New DIYSG speakers: HTM-12 and HTM-10

Thanks Erich and Matt G for developing and posting these. Very much looking forward to seeing measurements. Looks like 2 great low profile options.

I was wondering if a thread was going to be started for those. They look really interesting

> 1- 10" Eminence Deltalite: $
1- Denovo DNA-325: $69.20
1- Denovo SEOS-15 waveguide: $28

seems odd to use the SEOS-15 w/a 10" woofer, esp if compactness is a goal

I bet its a typo. The horn cut out in the pic does not seem much wider than the woofer cutout in the pic.

Figures!

Finished my Fusion 10's two months ago and... kidding, the F10's fit my requirements better for width.

They look to be a 10" with 12" SEOS horn with a shallower cabinet for mounting behind screens? The 12 version is a 12" with a 15" SEOS horn crossed at 1400Hz very wide but shallow again.

Pretty cool, they are shallow enough for wall mounting along the lines of the 88 Special. Also of note is the 1" thick MDF panels--nice!

I am looking into getting these! the HTM10 - I think the info is being adjusted, so maybe check later. I believe the HTM 10 is SEOS 12 and then HTM12 is SEOS 15?

Eagerly awaiting final pricing

The 10" Deltalite goes with the SEOS-12, it was a typo because I was working on the page too late at night.

The newer designs are geared to fit better for dedicated home theater use. Lots of people ask if speaker 'X' will sound okay when used with speaker 'Y'. Or that they have plenty of room for width, but not the depth. Or what kind of stands do they need to hold a 75lb speaker.

So the goal for the new speakers:

One designer knocks out the whole line up and voices them to sound nearly the same. That way you can mix/match for center channels and surrounds without worrying about timbre matching. There will be an 8" and 6" model coming as well.

No one really complains about a speakers width, just the depth for theater use. So I wanted to do something shallow like the 88-Special but with a more traditional look using a single woofer. After drawing things up, the waveguide that was one size bigger than the woofer fit just fine and allowed for a very shallow speaker enclosure. The 12" model is about 9.75" deep. That's really shallow for a speaker than can do over 120db.

The speakers weight was very important on these. About 2 months ago a friend I know at a cabinet company went to some industry show and while there looked at different types of light weight MDF. He found a company selling a high grade MDF that was Carb 2 compliant and ultra light weight. These are the first kits to use it. The cabinet without the front baffle weighs......like 16 pounds. The baffle is cut from a very dense highly refined 1" thick material that is not light weight. It's the heaviest "mdf" I've used and think it's actually hdf. The 12" Deltalite woofer is super light weight and the entire speaker should come in somewhere around 33 pounds.

Thank you, Brian--no buyer remorse on the Fusion 10's, very clean, effortless sound with enough efficiency to exceed reference level from an AVR. Although I wanted the 1899s, my wife chose the F10's as the maximum size she could deal with in the living room. They are WAF approved and will be my mains for decades to come.

The MTH series looks great for shelf mounting. They are light enough and shallow enough make it reasonable to allow that option. Geez, they could be used as surrounds also, make a nice match for the F10's.

F10's for mains, MTH10's for surrounds and Volts for height channels--take my money.

New DIYSG speakers: HTM-12 and HTM-10

These speakers sound great and with the cd used in these it will be a definite upgrade my room. I heard about 20 mins worth of demo material through them and think the avs diysg community will be really happy with these. I can't say enough about sound coming from them. Great job Matt on this new design!

I'm am But these speakers have me rethinking that. Time will tell I think I'm just excited since something new is out from diysg that I want to have in the room and can fit.

Also the same CD is being used in these as the 1299 after a quick search through diysg's website very cool!

@Erich H When you look at the baffle of the MTM12 is there room to cut off 1 inch on each side or 1/2'' inch on each side of it. I know a seperate box would have to made up for them and not use the flat pack. The reason I'm asking is my side colums are 16 inches wide I have plenty of space for depth and height so changes can be made
Thanks

You should be able to cut 1" off each side making it 16" wide but that only leaves 1/4" on each side of the waveguide cutout. The ports might not fit internally as it looks like they will be super close to the side walls at that width. Some filling down of the side walls around the ports might be needed. Or make the side walls from 1/2".

Presumably you heard the htm 10 and 12 at your last GTG? If so, does the htm 12 compare well to the F15? I'm asking because I will likely have to make a custom box if I went with the F15 kit due to space constraints. The htm 12 flat pack should easily fit. I will only be using these for mid/high with 4 sealed SI HT18D4's for subs.

Thanks

No these weren't at my GTG...I have no idea if they would compare to the fusion 15. Matt would have to answer that question. I heard these for a few mins when picking up subs after harassing Matt to let me listen to them. Afterwords we did talk about me having a another gtg meet after winter show casing some diysg speakers.
In my personal opinion after the limited time listening to them they would keep up with your 4 Ht -18's I have 4 my self in 4-20cubic ft slot ported boxes and know there output. I remember really liking the sound the cd had in the waveguide I was really impressed and the speaker itself to. This line of speakers will be a big hit with us diy and diysg guys I'm calling it now.

Yes, that's correct.

Eminence doesn't actually make an 8" Deltalite so it will be a custom model and likely be done after the 6" version. We're still debating if the 6" version should use the same compression driver. It would be overkill and make the price a bit high for that small speaker.......but it kind of makes sense to have the whole line use the same driver. It's a tough call.


There will be crossover boards and assembled crossover options eventually. I've got the flat packs for the 12" model, but the cabinet company hasn't told me how much they are yet.

I know most use Volts as surrounds, but will you have new editions to the Cinema line... smaller, similarly voiced speakers to use as surrounds for the 893, 1099, etc.?

I agree with your assessment abd greatly prefer wide and tall over deep. Deep speakers take up a lot of extra floor space. I found that out the hard way when I built a 24" × 24" × 24" subwoofer [a NeoDan EZ button design], I quickly wished I had changed the dimensions to make it taller and shallower.
