I am useing Polk Rti8 for fronts,

and a SVS PB12 Plus X2 for my sub crossed at 90hz via HTR6190 receiver.


I want to fill in the 90 to 300hz that I feel is missing in my fronts.


I bought Rti10's to replce the 8's ....after the last 2 days of back and forth with my wife, we can't seem to get the missing midrange back to our satisfaction.. could get a Bigger dedicated Amp, MAYBE that works.

the Bass in the 10's is great.. but they're boxed back up and going back.

Now.. Can I build a box and buy a couple 7 or 8 inch woofers and bi-wire them to run with my 8's. ?

Or Can I buy 1 or 2 High quality 6"-8" subs earthquake or Sunfire ? to run at the 60-200 hz ? corner mount them next to each front ?


I Really appreciate any help or past experience anyone has trying to achieve a similar thing. Filling in a gap I now notice after doing A B with two speakers both having strenghts and weakness.. I actually thought of 4 fronts.


But a 11'6" x 20' room 7'3" ceiling all sealed up, pretty small in there with 2 rows of seats etc.. feels smaller.

Thank you..

hmm.. looks to be really good, is 150hz high enough.

I'm not an audiophile, but I figure after some playing around it is the 80-250hz area I'd like to cover.

I could be wrong ?

Where does a typical shot gun blast impact fall into... 150-200hz for the most part. ? My guess.

actually.. On Tudors HD, I was watching a scene with a Fireplce going.

Sounded very real and up front in the sound with Rti10's

with Rti8's almost non existant by comparison. doing a A, B, switch last night.

That was around the 100+hz because my SVS wasn't filling in after I tried it with it turned on with the 8's.

Now I want that 80 - 200hz ...I think??


ps.

Frt Speakers set to large, Bass out set to to Both,

If I set to small I hear NO difference.

 Danley TH-Mini


It will start to roll off above 250hz. Has "adequate" output (131 db) and incredible sound quality. I sell them.

I'm Ordering 2 HSU Mid Bass Modules Monday 9am.

Front right..front left.. 10 feet from front row seats.


Moved my SVS PB12Plusx2 to the back of the room behind the second row of seating on my riser,,,,,Now my row of seats Shake Like I have buttshakers attatched.


My PJ ae3000 is shelf mounted above, I hope the PQ is Not affected with ALL that shaking/vibration.(my ears hurt, not kidding) I had to test is Loud to make sure.


After the MBM arrives, I can tame the SVS from 100hz to 70hz and dial vol. down.. maybe that will do the trick.

I'll use the Avia disc to blend the 3 units. with the fronts and ctr ch.


Anyone who wants to see pics or hear how it blends can PM me and I'll forward what I can.

Stevegamble66, I have the same dilemma as you, looking for a mid-bass solution around 50/60hz up to 100hz or even 120hz to take over my DIY TC Sounds 15" sub, awesome to about 60hz but then it drops off quite a bit and my speakers being on the small side (Mirage Omnisats v2) sound good but do not give me the mid-slam I'm looking for. If I buy one of these Hsu MSM 12" subs, it would have to go also on the front. The question I have is that it would have to go on one of the cabinets of my big pine wall unit, 18"w x 20" D x 26"H, would being in an enclosed cabinet (only the door open) effect the sound of the Hsu MSM sub since its ported?

I am surprised that those particular speakers are not providing ample performance for you in that range. I assume you are running them as SMALL with that 90Hz crossover setting in your receiver and you have either bypassed the PB12+'s LPFs or have set them as high as possible. Have you tried lowering your receiver's crossover setting?


90 to 300Hz is not "midrange", btw.

Always forget about this one...

There is also the Danley TH-28. 47-162 hz. Tapped horn design. Will do 129 db.

Measures in at 20 x 30 x 10.5 in so it can be used under a center channel or set on its' side. Same unparalleled Danley Labs sound quality. Same price as the TH Mini ($1295).


Last but not least, the JTR Growler. Infamous midbass woofer. Several forum members here got them from me. 45 hz to 125 hz so it is a true midbass design. 30"x20"x22.5" so it isn't small, but very potent and the lowest priced truly potent midbass sub at $995 (yes, they went up).


You'd need about 6 or more MBM subs to match the output of one of any of the above so headroom isn't a problem.

In a similar but different way.. I had to put my sub like that, to make room for two comming HSU MBM.. today tested.. sound 90% same..meaning I have the same output, and 90% fills the room in a even,, enveloping way at low volume. at High volume I can't tell the difference.

I think being that MBM are intended to have a somewhat directional sound field, that set up would work. Port facing outward of course.

Anytime you get above 80hz the sound becomes more SOUND and gets more linear.. IMHO.

No 90-300hz is not midrange, It is ( Ithink) upper/mid bass ?


I have speakers set to large or small I change it week to week, I hear NO difference either way. Bass out set to Both, crossover set to 100hz somethimes 90hz.

EQ boosting 160hz and 400hz a lot in the Fronts Rti8's.(or trying)

The 10's have WAY more bass, but WAY ,WAY less midrange in the 250-1khz area. Night and day dif.

Now I hooked my 8's back up for that in your face up front +8db louder 300-1khz ....but after dissconecting the 10's miss the bass they had.
add 2 mid Bass modules right side and left ??

I'm going to take a series look at Danley TH28 before deciding.

performance cost Value looks better, although I need to know for neutral sounding HT use ? The warm sound to extend the dialog to lower frq. etc. ?

I'm going to do a little digging.

Anybody here use this for HT use ? to accent a True sub.. ?
