Speakers with deep/powerful bass

Just buy some Svs 4000 or ultra subs they will go lower and with more impact 

with their high current amplifiers built in and 13-16 inch drivers 

buying 2 will balance out the rooms Bass.

Most speakers mentioned here has Non accurate bass big rounded bass altec Lansing cerwin Vega , Klipsch , these speakers at best upper 30 hz 

that’s why i mentioned  a good quality powered sub woofer if that’s what you want 

this will enhance most speakers unless you have  over $20k+ for upper quality speakers. I am torn from a decent say marten oscar trio which will do quality bass to around 30 hz , or buy a great stand mount such as the. MBL  126 stand mount with matching stands , and just buy another Svs SB 4000 sub . I have all year to ponder this for these are all in the $15k + range , I have to save my Pennies.

What is your budget  these cheaper speakers have bass but it’s far from bein tuneful and accurate , bloated is a good way to describe vs even a goodsubwoofer like a Svs 400; Rel anythjng over $1500 in a sub will be more accurate 

in a speakerover $10 k for quality drivers , please remember only 25% on average goesinto thespeaker this includes all packaging ,the rest R&D overhead and markup..
