10" self powered sub-woofers.....


I was using an NHT B10 d to supplement the bottom end of my Acoustat 100 hybrid speakers...  electrostatic panel over an 8" woofer module.  Due to the unexpected death of one of the subs in our living room I decided to move the B10 d there, to augment an NHT C10, and replace the sub in my listening room/office.
Since I've had good experiences with Stereophile Recommended Components over the years I decided to look up their recommendations on 10" subs and found a Martin Logan Dynamo 800X which is a 300 W 10" sub with ARC and phone app controls. It also meets the maximum width of 14.0" I have available for it.  The other alternative is the also recommended JL Audio E110 at about double the price.  Since there really aren't any salons in Miami to go listen to this gear being able to return it after 60 days or thereabouts if it doesn't work as contemplated is essential.  I can get the ML from Music Direct or Amazon... probably Best Buy too.
Any other recommendations are welcome as long as they meet the 14.0 maximum width criteria, are self powered and designed for music as a primary application vs. home theater explosions.
Thanks

Your "leaning" certainly makes sense to me. I’ve a high regard for Music Direct given several purchases from them and a couple no hassle returns. Don’t think you can go wrong buying there. Good luck!
@ghosthouse4 thanks again... I have a test track for you as well. It has some lower guitar notes and an organ note the NHT B10 d could not handle, the C10 did better but not decently. It’s on a Patricia Barber album, "A Distortion of Love", 24 bit FLAC on Qobuzz, I suppose Tidal has it as well. I believe it’s on cut 1, "Summertime", but without a sub in the system today I can’t tell you where it is time wise in the cut as the 8" woofers in the Acoustat modules simply didn't acknowledge it’s existence. While they do a fabulous job fleshing out vocals and instruments below the panels range their ability to do bass fiddle and low organ notes is somewhat (LOL) compromised. They were rated -3db at 30 hz when new three decades ago and could use help down there now, especially with by a sub with contour controls. The ML is rated 24-200 hz with controls for +/- 10 db @ 20-30Hz Level. The B10 d was rated -3 db @ 29 hz and the C10 was rated @ -3db at 22 hz. I’m going to sleep on it tonight but I seem to be convincing myself that ML from MD is right for my application.
FWIW, I have had Rel Subs for over 15 yrs with no reason to move elsewhere. Some talk about its lack of 20 hz bass and its expense. I just know it works for me, a drummer who LOVES a good bass line more than most. I can't say the others are inferior. But I KNOW how easily the Rel's integrate and how they add, not just bass but expand the whole musical range. The T7i or T9i will work, except for the depth which is 15".

Use 4 of these. Each one in a 12 CF box. A 1000 watt plate amp per box aught to do.

ADD 4 to the cart. :-)

Boom Boom in the Room Room and WAVES in the neighbors swimming pool. Bigger :-)
