Dayton Audio SA230 230W Subwoofer Amplifier
What, internally, is different about this standalone amp versus the plate amps that are $120 less and with 10 more watts? Are we paying more than double just for fully adjustabe phase adjustment? I really need 0-180 degrees of adjustment, but I can't understand how I can buy two of the comparable plate amps for the same price. Will Dayton design another plate amp around 240w with fully adjustable phase control ever again?Does this standalone amp have better components than the plate amps?
A summary of the differences is thus: the SA230 includes variable bass boost and frequency, fully adjustable phase, LFE input, and 12 Volt trigger. The SA240 plate amps do not have any of these featuresThe 12V trigger can be considered superior to the auto-on feature (in the SA240) because auto-on may not detect a low level RCA signal, or may "lose" that signal, and disengage the amp during long quiet passages in movies or even music, where the 12V trigger is activated by the switched output of the receiver, so it turns on and stays on until the receiver is turned off.A table top amplifier allows you to conveniently power more than one subwoofer from a single amp, and also eliminates the leaking of air sometimes associated with plate amps, as well as the volume displaced by the plate amp, ultimately allowing for a smaller, more compact subwoofer.The SA240s do allow for high (speaker) level inputs, however, this is not the connection method of choice, so it is only used when LFE or pre-amp output is not available from the source (which is more and more scarce with modern products).I cannot speak to pricing, sales, or what kinds of products may (or may not) be in development for future release.

Is specified RMS power rated per channel?
I see the amp is rated at 156 watts into 8 Ohms. Is that watts per channel or in total?
This is a single channel amplifier so it supplies 156 watts x 1 into 8 ohms or 230 watts x 1 into 4 ohms.

would this amppower 2 subs in a stereo set up on a open baffle speaker with active bass subs with 2 TC epic 12" woofers
Assuming you are using TC Sounds DVC Subwoofer part# 293-650 in the Parts Express Catalog, then this amp would work IF you wire the dual voicecoils in series for a 4 ohm load per speaker and then wire the 2 subs in series for an 8 ohm load to the amp. Otherwise, you would place too low an impedance load on the amp. It would handle the 8 ohm load just fine. If these are not dual voicecoil subs just make sure that the load on the amp is NOT below 4 ohms! Hope this helps.Randy

will the sa230 push 2 VP1800's ?
LOOKING FOR MORE BASS AT LOW VOLUME, I have a HK3490 with 2 VP1800's and 4 VS1520's plenty of bass at higher volumes , need more bass at lower volumes
Your question is very conflicting. Clubs use variable EQ for small audiences all the way up to large audiences due to the way their bodies effect frequency response. You should study the Fletcher Munson curves to see how we perceive low frequences at different SPLs. As for the SA230 running dual CP1800s - that's not a good idea. You will be compromised with impedance issues and there won't be enough dynamic headroom to delivery optimum perfornmace.

Does the SA230 have a Subsonic Filter?
All Dayton Audio subwoofer amplifiers have a subsonic filter at 18Hz.

Would this amp adequately power the Dayton 10" Titanic?
Yes, it will do a fine job with the 10" Titanic in a small to moderate size listening area. In fact, the SA240 comes with the Titanic 10 in our subwoofer kit for that speaker. The difference of 10 watts is negligible. I've linked the kit below for reference.
