Best Bass Amp!

Thanks everyone for the suggestions on the amps & subwoofer layout ideas. Much appreciated! 

Regarding the amps, I have a pair of PSA M700’s already on the Dali Megaline woofers so I will most likely try them when I’m done working on the Kinergetics subs & buy another pair then since I can get them for <$2K new.  I just wish they had an auto on/off feature or always on like the Bel Canto or Wyred 4 Sound amps. I may try a used Krell, Parasound or Bryston someday in the future though since they both have a great reputation for excellent bass.

 

Regarding the subwoofer layout Distributed Subwoofer Array vs Line Source Vertical Array I don’t pretend to be an expert, but I’m sure each have their pro’s & con’s. Since my room won’t permit DSA arrangement & I’m mostly concerned about the sweetspot vs the whole room getting the best bass. Besides, isn’t twelve 10” woofers better than four 10” woofers for room coupling? I also feel a subwoofer system that matches the height of my 7’ Dali Megalines will blend better together. Also, one of the world’s best speaker system the Infinity IRS uses LSVA & all other high end speaker manufactures do also.

Here’s a link to some very interesting reading about different subwoofer array designs:

BTW- My Kinergetics SW-900 are very rare(only on I’ve ever seen, ever!) vs SW-800. The SW-800’s have five 10” woofers per side & measure 58Tx13Wx16D & are MDF with most oak veneer vs my SW-900’s have six 10” woofer & measure 70Tx13Wx19D are HDF with beautiful walnut veneer. I can’t wait to get them setup!

Advantages of Vertical Line Arrays:

Preventing Drop Off With Distance – A major advantage of a line array system is that you can achieve much more consistent sound levels from the front to the back of the listening area. Line arrays are made up of multiple modules, so by adjusting the physical angle and the amplitude of individual modules, a higher sound level can be projected toward the back of the room than toward the front, resulting in more consistent coverage throughout the space.

 

Vertical Pattern Control – The taller the line array, the better the control of the vertical coverage of the low frequencies emitted from it. This is important, as it reduces how much sound is sent toward the ceiling, which can cause unwanted reflections back into the listening areas. They can also reduce the amount of sound that leaks onto the stage or chancel area, which in turn, decreases the level of sound regenerated through open mics on stage, thereby cleaning up the overall sound and increasing GBF.

 

Sound Pressure Level (SPL) Capability – Some line array systems have a large number of drivers inside each cabinet of the array, allowing a single coherent wave front to be produced. Because of all these drivers, line arrays often have the capability of producing a higher SPL than is required, enabling systems to operate well below their stress point. If your church’s worship style requires concert-level sound reinforcement or hosts visiting national acts, the SPL capability of certain line array models can be an advantage.

ptheo,

     I misunderstood.  I thought you were looking for high quality bass performance that is very articulate, natural and integrates seamlessly with your Apogee Stages or your Dali Megalines but is still flat down to 20 Hz.      You've made it clear you're more interested in high spls and high quantity of bass rather than high quality bass. 
     You're obviously not familiar with high quality bass in your system since you'd rather sit in front of a pair of arena rock concert bass towers.


My mistake,

I didn't realize they produced a 900. I own 800's that I was gonna use for a 2nd system that is not gonna happen so unfortunately will be selling them
They were designed to mate with Martin Logan CLS mains I believe. They produce quick, tight and deep bass! I ran a Crown XLS1502 amp on my 800's and Dspeaker anti mode 2.0. You could also look at Speaker power sub amps.
Please post pics if you can.

@noble100 Eeeewww!!!!  Can you make your point without being mean or rude? Please don’t bring down this website!

peter-s,

How was my response rude?
This is a forum meant to discuss audio and ht issues in an effort to help members optimize their system’s performance. The accumulated knowledge and experience of Audiogon members is substantial and is willingly shared with others that require assistance.
I happen to have significant knowledge and experience gained in my many years of attempting to attain very good bass performance in my system, in my 23’x16’x8’ room that integrates seamlessly with my large Magnepan panels that only have useful deep bass down to about 35 Hz. I’m thrilled to have discovered a bass concept that provides sota bass in my system and room for both 2-ch music and ht. It’s called a distributed bass array (DBA) system which I’ve previously described.
When I read ptheo’s initial post stating he was searching for a pair of good sub amps he only mentioned that he used 2 high quality pairs of speakers. Apogee Studio Grands and Dali Megalines. He made no mention until subsequent posts that he intended to use a pair of large SW-900 tower subs with his very good main speakers.
I mistakenly thought, based on the quality of his two pairs of main speakers, that he’d be interested in a DBA bass system that would allow excellent bass response to the known excellent mid/treble response of both of his main speakers.
My intention was to assist ptheo by going beyond just offering suggestions of good bass amps and offering a bass solution in the DBA that I thought he wasn’t aware of and that I knew would integrate sota bass response seamlessly with either pair of his very good main speakers.
Unfortunately, I was surprised and disappointed to learn from ptheo’s subsequent posts that he clearly preferred increased bass volume and quantity to bass quality.
My perspective is I simply stated this without any intention or evidence of rudeness.
If you or ptheo perceived my previous post as rude, then I apologize and assure you that wasn’t my intent.
