Building a Multi-Purpose (Guitar AND Bass) Sealed 410 using Jensen Mod speakers

[blastjv]

I'd like to build a cabinet that will do the following things well (though I certainly realize that it might not be absolutely ideal for any of them):

- Practicing Guitar (mostly with a heavy overdriven sound, sometimes clean) alone in my basement at low volume with a 5w tube head (Blackstar HT-5).
- Practicing Bass alone in my basement at low volume using a 5w tube head (Blackstar HT-5).
- Practicing Bass alone in my basement at low volume with my 300w SVT-VR.
- Recording Bass or Guitar with either of those heads.
- Potentially playing Bass at smaller gigs with the SVT-VR.
- Maybe eventually building a matching cab (if I like this one enough) for times when it might be more convenient to use two of these instead of my SVT-810AV.

I think I'd like to build a simple SVT-ish 410 sealed cab using four Jensen Mod-10-70-16's wired as a switchable 4/16 ohm 280 watt cab. I wouldn't need or expect it to sound as huge as my 810. I'm thinking something about 24"x24"x14" or so.

Any thoughts from anyone about the feasibility of this project???


Thanks,

If you just make half an 8x10, with two compartments the same shape etc, it should sound the same, except 6db quieter (or maybe 3, I dunno if 3db if from the impedance drop and higher power with SS amps), but put it on a box so the speakers are same distance from your head as an 8x10. Alternatively, make a pair of 2x10s for having the same height and modularness.

For guitar practice and even gigs one Mod Ten is sufficient. For bass it takes three Mod Tens to equal the low end of one good bass ten, so all things considered I'd do a Mod 1x10 for guitar and a bass driver 1x10 for practice.

But is SVT type cab colouration an aim here, they don't do much actual low end.

Guitar coloration comes from pushing the drivers hard, and for basement practice or recording pushing a 4x10 hard ends up too loud. And in that application maybe even a 1x Mod Ten would have adequate output on bass.

I have four MOD10-50's in my SVT810E because 7/8 speakers were torn when I bought it for $75. The one without a tear had the whole magnet separate from the basket! I repaired the 4 least hurt torn ones with paper + rubber cement on the front and back. It's held up for over a year at this point. The MOD10-50's were based on a couple of people trying to replace the top 2 drivers with them. It opened up a high-mid emphasis in the cab. The stock drivers do the muddy Ampeg tone while the MOD's opened up the mid-highs. It never gets tweeter-bright though. I'd say do a 210x210 design. Two stock SVT bass drivers in an SVT410 and two MOD10-whatever power you want.
