2 way with HF horn and 10-12" LF

[AudioGeek]

I am looking to make a 2way system with a HF horn and a regular 10-12" LF driver.

I do not know a lot about HF compression drivers, but so far have looked at:

Radian
Beyma
BMS
TAD

x-over point around 800hz. looking for wideband HF driver to 20Kz and flat response.

95-100 db sensitivity.

LF driver 10-12" but unsure yet which one or manufacter.

just like what I am interested in. My findings:
- you seem to be in USA, well then for flat HF driver up to 20khz , the ceramic magnet BMS 4590 is safe bet, for what you need a 2" exit horn. Can be bought for somewhat cheap at assistance audio as second hand / ex-demo .
- 18Sound have some high sensitivity 12" drivers what are suprisingly linear in the midbass region.

Im searching for an 1.4" HF driver to use with the 18Sound elliptical horn, the neodymium BMS 4594nd seems suited but expensive as well (like the rest of 1.4"-s except the "budget category" BMS 4554) .

BMS 4590P-16 New Old Stock $275.00ea at the mentioned site , one used went for 165 Eur on german ebay recently, fair.
i beleive BMS even sells passive x-over to match these at very low pricetag. Im not terribly interested in other HF drivers , would be nice to read an advice for 1.4" -s, esp. BMS 4554 .

Beyma CP755nD will do it.

If you want a super tweeter, I have a practically new set of BMS 4591s with the passive XOs that I need to sell.

BEYMA CP755/ND
Item Price: $595.99

you mean it would do the 800hz?

hmm Ti version is half the price at the local distrib (not bad at all) , and freq graph seems lot better too, worth a check !

[winslow]

They sound, to me atleast, very very nice. Only reason I have the 755nDs is that I got a DEAL on them. Paid pretty the price on US Speakers for both of them...and they were brand new in box. Since getting them, the BMS need to find a new home.

In the house, they should do 5-600 hertz. And they have real treble.

If I can get around the local tax , I can get the 2 Titanium for approx 454 Usd. Quite good !! Thanks for letting us know bout your experience .

Sorry to interfere in a good discussion ... those compression drivers are very effective ... 110db at least

Most bass oriented 10-12" PA/studio woofers are 95db, at the most ... if you are lucky to find a good one
With this size of drivers and baffle you might not need much BSC ... but I would still consider double woofers

yeah i have looked at the difference in sensitivity of the LF and HF drivers.

Thought i had was is to maybe run 2 LF drivers and have the BSC cutoff point at the 800Hz x-over point.

Add in an Lpad for the HF.

Originally i wanted to do a stand mount system. so, small cuft volume for LF driver. down to 50Hz maybe.

Thanks for info so far.

p.s. i do notice a droop in HF response of a lot of these compression drivers. Is this before adding a horn, and if so will the horn compensate for this?

Or do i need to find a flat response curve without the horn?


any ideas for good 10" and small cuft volume?
