That last line was ment to be humor; as most SETs wouldn't allow this much bass.
