Morel Ultimate UW 1058 10" Subwoofer

What alignment (sealed or ported), and what volume would be required to get a decent in room response in the low 20's. Will be using my dbx PA2 and a pro audio amp of about 600 WPC, RMS 8 ohms. 

Asked by: SeanSLO
A volume of 1.75 cubic feet with a 3" diameter port that is 20" long will tune the enclosure to 20 Hz.

The Optimum volume for a vented enclosure comes to 1.41 c.f.  Does this volume include the deduction for the speaker itself?  And then most importantly; what sort of "vent" is under consideration?  Would a 3" port tube be possibility?

Asked by: submark
The volumes provided include driver and port displacement. A 3" port will work as long as it is flared, the recommended length is 22".

Would this be a good choice in a dipole open baffle H frame configuration? One facing forward the other,atop,facing rearward. Seperate midrange and tweeter set up with horns.

Asked by: tomward
These will have limited extension in an H frame application. I would recommend finding a woofer with a higher Qts, something at least 0.5 or higher which will require less EQ. We have many much less expensive options that will work better for this application.

Morel UW1058 10" Subwoofer - Sealed Cabinet Size?

I am busy constructing a cabinet for my Morel UW1058 Subwoofer using a Daytona SPA1000 Plate Amp. I have decided on a sealed cabinet for its low distortion properties and quality bass sound. What is the manufactures volume recommendation for sealed unit? My thoughts are around achieving the lowest possible frequency in my cabinet…
Asked by: Robert Dobson
The recommended sealed volume for this woofer is 0.6 cubic feet. This will provide an F3 of 47 Hz and F10 of 27 Hz.

Quad 10 bass cabinet

I have a 7 cubic ft. cab with 2 square ports that are 10" 3/4 W x 2" 1/2 H x 32" long the speaker chamber is 4 cubic ft. with 3 cube ft. in the ports. I built this for a custom 4 10" bass cab for pa use. I have 4 10' roadmaster woofers in there now and it hits hard but the frequency drops out around 40 to 45 hertz because of the roadmaster 10s. I want to have a woofer that will drop down to 20 hertz and wondering if this woofer x4 will give the the adequate frequency response I am looking for, now mind you the roadmasters are only 150 rms each compared to these. here is a pic of the cabs and my setup my mains are custom built too
Asked by: robertkehlerjr
Simple answer is no. These woofers are not only intended for a completely different environment but there is no reason to need anything lower than 35-40 Hz in a DJ/PA application. If you absolutely MUST have 20 Hz at the decible level most PAs like this are capable of, you will need multiple 21" woofers in specifically tuned boxes, or very large (think refrigerator size) horn loaded 18's and a ton of power for either option. If you want a slightly lower tune (35ish Hz) you will have to use a larger driver. A 10" woofer has a much higher free air resonance than a 15" or 18" and 18's can simply reproduce lower frequencies easier. You are not only limited by the woofers but the box itself is limiting. It is tuned to a certain frequency and it will stay that way regardless which woofers you decide to use. 98% of todays music will not go lower than 35 Hz. For a comparison, most comercial subwoofers regardless of woofer size are tuned in the mid to upper 40's, sometimes into the 50's. There is simply no reason for anything lower in this application.

Power Requirements

How many watts does this driver need to sound good in a sealed enclosure?Thanks,Dave
Asked by: wookus
Depends entirely on what you expect from it. If you just want to add a (very) smooth bottom end to a bedroom system, 20 watts would probably do it. For a low-volume car system, I'd start around 100. Home music, 200 would probably be decent, and for Home Theater use, you'd probably want 1kw or so.
