Speakers with deep base

Looking for a speaker that will do deep and abundant base. Must have, at least in my view, at least 12''+ drivers. Thinking 5-7k in budget.

My room is 20 feet wide and 60 feet long.

Other restrictions on gear are really not an issue. I can buy what I need.

Thanks Ken

In that case,go to a dealer and buy everything you want at once, after auditioning of course.
Eggleston Works Andra II's (haven't heard the III's -- these beging the newer versions are not in your price range).

any of the Wilson Audio speakers, or higher model B & W's, they have great bass.

that would be my first suggestion, and you can also find Watt Puppies, used, in that range as well.

Great bass from these speakers. I don't know what the ratings are, but when I have heard them, they go DEEEEP!

Tvad, thanks for the follow up.

Slightly used Legacy Focus meet your requirements. Either two or three 12" woofers per speaker. (The older models have three per speaker, the newer ones two.) 95db/2.83v efficiency, so your watts go a long way. I don't know of any other speaker that moves as much air for the price, without a dedicated subwoofer. Pretty good sound overall.
Legacy Focus 20/20 or Focus HD (earlier versions had loose bottom end IMO -- 20/20 and HD versions corrected this). Big sound with abundant bass and good musicality -- very dynamic (both need strong solid state amp to control the woofs--pair with a good tube preamp and this is wonderful rig).
Vandersteen 5A will perform true 20 hz bass in your room
They feature a self powered double cone metal 12 in a sealed enclosure with a unique tuning feature that will optimize the quality of the bass in your room this enables the mid bass,patented mid-range, and treble drivers to sit on a bass coherent foundation allowing you quality performance and coherence at all volumes.
A speaker with a really deep bass, then look no further than a B&W 801 Nautilus. I have had the B&W Matrix, Series 3 and 801 Nautilus. Matrix 801 had pretty good bass with a 12-inch driver, but the 801 Nautilus was really something else with a 15-inch driver. The 801 Nautilus' bass was incredible and amazing. The bass strings on jazz recording really come alive...

I have auditioned Wilson Watt Puppies many times. They have pretty good bass, but not as powerful as the B&W Nautilus 801. Now if you are looking more for quick dynamics and transparency, Wilsons are hard to beat.

I have since moved on to Avalon speakers, but still miss the bass on the 801 Nautilus I used to have, and not by a little but by a lot!!!

Be careful what you wish for! If you had a graph of a speaker that had "abundant" bass then it might appear (and sound ) like the highs were rolled off.

Easy answer: B&W 801N or the original Revel Salon, both available within your price range.

The B&W needs to be bi-amped to sound right - it requires an enormous amount of power.

The Salon can go incredibly loud with really high quality bass, and also requires a lot of power, but doesn't require biamplification. If you like 4th order crossover speakers, it is hard to beat, and at used prices, it's an enormous bargain, as it is an excellent speaker.

Large drivers are not necessarily needed to achieve deep, prodigious bass - the quality of the drivers and their implementation is what counts - but yes, larger cones are generally better.

How high are your ceilings? Do you have concrete floors? I have a room half this size and I have trouble making bass but I have 10 foot ceilings and peer and beam wood floors.
Start with multiples of JL Audio F113 Subs then add what you want from there.
The ability to produce "deep and abundant" bass in a room is a combination of the speaker design/performance and the room design/performance. At one point some years back, I had Vandersteen 2CIs in an 18' x 35' room with a cathedral ceiling and the bass by far exceded that of my friend's Vandersteen 3A Sigs with 2WQ subs in a 20'x 20' room. Keep in mind that you need to explore more than just the speaker to achieve your goal.
Well there are lots of speakers but new speakers in that price range that can do deep bass will most likely have lots of compromises in other areas. I would buy used.

An often over looked speaker line for there bass is Thiel. There is a pair of Thiel CS7.2 for $6500.

Fallowing quote is from Soundstage!

"The CS7.2’s bass
depth and authority are shattering, and its bass weight is wholly
realistic —not warmed up to create a sense of fullness or heft from
recordings that don’t have it by nature. Bass notes are carved
out with exceptional clarity, even at the speaker’s very depths.
Claims of 20Hz bass are common today, but if the CS7.2’s 25Hz
low-end specification is correct, many speaker companies are exaggerating. From my experience, you have to pay several times the CS7.2’s price to rival its deep, linear bass."


"Thiel speakers are known for excellent bass, but the CS7.2 was even better than I'd expected. From the mid-20Hz range on up, it was fast, clean, powerful, and very natural—in other words, dead on. Detail was excellent, as was the recovery of ambience and spatial cues. On "Saturn," from the Zubin Mehta/ LSO reading of Holst's The Planets (London/Classic CSCD 6734), I could clearly hear the individual double basses lined up at an angle. The walls beside and behind them were solidly located, and there was a great sense of the space between the instruments and the walls.

Fast, melodic bass lines—Ray Brown's Soular Energy (Concord Jazz CCD-4268), for example—were sweet, clean, and bouncy. But what really struck me was the 7.2's reproduction of bass drums, and the breathtaking drive and impact that it added to orchestral pieces. My notes on the second movement of the Reiner/Chicago performance of Prokofiev's Lt. Kijé (Chesky RC10) say it all: "Wow—incredibly realistic, with a fast initial transient followed by a seismic, blooming weight . . . all the while maintaining a clear pitch, harmonic structure, and distinct skin tone. Fantastic! I've never heard bass drums like this outside of a concert hall."

The only nit I'll pick is that the 7.2 slightly emphasized the very lowest bass relative to the upper bass and lower midrange. This didn't come across as an imbalance or discontinuity, however, but as if Ray Brown just wasn't playing quite as loudly at the top of his range as at the bottom."

I am really looking forward to the CS7.3 that is coming out down the road...
If you are looking for low extended deep Bass, I would highly suggest a Bass reflex design (B&W etc;) or sealed enclosure (Hales etc;) with nothing under a 10" driver IMHO.

Your room dimensions are approx. the same as mine. I hope this helps.

Good transmission line speakers wil do the job without the need of extensive power.
By the way, .mind your ears!
Pick a pair of floorstanders that you like, and add a pair (or a stacked pair on each side) of JL Audio E112 subs using the crossover built in.  Cross over at around 80hz regardless of speaker size (don't just add them in where the mains roll off) and you will have better bass than almost all stand alone speakers made if done right.
You guys think he found a pair of speakers after seven years?

Holy thread revival Batman!!!!

This guy knows MANY people read these old threads "cuz they  apply to their current situation , that's why its polite to tack something on if its relevant .
Good luck! Towers with sub woofer rules the industry now! 1970's rock and roll bass thumpers don't exist anymore!
